Replacement for D41D2 / D40D2 Power transistors?

[muzikliberated]

Hey group.
I'm working on a very old psu circuit from an Oberheim SEM module.
D40D2 (NPN) / D41D2 (PNP) TO-202 power transistors are used here which I can't seem to find anywhere for a decent price.
I'm guessing that the circuit wouldn't be too fussed at a modern equivalent.

While maximum ratings differ, I'm looking at these as replacements, hoping for some advice as to whether I've chosen wisely or not. These seem over specced, which I'm hoping is a good thing.
I do see that all the max ratings on the D40D2 show as negative voltages though, where the chosen replacement shows positive maximums in its datasheet, which is worrying me.

thanks in advance, hope I posed my question well enough.

Those are general purpose medium power transistors so similar specs in same package should work. Confirm that the basing footprint is the same.

I recall using the ua723 way back when, it was one of the first voltage regulators.

Use the TIP29/31 family as replacement 1A, 40V

Looks like you found the perfect replacements, same pinout, same package, more Vc and I,

gain a little lower but should not matter in this application,


negative voltage is archaic way of denoting PNP instead of NPN

did you know that engineers still believe current flows from positive to negative?

lazy bastards don't want to re-write all the text books,

Thank you CJ!
And everyone!
