Here is an image showing the pin diagram of this transistor.The 2SC1212A-B transistor can have a current gain of 60 to 120. The gain of the 2SC1212A will be in the range from 60 to 200, for the 2SC1212A-C it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SC1212A-B might only be marked "C1212A-B".The complementary PNP transistor to the 2SC1212A-B is the 2SA743A-B.The 2SC3438 (SOT-89), 2SC3438-C (SOT-89), BCP56 (SOT-223), BSR42 (SOT-89), FMMTA06 (SOT-23) and KST06 (SOT-23) is the SMD version of the 2SC1212A-B transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1212A-B with the 2N4923, 2N4923G, 2SC2481, 2SC2481-R, 2SC2690, 2SC2690-R, 2SC2690A, 2SC2690A-R, 2SC3621, 2SC3621-R, 2SD600, 2SD600-D, 2SD600K, 2SD600K-D, 2SD669, 2SD669-B, 2SD669A, 2SD669A-B, BD139, BD139G, BD169, BD179, BD230, BD237, BD237G, BD379, BD441, BD441G, BD789, BD791, KSC2690, KSC2690-R, KSC2690A, KSC2690A-R, KSE182, MJE182, MJE182G, MJE240, MJE241, MJE242, MJE243, MJE243G, MJE244 or MJE722.
