Here is an image showing the pin diagram of this transistor.The 2SC1398 transistor can have a current gain of 50 to 220. The gain of the 2SC1398-P will be in the range from 50 to 100, 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 might only be marked "C1398".The complementary PNP transistor to the 2SC1398 is the 2SA748.You can replace the 2SC1398 with the 2SC1061, 2SC1418, 2SC1419, 2SC1826, 2SC1985, 2SC1986, 2SC2075, 2SC2334, 2SC3179, 2SC3851, 2SC3851A, 2SC789, 2SD1267, 2SD1267A, 2SD1274, 2SD1274A, 2SD1274B, 2SD1355, 2SD1356, 2SD1407, 2SD1407A, 2SD1408, 2SD2059, 2SD2060, 2SD234, 2SD288, 2SD313, 2SD330, 2SD525, 2SD526, 2SD613, 2SD823, 2SD856, 2SD856A, 2SD857, 2SD857A, BD203, BD239A, BD239B, BD239C, BD241A, BD241B, BD241C, BD243A, BD243B, BD243C, BD303, BD535, BD537, BD539A, BD539B, BD539C, BD797, BD799, BD801, BD807, BD809, BD935, BD935F, BD937, BD937F, BD939, BD939F, BD949, BD951, BD953, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDX77, KSC2334, KSD1408, KSD288, KSD526, KTD2059 or KTD2060.
