The MPSW42 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 MPSW42 is the MPSW92.The KST42 (SOT-23), MMBTA42 (SOT-23) and PZTA42 (SOT-223) is the SMD version of the MPSW42 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the MPSW42 with the 2N6516, KSP42, MPSA42, MPSW42G or ZTX457.The MPSW42G transistor is the lead-free version of the MPSW42.
