Here is an image showing the pin diagram of this transistor.The 2SA1317 transistor can have a current gain of 100 to 560. The gain of the 2SA1317-R will be in the range from 100 to 200, for the 2SA1317-S it will be in the range from 140 to 280, for the 2SA1317-T it will be in the range from 200 to 400, for the 2SA1317-U it will be in the range from 280 to 560.Sometimes the "2S" prefix is not marked on the package - the 2SA1317 might only be marked "A1317".The complementary NPN transistor to the 2SA1317 is the 2SC3330.The 2SA812 (SOT-23), FJX733 (SOT-323) and KSA812 (SOT-23) is the SMD version of the 2SA1317 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1317 with the 2SA1318, 2SA1391, 2SA1392, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SB1229, 2SB560, 2SB892 or 2SB985.
