It should be correct hopefully. Mar 12, 3. Buying and general tech. All I need to know. OR if you don’t have that, use the diode checker, there be junctions in there! First, check out our list of national and global suppliers. Im looking for a equivalent to a BF, I understad i could use a 2N is that right?

Transistor equivalent for bf494 & bc548

It looks like a pretty generic NPN transistor, so unless the circuit is picky, I’d expect pretty much any generic NPN would be fine, so long as you pay attention to what the circuit demands are. No generic ‘which is best’ and ‘where to buy’-type questions please.
