Here is an image showing the pin diagram of this transistor.The 2SC1625 transistor can have a current gain of 70 to 240. The gain of the 2SC1625-O will be in the range from 70 to 140, for the 2SC1625-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC1625 might only be marked "C1625".The complementary PNP transistor to the 2SC1625 is the 2SA815.The FMMT625 (SOT-23) is the SMD version of the 2SC1625 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1625 with the 2SC1913, 2SC1913A, 2SC2238, 2SC2238A, 2SC2238B, 2SC2275, 2SC2275A, 2SC2336, 2SC2336A, 2SC2528, 2SC3298, 2SC3298A, 2SC3298B, 2SC3944, 2SC3944A, 2SC4381, 2SC4382, 2SC4883, 2SC4883A, 2SD1138, 2SD1264, 2SD1264A, 2SD1562, 2SD363, 2SD401, 2SD402, 2SD772, 2SD772A, 2SD792, 2SD792A, BD539D, BD941, BD941F, BD955, BDT87, BDT87F, KSD363, KTC2238, KTC2238A, KTC4370, KTC4370A, KTD2061, MJE15028, MJE15028G, MJE15030, MJE15030G, MJF15030, MJF15030G, TIP41D, TIP41E, TIP41F, TIP42D, TIP42E or TIP42F.
