I=20 have to mod only about 125 units, so seems reasonable to try. Gain=20 is similar to a 2n4401 and the device sees only 12Vdc, so looks to be=20 a good fit. Saw that Digikey had another similar part that I wish I had found=20 years ago: 2SD2259. This is also a NPN device but has hfe of 1000 to=20 2500 (min / max) - and its NOT a darlington device (Vbe is shown as=20 about 0.6V), saturation voltage is typical 0.4V @ 50mA. That's a LOT=20 of gain! I'm gonna grab some just to have around .
