hello friends,
can any guess me an equivalent transistor for 2SC2078,

can i use BD243C as an alternative?
i have attached the data sheet for both 2SC2078 and BD243C.

Hello,

I would say no.
The 2sc2078 is an RF transistor.
In the datasheet of the BD243C there is no maximum frequency given.
The BD is an audio transistor, as far as I know.

Greetings,
Bertus
