Here is an image showing the pin diagram of this transistor.The 2SA1007A transistor can have a current gain of 40 to 320. The gain of the 2SA1007A-p will be in the range from 160 to 320, for the 2SA1007A-Q it will be in the range from 100 to 200, for the 2SA1007A-R it will be in the range from 60 to 120, for the 2SA1007A-S it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SA1007A might only be marked "A1007A".You can replace the 2SA1007A with the 2SA908, 2SA909 or 2SB697K.
