The 2N6429 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 MMBT6429 (SOT-23) is the SMD version of the 2N6429 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2N6429 with the KSP05, KSP06, MPS651, MPS651G, MPSA05, MPSA05G, MPSA06, MPSA06G, MPSA18, MPSA18G, MPSW05, MPSW05G, MPSW06, MPSW06G, ZTX690B or ZTX692B.
