Here is an image showing the pin diagram of this transistor.The 2SC2590-R transistor can have a current gain of 90 to 220. The gain of the 2SC2590 will be in the range from 90 to 220, for the 2SC2590-Q it will be in the range from 90 to 220.Sometimes the "2S" prefix is not marked on the package - the 2SC2590-R might only be marked "C2590-R".You can replace the 2SC2590-R with the 2SC1565, 2SC1565A, 2SC2481, 2SC2690, 2SC2690A, 2SC2824, 2SC3421, 2SD600K, 2SD669, KSC2690, KSC2690A, KTC2800, MJE344 or MJE344G.
