The 2SC458-B is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, collector, and base leads.
Here is an image showing the pin diagram of this transistor.The 2SC458-B transistor can have a current gain of 100 to 200. The gain of the 2SC458 will be in the range from 100 to 500, for the 2SC458-C it will be in the range from 160 to 320, for the 2SC458-D it will be in the range from 250 to 500.Sometimes the "2S" prefix is not marked on the package - the 2SC458-B might only be marked "C458-B".The complementary PNP transistor to the 2SC458-B is the 2SA1031-B.You can replace the 2SC458-B with the 2N3416, 2N3704, 2N3707, 2N3708, 2N3710, 2SC1318, 2SC1384, 2SC1815, 2SC1959, 2SC200, 2SC2002, 2SC2120, 2SC2120-O, 2SC2236, 2SC2236-O, 2SC2274, 2SC2274-E, 2SC2277, 2SC2277C, 2SC2310, 2SC2310-B, 2SC2328A, 2SC2328A-O, 2SC2458, 2SC2655, 2SC2710, 2SC2710-O, 2SC2960, 2SC2960-E, 2SC3114, 2SC3114-R, 2SC3198, 2SC3199, 2SC3202, 2SC3203, 2SC3203-O, 2SC3205, 2SC3205-O, 2SC3243, 2SC3330, 2SC3330-R, 2SC3331, 2SC3331-R, 2SC3382, 2SC3382-R, 2SC3383, 2SC3383-R, 2SC3916, 2SC3917, 2SC3918, 2SC3919, 2SC3920, 2SC3921, 2SC3922, 2SC3923, 2SC3940A, 2SC4208A, 2SC460, 2SC460C, 2SC461, 2SC461C, 2SC536, 2SC536-E, 2SC945, 2SD1207, 2SD1207-R, 2SD1347, 2SD1347R, 2SD1835, 2SD1835-R, 2SD789, 2SD789-B, 2SD863, 2SD863-E, BC182LB, BC635, C1815, C945, H945, KSC1008C, KSC1815, KSC2328A, KSC2328A-O, KSC2331, KSC815C, KSC945C, KSP8098C, KTC1008, KTC1008-Y, KTC200, KTC3198, KTC3199, KTC3202, KTC3203, KTC3203O, KTC3204, KTC3204O, KTC3205, KTC3205O, KTC3209, KTC3210, KTC3210O, KTD863, KTD863-Y or PN3643.
