Here is an image showing the pin diagram of this transistor.The 2SC3299 transistor can have a current gain of 70 to 240. The gain of the 2SC3299-O will be in the range from 70 to 140, for the 2SC3299-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC3299 might only be marked "C3299".The complementary PNP transistor to the 2SC3299 is the 2SA1307.You can replace the 2SC3299 with the 2SC1985, 2SC1986, 2SC2334, 2SC2562, 2SC3239, 2SC3253, 2SC3254, 2SC3255, 2SC3258, 2SC3308, 2SC3345, 2SC3346, 2SC3540, 2SC3709, 2SC3709A, 2SC3710, 2SC3710A, 2SC3746, 2SC3747, 2SC3748, 2SD1061, 2SD1062, 2SD1270, 2SD1271, 2SD1274, 2SD1274A, 2SD1274B, 2SD1355, 2SD1362, 2SD1363, 2SD1407, 2SD1407A, 2SD1411, 2SD1411A, 2SD1412, 2SD1667, 2SD1668, 2SD1669, 2SD2059, 2SD525, 2SD553, 2SD613, 2SD823, 2SD866, 2SD866A, BD203, BD243A, BD243B, BD243C, BD303, BD535, BD537, BD539A, BD539B, BD539C, BD543A, BD543B, BD543C, BD545A, BD545B, BD545C, BD797, BD799, BD801, BD807, BD809, BD949, BD951, BD953, BDT81, BDT81F, BDT83, BDT83F, BDT85, BDT85F, BDX77, D44H11, D44H11FP, D44H8, KSC2334, KTC2018, KTC2028 or KTD2059.
