Here is an image showing the pin diagram of this transistor.The 2SD1268 transistor can have a current gain of 60 to 260. The gain of the 2SD1268-P will be in the range from 130 to 260, for the 2SD1268-Q it will be in the range from 90 to 180, for the 2SD1268-R it will be in the range from 60 to 120.Sometimes the "2S" prefix is not marked on the package - the 2SD1268 might only be marked "D1268".The complementary PNP transistor to the 2SD1268 is the 2SB943.You can replace the 2SD1268 with the 2SC1986, 2SC2075, 2SC3851A, 2SD1269, 2SD1270, 2SD1271, 2SD1274, 2SD1274A, 2SD1274B, 2SD613, 2SD772, 2SD792, 2SD823, 2SD866, 2SD866A, BD241B, BD241C, BD243B, BD243C, BD537, BD539B, BD539C, BD539D, BD543B, BD543C, BD545B, BD545C, BD799, BD801, BD809, BD951, BD953, BD955, BDT83, BDT83F, BDT85, BDT85F, BDT87, BDT87F, BDX77, D44H11, D44H11FP, MJE15028, MJE15028G, MJE15030, MJE15030G, MJF15030, MJF15030G, TIP41D, TIP41E, TIP41F, TIP42D, TIP42E or TIP42F.
