I have a BC213 PNP transistor manufactured by Micro Electronics. I need to match this with a BC183 with a 5% tolerance for a project I'm working on. In my investigation I have found that the BC213 is considerably harder to come by than the BC183 even though they are both considered obsolete. So I'd rather not hunt down a different BC213.
My question is... in order to match the 2 transistors within a 5% tolerance would any BC183 do? Or do I need to find one manufactured by Micro Electronics as well. I have taken a peek at the datasheets for the ME versus the Fairchild Semi(which seems to be available some places). But with my limited knowledge I can't seem to tell whether or not they match up good enough. I'm not really sure what to look for in the datasheets.
Another question maybe simpler... when matching a PNP and NPN transistor within a 5% tolerance, what parameters in their specifications are most critical?
