Here is an image showing the pin diagram of this transistor.The 2SC2688-K transistor can have a current gain of 160 to 250. The gain of the 2SC2688 will be in the range from 40 to 250, for the 2SC2688-L it will be in the range from 100 to 200, 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-K might only be marked "C2688-K".The FMMTA42 (SOT-23) and PMBTA42 (SOT-23) is the SMD version of the 2SC2688-K transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2688-K with the 2N5656, 2N5656G, 2N5657, 2N5657G, 2SC2899, 2SC4212, BD128, BD129, BUX86, BUX87, KSC2688 or KSC2688-G.
