Here is an image showing the pin diagram of this transistor.The 2SA1010L transistor can have a current gain of 60 to 120. The gain of the 2SA1010 will be in the range from 40 to 200, for the 2SA1010K it will be in the range from 100 to 200, for the 2SA1010M it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SA1010L might only be marked "A1010L".The complementary NPN transistor to the 2SA1010L is the 2SC2334L.You can replace the 2SA1010L with the 2SA1077, BD544C, BD546C, BD712, BD744C, BD802, BD912, BDT86, BDT86F, BDT88, BDT88F, BDT96, BDT96F, KSA1010, KSA1010O, MJE15029, MJE15029G, MJE15031, MJE15031G, MJF15031 or MJF15031G.
