The KN2222 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 KN2222 is the KN2907.The FMMT2222 (SOT-23), FMMT2222R (SOT-23), KN2222S (SOT-23), KTN2222S (SOT-23), KTN2222U (SOT-323), MMBT2222 (SOT-23), PMBT2222 (SOT-23) and PMST2222 (SOT-23) is the SMD version of the KN2222 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KN2222 with the 2N4401, 2SC1008, 2SD471A, BC537, KN2222A, KSC1008, KSP2222A, KTC8050, KTN2222, KTN2222A, MPS2222, MPS2222A, MPS2222AG, MPS2222G, MPS3704, MPS650, MPS650G, MPS651, MPS651G, MPS6532, MPS6602, MPS6602G, MPSW01, MPSW01A, MPSW01AG, MPSW01G, NTE123AP, P2N2222A, P2N2222AG, PN2219, PN2219A, PN2222, PN2222A, ZTX449 or ZTX450.
