Here is an image showing the pin diagram of this transistor.The 2SA1317-S transistor can have a current gain of 140 to 280. The gain of the 2SA1317 will be in the range from 100 to 560, for the 2SA1317-R it will be in the range from 100 to 200, 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-S might only be marked "A1317-S".The complementary NPN transistor to the 2SA1317-S is the 2SC3330-S.The 2SA1037 (SOT-23), 2SA1037-Q (SOT-23), 2SA812 (SOT-23), 2SA812-M5 (SOT-23), FJX733 (SOT-323), KSA812 (SOT-23) and KSA812-Y (SOT-23) is the SMD version of the 2SA1317-S transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SA1317-S with the 2SA1283, 2SA1284, 2SA1318, 2SA1318-S, 2SA1391, 2SA1391-S, 2SA1392, 2SA1392-S, 2SA1450, 2SA1450-S, 2SA1522, 2SA1523, 2SA1524, 2SA1525, 2SA1526, 2SA1527, 2SA1528, 2SA1529, 2SA1534A, 2SA1619A, 2SA1680, 2SA1761, 2SA684, 2SA720, 2SA935, 2SA953, 2SA954, 2SA984, 2SA984K, 2SA993, 2SB1116, 2SB1116A, 2SB1229, 2SB1229-S, 2SB560, 2SB647, 2SB740, 2SB764, 2SB892, 2SB892-S, 2SB985, 2SB985S, BC212, BC212A, KSA708C, KSB1116, KSB1116A, KSB1116S, KSP2907AC, KSP8598C, KSP8599C or KTB764.
