AI Summary

0429007.WRML by Littelfuse: 7 A 24 V 24 V Fuse Board Mount (Cartridge Style Excluded) Surface Mount 1206 (3216 Metric).

This high-inrush fast-acting chip fuse from Bel Fuse offers an extremely robust upgrade. It is ideal for circuits that experience high transient startup currents, featuring much higher voltage and interrupting ratings than the original Littelfuse model.

  • Significantly higher voltage limits (63VDC / 50VAC vs 24V)
  • Much higher breaking capacity rating (100A DC / 50A AC)
  • Excellent inrush current robustness with a high melting I²t (12.5 A²sec)
  • Higher nominal melting I²t (12.5 A²sec vs 4.9 A²sec) means it will take longer to clear during moderate overloads

The FP precision series variant from Bourns SinglFuse line provides very fast and accurate opening times. It serves as an excellent active alternative, particularly in high-precision circuits, despite minor tradeoffs in I²t and temperature limits.

  • Precision fast-acting characteristics for sensitive overcurrent protection
  • Higher maximum voltage rating of 32VDC
  • Higher breaking capacity (50A vs 35A)
  • Lower nominal melting I²t (3.3 A²sec vs 4.9 A²sec)
  • Narrower operating temperature range on the low end (-20°C vs -55°C)

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.
