Here is an image showing the pin diagram of this transistor.The 2SC1624-O transistor can have a current gain of 70 to 140. The gain of the 2SC1624 will be in the range from 70 to 240, for the 2SC1624-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC1624-O might only be marked "C1624-O".The complementary PNP transistor to the 2SC1624-O is the 2SA814-O.The 2SC3438 (SOT-89) is the SMD version of the 2SC1624-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1624-O with the 2N6473, 2N6474, 2N6477, 2N6478, 2SC1448, 2SC1625, 2SC1625-O, 2SC1913, 2SC1913A, 2SC2073, 2SC2073A, 2SC2238, 2SC2238A, 2SC2238AO, 2SC2238B, 2SC2238BO, 2SC2238O, 2SC2275, 2SC2275A, 2SC2331, 2SC2334, 2SC2334L, 2SC2336, 2SC2336A, 2SC2344, 2SC2527, 2SC2528, 2SC3296, 2SC3298, 2SC3298-O, 2SC3298A, 2SC3298A-O, 2SC3298B, 2SC3298B-O, 2SC3834, 2SC3944, 2SC3944A, 2SC4153, 2SC4381, 2SC4382, 2SC4883, 2SC4883A, 2SC5248, 2SD1138, 2SD1264, 2SD1264-Q, 2SD1264A, 2SD1264A-Q, 2SD1355, 2SD1355-O, 2SD1407, 2SD1407-O, 2SD1407A, 2SD1407A-O, 2SD1562, 2SD1562A, 2SD1763A, 2SD2059, 2SD2059-O, 2SD363, 2SD363-O, 2SD401, 2SD401-O, 2SD401A, 2SD402, 2SD525, 2SD525-O, 2SD610, 2SD743A, 2SD772, 2SD772A, 2SD792, 2SD792A, 2SD866A, BD239C, BD241C, BD243C, BD539C, BD539D, BD543C, BD545C, BD711, BD743C, BD801, BD911, BD939, BD939F, BD941, BD941F, BD953, BD955, BDT29C, BDT85, BDT85F, BDT87, BDT87F, BDT95, BDT95F, KSC2073, KSC2334, KSC2334O, KSC3296, KSD363, KSD363-O, KTC2018, KTC2018-O, KTC2028, KTC2028O, KTC2238, KTC2238A, KTC2238AO, KTC2238O, KTC4370, KTC4370A, KTC4370AO, KTC4370O, KTD2059, KTD2059O, KTD2061, KTD2061O, MJE15028, MJE15028G, MJE15030, MJE15030G, MJF15030, MJF15030G, NTE291, TIP41D, TIP41E, TIP41F, TIP42D, TIP42E or TIP42F.
