SS8550 D331 Transistor Answered

Hi , Guys can you tell me if  2N2222 Transistor is equal ant to SS8550 . It's in an IR circuit .

Thanks in advance :D


Next time try to use a more suitable section and you might get get more/better answers ;)

You can use 2N2907A on place of SS8550

You can get the datasheet here:


No they are not the same or similar 2N2222 is an NPN transistor and a SS8550 is a PNP transistor. The complmentry to SS8550 is SS8050 and it is closer to 2N2222.
