2n4401 vs 2n4124

Do you have a technical question that doesn't really fit a specific console? Want some general info on electronics, hacking, making cookies, etc? Here's the place to ask! Go nuts.

Will a 2n4124 work in place of a 2n4401 for the video booster? I couldnt get a 2n4401 from anywhere near me but they had one of these at my school so i grabbed it for .50 cents.

2n4124 specs
Symbol Parameter Value Units
VCEO Collector-Emitter Voltage 25 V
VCBO Collector-Base Voltage 30 V
VEBO Emitter-Base Voltage 5.0 V
IC Collector Current - Continuous 200 mA
TJ, Tstg Operating and Storage Junction Temperature Range -55 to +150 °C

2n4401 specs
Symbol Parameter Value Units
VCEO Collector-Emitter Voltage 40 V
VCBO Collector-Base Voltage 60 V
VEBO Emitter-Base Voltage 6.0 V
IC Collector Current - Continuous 600 mA
TJ, Tstg Operating and Storage Junction Temperature Range -55 to +150 °C

I'm not sure what "the video booster" is, but I'm going to co ahead and assume it's a low-power application. Both of these transistors are probably overpowered in terms of the maximum voltage and current they can handle. 2n4401 has a sightly lower bandwidth, (250 MHz vs 300 MHz) but it should be just fine.
