The MPSA18 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.You can replace the MPSA18 with the KSP05, KSP06, MPS651, MPS651G, MPSA05, MPSA05G, MPSA06, MPSA06G, MPSA18G, MPSW05, MPSW05G, MPSW06, MPSW06G, ZTX690B or ZTX692B.The MPSA18G transistor is the lead-free version of the MPSA18.
