Here is an image showing the pin diagram of this transistor.Sometimes the "2S" prefix is not marked on the package - the 2SC2073 might only be marked "C2073".The complementary PNP transistor to the 2SC2073 is the 2SA940.The FMMT625 (SOT-23) is the SMD version of the 2SC2073 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2073 with the 2SC1448, 2SC2073A, 2SC3296, 2SD401, 2SD401A, 2SD402, 2SD610, 2SD772, 2SD772A, 2SD772B, 2SD792, 2SD792A, 2SD792B, KSC2073, KSC3296, MJE15030, MJE15030G, MJF15030, MJF15030G, TIP41F or TIP42F.
