AI Summary

BH30-400 by BHFUSE: Polymeric PTC Resettable Fuse 30V 4A Through Hole P=5.1mm.

The Littelfuse RUEF400 is a radial leaded 30V 4.0A resettable PTC fuse with an identical 5.1 mm lead pitch and compact body profile. It handles a higher maximum fault current (100A vs 40A) while remaining under 19.3 mm seated height. The only trade-off is a slightly higher post-trip maximum resistance of 0.050 Ω compared to the original 0.045 Ω.

  • Matches 30V max voltage, 4.0A hold current, and 8.0A trip current
  • Higher maximum fault current rating (100A Imax vs 40A Imax)
  • Fits within the physical height budget (19.3 mm max seated height vs 20.2 mm max)
  • Slightly higher post-trip maximum resistance: 0.050 Ω vs 0.045 Ω

The SCHURTER PFRA.400 is a 30V 4.0A radial leaded PPTC resettable fuse with matching 5.1 mm lead pitch and primary electrical ratings. It exhibits a slightly higher post-trip resistance (0.050 Ω vs 0.045 Ω) and a larger body height of 24.8 mm.

  • Matches 30V max voltage rating, 4.0A hold current, 8.0A trip current, and 40A max fault current
  • Identical 5.1 mm radial lead pitch
  • Slightly higher post-trip maximum resistance: 0.050 Ω vs 0.045 Ω
  • Taller and wider body dimensions: 24.8 mm height x 14.4 mm width vs 20.2 mm x 14.0 mm max

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.
