Here is an image showing the pin diagram of this transistor.The 2SA1011D transistor can have a current gain of 60 to 120. The gain of the 2SA1011 will be in the range from 60 to 200, for the 2SA1011E it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SA1011D might only be marked "A1011D".The complementary NPN transistor to the 2SA1011D is the 2SC2344D.You can replace the 2SA1011D with the 2SA1006, 2SA1006-R, 2SA1006A, 2SA1006A-R, 2SA1006B, 2SA1006B-R, 2SA1668, 2SA1859A, 2SA1964, 2SA1964-D, 2SB1186A, 2SB1186A-D, 2SB630, 2SB630-R, 2SB940A, 2SB940A-Q, FJP1943, FJPF1943, MJE15033, MJE15033G, MJE5850 or MJE5850G.
