Here is an image showing the pin diagram of this transistor.The 2SC2331K transistor can have a current gain of 100 to 200. The gain of the 2SC2331 will be in the range from 40 to 200, for the 2SC2331L it will be in the range from 60 to 120, for the 2SC2331M it will be in the range from 40 to 80.Sometimes the "2S" prefix is not marked on the package - the 2SC2331K might only be marked "C2331K".The complementary PNP transistor to the 2SC2331K is the 2SA1008K.You can replace the 2SC2331K with the 2SC2334, 2SC2527, 2SC2528, 2SC3834, 2SC4153, 2SC4381, 2SC4382, 2SC4883, 2SC4883A, 2SC5171, 2SD1138, 2SD1138C, 2SD1264, 2SD1264-P, 2SD1264A, 2SD1264A-P, 2SD1355, 2SD1407, 2SD1407A, 2SD1763, 2SD1763-E, 2SD2059, 2SD363, 2SD401, 2SD401A, 2SD401A-K, 2SD402, 2SD525, 2SD610, 2SD610-Q, 2SD743A, 2SD743A-Q, 2SD772, 2SD772A, 2SD792, 2SD792A, 2SD866A, BD239C, BD241C, BD243C, BD539C, BD539D, BD543C, BD545C, BD801, BD939, BD939F, BD941, BD941F, BD953, BD955, BDT85, BDT85F, BDT87, BDT87F, BDT95, BDT95F, KSC2334, KSD363, KTC2018, KTC2028, KTD2059, KTD2061, MJE15028, MJE15028G, MJE15030, MJE15030G, MJF15030, MJF15030G, NTE375, TIP41D, TIP41E, TIP41F, TIP42D, TIP42E or TIP42F.
