Here is an image showing the pin diagram of this transistor.The 2SC1398-Q transistor can have a current gain of 80 to 160. The gain of the 2SC1398 will be in the range from 50 to 220, for the 2SC1398-P it will be in the range from 50 to 100, for the 2SC1398-R it will be in the range from 120 to 220.Sometimes the "2S" prefix is not marked on the package - the 2SC1398-Q might only be marked "C1398-Q".The complementary PNP transistor to the 2SC1398-Q is the 2SA748-Q.The FMMT451 (SOT-23) is the SMD version of the 2SC1398-Q transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1398-Q with the 2SC1061, 2SC1398A, 2SC1398A-Q, 2SC1418, 2SC1419, 2SC1826, 2SC1827, 2SC1985, 2SC1986, 2SC2075, 2SC2078, 2SC2331, 2SC2334, 2SC2562, 2SC3179, 2SC3239, 2SC3252, 2SC3253, 2SC3254, 2SC3255, 2SC3258, 2SC3299, 2SC3308, 2SC3345, 2SC3346, 2SC3540, 2SC3709, 2SC3709A, 2SC3710, 2SC3710A, 2SC3746, 2SC3747, 2SC3748, 2SC3851, 2SC3851A, 2SC4511, 2SC4512, 2SC4935, 2SC789, 2SD1061, 2SD1062, 2SD1133, 2SD1134, 2SD1265, 2SD1265-O, 2SD1265A, 2SD1265A-O, 2SD1266, 2SD1266A, 2SD1267, 2SD1267A, 2SD1268, 2SD1269, 2SD1270, 2SD1271, 2SD1274, 2SD1274A, 2SD1274B, 2SD1354, 2SD1355, 2SD1356, 2SD1362, 2SD1363, 2SD1406, 2SD1407, 2SD1407A, 2SD1408, 2SD1411, 2SD1411A, 2SD1412, 2SD1568, 2SD1588, 2SD1666, 2SD1667, 2SD1668, 2SD1669, 2SD1761, 2SD1762, 2SD1913, 2SD2058, 2SD2059, 2SD2060, 2SD234, 2SD2374, 2SD2374A, 2SD288, 2SD313, 2SD330, 2SD389, 2SD389-O, 2SD389A, 2SD389A-O, 2SD476, 2SD476A, 2SD525, 2SD526, 2SD553, 2SD568, 2SD569, 2SD613, 2SD743, 2SD743A, 2SD812, 2SD823, 2SD856, 2SD856A, 2SD857, 2SD857A, 2SD866, 2SD866A, 2SD880, BD203, BD239A, BD239B, BD239C, 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, BDT91, BDT91F, BDT93, BDT93F, BDT95, BDT95F, BDX77, D44H11, D44H11FP, D44H8, KSC2334, KSD1406, KSD1408, KSD1588, KSD2058, KSD288, KSD526, KSD568, KSD569, KSD880, KTC2018, KTC2027, KTC2028, KTD1351, KTD2058, KTD2059, KTD2060 or NTE152.
