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