Here is an image showing the pin diagram of this transistor.The 2SC2921-Y transistor can have a current gain of 90 to 180. The gain of the 2SC2921 will be in the range from 50 to 180, for the 2SC2921-O it will be in the range from 50 to 100, for the 2SC2921-P it will be in the range from 70 to 140.Sometimes the "2S" prefix is not marked on the package - the 2SC2921-Y might only be marked "C2921-Y".The complementary PNP transistor to the 2SC2921-Y is the 2SA1215-Y.You can replace the 2SC2921-Y with the 2SC2565, 2SC2773, 2SC2773-Y, 2SC2922, 2SC2922-G, 2SC3857, 2SC3857-Y, 2SC3858 or 2SC3858-Y.
