The 2SC1317-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 2SC1317-S transistor can have a current gain of 170 to 340. The gain of the 2SC1317 will be in the range from 85 to 340, for the 2SC1317-Q it will be in the range from 85 to 170, for the 2SC1317-R it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC1317-S might only be marked "C1317-S".The complementary PNP transistor to the 2SC1317-S is the 2SA719-S.The 2SC2859 (SOT-23), 2SC4118 (SOT-323), BC818 (SOT-23), BC818-25 (SOT-23), BC818-25W (SOT-323), BC818W (SOT-323), KTC3876 (SOT-23) and KTC3876S (SOT-23) is the SMD version of the 2SC1317-S transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1317-S with the 2N3394, 2SC1318, 2SC1318-S, 2SC1383, 2SC1383-S, 2SC1384, 2SC1384-S, 2SC1959, 2SC2001, 2SC2500, 2SC2500-A, 2SC2500-B, 2SC2500-C, 2SC2500-D, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SC3940, 2SC3940-S, 2SC3940A, 2SC3940A-S, 2SC4208, 2SC4208-S, 2SC4208A, 2SC4208A-S, 2SC4408, 2SC4604, 2SD1207, 2SD1347, 2SD1616, 2SD1835, 2SD471, 2SD545, 2SD592, 2SD592-S, 2SD592A, 2SD592A-S, 2SD789, KSC2500, KSC2500-A, KSC2500-B, KSC2500-C, KSC2500-D, KSC5019, KSD1020, KSD1021, KSD1616 or KSD471AC.
