Here is an image showing the pin diagram of this transistor.The KSC2690-Y transistor can have a current gain of 160 to 320. The gain of the KSC2690 will be in the range from 60 to 320, for the KSC2690-O it will be in the range from 100 to 200, for the KSC2690-R it will be in the range from 60 to 120.The complementary PNP transistor to the KSC2690-Y is the KSA1220-Y.The FMMT624 (SOT-23), FMMT625 (SOT-23) and FZT694B (SOT-223) is the SMD version of the KSC2690-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KSC2690-Y with the 2SC2481, 2SC2481-Y, 2SC2690, 2SC2690-P, 2SC2690A, 2SC2690A-P, 2SC3117, 2SC3902, 2SD669, 2SD669-D, KSC2690A, KSC2690A-Y, KTC2803 or KTC2803-GR.
