The 2N2925 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 BC848 (SOT-23), BC848B (SOT-23), BC848BW (SOT-323), BC848W (SOT-323), BC849 (SOT-23), BC849B (SOT-23), BC849BW (SOT-323), BC849W (SOT-323) and MMBTH10 (SOT-23) is the SMD version of the 2N2925 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2N2925 with the 2N4124, 2N5172, 2N5210, HS945, KSC945, KTC9014, KTC9014C, MPS3395, MPS3415, MPS3417, MPS650, MPS650G, MPS6532, MPS6601, MPS6601G, MPS6602, MPS6602G, MPSW01, MPSW01A, MPSW01AG, MPSW01G, NTE192, S9014, S9014C, SS9014, SS9014C or ZTX690B.
