So I am building a board that calls for two BC850 transistors in a TO92 style package. This is a bipolar NPN transistor. I really don't know a lot about transistors so please bear with me. I looked everywhere for BC850, but I've completely struck out finding any in the TO92 style package. I find some in an SMD package, but that would be ugly to adapt. I tried googling equivalents, but what I found was mostly either other stuff I can't find or things that are also not readily available in a TO92 package.
My question for anyone who knows about this stuff is whether other Bipolar NPN transistors that I have on hand in a TO92 package like a 2N2222 or a 2N3904 would work? Maybe a stupid question, I can see that it might depend a lot on the circuit in question. I'm wondering maybe even which one might be the more likely choice of those two if I was going to just try it.
Unfortunately I don't know how to get ahold of the people who designed the board. When I google it I mostly find youtube videos and web pages and stuff that appear to be in Russian.
