Here is an image showing the pin diagram of this transistor.The 2SC2458-O transistor can have a current gain of 70 to 140. The gain of the 2SC2458 will be in the range from 70 to 700, for the 2SC2458-BL it will be in the range from 300 to 700, for the 2SC2458-GR it will be in the range from 200 to 400, 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-O might only be marked "C2458-O".The complementary PNP transistor to the 2SC2458-O is the 2SA1048-O.The 2SC2712 (SOT-23), 2SC2712-O (SOT-23), 2SC4116 (SOT-323), 2SC4116-O (SOT-323), 2SC4738 (SOT-23), 2SC4738-O (SOT-23), FJX945 (SOT-323), FJX945O (SOT-323), KTC3875 (SOT-23), KTC3875O (SOT-23), KTC3875S (SOT-23) and KTC3875S-O (SOT-23) is the SMD version of the 2SC2458-O transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.You can replace the 2SC2458-O with the 2SC1627, 2SC1627-O, 2SC1627A, 2SC1627A-O, 2SC1815, 2SC1815O, 2SC2000, 2SC2274, 2SC2274K, 2SC2277, 2SC2655, 2SC2655O, 2SC3198, 2SC3198-O, 2SC3199, 2SC3199-O, 2SC3243, 2SC3244, 2SC3328, 2SC3328-O, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SD438, 2SD667, 2SD667A, 2SD863, BC637, BC639, C1815, C1815O, C945, C945O, KSC1008C, KSC1008CO, KSC1815, KSC1815O, KSC2331, KSC2331O, KSC945C, KSC945CO, KTC3198, KTC3198O, KTC3199, KTC3199O, KTC3209, KTC3209O, KTC3227, KTC3227O or KTD863.
