The KSP2222A 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 KSP2222A is the KSP2907A.The DXT2222A (SOT-89), DZT2222A (SOT-223), FJX2222A (SOT-323), FMMT2222A (SOT-23), FMMT2222AR (SOT-23), KN2222AS (SOT-23), KST2222A (SOT-23), KTN2222AS (SOT-23), KTN2222AU (SOT-323), MMBT100 (SOT-23), MMBT2222AT (SOT-523F), MMST2222A (SOT-323), PMBT2222A (SOT-23) and PMST2222A (SOT-23) is the SMD version of the KSP2222A transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSP2222A with the 2N4401, 2SC1008, BC537, BC538, KN2222A, KSC1008, KTN2222A, MPS2222A, MPS2222AG, MPS650, MPS650G, MPS651, MPS651G, MPSW01A, MPSW01AG, NTE123AP, P2N2222A, P2N2222AG, PN2219A, PN2222A, PN4033 or ZTX450.
