NASA Parts Selection List (NPSL)

MICROCIRCUITS
(Last Updated: November 9, 2009)

NOTE: Unless specifically stated within the parts selection tables of the NPSL, listing of a device technology herein does NOT imply/guarantee Radiation Hardness Assurance (RHA). Applications concerned with a device's ability to tolerate exposure to various forms of space radiation (e.g., total ionizing dose, single event effects, etc.) should be reviewed and have the device assessed by the Program's radiation assurance experts. The following resources may also be consulted for initial guidance:

NASA Goddard Radiation Effects and Analysis
Jet Propulsion Laboratory Radiation Effects

Level 1 Microcircuits
Level 1 microcircuits are defined as those currently qualified to

  • MIL-PRF-38535 "Integrated Circuits (Microcircuits) Manufacturing, General Specification for" as QML Class V or,
  • MIL-M-38510 "Microcircuits, General Specification for" as QPL JAN Class S or,
  • Space quality source control drawings (SCDs), where QML/QPL does not exist, which meet all of the technical requirements of MIL-STD-883, Method 5004 and 5005 for a Class S device
  • European Space Agency (ESA) SCC Level B Lot Acceptance Level 2 (LA2)
  • Japan Aerospace Exploration Agency (JAXA) QPL/QML Class I

Level 2 Microcircuits
Level 2 microcircuits are defined as those currently qualified to

  • MIL-PRF-38535 "Integrated Circuits (Microcircuits) Manufacturing, General Specification for" as QML Class Q or,
  • MIL-M-38510 "Microcircuits, General Specification for" as QPL JAN Class B, when modified/screened per mission requirements for space
  • European Space Agency (ESA) SCC Level C [Note 1]
  • Japan Aerospace Exploration Agency (JAXA) QPL/QML Class II

Notes:

1) ESA has gone to a single Level system based on ESA SCC Level B, so that new product will only be available as SCC Level B. ESA SCC Level C products may remain available for previously manufactured product while stocks last.

"For Reference Only": ARCHIVE of NPSL Detailed Microcircuit Listings

  • On November 9, 2009:  Updated the link for JAXA Qualified EEE Parts Database
  • On October 25, 2005 the microcircuit section of the NPSL was updated to reflect assorted editorial changes requested by the Japan Aerospace Exploration Agency (JAXA).  These changes included:
    • Change all references to "JAXA" from "National Aerospace Development Agency of Japan (NASDA)"
    • Delete references to NASDA PPL which has been inactivated by JAXA
    • Change references to "JAXA QPL/QML" from "NASDA QTS"
    • Delete all previously listed JAXA IC, transistor and diode parts listings (except for thin cell diode) due to decertification of these technologies by JAXA
    • Update contact info for JAXA EEE parts managers
    • Add link to JAXA Qualified EEE Parts Database for reference only
  • On April 21, 2003 the microcircuit section of the NASA Parts Selection List (NPSL) was updated to simplify the listing to show only the acceptable Levels (see above). This change has the effect of expanding upon the previous NPSL microcircuit section of acceptable part types without providing a detailed listing of part numbers and descriptions. Previous revisions of the NPSL microcircuit section used these same basic definitions for acceptable Levels, but also included a detailed list of part numbers, descriptions and sources. Due to the constant state of change in availability of qualified microcircuit technologies and associated sources, this type of detailed listing within the NPSL was never able to remain current. For this reason future updates to the NPSL will no longer attempt to maintain such a detailed listing for microcircuits. For "reference only" the detailed listing from the past NPSL microcircuit section has been retained as an archive. Users of the NPSL are advised that the archived listing forms only a small subset of the device technologies considered acceptable per the NPSL guidelines. In addition, the archive is not being maintained, therefore users should consult the latest QML or QPL for current qualification status of these devices.
