I don't recognize it as an HP part number - it's part of a digital panel meter that they bought as a sub assembly; it was made by Analogic in Wakefield, MA, rather than HP.

SeanB:
RCA house coded part, done so you went to the original manufacturer for replacement parts. But being made in 1974, not going to be a very beefy transistor, or anything special. Probably easy to replace with almost any NPN power device, like a TIP31C, which likely has plenty of SOA margin, seeing likely 5V supply has 15V input and no more than 1A load maximum, limited more by the heatsinking than anything else.
