M 9763 transistor

[ka1nvz]

Does anyone know what a Motorola transistor marked M9763 might cross reference too? Keep in mind it is in a TO-220 style case with the leads marked E B C on the heat sink fin. The closest thing I came up with is a NTE 290A but this it isn't the same case style. The transistor came out of a Motorla bench power supply model #S1347D.

Definitely NOT an NTE290A, as that is a PNP transistor, and the M9763 is an NPN.
Also it's a TO-202N package.
Other than that I can't say, I could find no cross references or data for it.

The original Motorola part# would be 48-869763

I tried searching on that, but didn't find anything.

I went through our old stock but came up short (found a M9762, soooo close).

Did someone post some inro about using a NTE 291 in place of the 9763?

NTE 291 is a different package and pinout, so you'd have to account for that.
It's rated at 130 volts, 4 amps, so it should be able to handle whatever the M9763 was doing as far as those are concerned. As long as the Hfe (Beta) is high enough it would probably work.

It would help to have some idea what part of the circuit it is being used in, for example, as a driver or a reference amplifier. A schematic would be even better.
