Here is an image showing the pin diagram of this transistor.The 2SA1516-O transistor can have a current gain of 90 to 180. The gain of the 2SA1516 will be in the range from 55 to 180, for the 2SA1516-R it will be in the range from 55 to 110.Sometimes the "2S" prefix is not marked on the package - the 2SA1516-O might only be marked "A1516-O".The complementary NPN transistor to the 2SA1516-O is the 2SC3907-O.You can replace the 2SA1516-O with the 2SA1386A, 2SA1386A-O, 2SA1386A-P, 2SA1386A-Y, 2SA1492, 2SA1492-Y, 2SA2151, 2SA2151-Y, 2SA2151A, 2SA2151A-O, 2SA2151A-P, 2SA2151A-Y, 2SB1163, MJL4302A, MJL4302AG, MJW1302A or MJW1302AG.
