Here is an image showing the pin diagram of this transistor.The 2SD1562-D transistor can have a current gain of 60 to 120. The gain of the 2SD1562 will be in the range from 60 to 320, for the 2SD1562-E it will be in the range from 100 to 200, for the 2SD1562-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SD1562-D might only be marked "D1562-D".The complementary PNP transistor to the 2SD1562-D is the 2SB1085-D.The FMMT625 (SOT-23) is the SMD version of the 2SD1562-D transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SD1562-D with the 2N6474, 2N6477, 2N6478, 2SC1448, 2SC2073, 2SC2073A, 2SC2275, 2SC2275-R, 2SC2275A, 2SC2275A-R, 2SC2336, 2SC2336-R, 2SC2336A, 2SC2336A-R, 2SC2344, 2SC2344D, 2SC2527, 2SC2528, 2SC3296, 2SC4381, 2SC4382, 2SC4883, 2SC4883A, 2SC5248, 2SC5248-D, 2SD1138, 2SD1138B, 2SD1264, 2SD1264-Q, 2SD1264A, 2SD1264A-Q, 2SD1562A, 2SD1562A-D, 2SD1763A, 2SD1763A-E, 2SD363, 2SD401, 2SD401A, 2SD401A-L, 2SD402, 2SD610, 2SD610-R, 2SD772, 2SD772A, 2SD792, 2SD792A, BD539D, BD941, BD941F, BD955, BDT87, BDT87F, KSC2073, KSC3296, KSD363, MJE15028, MJE15028G, MJE15030, MJE15030G, MJF15030, MJF15030G, NTE291, TIP41D, TIP41E, TIP41F, TIP42D, TIP42E or TIP42F.
