Here is an image showing the pin diagram of this transistor.The 2SC1398-P transistor can have a current gain of 50 to 100. The gain of the 2SC1398 will be in the range from 50 to 220, for the 2SC1398-Q it will be in the range from 80 to 160, 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-P might only be marked "C1398-P".The complementary PNP transistor to the 2SC1398-P is the 2SA748-P.The BSR40 (SOT-89) and FMMT451 (SOT-23) is the SMD version of the 2SC1398-P transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1398-P with the 2N5293, 2N5294, 2N5492, 2N5496, 2N6122, 2N6130, 2N6131, 2N6290, 2N6290G, 2N6291, 2N6292, 2N6292G, 2N6293, 2N6473, 2N6487, 2N6487G, 2N6488, 2N6488G, 2SC1061, 2SC1398A, 2SC1398A-P, 2SC1418, 2SC1419, 2SC1826, 2SC1985, 2SC1986, 2SC2075, 2SC2078, 2SC2233, 2SC2331, 2SC2334, 2SC3179, 2SC3851, 2SC3851A, 2SC4511, 2SC4511-O, 2SC4512, 2SC4512-O, 2SC789, 2SD1265, 2SD1265-P, 2SD1265A, 2SD1265A-P, 2SD1267, 2SD1267A, 2SD1274, 2SD1274A, 2SD1274B, 2SD1355, 2SD1356, 2SD1407, 2SD1407A, 2SD1408, 2SD1568, 2SD1588, 2SD2059, 2SD2060, 2SD234, 2SD288, 2SD313, 2SD330, 2SD362, 2SD389, 2SD389-P, 2SD389A, 2SD389A-P, 2SD525, 2SD526, 2SD568, 2SD569, 2SD613, 2SD743, 2SD743A, 2SD812, 2SD823, 2SD856, 2SD856A, 2SD857, 2SD857A, BD203, BD239A, BD239B, BD239C, BD241A, BD241B, BD241C, BD243A, BD243B, BD243C, BD303, BD535, BD535K, BD537, BD537K, BD539A, BD539B, BD539C, BD707, BD709, BD711, BD743A, BD743B, BD743C, BD797, BD799, BD801, BD807, BD809, BD907, BD909, BD911, BD935, BD935F, BD937, BD937F, BD939, BD939F, BD949, BD951, BD953, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDT91, BDT91F, BDT93, BDT93F, BDT95, BDT95F, BDX77, KSC2334, KSD1408, KSD1588, KSD288, KSD362, KSD526, KSD568, KSD569, KTC1003, KTD2059, KTD2060, MJE2801T, MJE3055T, MJE3055TG, MJF3055, MJF3055G, NTE152 or NTE196.
