Here is an image showing the pin diagram of this transistor.The KTC2026 transistor can have a current gain of 100 to 300. The gain of the KTC2026-GR will be in the range from 150 to 300, for the KTC2026-Y it will be in the range from 100 to 200, for the KTC2026GR it will be in the range from 150 to 300, for the KTC2026Y it will be in the range from 100 to 200.The BDP949 (SOT-223) is the SMD version of the KTC2026 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTC2026 with the 2SC1826, 2SC1985, 2SC1986, 2SC2075, 2SC3179, 2SC3851, 2SC3851A, 2SC4007, 2SC4008, 2SC4550, 2SC4551, 2SC4552, 2SD1134, 2SD1266, 2SD1266A, 2SD1274, 2SD1274A, 2SD1274B, 2SD1354, 2SD1406, 2SD1761, 2SD2012, 2SD2061, 2SD2394, 2SD313, 2SD613, 2SD823, 2SD880, BD203, BD241A, BD241B, BD241C, BD243A, BD243B, BD243C, BD303, BD535, BD537, BD539A, BD539B, BD539C, BD539D, BD543A, BD543B, BD543C, BD545A, BD545B, BD545C, BD797, BD799, BD801, BD807, BD809, BD949, BD951, BD953, BD955, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDT87, BDT87F, BDX77, D44H11, D44H11FP, D44H8, KSD1406, KSD2012, KSD2058, KSD880, KTC2016, KTD1351, MJE15028, MJE15028G, TIP41D or TIP42D.
