Here is an image showing the pin diagram of this transistor.The 2SC2688-L transistor can have a current gain of 100 to 200. The gain of the 2SC2688 will be in the range from 40 to 250, for the 2SC2688-K it will be in the range from 160 to 250, for the 2SC2688-M it will be in the range from 60 to 120, for the 2SC2688-N it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SC2688-L might only be marked "C2688-L".The FMMTA42 (SOT-23) and PMBTA42 (SOT-23) is the SMD version of the 2SC2688-L transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2688-L with the 2N5656, 2N5656G, 2N5657, 2N5657G, 2SC2899, 2SC4212, BD128, BD129, BD158, BD159, BD410, BUX86, BUX87, KSC2688, KSC2688-Y, KSE340, MJE340, MJE340G, MJE3439 or MJE3439G.
