Here is an image showing the pin diagram of this transistor.The 2SA1124-T transistor can have a current gain of 260 to 450. The gain of the 2SA1124 will be in the range from 130 to 450, for the 2SA1124-R it will be in the range from 130 to 220, for the 2SA1124-S it will be in the range from 185 to 330.Sometimes the "2S" prefix is not marked on the package - the 2SA1124-T might only be marked "A1124-T".You can replace the 2SA1124-T with the 2SA1123, 2SA1123-T, 2SA1285A, 2SA1285A-F, 2SA1376, BF421, BF423 or KTA1279.
