| FFF Compatibility | Matches the exact physical footprint, pin dimensions, and 10mm PCB terminal spacing of the original part.Direct manufacturer equivalent with identical 5x20mm cartridge fuse mounting and vertical profile dimensions.Matches all electrical ratings including 250V voltage, 6.3A VDE / 12A UL current ratings, and the IP54 protection class. | Uses the exact same terminal layout and 10mm pin spacing on the PCB.Identical physical dimensions and vertical shape, fitting the same 5x20mm cartridge fuses.Provides lower environmental protection (IP40 rating) because it lacks the silicon sealing ring found on the 853 series. | ||
 AI Summary | 853 0000 100 by Littelfuse: Fuse Holder 6.3 A 250V 1 Circuit Cartridge Through Hole. | This is the active, direct successor part number from the same manufacturer, offering a perfect drop-in replacement. The suffix '9' specifies bulk packaging, but the physical component remains completely identical to the obsolete original. It retains the same IP54 protection level with full electrical and mechanical compatibility.
| This is an active sibling variant from Littelfuse's 852 series. It shares the exact same physical footprint, height, and electrical ratings as the original, making it physically interchangeable. However, it provides IP40 environmental protection instead of the original's IP54 since it lacks the integrated silicon sealing ring.
