choice of case outlines and lead finishes which are available and are reflected in the Part or Identifying Number (PIN). When
available, a choice of radiation hardness assurance levels are reflected in the PIN.

1.2.3 Device class designator. This device class designator shall be a single letter identifying the product assurance level. All
levels are defined by the requirements of MIL-PRF-38534 and require QML Certification as well as qualification (Class H, K, and
E) or QML Listing (Class G and D). The product assurance levels are as follows:
Device class
K
Device performance documentation
Highest reliability class available. This level is intended for use in space
applications.
Standard military quality class level. This level is intended for use in applications
where non-space high reliability devices are required.
Reduced testing version of the standard military quality class. This level uses the
Class H screening and In-Process Inspections with a possible limited temperature
range, manufacturer specified incoming flow, and the manufacturer guarantees (but
may not test) periodic and conformance inspections (Group A, B, C, and D).
Designates devices which are based upon one of the other classes (K, H, or G)
with exception(s) taken to the requirements of that class. These exception(s) must
be specified in the device acquisition document; therefore the acquisition document
should be reviewed to ensure that the exception(s) taken will not adversely affect
system performance.
Manufacturer specified quality class. Quality level is defined by the manufacturers
internal, QML certified flow. This product may have a limited temperature range.
