The PN2218 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 PNP transistor to the PN2218 is the PN2904.You can replace the PN2218 with the BC537, PN2218A, PN2221 or PN2221A.
