I assume what you meant to say was :-
Is there an equivalent part to the 2N4125 and 2N5952 listed on this site.
Well without knowing what you want to do with the transistors it is impossible to say.
The 2N4125 is a general purpose PNP transistor so I suspect the BC558B would probably do.
However, the 2N5952 is an RF N channel FET and while there are small signal FETs listed here I don't know what parameters of the FET you need. Do not however use a high current FET.
