Here is an image showing the pin diagram of this transistor.The KTA1024 transistor can have a current gain of 70 to 240. The gain of the KTA1024O will be in the range from 70 to 140, for the KTA1024Y it will be in the range from 120 to 240.The complementary NPN transistor to the KTA1024 is the KTC3206.The KTA1660 (SOT-89) is the SMD version of the KTA1024 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTA1024 with the 2N5401C, 2SA1024, 2SA1275, 2SA1370, 2SA1371, 2SA1624, 2SA949, BF421, BF423, HSB1109S, KSA1013, KSA709C, KTA1275 or KTA1279.
