Finding cross references for this sort of number is next to impossible
because these are "house" numbers - assigned to these parts by the
Motorola Communications parts department when each new product is
engineered.
Motorola Communications Division has never published a cross reference
between their in-house numbers and the actual manufacturer's part
numbers. In some cases there wouldn't be a cross anyway because the
parts are made to spec - or graded from a basic industry number.
If your PA is an MSF/PURC5000 type - the Motorola service manual does
not recommend replacing the transistors and did not have part numbers
for ordering replacements to that component level - the recommended
repair procedure is to replace the substrate assembly which comes with
the transistor factory installed.
Some of those assemblies are probably still available - otherwise you
might try calling one of the RF parts suppliers - they may have
identified suitable replacement transistors for specific applications.
