Here is an image showing the pin diagram of this transistor.The 2SA1141-R transistor can have a current gain of 60 to 120. The gain of the 2SA1141 will be in the range from 60 to 200, for the 2SA1141-Q it will be in the range from 100 to 200.Sometimes the "2S" prefix is not marked on the package - the 2SA1141-R might only be marked "A1141-R".The complementary NPN transistor to the 2SA1141-R is the 2SC2681-R.You can replace the 2SA1141-R with the 2SA1673, 2SA1860, 2SA1909, 2SA1987, 2SB1161, 2SB1161-Q or FJAF4210.
