• The MPS651G is the lead-free version of the MPS651 transistor

The MPS651G 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 MPS651G is the MPS751G.The BSP51 (SOT-223), FMMT491 (SOT-23), FMMT491Q (SOT-23), KTC4378 (SOT-89), KTC4378GR (SOT-89) and KTC4378Y (SOT-89) is the SMD version of the MPS651G transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the MPS651G with the MPS651.
