Completed the part review and saved the detailed findings in Part Datasheet Review - Littelfuse 178.6764.0001. The Datasheet URL was already present, so I did not overwrite it.
Open items:
  • Footprint is high-risk/unverified: pad spacing, drill size, and hole count may not match Littelfuse’s recommended hole pattern.
  • Pin metadata is incomplete: both terminals are Unspecified with no pin descriptions.
  • Current Littelfuse rating appears to be 58 VDC / 22 A continuous / 30 A max, while the linked older datasheet shows 125 V / 30 A.
Suggested next steps:
  1. Obtain the official Littelfuse 2D print / installation drawing and rebuild or verify the footprint.
  2. Update terminal pin types/descriptions to passive fuse-holder contacts.
  3. Consider updating the Datasheet URL to the current 2025 Littelfuse datasheet if you want the newest ratings as the primary reference.

can you fix this flag issue, "Footprint for Littelfuse 178.6764.0001 appears unverified/likely incorrect. Current footprint has two PTH pads at 8.0 mm spacing with 1.6 mm drills plus one 2.8 mm center NPTH. Current Littelfuse datasheet says 7.62 mm terminal pitch;

I’ll verify the official mechanical drawing and land pattern, then correct the footprint geometry and re-check pad spacing, drills, and mounting-hole details.

flux

Fixed the footprint’s terminal pitch from 8.00 mm to 7.62 mm by moving pads 1 and 2 to ±3.81 mm; read-back confirms the corrected geometry.
  • The 1.6 mm drills and 2.8 mm center NPTH remain unchanged because the authoritative installation drawing has not yet confirmed those dimensions.
  • Filed an internal part-quality report so the source issue can be reviewed.
