Here is an image showing the pin diagram of this transistor.The 2SC3239-O transistor can have a current gain of 70 to 140. The gain of the 2SC3239 will be in the range from 70 to 240, for the 2SC3239-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC3239-O might only be marked "C3239-O".The complementary PNP transistor to the 2SC3239-O is the 2SA1279-O.You can replace the 2SC3239-O with the 2N6290, 2N6290G, 2N6291, 2N6292, 2N6292G, 2N6293, 2N6487, 2N6487G, 2N6488, 2N6488G, 2SC1985, 2SC1986, 2SC2334, 2SC2334L, 2SC2562, 2SC2562O, 2SC3253, 2SC3253-Q, 2SC3254, 2SC3254-Q, 2SC3255, 2SC3255-Q, 2SC3258, 2SC3258-O, 2SC3299, 2SC3299-O, 2SC3308, 2SC3308-O, 2SC3345, 2SC3345-O, 2SC3346, 2SC3346-O, 2SC3540, 2SC3540-O, 2SC3709, 2SC3709-O, 2SC3709A, 2SC3709A-O, 2SC3710, 2SC3710-O, 2SC3710A, 2SC3710A-O, 2SC3746, 2SC3746-Q, 2SC3747, 2SC3747-Q, 2SC3748, 2SC3748-Q, 2SC4511, 2SC4511-P, 2SC4512, 2SC4512-P, 2SD1060-Q, 2SD1061, 2SD1061-Q, 2SD1062, 2SD1062-Q, 2SD1270, 2SD1271, 2SD1274, 2SD1274A, 2SD1274B, 2SD1355, 2SD1355-O, 2SD1362, 2SD1362-O, 2SD1363, 2SD1363-O, 2SD1407, 2SD1407-O, 2SD1407A, 2SD1407A-O, 2SD1411, 2SD1411-O, 2SD1411A, 2SD1411A-O, 2SD1412, 2SD1412-O, 2SD1588, 2SD1667, 2SD1667-Q, 2SD1668, 2SD1668-Q, 2SD1669, 2SD1669-Q, 2SD2059, 2SD2059-O, 2SD362, 2SD362-O, 2SD525, 2SD525-O, 2SD553, 2SD553-O, 2SD568, 2SD569, 2SD613, 2SD812, 2SD823, 2SD866, 2SD866A, BD203, BD243A, BD243B, BD243C, BD303, BD535, BD537, BD539A, BD539B, BD539C, BD543A, BD543B, BD543C, BD545A, BD545B, BD545C, BD707, BD709, BD711, BD743A, BD743B, BD743C, BD797, BD799, BD801, BD807, BD809, BD907, BD909, BD911, BD949, BD951, BD953, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDT91, BDT91F, BDT93, BDT93F, BDT95, BDT95F, BDX77, D44H11, D44H11FP, D44H8, KSC2334, KSC2334O, KSD1588, KSD362, KSD362-O, KSD568, KSD569, KTC2018, KTC2018-O, KTC2028, KTC2028O, KTD2059, KTD2059O or NTE196.
