Part Audit Review

A

adrian95

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 audit the part metadata, source the official Samtec datasheet if needed, then verify the symbol pins and footprint geometry against it and report any discrepancies.

flux

The official Samtec document set is confirmed. I’m adding the through-hole SSW catalog datasheet URL, then I’ll finish the dimensional and pin-numbering cross-check.

Audit complete. I added the official Samtec through-hole datasheet URL and verified that the 70-pin symbol, numbering, 2.54 mm pitch, Ø1.04 mm holes, and body outline match Samtec documentation.
Flagged issues: the description is inadequate, package metadata is missing, and pins lack descriptions; no footprint geometry mismatch was found. Full results: SSW-135-02-T-D Part Audit.

SSW-135-02-T-D Part Audit
Result
The 70-pin schematic symbol and the imported through-hole footprint match the official Samtec mechanical pattern and numbering convention. The main deficiencies are incomplete part metadata and missing per-pin descriptions, not an electrical or mechanical pin-map error.

Symbol cross-check
  • Exactly 70 terminals are present, numbered continuously 01 through 70 with no duplicates or omissions.
  • Odd pins are on one symbol side and even pins on the other, matching Samtec's paired-column convention: 1/2 at one end, then 3/4, through 69/70.
  • All terminals are passive, which is appropriate.
  • No pin names or descriptions are populated beyond the number. This is a documentation-quality mismatch, not a connectivity mismatch.
Footprint cross-check
  • Pad count: 70 — correct.
  • Array: 35 columns × 2 rows — correct.
  • Column pitch: 2.54 mm — correct.
  • Row spacing: 2.54 mm — correct.
  • Drill diameter: 1.04 mm — exactly matches the official SSW-D recommended PCB layout.
  • Pad 01 is rectangular and the remaining pads are circular, providing a clear pin-1 marker.
  • Numbering is paired by column: 01/02, 03/04, …, 69/70 — correct.
  • Fabrication outline is approximately 89.41 mm × 4.95 mm — matches the official body dimensions.
  • Copper pad diameter is 1.39 mm. Samtec's footprint print specifies the finished hole but does not prescribe a copper land diameter, so this is not considered a datasheet mismatch; fabrication annular-ring requirements should still be checked against the target PCB vendor.
Flagged mismatches and omissions
  1. Description is incorrect/incomplete. Recommended description: 70-position (2×35) 2.54 mm pitch vertical through-hole socket strip, matte tin, Samtec Tiger Buy SSW series.
  2. Package property is missing. Recommended package text: Through-hole, 2×35, 2.54 mm pitch, 1.04 mm drill, 89.41 × 4.95 mm body.
  3. Pin descriptions are missing. Suggested generic description for pins 01–70: Passive socket contact.
  4. Useful classification properties are absent, including connector type, mount style, pitch, row count, positions, plating, and operating-temperature range.
  5. No manufacturer-prescribed pad diameter is given. The existing 1.39 mm land is reasonable but should be treated as a library choice rather than an official Samtec dimension.
Overall disposition
Mechanically and electrically consistent with the official Samtec documentation. The part is usable as drawn, but its metadata should be enriched before publication or reuse in a curated library.
