Here is an image showing the pin diagram of this transistor.The 2SA1477-T transistor can have a current gain of 200 to 400. The gain of the 2SA1477 will be in the range from 100 to 400, for the 2SA1477-R it will be in the range from 100 to 200, for the 2SA1477-S it will be in the range from 140 to 280.Sometimes the "2S" prefix is not marked on the package - the 2SA1477-T might only be marked "A1477-T".The complementary NPN transistor to the 2SA1477-T is the 2SC3787-T.You can replace the 2SA1477-T with the 2SA1209, 2SA1209-T, 2SA1210, 2SA1210-T, 2SA1248, 2SA1248-T, 2SA1249, 2SA1249-T, 2SA1507 or 2SA1507-T.
