Here is an image showing the pin diagram of this transistor.The 2SA1010 transistor can have a current gain of 40 to 200. The gain of the 2SA1010K will be in the range from 100 to 200, for the 2SA1010L it will be in the range from 60 to 120, for the 2SA1010M it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SA1010 might only be marked "A1010".The complementary NPN transistor to the 2SA1010 is the 2SC2334.You can replace the 2SA1010 with the BD802, BDT86, BDT86F, BDT88, BDT88F, BDT96, BDT96F, KSA1010, MJE15029, MJE15029G, MJE15031, MJE15031G, MJF15031 or MJF15031G.
