Here is an image showing the pin diagram of this transistor.The KTA1049 transistor can have a current gain of 70 to 240. The gain of the KTA1049O will be in the range from 70 to 140, for the KTA1049Y it will be in the range from 120 to 240.The complementary NPN transistor to the KTA1049 is the KTC2028.The BDP954 (SOT-223) is the SMD version of the KTA1049 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTA1049 with the 2SB1016, 2SB1016A, 2SB1367, 2SB595, 2SB995, BD244C, BD540C, BD544C, BD546C, BD802, BD954, BD956, BDT86, BDT86F, BDT88, BDT88F, KTA1038, KTB1367, MJE15029, MJE15029G, MJE15031, MJE15031G, MJF15031 or MJF15031G.
