Here is an image showing the pin diagram of this transistor.The 2SC5197O transistor can have a current gain of 80 to 160. The gain of the 2SC5197 will be in the range from 55 to 160, for the 2SC5197R it will be in the range from 55 to 100.Sometimes the "2S" prefix is not marked on the package - the 2SC5197O might only be marked "C5197O".The complementary PNP transistor to the 2SC5197O is the 2SA1940O.You can replace the 2SC5197O with the 2SC2563, 2SC2563-O, 2SC2579, 2SC2580, 2SC2581, 2SC2706, 2SC2706-O, 2SC2837, 2SC3181, 2SC3181-O, 2SC3181N, 2SC3181N-O, 2SC3182, 2SC3182-O, 2SC3280, 2SC3280O, 2SC3281, 2SC3281O, 2SC3284, 2SC3519, 2SC3519A, 2SC3519A-O, 2SC3519A-P, 2SC3519A-Y, 2SC3854, 2SC3855, 2SC3856, 2SC3907, 2SC4278, 2SC4467, 2SC4468, 2SC4652, 2SC4689, 2SC4689-O, 2SC4690, 2SC4690-O, 2SC5198, 2SC5198O, 2SC5199, 2SC5199O, 2SC5200, 2SC5200N, 2SC5200O, 2SC5358, 2SC5358-O, 2SC5774, 2SC5775, 2SC5948, 2SC5948-O, 2SC5949, 2SC5949-O, 2SC6011, 2SC6011A, 2SC6011A-O, 2SC6011A-P, 2SC6011A-Y, 2SD1046, 2SD1047, 2SD1148, 2SD1148-O, 2SD1289, 2SD1717, 2SD1717-S, 2SD1718, 2SD1718-S, 2SD2052, 2SD2052-S, 2SD2053, 2SD2155, 2SD2155-O, 2SD712, 2SD712O, 2SD998, 2SD998-O, FJA4310, KTC5200, KTC5200A, KTC5200AO, KTC5200O, KTC5242, KTC5242A, KTC5242AO, KTC5242O, KTD1047, KTD1047B, KTD718, KTD718-O, KTD718B, KTD718B-O, KTD998, KTD998-O, MJW3281A, MJW3281AG, NTE2328, TTC0001, TTC0002 or TTC5200.
