The KTA1266 is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, collector, and base leads.
Here is an image showing the pin diagram of this transistor.The KTA1266 transistor can have a current gain of 70 to 400. The gain of the KTA1266GR will be in the range from 200 to 400, for the KTA1266O it will be in the range from 70 to 140, for the KTA1266Y it will be in the range from 120 to 240.The complementary NPN transistor to the KTA1266 is the KTC3198.The 2SA1162 (SOT-23), 2SA1586 (SOT-323), 2SA1832 (SOT-23), FJX733 (SOT-323), KTA1504 (SOT-23) and KTA1504S (SOT-23) is the SMD version of the KTA1266 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SA1266 is the TO-92 version of the KTA1266.You can replace the KTA1266 with the 2SA1015, 2SA1048, 2SA1266, 2SA1267, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SB560, A1015, BC212, KSA1015, KSA708C, KSA733C or KTA1267.
