Replacement Part for D751 transistor

Hello. I’m trying to repair a headlight popup relay control board for my 1985 Toyota MR2.

I believe I’ve found a shorted transistor. The part number is D571.

I believe this is a 2SD571 transistor. Is this part available on DigiKey? If not is there a newer replacement part number that would work?

Hi @Will_F ,

As 2SD571 is an audio transistor, which is then used in a relay board, suggests that it is just doing some switching action etc., thus could assume that any device with similar specs will do.

You could perhaps try this one (identical pin order):
