Here is an image showing the pin diagram of this transistor.The KTA1274Y transistor can have a current gain of 120 to 240. The gain of the KTA1274 will be in the range from 70 to 240, for the KTA1274O it will be in the range from 70 to 140.The complementary NPN transistor to the KTA1274Y is the KTC3227Y.The 2SA1202 (SOT-89), 2SA1202-Y (SOT-89), 2SA1620 (SOT-23), 2SA1620-Y (SOT-23), KTA1662 (SOT-89) and KTA1662Y (SOT-89) is the SMD version of the KTA1274Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTA1274Y with the 2N5401C, 2SA1275, 2SA1284, 2SA1315, 2SA1315-Y, 2SA1319, 2SA1450, 2SA817A, 2SA817A-Y, 2SA935, 2SA935-Q, 2SA965, 2SA965-Y, 2SA984K, 2SB560, 2SB647, KSA1013, KSA709C, KSA709CY, KSA916, KSA916Y, KSP8599C, KTA1023, KTA1023-O, KTA1023-Y or KTA1275.
