The KTC2874-A 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 KTC2874-A transistor can have a current gain of 200 to 700. The gain of the KTC2874 will be in the range from 200 to 1200, for the KTC2874-B it will be in the range from 350 to 1200.The 2SC3326 (SOT-23), 2SC3326-A (SOT-23), KTC2875 (SOT-23) and KTC2875-A (SOT-23) is the SMD version of the KTC2874-A transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTC2874-A with the 2N3394, 2SC3242A, 2SC3266 or KTD1146.
