Here is an image showing the pin diagram of this transistor.The KSC1507 transistor can have a current gain of 40 to 240. The gain of the KSC1507-O will be in the range from 70 to 140, for the KSC1507-R it will be in the range from 40 to 80, for the KSC1507-Y it will be in the range from 120 to 240.The FMMTA42 (SOT-23) and PMBTA42 (SOT-23) is the SMD version of the KSC1507 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSC1507 with the 2SC2898, 2SC3310, 2SC3794, 2SC3794A, 2SC3795, 2SC3795A, 2SC3868, 2SC3946, 2SC4242, 2SC5241, 2SD1263A, BUX84, BUX85, MJE13070, MJE13071, MJE16002 or MJE16004.
