Well,  the key things I see here are:

1) All automotive ECU's I've looked at  have had Commercial grade
components - and failure of these is very  rare.

2) Most components I have selected (thus far) have Commercial  and
occaisionally Industrial temperature ranges - can I select  different
parts - perhaps. I have not found any which support Military  grade - and
my read through Digi-Key and Jameco don't show any Military  grade parts
(I haven't read both entire catalogs - but of what I have read  - not a
single part).

3) Least important to me is any additional  cost - and from what I've
seen thus far the difference between cost for  Commercial to Industrial
is fairly trivial.

So, unless someone can  point me to obtainable in qty 1 Mil spec parts I
will use Industrial where  available and Commercial where I must...




All the electronic manufacturers' catalogs I have seen list CMOS parts as  
meeting mil.spec.
