Part Verification

flux

I’ll inspect the part metadata and geometry, find an official datasheet if needed, update the Datasheet property, then verify symbol/footprint/pins against it.

flux

I found an official Omron datasheet URL in the library metadata and updated this part project to use it; now I’m checking the pin/footprint details against that source.

Reviewed the D2FS-FL-N part information, updated the Datasheet URL to the official Omron PDF, and created the detailed D2FS-FL-N Part Verification Report.
Open items flagged:
  • Part Type is incorrectly set to Diodes; it should be Switch.
  • Pin types/descriptions are missing or underspecified.
  • Dummy terminal must remain unconnected.
  • Footprint pitch/drill/body dimensions match, but pad numbering orientation should be visually confirmed against Omron CAD/drawing before production.
Suggested next steps:
  1. Fix Part Type and terminal metadata.
  2. Mark COM/NO as passive and DUMMY as do-not-connect/mechanical.
  3. Verify pad numbering against Omron/Ultra Librarian CAD before release.

Findings:
  • The part correctly exposes three terminals: COM, NO, and DUMMY.
  • The DUMMY terminal is present, which matches the datasheet mechanical terminal set.
  • The datasheet explicitly says not to connect the dummy terminal to the circuit.
  • Pin Type is currently Unspecified on all terminals. Suggested improvement: COM and NO should be Passive; DUMMY should be Not Connected, mechanical-only, or otherwise documented as do-not-connect.
  • Pin Description properties are not populated. Suggested improvement: add descriptions such as Common contact, Normally-open contact, and Dummy mechanical terminal; do not connect.
  • The symbol is represented as separate terminal entries rather than a graphical SPST-NO switch contact symbol. This is acceptable for a part-terminal definition, but less clear for schematic readability if the published part is used directly.

Mismatches / risks flagged
  1. Part Type is wrong: the project currently says Diodes; it should be Switch.
  2. Terminal electrical types are underspecified: all pins are Unspecified; COM/NO should be passive switch contacts, and DUMMY should be clearly non-electrical/do-not-connect.
  3. Pin descriptions are missing: add datasheet-backed pin descriptions for COM, NO, and DUMMY.
  4. Pin numbering orientation is not conclusively proven from the OCR/text extraction: the datasheet clearly identifies the physical terminals as COM, NO, and Dummy, but does not provide a reliable text-extracted numeric pin-number table. The current mapping COM=1, NO=2, DUMMY=3 is common and internally consistent with the schematic and footprint, but the physical left-to-right orientation should be visually checked against the Omron drawing or official ECAD/CAD before production.
  5. Footprint pad copper size is not directly verified: hole diameter and pitch match the datasheet; copper pad diameter/annulus is library-selected and not explicitly confirmed by the extracted datasheet text.
  • Change Part Type from Diodes to Switch.
  • Set COM and NO Pin Type to Passive.
  • Set DUMMY Pin Type to Not Connected or document it as a mechanical dummy terminal that must remain unrouted.
  • Add Pin Description properties for all three terminals.
  • If production-critical, compare the pad numbering against Omron/Ultra Librarian CAD or a physical part before release.
