Here is an image showing the pin diagram of this transistor.The 2SC1212-B transistor can have a current gain of 60 to 120. The gain of the 2SC1212 will be in the range from 60 to 200, for the 2SC1212-C it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SC1212-B might only be marked "C1212-B".The complementary PNP transistor to the 2SC1212-B is the 2SA743-B.The 2SC3444 (SOT-89), 2SC3444-C (SOT-89), 2SC3912 (SOT-23), 2SC3913 (SOT-23), 2SC3914 (SOT-23), 2SC3915 (SOT-23), BCP55 (SOT-223), FMMTA05 (SOT-23) and KST05 (SOT-23) is the SMD version of the 2SC1212-B transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1212-B with the 2N4922, 2N4922G, 2N4923, 2N4923G, 2SC1212A, 2SC1212A-B, 2SC496, 2SD600, 2SD600-D, 2SD794A, 2SD794A-R, BD137, BD137G, BD139, BD139G, BD167, BD169, BD177, BD179, BD189, BD228, BD230, BD235, BD235G, BD237, BD237G, BD377, BD379, BD439, BD439G, BD441, BD441G, BD787, BD787G, BD789, BD791, BDX35, BDX36, BDX37, KSD794A, KSD794A-R, KSE181, KSE182, MJE181, MJE181G, MJE182, MJE182G, MJE223, MJE224, MJE225, MJE240, MJE241, MJE242, MJE243, MJE243G, MJE244, MJE721 or MJE722.
