Here is an image showing the pin diagram of this transistor.The 2SC2705Y transistor can have a current gain of 120 to 240. The gain of the 2SC2705 will be in the range from 80 to 240, for the 2SC2705O it will be in the range from 80 to 160.Sometimes the "2S" prefix is not marked on the package - the 2SC2705Y might only be marked "C2705Y".The complementary PNP transistor to the 2SC2705Y is the 2SA1145Y.You can replace the 2SC2705Y with the 2N5551C, 2SC2229, 2SC2229-Y, 2SC2230, 2SC2230-Y, 2SC2230A, 2SC2230A-Y, 2SC2383, 2SC2909, 2SC2910, 2SC3206, 2SC3206-Y, 2SC3228, 2SC3332, 2SC3467, 2SC3468, BF420, BF422, HSD1609S, KSC1506, KSC1506-Y, KSC2310, KSC2310-Y, KSC2330, KSC2330Y, KSC2383, KTC3206, KTC3206Y or KTC3228.
