Here is an image showing the pin diagram of this transistor.Sometimes the "2S" prefix is not marked on the package - the 2SC3179 might only be marked "C3179".The complementary PNP transistor to the 2SC3179 is the 2SA1262.The BDP949 (SOT-223) and FZT692B (SOT-223) is the SMD version of the 2SC3179 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC3179 with the 2N6043, 2N6043G, 2N6044, 2N6044G, 2N6045, 2N6045G, 2N6387, 2N6387G, 2N6388, 2N6388G, 2N6530, 2N6531, 2N6532, 2N6533, 2SC1826, 2SC1827, 2SC1985, 2SC1986, 2SC2315, 2SC2316, 2SC2334, 2SC2334K, 2SC2334L, 2SC2334M, 2SC2527, 2SC3145, 2SC3253, 2SC3253-Q, 2SC3253-R, 2SC3253-S, 2SC3254, 2SC3254-Q, 2SC3254-R, 2SC3254-S, 2SC3255, 2SC3255-Q, 2SC3255-R, 2SC3255-S, 2SC3258, 2SC3258-O, 2SC3258-Y, 2SC3308, 2SC3308-O, 2SC3308-Y, 2SC3346, 2SC3346-O, 2SC3346-Y, 2SC3540, 2SC3540-O, 2SC3540-Y, 2SC3710, 2SC3710-O, 2SC3710-Y, 2SC3710A, 2SC3710A-O, 2SC3710A-Y, 2SC3746, 2SC3746-Q, 2SC3746-R, 2SC3746-S, 2SC3747, 2SC3747-Q, 2SC3747-R, 2SC3747-S, 2SC3748, 2SC3748-Q, 2SC3748-R, 2SC3748-S, 2SC3834, 2SC3851, 2SC3851A, 2SC4007, 2SC4007-E, 2SC4007-F, 2SC4007-G, 2SC4008, 2SC4008-E, 2SC4008-F, 2SC4008-G, 2SC4153, 2SC4511, 2SC4511-O, 2SC4511-P, 2SC4511-Y, 2SC4512, 2SC4512-O, 2SC4512-P, 2SC4512-Y, 2SC4550, 2SC4550-K, 2SC4550-L, 2SC4550-M, 2SC4551, 2SC4551-K, 2SC4551-L, 2SC4551-M, 2SC4552, 2SC4552-K, 2SC4552-L, 2SC4552-M, 2SC789, 2SC789-O, 2SC789-R, 2SC789-Y, 2SD1134, 2SD1134-B, 2SD1134-C, 2SD1134-D, 2SD1190, 2SD1191, 2SD1192, 2SD1195, 2SD1196, 2SD1265-O, 2SD1265-P, 2SD1265A-O, 2SD1265A-P, 2SD1267, 2SD1267-P, 2SD1267-Q, 2SD1267-R, 2SD1267A, 2SD1267A-P, 2SD1267A-Q, 2SD1267A-R, 2SD1269, 2SD1269-P, 2SD1269-Q, 2SD1269-R, 2SD1270, 2SD1270-P, 2SD1270-Q, 2SD1270-R, 2SD1271, 2SD1271-P, 2SD1271-Q, 2SD1271-R, 2SD1276, 2SD1276-P, 2SD1276-Q, 2SD1276A, 2SD1276A-P, 2SD1276A-Q, 2SD1277, 2SD1277-P, 2SD1277-Q, 2SD1277A, 2SD1277A-P, 2SD1277A-Q, 2SD1355, 2SD1355-O, 2SD1355-R, 2SD1355-Y, 2SD1356, 2SD1356-O, 2SD1356-R, 2SD1356-Y, 2SD1362, 2SD1362-O, 2SD1362-Y, 2SD1407, 2SD1407-O, 2SD1407-R, 2SD1407-Y, 2SD1407A, 2SD1407A-O, 2SD1407A-R, 2SD1407A-Y, 2SD1408, 2SD1408-O, 2SD1408-R, 2SD1408-Y, 2SD1411, 2SD1411-O, 2SD1411-Y, 2SD1411A, 2SD1411A-O, 2SD1411A-Y, 2SD1414, 2SD1415, 2SD1415A, 2SD1568, 2SD1568-K, 2SD1568-L, 2SD1568-M, 2SD1588, 2SD1588-K, 2SD1588-L, 2SD1588-M, 2SD1825, 2SD1826, 2SD1827, 2SD1829, 2SD1830, 2SD1891, 2SD1891-P, 2SD1891-Q, 2SD1892, 2SD1892-P, 2SD1892-Q, 2SD2059, 2SD2059-O, 2SD2059-R, 2SD2059-Y, 2SD2060, 2SD2060-O, 2SD2060-R, 2SD2060-Y, 2SD2241, 2SD2495, 2SD2495-O, 2SD2495-P, 2SD2495-Y, 2SD362-O, 2SD362-R, 2SD363, 2SD363-O, 2SD363-R, 2SD363-Y, 2SD389-O, 2SD389-P, 2SD389A-O, 2SD389A-P, 2SD476A, 2SD476A-B, 2SD476A-C, 2SD525, 2SD525-O, 2SD525-R, 2SD525-Y, 2SD526, 2SD526-O, 2SD526-R, 2SD526-Y, 2SD560, 2SD560-KB, 2SD560-LB, 2SD560-MB, 2SD568, 2SD568-K, 2SD568-L, 2SD568-M, 2SD569, 2SD569-K, 2SD569-L, 2SD569-M, 2SD613, 2SD613-C, 2SD613-D, 2SD613-E, 2SD613-F, 2SD633, 2SD634, 2SD635, 2SD743, 2SD743-Q, 2SD743-R, 2SD743-S, 2SD743A, 2SD743A-Q, 2SD743A-R, 2SD743A-S, 2SD812, 2SD812-P, 2SD812-Q, 2SD812-R, 2SD837, 2SD837-P, 2SD837-Q, 2SD837-R, 2SD837A, 2SD837A-P, 2SD837A-Q, 2SD837A-R, 2SD857, 2SD857-P, 2SD857-Q, 2SD857-R, 2SD857A, 2SD857A-P, 2SD857A-Q, 2SD857A-R, 2SD866, 2SD866-P, 2SD866-Q, 2SD866-R, 2SD866A, 2SD866A-P, 2SD866A-Q, 2SD866A-R, BD535, BD535K, BD537, BD537K, BD539A, BD539B, BD539C, BD539D, BD543A, BD543B, BD543C, BD545A, BD545B, BD545C, BD645, BD647, BD649, BD651, BD897, BD897A, BD899, BD899A, BD901, BD949, BD951, BD953, BD955, BDT61, BDT61A, BDT61B, BDT61C, BDT63, BDT63A, BDT63B, BDT63C, BDT65, BDT65A, BDT65B, BDT65C, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDT87, BDT87F, BDW23A, BDW23B, BDW23C, BDW40, BDW41, BDW41G, BDW42, BDW42G, BDW43, BDW53A, BDW53B, BDW53C, BDW53D, BDW63A, BDW63B, BDW63C, BDW63D, BDW73A, BDW73B, BDW73C, BDW73D, BDW93A, BDW93B, BDW93C, BDW93CF, BDX33A, BDX33B, BDX33BG, BDX33C, BDX33CG, BDX33D, BDX53A, BDX53B, BDX53BG, BDX53C, BDX53CG, BDX53D, D44H11, D44H11FP, D44H8, KSB601, KSB601-O, KSB601-R, KSB601-Y, KSC2334, KSC2334O, KSC2334R, KSC2334Y, KSD1408, KSD1408-O, KSD1408-R, KSD1408-Y, KSD1588, KSD1588-O, KSD1588-R, KSD1588-Y, KSD362-O, KSD362-R, KSD363, KSD363-O, KSD363-R, KSD363-Y, KSD526, KSD526-O, KSD526-R, KSD526-Y, KSD560, KSD560-O, KSD560-R, KSD560-Y, KSD568, KSD568-O, KSD568-R, KSD568-Y, KSD569, KSD569-O, KSD569-R, KSD569-Y, KTC2018, KTC2018-O, KTC2018-Y, KTC2027, KTC2027-O, KTC2027-Y, KTC2028, KTC2028O, KTC2028Y, KTD2059, KTD2059O, KTD2059R, KTD2059Y, KTD2060, KTD2060O, KTD2060R, KTD2060Y, MJE15028, MJE15028G, MJE800T, MJE801T, MJE802T, MJE803T, MJF122, MJF122G, MJF6388, MJF6388G, NTE152, TIP100, TIP100G, TIP101, TIP101G, TIP102, TIP102G, TIP120, TIP120G, TIP121, TIP121G, TIP122, TIP122G, TIP130, TIP130G, TIP131, TIP131G, TIP132, TIP132G, TIP140T, TIP141T, TIP142T, TTC3710B or TTD1415B.
