Here is an image showing the pin diagram of this transistor.Sometimes the "2S" prefix is not marked on the package - the 2SC1986 might only be marked "C1986".The complementary PNP transistor to the 2SC1986 is the 2SA771.The BDP951 (SOT-223) and BDP953 (SOT-223) is the SMD version of the 2SC1986 transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC1986 with the 2N6044, 2N6044G, 2N6045, 2N6045G, 2N6388, 2N6388G, 2N6530, 2N6531, 2N6532, 2N6533, 2SC2316, 2SC2334, 2SC2334K, 2SC2334L, 2SC2334M, 2SC2527, 2SC3346, 2SC3346-O, 2SC3346-Y, 2SC3710, 2SC3710-O, 2SC3710-Y, 2SC3710A, 2SC3710A-O, 2SC3710A-Y, 2SC3834, 2SC4153, 2SC4511, 2SC4511-O, 2SC4511-P, 2SC4511-Y, 2SC4512, 2SC4512-O, 2SC4512-P, 2SC4512-Y, 2SD1196, 2SD1271, 2SD1271-P, 2SD1271-Q, 2SD1271-R, 2SD1277A, 2SD1277A-P, 2SD1277A-Q, 2SD1362, 2SD1362-O, 2SD1362-Y, 2SD1411, 2SD1411-O, 2SD1411-Y, 2SD1411A, 2SD1411A-O, 2SD1411A-Y, 2SD1415, 2SD1415A, 2SD1830, 2SD2495, 2SD2495-O, 2SD2495-P, 2SD2495-Y, 2SD363, 2SD363-O, 2SD363-R, 2SD363-Y, 2SD569, 2SD569-K, 2SD569-L, 2SD569-M, 2SD613, 2SD613-C, 2SD613-D, 2SD613-E, 2SD613-F, 2SD633, 2SD634, 2SD866, 2SD866-P, 2SD866-Q, 2SD866-R, 2SD866A, 2SD866A-P, 2SD866A-Q, 2SD866A-R, BD537, BD537K, BD543B, BD543C, BD545B, BD545C, BD647, BD649, BD651, BD899, BD899A, BD901, BDT63A, BDT63B, BDT63C, BDT65A, BDT65B, BDT65C, BDT83, BDT83F, BDT85, BDT85F, BDT87, BDT87F, BDW23B, BDW23C, BDW41, BDW41G, BDW42, BDW42G, BDW43, BDW63B, BDW63C, BDW63D, BDW73B, BDW73C, BDW73D, BDW93B, BDW93C, BDW93CF, BDX33B, BDX33BG, BDX33C, BDX33CG, BDX33D, BDX53B, BDX53BG, BDX53C, BDX53CG, BDX53D, BDX53E, BDX53F, D44H11, D44H11FP, KSC2334, KSC2334O, KSC2334R, KSC2334Y, KSD363, KSD363-O, KSD363-R, KSD363-Y, KSD569, KSD569-O, KSD569-R, KSD569-Y, MJE15028, MJE15028G, MJE15030, MJE15030G, MJF15030, MJF15030G, MJF6388, MJF6388G, TIP101, TIP101G, TIP102, TIP102G, TIP131, TIP131G, TIP132, TIP132G, TIP141T, TIP142T, TTC3710B or TTD1415B.
