Here is an image showing the pin diagram of this transistor.The 2SA985-R transistor can have a current gain of 60 to 120. The gain of the 2SA985 will be in the range from 60 to 320, for the 2SA985-P it will be in the range from 160 to 320, for the 2SA985-Q it will be in the range from 100 to 200, for the 2SA985Q it will be in the range from 85 to 170, for the 2SA985R it will be in the range from 120 to 240, for the 2SA985S it will be in the range from 170 to 340.Sometimes the "2S" prefix is not marked on the package - the 2SA985-R might only be marked "A985-R".The complementary NPN transistor to the 2SA985-R is the 2SC2275-R.You can replace the 2SA985-R with the 2N6476, 2SA1006, 2SA1006-R, 2SA1006A, 2SA1006A-R, 2SA1011, 2SA1011D, 2SA1077, 2SA1078, 2SA1304, 2SA1667, 2SA1668, 2SA1859, 2SA1859A, 2SA1964, 2SA1964-D, 2SA740, 2SA940, 2SA940A, 2SA985A, 2SA985A-R, 2SB1085, 2SB1085-D, 2SB1085A, 2SB1085A-D, 2SB1186A, 2SB1186A-D, 2SB546, 2SB546A, 2SB546A-L, 2SB547, 2SB630, 2SB630-R, 2SB861, 2SB861B, 2SB940, 2SB940-Q, 2SB940A, 2SB940A-Q, BD942, BD942F, BD956, BDT88, BDT88F, FJP1943, FJPF1943, KSA1304, KSA940, KSB546, MJE15029, MJE15029G, MJE15031, MJE15031G, MJF15031, MJF15031G, NTE292 or NTE398.
