Here is an image showing the pin diagram of this transistor.The 2SD863-D transistor can have a current gain of 60 to 120. The gain of the 2SD863 will be in the range from 60 to 320, for the 2SD863-E it will be in the range from 100 to 200, for the 2SD863-F it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SD863-D might only be marked "D863-D".The complementary PNP transistor to the 2SD863-D is the 2SB764-D.The 2SC3444 (SOT-89), 2SC3444-C (SOT-89), BCP55 (SOT-223), BSR40 (SOT-89), FMMTA05 (SOT-23) and KST05 (SOT-23) is the SMD version of the 2SD863-D transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The KTD863-O is the TO-92 version of the 2SD863-D.You can replace the 2SD863-D with the 2SC3243, 2SD667, 2SD667A, 2SD667AB, 2SD667B, KTD863 or KTD863-O.
