Here is an image showing the pin diagram of this transistor.The 2SC3459-L transistor can have a current gain of 10 to 20. The gain of the 2SC3459 will be in the range from 10 to 40, for the 2SC3459-M it will be in the range from 15 to 30, for the 2SC3459-N it will be in the range from 20 to 40.Sometimes the "2S" prefix is not marked on the package - the 2SC3459-L might only be marked "C3459-L".You can replace the 2SC3459-L with the 2SC3153, 2SC3153-K, 2SC3460, 2SC3460-L, 2SC3461, 2SC3461-L, 2SC3552, 2SC3552-K, 2SC3783, 2SC3992, 2SC3992-K, 2SC3993, 2SC3993-K, 2SC3994, 2SC3994-K, 2SC3995, 2SC3996, 2SC3997, 2SC3998, 2SD1399, 2SD1402, 2SD1403, KSC3552, KSC3552-N, KSC5030 or KSC5030-N.
