Part Review and Datasheet Verification

flux

Completed the FGDS-2A-50V part review and saved the detailed findings in fgds-2a-50v-part-review. The pin numbers/names and 5-pad footprint count match the GAIA datasheet; flagged issues are missing pin descriptions/unspecified pin types, a non-official uploaded Datasheet URL, and incomplete visibility into pad drill/coordinate geometry.
Open items:
  • Decide whether to replace the existing Datasheet URL with the official GAIA PDF.
  • Verify footprint pad drill/spacing against the datasheet mechanical drawing before release.
Suggested next steps:
  1. Update terminal pin descriptions/types from the datasheet.
  2. Switch Datasheet URL to the official GAIA URL.
  3. Perform a footprint geometry audit against the datasheet bottom-view drawing.

Set the terminal pin descriptions and appropriate pin types from the datasheet.

I’ll update each of the five terminals with the datasheet function and a more appropriate electrical pin type, then re-read the schematic to verify.

flux

Updated and verified all five terminal descriptions and pin types from the datasheet.
Open items:
  • None.
Suggested next steps:
  1. Replace the existing uploaded datasheet URL with the official GAIA URL if desired.
  2. Audit footprint drill/spacing against the datasheet mechanical drawing.

  • Part type: EMI / RFI Components
  • Package/case: Module
  • Pin count / pads: 5
  • Existing Datasheet URL property: https://storage.googleapis.com/graviton-electric-symbols/document_assets/user-uploaded/2d3512c000435847fa88c9c526ac7f73577c1c718cf6ec6893871ad2e364889f.pdf
  • Official datasheet found: https://www.gaia-converter.com/wp-content/uploads/datasheets/FGDS-2A-50V.pdf — GAIA Converter, Revision G, 10/18
The part already had a Datasheet URL, so the property was not overwritten.

Footprint cross-check
  • The footprint contains 5 pad nodes, matching the datasheet pin count.
  • The visible silkscreen/body outline is approximately 20.5 mm x 35.5 mm, matching the datasheet body dimensions.
  • The datasheet states 0.73 mm diameter pins. The current inspection output did not expose individual pad hole diameters, pad sizes, or pad coordinates, so drill diameter and exact pin pattern could not be fully verified from the available layout data.
Mismatches / issues flagged
  1. Pin descriptions are not populated on the terminal components. The schematic inspection shows each terminal pin as undefined and Pin Type as Unspecified. The pin numbers and terminal names match, but the pin descriptions/types should be filled from the datasheet for library quality.
  2. Datasheet URL is not the official GAIA URL. A Datasheet URL is present, but it points to a user-uploaded PDF. The official GAIA PDF was found at https://www.gaia-converter.com/wp-content/uploads/datasheets/FGDS-2A-50V.pdf. Because the request said to update only if no Datasheet URL was already set, I did not overwrite it.
  3. Footprint pad geometry needs deeper verification. Pin count and body outline match, but pad drill/hole diameter, plated-through status, and exact center coordinates were not visible in the available layout inspection output.
  • Add terminal pin descriptions and set appropriate pin types for all five symbol terminals.
  • Consider replacing the Datasheet URL with the official GAIA URL if that is preferred over the current uploaded copy.
  • Verify footprint pad hole diameter against the 0.73 mm pin diameter and confirm the datasheet bottom-view pin coordinate pattern before publishing/releasing the part.
