Here is an image showing the pin diagram of this transistor.The 2SB1115A-YP transistor can have a current gain of 200 to 400. The gain of the 2SB1115A will be in the range from 135 to 400, for the 2SB1115A-YQ it will be in the range from 135 to 270.Sometimes the "2S" prefix is not marked on the package - the 2SB1115A-YP might only be marked "B1115A-YP".You can replace the 2SB1115A-YP with the 2STF2360.
