Part Datasheet Review

flux

I’ll inspect the part metadata and existing symbol/footprint, find the official datasheet if needed, update the Datasheet property, then document the cross-check and mismatches.

The part already has an official CUI datasheet URL set, so I’m using that as the source of truth and moving into pin/footprint verification.

Completed the datasheet review for VAWQ6-Q24-S5H and created Part Datasheet Review: VAWQ6-Q24-S5H.
Open items:
  • Datasheet URL was already set and official, so no property update was needed.
  • Pinout and footprint geometry match the datasheet.
  • Flagged metadata issues: wrong library classification/subtype, manufacturer facet showing “Other,” footprint/value name referencing S12H, and missing pin descriptions/types.
Suggested next steps:
  1. Clean up the part metadata and terminal pin descriptions.
  2. Rename/update the footprint value metadata from S12H to S5H if appropriate.
  3. Re-run a final publish/manufacturing readiness review.

Symbol observation: the functional designators and pin numbers match the datasheet. However, the individual terminal properties have Pin Type = Unspecified and no Pin Description text, so ERC/documentation quality is lower than it could be. Recommended terminal types/descriptions are: power input for +Vin/-Vin, power output for +Vo/-Vo, and not-connected for NC pins.

Flagged Mismatches / Risks
  1. Library classification is incorrect: the part is categorized as Integrated Circuits with subtype Logic and logicFunction AND, but it is an isolated DC/DC converter power module.
  2. Library manufacturer facet shows Other, while the Manufacturer Name property correctly says CUI Inc.
  3. Footprint asset and value text reference VAWQ6Q24S12H instead of VAWQ6-Q24-S5H. The geometry appears compatible for the VAWQ6 series, but the metadata should be renamed to avoid BOM/review confusion.
  4. Pin descriptions and pin electrical types are missing or Unspecified. Pin numbers/designators are correct, but documentation/ERC quality would improve if terminal properties were populated from the datasheet.
  5. Description is generic/abbreviated. It is not electrically wrong, but a clearer description would be: 5 V, 1 A, 5 W isolated DC/DC converter, 9-36 V input, 3000 Vdc isolation, 24-pin DIP style.
Conclusion
The schematic symbol pin numbers and functional terminal names match the official CUI VAWQ6 datasheet for the single-output VAWQ6-Q24-S5H. The footprint geometry and populated through-hole pad positions also match the datasheet mechanical data. The main issues are metadata quality, not pinout/land-pattern geometry: part classification, manufacturer facet, footprint/value naming, and missing terminal pin descriptions/types should be cleaned up before publishing or manufacturing review.
