Review complete. The symbol pin numbering and footprint geometry match the MEAN WELL IRM-90-24 datasheet; key issues are metadata quality: Part Type is incorrectly “Integrated Circuits,” description says “4-Pin Carton,” pin descriptions/types are missing, and the official preferred datasheet URL is
meanwell.com.Full details are in IRM-90-24 Part Review.
Suggested next steps:
- Normalize the Datasheet URL to the official MEAN WELL link.
- Update Part Type/description/package wording.
- Add pin descriptions and electrical pin types.
Fix metadata issues
Update official datasheet
Correct part classification
Add pin details
Run review checks

Mismatches / issues to flag
- Datasheet URL property uses
meanwell-web.com; the official current MEAN WELL URL found ishttps://www.meanwell.com/Upload/PDF/IRM-90/IRM-90-spec.pdf. The existing URL was present, so it was not changed under the user's conditional instruction, but the official URL is preferable if you want the property normalized. - Part Type is set to
Integrated Circuits, which does not match the datasheet product category. This is a PCB-mount AC/DC power module / power supply, not an IC. - Description/package text says
4-Pin Carton. The datasheet describes a PCB-mount module, 87 mm × 52 mm × 29.5 mm;Cartonappears to be packaging/shipping wording, not the electrical/mechanical package. - Pin descriptions and pin electrical types are incomplete. All four terminals have
Pin Type=Unspecified, and there are no explicit Pin Description properties. The pins should be described as AC line input, AC neutral input, positive DC output, and negative DC output.
Overall result
The schematic symbol pin names/numbers and the footprint pad numbering/geometry are consistent with the MEAN WELL IRM-90 datasheet for IRM-90-24. The main problems are metadata quality: stale/non-preferred datasheet URL, incorrect Part Type category, imprecise package/description wording, and missing pin descriptions/electrical types.
