         if you have a source or supply of these parts:
 Part #=5962H9954103QXC
 
That's not a chip, it's a hybrid multi-chip module. Probably just about
unobtanium now. If a datasheet is available, it wouldn't be hard to
engineer a form/fit/function replacement, if it's for ground support and
you don't need radiation-hardened or mil-spec.  If no datasheet, could
design from schematics of board it is used on.  If no datasheet and no
schematics...
