The KTA1272 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 KTA1272 transistor can have a current gain of 100 to 320. The gain of the KTA1272O will be in the range from 100 to 200, for the KTA1272Y it will be in the range from 160 to 320.The complementary NPN transistor to the KTA1272 is the KTC3204.The 2SA1036 (SOT-23), 2SA1204 (SOT-89), 2SA1588 (SOT-323), 2SA1621 (SOT-23), KTA1298 (SOT-23), KTA1505 (SOT-23), KTA1505S (SOT-23), KTA1664 (SOT-89) and KTC8550S (SOT-23) is the SMD version of the KTA1272 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTA1272 with the 2N4954, 2SA1150, 2SA1271, 2SA1273, 2SA1534A, 2SA684, 2SA928A, 2SA950, 2SA966, 2SB1229, 2SB740, 2SB764, 2SB892, 2SB985, KSA928A, KTA1271, KTA1273, KTA1282, KTB764 or STB1277.
