The 2SA1127-S is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, collector, and base leads.
Here is an image showing the pin diagram of this transistor.The 2SA1127-S transistor can have a current gain of 260 to 520. The gain of the 2SA1127 will be in the range from 180 to 700, for the 2SA1127-R it will be in the range from 180 to 360, for the 2SA1127-T it will be in the range from 360 to 700.Sometimes the "2S" prefix is not marked on the package - the 2SA1127-S might only be marked "A1127-S".The complementary NPN transistor to the 2SA1127-S is the 2SC2634-S.You can replace the 2SA1127-S with the 2SA1025, 2SA1081, 2SA1083, 2SA1084, 2SA1316, 2SA991, 2SB560, 2SB726 or 2SB726-S.
