Here is an image showing the pin diagram of this transistor.The 2SD1264A-Q transistor can have a current gain of 60 to 140. The gain of the 2SD1264A will be in the range from 60 to 240, for the 2SD1264A-P it will be in the range from 100 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SD1264A-Q might only be marked "D1264A-Q".The complementary PNP transistor to the 2SD1264A-Q is the 2SB940A-Q.You can replace the 2SD1264A-Q with the 2SC4382, 2SC4883A, 2SD610, 2SD772A, 2SD772B, 2SD792A, 2SD792B, FJP5200, FJPF5200, MJE15032 or MJE15032G.
