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