• The MPS918G is the lead-free version of the MPS918 transistor

The MPS918G 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 MMBT918 (SOT-23) is the SMD version of the MPS918G transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the MPS918G with the 2N2923, 2N2924, 2N2925, 2N4123, 2N4124, 2N5088, 2N5089, 2N5172, 2N5963, 2SC1209, 2SC1209-C, 2SC1209-D, 2SC1209-E, 2SD227, 2SD227G, 2SD227O, 2SD227Y, 2SD261, 2SD261G, 2SD261O, 2SD261R, 2SD261Y, 2SD471A, 2SD471AG, 2SD471AO, 2SD471AY, KN2222, KSD227, KSD227G, KSD227O, KSD227Y, KSD261, KSD261G, KSD261Y, KSD471A, KSD471AG, KSD471AY, KSP13, KSP14, KTC8050, KTC8050C, KTC8050D, KTC9013, KTC9013D, KTC9013E, KTC9013F, KTC9013G, KTC9013H, KTC9013I, KTN2222, M28S, M28S-B, M28S-C, M28S-D, M8050, M8050-C, M8050-D, MPS2222, MPS2222G, MPS2369A, MPS3392, MPS3393, MPS3394, MPS3395, MPS3414, MPS3415, MPS3704, MPS3705, MPS3706, MPS4123, MPS4124, MPS6512, MPS6513, MPS6514, MPS6515, MPS6520, MPS6521, MPS6532, MPS6560, MPS6560G, MPS6561, MPS6601, MPS6601G, MPS6602, MPS6602G, MPS8050, MPS8050B, MPS8050C, MPS8050D, MPS918, MPSA13, MPSA13G, MPSA14, MPSA17, MPSH10, MPSW01, MPSW01G, MPSW13, MPSW14, PH2369, PH2369A, PN2218, PN2219, PN2221, PN2222, PN3563, PN918, S8050, S8050B, S8050C, S8050D, S9013, S9013D, S9013E, S9013F, S9013G, S9013H, S9013I, SS8050, SS8050B, SS8050C, SS8050D, SS9013, SS9013D, SS9013E, SS9013F, SS9013G, SS9013H, ZTX449 or ZTX689B.
