Here is an image showing the pin diagram of this transistor.The 2SC2331M transistor can have a current gain of 40 to 80. The gain of the 2SC2331 will be in the range from 40 to 200, for the 2SC2331K it will be in the range from 100 to 200, for the 2SC2331L it will be in the range from 60 to 120.Sometimes the "2S" prefix is not marked on the package - the 2SC2331M might only be marked "C2331M".The complementary PNP transistor to the 2SC2331M is the 2SA1008M.You can replace the 2SC2331M with the 2N6473, 2N6474, 2N6477, 2N6478, 2SC2334, 2SC2334M, 2SD1355, 2SD1355-R, 2SD1407, 2SD1407-R, 2SD1407A, 2SD1407A-R, 2SD2059, 2SD2059-R, 2SD363, 2SD363-R, 2SD401, 2SD401-R, 2SD401A, 2SD401A-M, 2SD402, 2SD525, 2SD525-R, 2SD610, 2SD610-S, 2SD743A, 2SD743A-S, 2SD772, 2SD772A, 2SD792, 2SD792A, BD239C, BD241C, BD243C, BD539C, BD539D, BD711, BD743C, BD801, BD911, BD939, BD939F, BD941, BD941F, BD953, BD955, BDT85, BDT85F, BDT87, BDT87F, BDT95, BDT95F, KSC2334, KSC2334R, KSD363, KSD363-R, KTD2059, KTD2059R, MJE15028, MJE15028G, MJE15030, MJE15030G, MJE5180, MJE5181, MJE5182, MJF15030, MJF15030G, NTE291, TIP41D, TIP41E, TIP41F, TIP42D, TIP42E or TIP42F.
