Yes and No.

TDA1545 and TDA1543 are pin compatible, but not replacable. You should change/remove the caps and/or resistors on the Vref pin (7). But this would probably be the waste of time.

Generaly speaking, you could swap it also with TDA1541, but that demands more work. You’ll need new pcb and new supply for DAC, and also new analog stage.
