MIL-PRF-38535K
3.6.2 Part or identification number (PIN). Each QML microcircuit shall be marked with the complete PIN. The PIN may be
marked on more than one line provided the PIN is continuous except where it "breaks" from one line to another. As of revision
B of MIL-PRF-38535, several types of documents are acceptable for use when specifying QML microcircuits. They are MIL-M-
38510 device specifications and SMD. The PIN marked on those parts under QML shall be the same as when supplied by the
manufacturer prior to being listed on the QML-38535. The "Q" or "QML" designator combined with the listing of that PIN on a
particular vendors QML listing shall indicate the fact that the manufacturer of the device is QML certified and qualified for the
processes used to build that product. The PIN system shall be of one of the following forms, as applicable to the SMD or MIL-
M-38510 device specification used for production:
a. SMD PINs shall be as follows:
5962 1/
- or M,D,P,L,R,F,G,H

For packages where marking of the entire SMD PIN and all other required topside markings are not possible due to space
limitations, the manufacturer has the option of leaving the “5962-“ off the marking. The allowance for optional marking will be
indicated in the individual SMD. For RHA product using this option, the RHA designator shall still be marked.
b. Device specification documents, originally published prior to 27 July 1990, shall be as follows:

All new PINs specified by new documents, originally published after 27 July 1990, shall be in accordance with the one part-one
part number system.
All PINs specified by existing device specifications with the number assigned prior to 27 July 1990, may use either the original
assigned PIN or the one part one-part number system with the first two digits in the drawing designator being "38" and the last
three being the device specification number (e.g., M38510/00101BAC shall become 5962-3800101BAC).
________
1/ Drawings initiated prior to 1986 may not contain a federal stock class designator.
2/ Low dose rate sensitivity shall be indicated in the device specification for those devices that are susceptible to enhanced
low dose rate sensitivity (ELDRS) effects. For device type series that are marked 61, 62, 63, and so forth, the designator
shall indicate that the device has been characterized/tested for ELDRS and is ELDRS sensitive.
3/ Non one-part SMDs do not contain a device class designator. See MIL-HDBK-103 for qualification information. Prior MIL-
M-38510 device specifications converted to SMDs shall contain a B or S class designator.
