I needed 2N3904 transistors, so I went to the few (poor) electronics shops we find in my country. They didn't have those, but they gave me 2N9013 and stated that those were equivalent NPN transistors. Both in TO-92 packages.
I've searched for a datasheet and found one from Promax-Johnton (who?) with "1W OUTPUT AMPLIFIER OF POTABLE RADIOS IN CLASS B PUSH-PULL OPERATION" which is worse than Chinese to me.
My questions are:
- Is the 2N9013 a good replacement for my 2N3904?
- What additional considerations I need to be aware?
