Here is an image showing the pin diagram of this transistor.The KTC1027-O transistor can have a current gain of 80 to 240. The gain of the KTC1027 will be in the range from 80 to 240, for the KTC1027-Y it will be in the range from 80 to 240.The complementary PNP transistor to the KTC1027-O is the KTA1023-O.The 2SC2881 (SOT-89) and KTC4373 (SOT-89) is the SMD version of the KTC1027-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTC1027-O with the 2SC2235, 2SC2383, 2SC3228, KSC2316, KSC2383 or KTC3228.
