Here is an image showing the pin diagram of this transistor.The KTA1276Y transistor can have a current gain of 120 to 240. The gain of the KTA1276 will be in the range from 70 to 240, for the KTA1276O it will be in the range from 70 to 140.The complementary NPN transistor to the KTA1276Y is the KTC3230Y.The 2SA1203 (SOT-89) and KTA1663 (SOT-89) is the SMD version of the KTA1276Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTA1276Y with the 2SA1012, 2SA1012Y, 2SA1262, 2SA1279, 2SA1279-Y, 2SA1288, 2SA1289, 2SA1290, 2SA1291, 2SA1305, 2SA1305-Y, 2SA1307, 2SA1307-Y, 2SA1328, 2SA1328-Y, 2SA1451, 2SA1451-Y, 2SA1451A, 2SA1451A-Y, 2SA1469, 2SA1470, 2SA1471, 2SA1488, 2SA1742, 2SA1743, 2SA1744, 2SA1869, 2SA1869Y, 2SA1931, 2SA473, 2SA473Y, 2SA489, 2SA489-Y, 2SA490, 2SA490-Y, 2SA614, 2SA614Y, 2SA768, 2SA770, 2SB1019, 2SB1019-Y, 2SB1133, 2SB1134, 2SB1135, 2SB1136, 2SB1185, 2SB1187, 2SB1274, 2SB1375, 2SB1548, 2SB1548-P, 2SB1565, 2SB1566, 2SB434, 2SB434Y, 2SB435, 2SB435-Y, 2SB507, 2SB553, 2SB553-Y, 2SB761, 2SB761-P, 2SB762, 2SB762-P, 2SB824, 2SB825, 2SB826, 2SB834, 2SB857, 2SB858, 2SB903, 2SB919, 2SB941, 2SB941-P, 2SB942, 2SB942-P, 2SB947A, 2SB948A, 2SB953A, 2SB993, 2SB993-Y, BD202, BD204, BD242, BD242A, BD244, BD244A, BD302, BD304, BD534, BD536, BD540, BD540A, BD544, BD544A, BD546, BD546A, BD736, BD738, BD796, BD798, BD808, BD934, BD934F, BD936, BD936F, BD946, BD948, BD950, BDT82, BDT82F, D44C1, D44C2, D44C3, D44C4, D44C5, D44C6, D44C7, D44C8, D44C9, D45C1, D45C2, D45C3, D45C4, D45C5, D45C6, D45C7, D45C8, D45C9, D45H8, KSA473, KSA473Y, KSA614, KSA614Y, KSB1366, KTA1036, KTA1658, KTA1658Y or KTB988.
