The S9012I 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 S9012I transistor can have a current gain of 190 to 300. The gain of the S9012 will be in the range from 64 to 300, for the S9012D it will be in the range from 64 to 91, for the S9012E it will be in the range from 78 to 112, for the S9012F it will be in the range from 96 to 135, for the S9012G it will be in the range from 112 to 166, for the S9012H it will be in the range from 144 to 202.The complementary NPN transistor to the S9012I is the S9013I.You can replace the S9012I with the 2N4403, 2SB564A, BCX79, KN2907, KSB564A, KTC8550, KTC8550D, KTN2907, M8550, M8550-D, MPS2907, MPS2907G, MPS3702, MPS6535, MPS6651, MPS6651G, MPS6652, MPS6652G, MPS750, MPS750G, MPS8550, MPS8550D, MPSW51, MPSW51A, MPSW51AG, MPSW51G, NTE193, PN200, PN2905, PN2907, S8550, S8550D, SS8550, SS8550D, ZTX549, ZTX550 or ZTX949.
