Here is an image showing the pin diagram of this transistor.The 2SD1046 transistor can have a current gain of 60 to 200. The gain of the 2SD1046-D will be in the range from 60 to 120, for the 2SD1046-E it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SD1046 might only be marked "D1046".The complementary PNP transistor to the 2SD1046 is the 2SB816.You can replace the 2SD1046 with the 2SC2563, 2SC2579, 2SC2580, 2SC2581, 2SC2706, 2SC4278, 2SC4652, 2SD1047, 2SD1289, 2SD1717, 2SD1718, 2SD2052, 2SD2053, KTD1047, KTD1047B, MJW3281A or MJW3281AG.
