MIL SPEC Parts Availability
MIL SPEC Parts Availability
(OP)
All,
I am working with an electronics design house on a project that might require parts to be Mil Spec. They are saying that most components are no longer Mil Spec. That the market has moved everthing to Automotive grade. What's the deal? Is this true and what is the rational for this move?
Regards,
Rich...

RE: MIL SPEC Parts Availability
Background was that the reliability of commercial/industrial/automotive parts had become so good that the US DoD allowed the use of such components. This also represented a big cost saving.
Accordingly, a lot of electronic component manufacturers then closed their MIL product lines, as sales broke away.
Of the big semi manufacturers, I believe TI is the only one to still have a MIL line.
One route is to use automotive parts, which today have very high reliability.
Another is to specify aerospace parts, which still exist, but be prepared to bring the REALLY big wallet.

Automotive and industrial grade is as good as it gets these days. Wev'e got systems where we're putting in heaters because we don't know whether the parts will operate correctly at less than -40ÂșC.

For new designs, it might be better to determine the actual root requirements (such as temperature) and meet those.
Amusingly, sometimes new parts often become obsolete much faster than old parts. Probably easier to find parts to restore a 60-year old radio than a 20-year old computer.
RE: MIL SPEC Parts Availability
If it's REALLY mission critical, the customer has to cough up some money. Or find stashes of old parts But, bear in mind that most old parts have no certs.

If they want to sell cars in many parts of Canada, then they'd better work at -40C.
