Here is an image showing the pin diagram of this transistor.The 2SC3449-L transistor can have a current gain of 15 to 30. The gain of the 2SC3449 will be in the range from 15 to 50, for the 2SC3449-M it will be in the range from 20 to 40, for the 2SC3449-N it will be in the range from 30 to 50.Sometimes the "2S" prefix is not marked on the package - the 2SC3449-L might only be marked "C3449-L".You can replace the 2SC3449-L with the 2SC3450, 2SC3450-L, 2SC3451, 2SC3451-L, 2SC3461, 2SC3461-M, 2SC3552, 2SC3552-L, 2SC3797, 2SC3831, 2SC3886, 2SC3886A, 2SC3988, 2SC3988-L, 2SC3989, 2SC3989-L, 2SC3990, 2SC3990-L, 2SC3991, 2SC3991-L, 2SC3992, 2SC3992-L, 2SC3993, 2SC3993-L, 2SC3994, 2SC3994-L, 2SC3995, 2SC3996, 2SC3997, 2SC3998, KSC3552, KSC3552-R, KSC5024 or KSC5024-N.
