The PN2904 is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, base, and collector leads.
Here is an image showing the pin diagram of this transistor.The complementary NPN transistor to the PN2904 is the PN2218.You can replace the PN2904 with the 2SA708, BC527, BC528, KSA708, MPS6533, PN2904A, PN2906, PN2906A or ZTX552.
