The KTC9012I 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 KTC9012I transistor can have a current gain of 176 to 246. The gain of the KTC9012 will be in the range from 64 to 246, for the KTC9012D it will be in the range from 64 to 91, for the KTC9012E it will be in the range from 78 to 112, for the KTC9012F it will be in the range from 96 to 135, for the KTC9012G it will be in the range from 118 to 166, for the KTC9012H it will be in the range from 144 to 202.The complementary NPN transistor to the KTC9012I is the KTC9013I.The 2SA1036 (SOT-23) and 2SA1036-Q (SOT-23) is the SMD version of the KTC9012I transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTC9012I with the 2N4403, 2SA708, BC527, BC527-16, BC527-25, BCX79, KN2907, KN2907A, KSA708, KSP2907A, KSP55, KSP8598, KTC8550, KTC8550D, KTN2907, KTN2907A, MPS2907, MPS2907A, MPS2907AG, MPS2907G, MPS4354, MPS4355, MPS6534, MPS6535, MPS6652, MPS6652G, MPS750, MPS750G, MPS751, MPS751G, MPS8598, MPS8598G, MPSA55, MPSA55G, MPSW51, MPSW51A, MPSW51AG, MPSW51G, MPSW55, MPSW55G, P2N2907A, P2N2907AG, PN200, PN2905, PN2905A, PN2907, PN2907A, PN4354, PN4355, ZTX549, ZTX550, ZTX949 or ZTX951.
