Here is an image showing the pin diagram of this transistor.The 2SC4935Y transistor can have a current gain of 120 to 240. The gain of the 2SC4935 will be in the range from 70 to 240, for the 2SC4935O it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SC4935Y might only be marked "C4935Y".The complementary PNP transistor to the 2SC4935Y is the 2SA1869Y.The 2SC2873 (SOT-89), 2SC2873-Y (SOT-89), 2SD1623 (SOT-89), 2SD1624 (SOT-89), BDP949 (SOT-223) and FMMT619 (SOT-23) is the SMD version of the 2SC4935Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC4935Y with the 2SC1061, 2SC1826, 2SC1827, 2SC1985, 2SC1986, 2SC2075, 2SC2334, 2SC2334K, 2SC2562, 2SC2562Y, 2SC3179, 2SC3239, 2SC3239-Y, 2SC3252, 2SC3253, 2SC3254, 2SC3255, 2SC3258, 2SC3258-Y, 2SC3299, 2SC3299-Y, 2SC3308, 2SC3308-Y, 2SC3345, 2SC3345-Y, 2SC3346, 2SC3346-Y, 2SC3540, 2SC3540-Y, 2SC3709, 2SC3709-Y, 2SC3709A, 2SC3709A-Y, 2SC3710, 2SC3710-Y, 2SC3710A, 2SC3710A-Y, 2SC3746, 2SC3747, 2SC3748, 2SC3851, 2SC3851A, 2SC4007, 2SC4008, 2SC4550, 2SC4551, 2SC4552, 2SC4881, 2SC789, 2SC789-Y, 2SD1060, 2SD1061, 2SD1062, 2SD1133, 2SD1134, 2SD1266, 2SD1266-P, 2SD1266A, 2SD1266A-P, 2SD1267, 2SD1267-P, 2SD1267A, 2SD1267A-P, 2SD1268, 2SD1269, 2SD1270, 2SD1271, 2SD1274, 2SD1274A, 2SD1274B, 2SD1354, 2SD1355, 2SD1355-Y, 2SD1356, 2SD1356-Y, 2SD1362, 2SD1362-Y, 2SD1363, 2SD1363-Y, 2SD1406, 2SD1407, 2SD1407-Y, 2SD1407A, 2SD1407A-Y, 2SD1408, 2SD1408-Y, 2SD1411, 2SD1411-Y, 2SD1411A, 2SD1411A-Y, 2SD1412, 2SD1412-Y, 2SD1666, 2SD1667, 2SD1668, 2SD1669, 2SD1761, 2SD1762, 2SD1913, 2SD2012, 2SD2059, 2SD2059-Y, 2SD2060, 2SD2060-Y, 2SD2061, 2SD234, 2SD234Y, 2SD2374, 2SD2374-P, 2SD2374A, 2SD2374A-P, 2SD2394, 2SD2395, 2SD288, 2SD288-Y, 2SD313, 2SD525, 2SD525-Y, 2SD526, 2SD526-Y, 2SD553, 2SD553-Y, 2SD613, 2SD823, 2SD856, 2SD856-P, 2SD856A, 2SD856A-P, 2SD857, 2SD857-P, 2SD857A, 2SD857A-P, 2SD866, 2SD866A, 2SD880, BD203, BD241A, BD241B, BD241C, BD243A, BD243B, BD243C, BD303, BD535, BD537, BD539A, BD539B, BD539C, BD543A, BD543B, BD543C, BD545A, BD545B, BD545C, BD797, BD799, BD801, BD807, BD809, BD935, BD935F, BD937, BD937F, BD939, BD939F, BD949, BD951, BD953, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDX77, D44H11, D44H11FP, D44H8, KSC2334, KSC2334Y, KSD1406, KSD1408, KSD1408-Y, KSD2012, KSD2058, KSD288, KSD288-Y, KSD526, KSD526-Y, KSD880, KTC2016, KTC2018, KTC2018-Y, KTC2026, KTC2027, KTC2027-Y, KTC2028, KTC2028Y, KTD1351, KTD2059, KTD2059Y, KTD2060, KTD2060Y or TTC3710B.
