Hello, all:
I got my hands on an unpopulated S100 motherboard by Vector
Electronics and I want to put it together for testing purposes. It's an
active-terminated board and I'm having trouble finding equivalent parts for
two transistors:
NPN power: GE D44C1 or NSI D44C4 (TO-220)
PNP power: GE D41D1 or NSI D45C4 (TO-202)(NSI is National
Semiconductor)
Any help would be appreciated.

Found some specs which should help to cross it
GE D44C1
Vce Max = 40
Veb Max = 5
Ic Max = 4 Amps
Power Max = 30 Watts
Junction Temp Max = 150 Degrees C
Freq Resp = 50 MHz
Cuttoff = 10 uA at Vcb=40
Hfe=37 at .2 Amps
GE D41D1
Vce Max = 45
Veb Max = 5
Ic Max = 1 Amp
Power Max = 6 Watts
Jumction Temp Max = 150 Degrees C
Freq Resp = 150 MHz
Cuttoff = 100 nA at Vcb=45
Hfe=88 at .1 Amp
