Here is an image showing the pin diagram of this transistor.The 2SC2458-BL transistor can have a current gain of 300 to 700. The gain of the 2SC2458 will be in the range from 70 to 700, for the 2SC2458-GR it will be in the range from 200 to 400, for the 2SC2458-O it will be in the range from 70 to 140, for the 2SC2458-Y it will be in the range from 120 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC2458-BL might only be marked "C2458-BL".The 2SC2712 (SOT-23), 2SC4116 (SOT-323), 2SC4738 (SOT-23), FJX945 (SOT-323), KTC3875 (SOT-23), KTC3875S (SOT-23) and PMBT6428 (SOT-23) is the SMD version of the 2SC2458-BL transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2458-BL with the 2SC1815, 2SC3198, 2SC3198-BL, 2SC3199, 2SC3199-BL, 2SC3330, 2SC3331, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SD789, C1815, C945, KSC1815, KSC945C, KTC1006, KTC3198, KTC3198BL, KTC3199 or KTC3199BL.
