Part Data Review and Validation

Review all available part information (MPN, package, pin count, description, properties). If no datasheet URL is already set, search the web for the official datasheet and update the part's Datasheet property with the URL. Then cross-check the schematic symbol, footprint, and pin descriptions against the datasheet. Summarize key specs and flag any mismatches.

I’ll inspect the part metadata, find and set the official datasheet URL if missing, then compare the symbol/footprint/pins against the datasheet and summarize any mismatches.

Completed the part review and created a detailed report: Part Review: SEAM-40-01-L-10-2-RA-K-TR.
Open items:
  • Datasheet URL was already set to Samtec’s official product page, so I did not overwrite it.
  • Main flagged issue: Package or Case Code is set to TO, which does not match this connector.
  • Pin descriptions are minimal/unspecified, though the 400 contact pins plus mounting/tooling pad count broadly match Samtec documentation.
Suggested next steps:
  1. Update the package/property metadata to a connector-specific descriptor.
  2. Add richer pin descriptions for contact pins and mounting/tooling holes.
  3. Optionally add Samtec’s product spec, series print, and footprint PDF URLs as reference properties.

Schematic symbol check
  • Schematic contains 404 Terminal components.
  • Contact terminals are named as grid positions using rows A, B, C, D, E, F, G, H, J, K and columns 1–40. This yields 400 signal/contact terminals, matching the expected 40 × 10 contact array.
  • The additional four schematic terminals are MH1–MH4, matching the recommended footprint’s 4× soldered PTH mounting/tooling holes.
  • Pin descriptions/types are sparse: sampled terminals have Pin Type: Unspecified and no meaningful pin description beyond the pin number/designator. For an open-pin-field connector this is electrically acceptable but not richly documented.
Footprint check
  • PCB layout summary reports 406 pads and one footprint.
  • Observed pad designators include the 400 contact positions plus MH1–MH4. The remaining two pads are consistent with the recommended footprint’s 2× NPTH holes, though the layout tree output was truncated before all pad metadata could be inspected.
  • Recommended Samtec footprint calls for:
    • 400 SMT contact pads
    • 4× 0.045 in / 1.14 mm PTH holes to be soldered using paste-in-hole technology
    • 2× 0.050 in / 1.27 mm NPTH holes
    • 0.050 in / 1.27 mm pitch in both directions
    • SMT pad size approximately 0.008 in × 0.025 in [0.20 mm × 0.64 mm], full radius noted in the footprint drawing
  • Layout pad count of 406 matches the expected 400 + 4 PTH + 2 NPTH total.
Flagged mismatches / issues
  1. Package or Case Code property appears wrong: Project property is set to TO, which is not appropriate for this connector. A better value would be a connector-specific package/footprint descriptor such as SEAM-RA 40x10 1.27mm right-angle SMT or similar.
  2. Pin descriptions are minimal: Terminals are Pin Type: Unspecified and do not include descriptive labels such as “Open pin-field contact A1” or “mounting/tooling hole.” This may be acceptable for a generic open-field connector, but richer pin descriptions would improve library quality.
  3. Datasheet URL points to product page, not PDF: This is still an official Samtec URL and was already set. If desired, the Datasheet URL could be changed to the official product specification PDF or the Series Print/Footprint URLs could be added as reference/documentation properties.
  4. Cannot fully verify pad geometry from current layout output: The layout tree confirmed counts/designators at a high level, but did not expose full pad dimensions in the available/truncated response. Geometry should be checked visually or with a more detailed footprint export against Samtec’s footprint PDF before release.
Overall conclusion
The part identity, MPN, row/column contact count, and total footprint pad count are broadly consistent with the official Samtec documentation for SEAM-40-01-L-10-2-RA-K-TR. The main cleanup items are metadata quality rather than a clear electrical/pin-count failure: fix the Package or Case Code, optionally add richer pin descriptions, and consider adding the PDF references for product spec/print/footprint.
