Here is an image showing the pin diagram of this transistor.The 2SD1412-Y transistor can have a current gain of 120 to 240. The gain of the 2SD1412 will be in the range from 70 to 240, for the 2SD1412-O it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SD1412-Y might only be marked "D1412-Y".The complementary PNP transistor to the 2SD1412-Y is the 2SB1019-Y.You can replace the 2SD1412-Y with the 2SC2334, 2SC2334K, 2SC3254, 2SC3255, 2SC3345, 2SC3345-Y, 2SC3346, 2SC3346-Y, 2SC3709, 2SC3709-Y, 2SC3709A, 2SC3709A-Y, 2SC3710, 2SC3710-Y, 2SC3710A, 2SC3710A-Y, 2SC3747, 2SC3748, 2SC4550, 2SC4551, 2SC4552, 2SD1061, 2SD1062, 2SD1271, 2SD1362, 2SD1362-Y, 2SD1363, 2SD1363-Y, 2SD1411, 2SD1411-Y, 2SD1411A, 2SD1411A-Y, 2SD1668, 2SD1669, 2SD553, 2SD553-Y, 2SD866, 2SD866A, BD203, BD303, BD535, BD537, BD543A, BD543B, BD543C, BD545A, BD545B, BD545C, BD797, BD799, BD801, BD807, BD809, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDX77, D44H11, D44H11FP, D44H8, KSC2334, KSC2334Y or TTC3710B.
