Here is an image showing the pin diagram of this transistor.The 2SC2751-Y transistor can have a current gain of 40 to 80. The gain of the 2SC2751 will be in the range from 15 to 80, for the 2SC2751-N it will be in the range from 15 to 30, for the 2SC2751-O it will be in the range from 30 to 60, for the 2SC2751-R it will be in the range from 20 to 40.Sometimes the "2S" prefix is not marked on the package - the 2SC2751-Y might only be marked "C2751-Y".You can replace the 2SC2751-Y with the 2SC3320.
