Like all Devices used in space, the equipment must also meet the stringent testing for outgassing (the release of trapped air) and residual magnetism to be suitable for use in space applications. These guidelines are set by Nasa\u2019s EEE-INST-001 guidelines for reliability.<\/p>\n<p>The NASA EEE-INST-001 has laid out three reliability levels of equipment that can be used for several space explorations. The term &nbsp;\u201cLevel\u201d is attached to each component. A Level 1 Part has the highest performance &amp; reliability while a Level 3 part has the lowest.&nbsp;<\/p>\n<ul>\n<li>A reliability Level 1 part has the highest manufacturing control and testing per military or DSCC specifications and low-risk parts for missions 5 years or longer.&nbsp;<\/li>\n<li>Level 2 part has reduced manufacturing control and testing for mission duration being 1-5 years.&nbsp;<\/li>\n<li>Level 3 Part has no guaranteed reliability controls in the manufacturing process and no standardized testing requirements for programs with a mission duration of less than 1 year and up to 2 years. The reliability of the level 3 part can vary significantly with each manufacturer, part type, and LDC due to unreported and frequent changes in design, construction, and materials and they are more likely to fail than the level 1 part.<\/li>\n<\/ul>\n<p>EEE Parts are specified in the following table for each Federal Stock Class (FSC).

Not all military specifications are acceptable for space applications. Unless specifically allowed By the NASA EEE INST 001 Document, it is the responsibility of the user or the engineer to ensure that the aforementioned equipment and other military specifications satisfy the requirements<\/li>\n<li><strong>Source Control Drawings (SCDs):<\/strong> This designation includes parts that are procured to a user-controlled specification or custom requirement such as an SCD. The SCD shall include the screening and qualification requirements. in addition to performance parameters, absolute maximum ratings, case outline, terminal description, and other unique requirements. The testing required by the SCD is to be performed by the manufacturer and does not have to be repeated by the user. If an acceptable government-controlled specification is not available for Level 1 programs, an SCD is required along with all the other mentioned testing parameters which shall yield successful results.<\/li>\n<li><strong>Manufacturer High Reliability<\/strong>: This part designation includes parts intended for high-reliability applications which are procured to a manufacturer-controlled test program as described in the manufacturer\u2019s catalog. They are controlled only by the manufacturer, who assigns them a special part number and provides a certificate of compliance that they have been tested as advertised.<\/li>\n<li><strong>Commercial:<\/strong>&nbsp; &nbsp;Commercial\/consumer parts should be avoided in space applications. Some high-reliability commercial parts, such as Automotive Quality System (AQS) parts, may be acceptable for space applications. It is the responsibility of the user to understand and document the applicable specification or test plan requirements.<\/li>\n<\/ul>\n<p><strong>Screening:<\/strong>&nbsp; Screening tests are intended to remove nonconforming parts, parts with random defects, or parts likely to experience infant mortality, from an otherwise acceptable lot and thus increase confidence in the reliability of the parts selected for use. Screening tests shall be performed on flight parts. These tests are in addition to tests performed by the manufacturer for each part designation. Screening tests shall be performed in the order shown unless otherwise indicated. The user or Engineer is responsible for specifying the device\u2019s unique requirements if any.<\/p>\n<p><strong>Qualification:&nbsp;<\/strong>Qualification testing consists of mechanical, electrical, and environmental inspections and is intended to verify that materials, design, performance, and long-term reliability of the part are consistent with the specification and intended application, and to assure that manufacturing processes are controlled. Qualification by usage history or similarity to qualified parts may be acceptable as discussed below.<\/p>\n<ul>\n<li><strong>History<\/strong>: A part can be considered qualified if it has been successfully used in<\/li>\n<\/ul>\n<p>(a) applications identical to that proposed (heritage design) or&nbsp;<\/p>\n<p>(b) applications different than that proposed, if the application, including derating and environmental conditions, is fully documented and is more severe than the proposed application.&nbsp;<\/p>\n<p>The part must have been used for 2 years minimum total operating time in orbit. The part must have been built by the same manufacturer in the same facility using the same materials and processes as an equivalent SCD. It is the responsibility of the user to have such evidence documented.&nbsp;<\/p>\n<ul>\n<li><strong>Similarity:&nbsp;<\/strong>A part can be considered qualified if it is similar to a part for which qualification test data exists, and the test data \u2013<\/li>\n<\/ul>\n<p>(a) satisfies the requirements specified herein for the applicable part level, and&nbsp;<\/p>\n<p>(b) is available and is less than 2 years old relative to the lot date code of flight parts. To be considered similar, the part shall be made by the same manufacturer on the same manufacturing line or a line with only minor differences, and these differences shall be documented and shown to represent no increased reliability risk.<\/p>\n<ul>\n<li><strong>Existing Test Data<\/strong>: Parts can be qualified by existing test data that meets the requirements (a) Lot Specific Data indicates that flight parts have the same lot date code as the qualification samples. Lot-specific data is always acceptable in place of qualification testing when it meets the requirements specified herein.<\/li>\n<\/ul>\n<p>&nbsp;(b) Generic Data is an acceptable basis for qualification if it is less than one year old relative to the lot data code of flight parts, and is acquired and reviewed for acceptability by the user. The user shall also verify that the data is representative of flight parts: e.g., built in the same facility using identical or equivalent processes.<\/p>\n<p><strong>Audits &amp; Customer Source Inspection (CSI)<\/strong><\/p>\n<ul>\n<li><strong>Audits:<\/strong> Audits are not necessary for all parts &amp; equipment. However, for Level 1 and Level 2 parts, a site visit to assess the manufacturer\u2019s capability in satisfying the requirements specified herein is recommended for unproven manufacturers. The term \u201cunproven\u201d means that the user has not previously procured parts from the manufacturer, or that the manufacturer has not established a history of supplying reliable parts for space applications. The user is encouraged to consult the NASA Core Suppliers List (CSL) on the World Wide Web for technology, process, and audit information on approved suppliers, and audit\/CSI requirements for \u201cunproven\u201d manufacturers.<\/li>\n<li><strong>Customer Source Inspection (CSI):&nbsp;<\/strong>CSI is not a requirement but is recommended for unproven parts intended for use in Level 1 and Level 2 applications, and parts of manufacturers with a known problem history. CSI is most effectively performed at precap visual inspection and the final electrical test. If CSI is used as a substitute for required data (i.e., data is reviewed at the manufacturer\u2019s facility rather than acquired by the user), then the CSI shall be fully documented in a trip report. This should summarize the data and reference manufacturer test reports by number.<\/li>\n<\/ul>\n<p><strong>Click here to learn more about Space Qualified Capacitors.<\/strong><\/p>\n<p><strong>Click here to learn more about Space Qualified Oscillators.<\/strong><\/p>\n<p><strong>Click here to learn more about Space Qualified Diodes.<\/strong><\/p>\n<p><strong>Click here to learn more about Space Qualified Transistors.<\/strong><\/p>\n<p><strong>Click here to learn more about NASA EEE-INST-002 Standard.<\/strong><\/p>\n<div class=\"customDataWidget\" data-designid=\"d5\" data-h1=\"Space Qualified Oscillator Manufacturers\" data-url=\"https:\/\/www.satnow.com\/directory\/oscillators\" height=\"213px\" width=\"768px\">\n<div class=\"widget-layout directory-widget-one my-3\">\n<h4 class=\"heading txt-18\">Space Qualified Oscillator Manufacturers <small>(View All)<\/small><\/h4>\n<ul class=\"list-unstyled owl-carousel owl-theme designOneSlider mb-0 owl-loaded owl-drag\">\n<div class=\"owl-stage-outer\">\n<div class=\"owl-stage\" style=\"transform: translate3d(0px, 0px, 0px); transition: all 0s ease 0s; width: 1383px;\">\n<div class=\"owl-item active\" style=\"width: 162.831px; margin-right: 10px;\">\n<li>\n<div class=\"dirctory-image img-thumbnail p-0\"><img decoding=\"async\" src=\"https:\/\/cdn.satnow.com\/live\/1399_1399_quartzlock_638134191672590243_200.PNG\" alt=\"Quartzlock\"><\/div>\n<h5 class=\"mt-2 txt-13\"> Quartzlock<\/h5>\n<\/li>\n<\/div>\n<div class=\"owl-item active\" style=\"width: 162.831px; margin-right: 10px;\">\n<li>\n<div class=\"dirctory-image img-thumbnail p-0\"><img decoding=\"async\" src=\"https:\/\/cdn.satnow.com\/live\/aaa_638971599683065321_638971599683065321_300.jpg\" alt=\"Axtal GmbH\"><\/div>\n<h5 class=\"mt-2 txt-13\"> Axtal GmbH<\/h5>\n<\/li>\n<\/div>\n<div class=\"owl-item active\" style=\"width: 162.831px; margin-right: 10px;\">\n<li>\n<div class=\"dirctory-image img-thumbnail p-0\"><img decoding=\"async\" src=\"https:\/\/cdn.satnow.com\/live\/14022_wi2wi_638134191708527759_200.PNG\" alt=\"Wi2Wi\"><\/div>\n<h5 class=\"mt-2 txt-13\"> Wi2Wi<\/h5>\n<\/li>\n<\/div>\n<div class=\"owl-item active\" style=\"width: 162.831px; margin-right: 10px;\">\n<li>\n<div class=\"dirctory-image img-thumbnail p-0\"><img decoding=\"async\" src=\"https:\/\/cdn.satnow.com\/live\/1946_raltron_electronics_639104401495518024_200.png\" alt=\"Raltron Electronics\"><\/div>\n<h5 class=\"mt-2 txt-13\"> Raltron Electronics<\/h5>\n<\/li>\n<\/div>\n<div class=\"owl-item\" style=\"width: 162.831px; margin-right: 10px;\">\n<li>\n<div class=\"dirctory-image img-thumbnail p-0\"><img decoding=\"async\" src=\"https:\/\/cdn.satnow.com\/live\/1236_safran_group_638833356431756626_200.jpg\" alt=\"Safran Group\"><\/div>\n<h5 class=\"mt-2 txt-13\"> Safran Group<\/h5>\n<\/li>\n<\/div>\n<div class=\"owl-item\" style=\"width: 162.831px; margin-right: 10px;\">\n<li>\n<div class=\"dirctory-image img-thumbnail p-0\"><img decoding=\"async\" src=\"https:\/\/cdn.satnow.com\/live\/1095_1095_genmix_technology_638134186280584072_200.png\" alt=\"Genmix Technology\"><\/div>\n<h5 class=\"mt-2 txt-13\"> Genmix Technology<\/h5>\n<\/li>\n<\/div>\n<div class=\"owl-item\" style=\"width: 162.831px; margin-right: 10px;\">\n<li>\n<div class=\"dirctory-image img-thumbnail p-0\"><img decoding=\"async\" src=\"https:\/\/cdn.satnow.com\/live\/17_orbital_research_639093388038908005_200.png\" alt=\"Orbital Research\"><\/div>\n<h5 class=\"mt-2 txt-13\"> Orbital Research<\/h5>\n<\/li>\n<\/div>\n<div class=\"owl-item\" style=\"width: 162.831px; margin-right: 10px;\">\n<li>\n<div class=\"dirctory-image img-thumbnail p-0\"><img decoding=\"async\" src=\"https:\/\/cdn.satnow.com\/live\/1082_1082_microchip_technology_638134185940271420_200.jpg\" alt=\"Microchip Technology\"><\/div>\n<h5 class=\"mt-2 txt-13\"> Microchip Technology<\/h5>\n<\/li>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"owl-nav\"><button type=\"button\" role=\"presentation\" class=\"owl-prev disabled\"><span aria-label=\"Previous\">\u2039<\/span><\/button><button type=\"button\" role=\"presentation\" class=\"owl-next\"><span aria-label=\"Next\">\u203a<\/span><\/button><\/div>\n<div class=\"owl-dots\"><button role=\"button\" class=\"owl-dot active\"><span><\/span><\/button><button role=\"button\" class=\"owl-dot\"><span><\/span><\/button><\/div>\n<\/ul>\n<\/div>\n<\/div>\n<p style=\"text-align: center;\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The NASA EEE-INST-001 provides instructions for choosing Capacitors, Crystal Oscillators, Diodes and Transistors, Fiber Optics, Filters, Fuses, Microcircuits, Magnetics, Relays, Resistors, Thermistors, Wire and Cable based on mission needs and requirements.&nbsp; To qualify for certain specific missions, the parts or equipment must be tested and approved by NASA under the NASA EEE-INST-001.
