[F5UL]

Hello Rick

I think that for HF use both transistors are equivalent
Here are the main caracteristics :

2N4124

Max Dissip 310 mW
BVCBO 30 V
BVCEO 25 V
BVEBO 5 V
IC Max 200 mA
hfe 120 Mhz

2N3904

Max >Dissip 310 mW
BVCBO 60 V
BVCEO 40 V
BVEBO 6 V
IC Max 200 mA
hfe 100 Mhz

Data extracted from "D.A.T.A. Inc Reference Standards for Industriy

Hope this will help your choice !
Regards F5UL/Bob
