Here is an image showing the pin diagram of this transistor.The 2SA2151A transistor can have a current gain of 50 to 180. The gain of the 2SA2151A-O will be in the range from 50 to 180, for the 2SA2151A-P it will be in the range from 50 to 180, for the 2SA2151A-Y it will be in the range from 50 to 180.Sometimes the "2S" prefix is not marked on the package - the 2SA2151A might only be marked "A2151A".The complementary NPN transistor to the 2SA2151A is the 2SC6011A.You can replace the 2SA2151A with the MJW1302A or MJW1302AG.
