Here is an image showing the pin diagram of this transistor.The KTC2028Y transistor can have a current gain of 120 to 240. The gain of the KTC2028 will be in the range from 70 to 240, for the KTC2028O it will be in the range from 70 to 140.The complementary PNP transistor to the KTC2028Y is the KTA1049O.The BDP953 (SOT-223) is the SMD version of the KTC2028Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTC2028Y with the 2SC2334, 2SC2334K, 2SD1355, 2SD1355-Y, 2SD1407, 2SD1407-Y, 2SD1407A, 2SD1407A-Y, 2SD2059, 2SD2059-Y, 2SD363, 2SD363-Y, 2SD525, 2SD525-Y, 2SD772, 2SD772A, 2SD792, 2SD792A, 2SD866A, BD243C, BD539C, BD539D, BD543C, BD545C, BD801, BD953, BD955, BDT85, BDT85F, BDT87, BDT87F, KSC2334, KSC2334Y, KSD363, KSD363-Y, KTC2018, KTC2018-Y, KTD2059, KTD2059Y, MJE15028, MJE15028G, MJE15030, MJE15030G, MJF15030, MJF15030G, TIP41D, TIP41E, TIP41F, TIP42D, TIP42E or TIP42F.
