Here is an image showing the pin diagram of this transistor.The 2SC1212 transistor can have a current gain of 60 to 200. The gain of the 2SC1212-B will be in the range from 60 to 120, 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 might only be marked "C1212".The complementary PNP transistor to the 2SC1212 is the 2SA743.The 2SC3444 (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 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1212 with the 2SC1212A, 2SC496, 2SD600, 2SD794A, BD137, BD137G, BD139, BD139G, BD167, BD169, BD177, BD179, BD189, BD228, BD230, BD235, BD235G, BD237, BD237G, BD377, BD379, BD787, BD787G, BD789, BD791, BDX35, BDX36, BDX37, KSD794A, KSE181, KSE182, MJE181, MJE181G, MJE182, MJE182G, MJE223, MJE225, MJE240, MJE242, MJE244, MJE721 or MJE722.
