Here is an image showing the pin diagram of this transistor.The 2SC3346-O transistor can have a current gain of 70 to 140. The gain of the 2SC3346 will be in the range from 70 to 240, for the 2SC3346-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC3346-O might only be marked "C3346-O".The complementary PNP transistor to the 2SC3346-O is the 2SA1329-O.You can replace the 2SC3346-O with the 2N6488, 2N6488G, 2SC3710, 2SC3710-O, 2SC3710A, 2SC3710A-O, BD545B, BD545C, BD709, BD711, BD743B, BD743C, BD909, BD911, BDT83, BDT83F, BDT85, BDT85F, BDT87 or BDT87F.
