The 2SC2271-C 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 2SC2271-C transistor can have a current gain of 40 to 80. The gain of the 2SC2271 will be in the range from 40 to 200, for the 2SC2271-D it will be in the range from 60 to 120, for the 2SC2271-E it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SC2271-C might only be marked "C2271-C".The 2SC4497 (SOT-23), 2SC4497-R (SOT-23) and PMBTA42 (SOT-23) is the SMD version of the 2SC2271-C transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2271-C with the 2N6517C, 2SC2482, 2SC2551, 2SC2551-R, 2SC3468, 2SC3468-C, KSC1506, KSC1506-R, KSC2330 or KSC2330R.
