Here is an image showing the pin diagram of this transistor.The 2SD1264-Q transistor can have a current gain of 60 to 140. The gain of the 2SD1264 will be in the range from 60 to 240, for the 2SD1264-P it will be in the range from 100 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SD1264-Q might only be marked "D1264-Q".The complementary PNP transistor to the 2SD1264-Q is the 2SB940-Q.You can replace the 2SD1264-Q with the 2SC4381, 2SC4382, 2SC4883, 2SC4883A, 2SD1138, 2SD1264A, 2SD1264A-Q, 2SD401, 2SD401A, 2SD402, 2SD610, 2SD772, 2SD772A, 2SD772B, 2SD792, 2SD792A, 2SD792B, FJP5200, FJPF5200, MJE15030, MJE15030G, MJE15032, MJE15032G, MJF15030, MJF15030G, TIP41F or TIP42F.
