The KTC3203 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 KTC3203 transistor can have a current gain of 100 to 320. The gain of the KTC3203O will be in the range from 100 to 200, for the KTC3203Y it will be in the range from 160 to 320.The complementary PNP transistor to the KTC3203 is the KTA1271.The 2SC2859 (SOT-23), 2SC2883 (SOT-89), 2SC4118 (SOT-323), 2SC4210 (SOT-23), KTC3265 (SOT-23), KTC3876 (SOT-23), KTC3876S (SOT-23), KTC4376 (SOT-89) and KTC8050S (SOT-23) is the SMD version of the KTC3203 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The 2SC3203 is the TO-92 version of the KTC3203.You can replace the KTC3203 with the 2SC1384, 2SC2120, 2SC2236, 2SC2328A, 2SC2710, 2SC3203, 2SC3205, 2SC3940A, 2SD1207, 2SD1347, 2SD1835, 2SD789, 2SD863, KSC2328A, KTC1008, KTC3204, KTC3205, KTC3210 or KTD863.Same transistor is also available in:

• TO-92 package, KTA1271Y: 0.625 watts
