Here is an image showing the pin diagram of this transistor.The 2SC5197 transistor can have a current gain of 55 to 160. The gain of the 2SC5197O will be in the range from 80 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 2SC5197 might only be marked "C5197".The complementary PNP transistor to the 2SC5197 is the 2SA1940.You can replace the 2SC5197 with the 2SC2563, 2SC2579, 2SC2580, 2SC2581, 2SC2706, 2SC2837, 2SC3181, 2SC3181-O, 2SC3181N, 2SC3181N-O, 2SC3182, 2SC3182-O, 2SC3280, 2SC3281, 2SC3284, 2SC3519, 2SC3519A, 2SC3519A-O, 2SC3519A-P, 2SC3519A-Y, 2SC3854, 2SC3855, 2SC3907, 2SC4467, 2SC4468, 2SC4689, 2SC4690, 2SC5198, 2SC5199, 2SC5200, 2SC5200N, 2SC5358, 2SC5948, 2SC5949, 2SC6011, 2SC6011A, 2SC6011A-O, 2SC6011A-P, 2SC6011A-Y, 2SD1148, 2SD2155, 2SD712, 2SD998, FJA4310, KTC5200, KTC5200A, KTC5242, KTC5242A, KTD718, KTD718B, KTD998, MJW3281A, MJW3281AG or NTE2328.
