Here is an image showing the pin diagram of this transistor.The KTD2058Y transistor can have a current gain of 100 to 200. The gain of the KTD2058 will be in the range from 60 to 200, for the KTD2058O it will be in the range from 60 to 120.The complementary PNP transistor to the KTD2058Y is the KTB1366Y.The BDP949 (SOT-223) is the SMD version of the KTD2058Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the KTD2058Y with the 2SC1826, 2SC1827, 2SC1985, 2SC1986, 2SC2075, 2SC2078, 2SC2078E, 2SC2334, 2SC2527, 2SC3179, 2SC3252, 2SC3252-R, 2SC3253, 2SC3253-R, 2SC3254, 2SC3254-R, 2SC3255, 2SC3255-R, 2SC3258, 2SC3308, 2SC3346, 2SC3540, 2SC3710, 2SC3710A, 2SC3746, 2SC3746-R, 2SC3747, 2SC3747-R, 2SC3748, 2SC3748-R, 2SC3834, 2SC3851, 2SC3851A, 2SC4007, 2SC4007-E, 2SC4008, 2SC4008-E, 2SC4153, 2SC4550, 2SC4550-M, 2SC4551, 2SC4551-M, 2SC4552, 2SC4552-M, 2SC789, 2SD1134, 2SD1134-C, 2SD1266, 2SD1266A, 2SD1267, 2SD1267A, 2SD1268, 2SD1269, 2SD1270, 2SD1271, 2SD1274, 2SD1274A, 2SD1274B, 2SD1354, 2SD1354-Y, 2SD1355, 2SD1356, 2SD1362, 2SD1406, 2SD1406-Y, 2SD1407, 2SD1407A, 2SD1408, 2SD1411, 2SD1411A, 2SD1568, 2SD1568-K, 2SD1588, 2SD1588-K, 2SD1666, 2SD1666-R, 2SD1761, 2SD1761-E, 2SD1913, 2SD1913R, 2SD2012, 2SD2058, 2SD2058-Y, 2SD2059, 2SD2060, 2SD2061, 2SD2374, 2SD2374A, 2SD2394, 2SD2394-E, 2SD313, 2SD313E, 2SD363, 2SD476A, 2SD476A-C, 2SD525, 2SD526, 2SD568, 2SD568-K, 2SD569, 2SD569-K, 2SD613, 2SD613-E, 2SD743, 2SD743-Q, 2SD743A, 2SD743A-Q, 2SD812, 2SD812-P, 2SD823, 2SD856, 2SD856A, 2SD857, 2SD857A, 2SD866, 2SD866A, 2SD880, 2SD880Y, 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, BD935, BD935F, BD937, BD937F, BD939, BD939F, BD941, BD941F, BD949, BD951, BD953, BD955, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDT87, BDT87F, BDT91, BDT91F, BDT93, BDT93F, BDT95, BDT95F, BDX77, D44H11, D44H11FP, D44H8, KSC2334, KSD1406, KSD1406-Y, KSD1408, KSD1588, KSD1588-Y, KSD2012, KSD2012-Y, KSD2058, KSD2058-Y, KSD363, KSD526, KSD568, KSD568-Y, KSD569, KSD569-Y, KSD880, KSD880-Y, KTC2016, KTC2016-Y, KTC2018, KTC2026, KTC2026-Y, KTC2026Y, KTC2027, KTC2028, KTD1351, KTD1351Y, KTD2059, KTD2060, MJE15028, MJE15028G, NTE152, TIP41D or TIP42D.
