Here is an image showing the pin diagram of this transistor.The 2SC2497 transistor can have a current gain of 80 to 220. The gain of the 2SC2497-R will be in the range from 80 to 160, for the 2SC2497-S it will be in the range from 120 to 220.Sometimes the "2S" prefix is not marked on the package - the 2SC2497 might only be marked "C2497".The complementary PNP transistor to the 2SC2497 is the 2SA1096.You can replace the 2SC2497 with the 2SC2497A, 2SD1722, 2SD1723, 2SD1724, 2SD1725, 2SD794A, BD137, BD137G, BD139, BD139G, BD167, BD169, BD177, BD179, BD189, BD228, BD230, BD235, BD235G, BD237, BD237G, BD377, BD379, BD787, BD787G, BD789, BD791, BDX35, BDX36, BDX37, KSD794A, KSE181, KSE182, KTC2814, MJE181, MJE181G, MJE182, MJE182G, MJE225, MJE242, MJE244, MJE721 or MJE722.
