Here is an image showing the pin diagram of this transistor.The 2SD1047-E transistor can have a current gain of 100 to 200. The gain of the 2SD1047 will be in the range from 60 to 200, for the 2SD1047-D it will be in the range from 60 to 120.Sometimes the "2S" prefix is not marked on the package - the 2SD1047-E might only be marked "D1047-E".The complementary PNP transistor to the 2SD1047-E is the 2SB817-E.You can replace the 2SD1047-E with the 2SD1047C, 2SD1717, 2SD1717-P, 2SD1718, 2SD1718-P, KTD1047, KTD1047-Y, KTD1047B, KTD1047B-Y, MJW3281A or MJW3281AG.
