The KTC3266 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 KTC3266 transistor can have a current gain of 120 to 400. The gain of the KTC3266-GR will be in the range from 200 to 400, for the KTC3266-Y it will be in the range from 120 to 240.The complementary PNP transistor to the KTC3266 is the KTA1296.The BCX68 (SOT-89) is the SMD version of the KTC3266 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SC3266 is the TO-92 version of the KTC3266.You can replace the KTC3266 with the 2SC3266 or KTD1146.
