Here is an image showing the pin diagram of this transistor.The KSC2688-R transistor can have a current gain of 40 to 80. The gain of the KSC2688 will be in the range from 40 to 250, for the KSC2688-G it will be in the range from 160 to 250, for the KSC2688-O it will be in the range from 60 to 120, for the KSC2688-Y it will be in the range from 100 to 200.The 2SC4497 (SOT-23), 2SC4497-R (SOT-23), FMMTA42 (SOT-23) and PMBTA42 (SOT-23) is the SMD version of the KSC2688-R transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSC2688-R with the 2N5656, 2N5656G, 2N5657, 2N5657G, 2SC2688, 2SC2688-N, 2SC2752, 2SC2752K, 2SC2899, 2SC4212, BD128, BD129, BD158, BD159, BD410, KSC2752, KSC2752Y, KSE340, MJE340, MJE340G, MJE3439 or MJE3439G.
