Here is an image showing the pin diagram of this transistor.The 2SC1398A transistor can have a current gain of 50 to 160. The gain of the 2SC1398A-P will be in the range from 50 to 100, for the 2SC1398A-Q it will be in the range from 80 to 160.Sometimes the "2S" prefix is not marked on the package - the 2SC1398A might only be marked "C1398A".You can replace the 2SC1398A with the 2SC1986, 2SC2075, 2SC2078, 2SC2331, 2SC2334, 2SC3851A, 2SC4511, 2SC4512, 2SC789, 2SD1265A, 2SD1267A, 2SD1274, 2SD1274A, 2SD1274B, 2SD1355, 2SD1356, 2SD1407, 2SD1407A, 2SD1408, 2SD2059, 2SD2060, 2SD363, 2SD389A, 2SD525, 2SD526, 2SD569, 2SD613, 2SD743, 2SD743A, 2SD812, 2SD823, 2SD856A, 2SD857A, BD239B, BD239C, BD241B, BD241C, BD243B, BD243C, BD537, BD539B, BD539C, BD539D, BD799, BD801, BD809, BD937, BD937F, BD939, BD939F, BD941, BD941F, BD951, BD953, BD955, BDT83, BDT83F, BDT85, BDT85F, BDT87, BDT87F, BDT93, BDT93F, BDT95, BDT95F, BDX77, KSC2334, KSD1408, KSD363, KSD526, KSD569, KTD2059, KTD2060, MJE15028, MJE15028G, NTE152, TIP41D, TIP41E, TIP42D or TIP42E.
