Haven't been able to find an equivalent so far.

Can you post a clear close-up photo of it? How is it marked?

It' an approx. 1/8 in. diameter transistor that I haven't un soldered yet. I doubt my camera could get any
useful pic of it.

Well, it is an HP 1855-0368.

Which crosses to Siliconix FN2861 or National Semi SF55042, neither of which seems to be current production. I haven't yet found a datasheet for either. Sphere.bc has the original HP part in new and used.

You mean ALL the numbers in electronics are important? Just kidding --thanks for your help.
