Part Review Audit

flux

I’ll inspect the part metadata, look for an official datasheet if needed, then compare the symbol/footprint/pin descriptions against the datasheet and update the Datasheet property if it’s missing.

Completed the part review and created the detailed report here: Part Review Report: LFSPXO018035Bulk.
Open items:
  • Datasheet URL was already set to the official IQD URL, so no property update was needed.
  • No hard symbol or footprint mismatch found.
  • Minor quality flags: pin types are Unspecified, pin descriptions are missing, and the Bulk MPN appears obsolete with new part number LFSPXO018035.
Suggested next steps:
  1. Update terminal pin types and pin descriptions.
  2. Add lifecycle/obsolete status metadata if sourcing matters.
  3. Re-publish the cleaned-up part after metadata fixes.

Mismatches and Quality Flags
No hard symbol-pinout or footprint land-pattern mismatch was found.
Quality improvements recommended:
  1. Pin Type metadata is too generic: all terminals currently show Pin Type: Unspecified. Recommended types are: pin 1 Input, pin 2 Ground or Power In, pin 3 Output, pin 4 Power In.
  2. Pin Description metadata is missing: adding descriptions would improve library clarity and ERC behavior.
  3. Lifecycle note: the datasheet extraction indicates LFSPXO018035Bulk is obsolete and points to new part number LFSPXO018035; keep this visible if lifecycle status matters for sourcing.
Conclusion
The current Datasheet URL is already set and appears to be the official IQD URL, so it was not changed. The schematic symbol pin mapping and footprint geometry match the datasheet for the 4-pad 7 mm × 5 mm oscillator package. The main issues are metadata completeness, not electrical or mechanical mismatches.
