I have found that but-for a very few specialized transistors, most of the
general purpose types are now lumped into a much smaller universe of
replacement types. I have never had any problems, ultimately, with finding
replacements - and I keep a variety of testers and checkers to make sure
they will do - but they are not necessarily to OEM spec. Usually much
better.
This particular one was an NPN with an ft of 1400 MHz and 1.2 pF Cob. So,
definitely, a 2N2222 would not cut it.
