Here is an image showing the pin diagram of this transistor.Sometimes the "2S" prefix is not marked on the package - the 2SC2073A might only be marked "C2073A".The complementary PNP transistor to the 2SC2073A is the 2SA940A.The FMMT625 (SOT-23) is the SMD version of the 2SC2073A transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2073A with the 2SC1448, 2SC2073, 2SC3296, 2SD401, 2SD401A, 2SD402, 2SD610, 2SD772, 2SD772A, 2SD772B, 2SD792, 2SD792A, 2SD792B, KSC2073, KSC3296, MJE15030, MJE15030G, MJF15030, MJF15030G, TIP41F or TIP42F.
