Here is an image showing the pin diagram of this transistor.The complementary PNP transistor to the BDT29A is the BDT30A.The 2SD1615A (SOT-89), 2SD1615A-GP (SOT-89) and 2SD1615A-GQ (SOT-89) is the SMD version of the BDT29A transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the BDT29A with the 2N6043, 2N6043G, 2N6044, 2N6044G, 2N6045, 2N6045G, 2N6387,
