The S9014B 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 S9014B transistor can have a current gain of 100 to 300. The gain of the S9014 will be in the range from 60 to 1000, for the S9014A it will be in the range from 60 to 150, for the S9014C it will be in the range from 200 to 600, for the S9014D it will be in the range from 400 to 1000.The complementary PNP transistor to the S9014B is the S9015B.The 2SC1623 (SOT-23) and KSC1623 (SOT-23) is the SMD version of the S9014B transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the S9014B with the 2SC1008, 2SC1211, 2SC815, BC537, BC538, HS945, KSC1008, KSC815, KSC945, KSP05, KSP06, KSP8098, KSP8099, KTC9014, KTC9014B, MPS651, MPS651G, MPS8098, MPS8098G, MPS8099, MPS8099G, MPSA05, MPSA05G, MPSA06, MPSA06G, MPSW05, MPSW05G, MPSW06, MPSW06G, PN100, PN2484, PN4033, SS9014, SS9014B or ZTX450.
