Re: Replacement power transistors hfe.
The answer is that it depends on how the supply was designed.
A lower Hfe device will demand more base current from the device driving it. This device may overheat and fail as a result or it may be fine.
Post the circuit and we can calculate the effects. Also, a cheaper Si part may be a possibility.
