The 2SC3203 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 2SC3203 transistor can have a current gain of 100 to 320. The gain of the 2SC3203 will be in the range from 100 to 320, for the 2SC3203-O it will be in the range from 100 to 200, for the 2SC3203-Y it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SC3203 might only be marked "C3203".The complementary PNP transistor to the 2SC3203 is the 2SA1271.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 2SC3203 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.The KTC3203 is the TO-92 version of the 2SC3203.You can replace the 2SC3203 with the 2SC1384, 2SC2120, 2SC2236, 2SC2328A, 2SC2710, 2SC3205, 2SC3940A, 2SD1207, 2SD1347, 2SD1835, 2SD789, 2SD863, KSC2328A, KTC1008, KTC3203, KTC3204, KTC3205, KTC3210 or KTD863.
