Here is an image showing the pin diagram of this transistor.The 2SC3422-O transistor can have a current gain of 80 to 160. The gain of the 2SC3422 will be in the range from 80 to 240, for the 2SC3422-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC3422-O might only be marked "C3422-O".The complementary PNP transistor to the 2SC3422-O is the 2SA1359-O.The 2SC2873 (SOT-89) is the SMD version of the 2SC3422-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC3422-O with the 2SD1722, 2SD1723, 2SD794, 2SD794A, BD131, BD175, BD175-10, BD177, BD177-10, BD179, BD179-10, BD179G, BD187, BD189, BD785, BD787, BD787G, BD789, BDX35, BDX36, BDX37, KSD794, KSD794A, KSE180, KSE181, KSE182, MJE180, MJE180G, MJE181, MJE181G, MJE182, MJE182G, MJE220, MJE222, MJE223, MJE225, MJE240, MJE241 or MJE242.
