Here is an image showing the pin diagram of this transistor.The 2SA885S transistor can have a current gain of 170 to 340. The gain of the 2SA885 will be in the range from 85 to 340, for the 2SA885Q it will be in the range from 85 to 170, for the 2SA885R it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SA885S might only be marked "A885S".The complementary NPN transistor to the 2SA885S is the 2SC1846S.You can replace the 2SA885S with the 2SA985S, 2SB1142, 2SB1143, 2SB1165, 2SB1166, 2SB731, 2SB986, BD132, BD166, BD168, BD188, BD190, BD234, BD234G, BD236, BD236G, BD376, BD376-25, BD378, BD378-25, MJE232, MJE235, MJE371, MJE371G, MJE710 or MJE711.
