Here is an image showing the pin diagram of this transistor.The 2SC2231 transistor can have a current gain of 100 to 320. The gain of the 2SC2231-O will be in the range from 100 to 200, for the 2SC2231-Y it will be in the range from 160 to 320.Sometimes the "2S" prefix is not marked on the package - the 2SC2231 might only be marked "C2231".You can replace the 2SC2231 with the 2SC2231A or 2SC2483.
