Part Datasheet Audit
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.
Thought for 9 sec
I’ll audit the part metadata, locate and attach the official Samtec datasheet if needed, then verify the symbol, footprint, and pin descriptions against it and report any discrepancies.

Audit complete. The MPN, 54-pin symbol, 2×27 through-hole footprint, 2.54 mm pitch, body dimensions, tin plating, and lead style match Samtec documentation; the existing Datasheet property was already populated, so it was preserved.
Minor gaps: Package/Case metadata and pin descriptions are absent, and the 1.04 mm drill/1.39 mm pad dimensions could not be authoritatively confirmed. Full results: Part Datasheet Audit.

SSW-127-02-T-D Part Datasheet Audit
Audit result
The part identity, 54-contact symbol, and overall footprint geometry agree with the official Samtec SSW through-hole catalog. No critical pin-count, pitch, row-count, body-size, or ordering-code mismatch was found.

Official reference: Samtec SSW Through-Hole Catalog
Ordering-code interpretation
- SSW: Tiger Buy socket strip, vertical through-hole family.
- 127: 27 positions per row.
- 02: lead style with 4.93 mm / 0.194 in solder tail.
- T: matte tin plating.
- D: dual row.
- Total contacts: 27 × 2 = 54.

Schematic symbol and terminal audit
- All 54 unique terminal numbers are present continuously from 01 through 54.
- Each terminal's Pin Number matches its terminal number.
- Every contact is typed Passive, which is appropriate for an uncommitted connector contact.
- Odd and even terminals form the alternating contacts of the two rows.
- Pin Description fields are not populated. The connector has no fixed signal assignments, so this is not an electrical mismatch, but descriptions such as “Socket contact 01” could improve metadata completeness.
Footprint audit
Observed geometry:
- 54 plated through-hole pads in 27 columns × 2 rows.
- 2.54 mm pitch along each row.
- 2.54 mm spacing between rows.
- Pad 01 is rectangular for pin-1 identification; remaining pads are circular.
- Pad diameter: 1.39 mm.
- Drill diameter: 1.04 mm.
- Contact span: 66.04 mm.
- Fabrication body outline: approximately 69.09 mm × 4.953 mm.
- Body length matches the catalog formula: 27 × 2.54 mm + 0.51 mm = 69.09 mm.
- A 3D STEP model is attached.
Mismatches and limitations
- Package/case property missing: The package is implemented correctly in the footprint, but an explicit Package or Case Code metadata property is not set.
- Pin descriptions missing: All 54 terminals lack Pin Description metadata. This is a documentation gap, not a functional pinout error.
- Pad/drill dimensions not authoritatively validated: The official catalog material available in this audit did not expose a recommended finished-hole or copper-pad diameter. The existing 1.04 mm drill and 1.39 mm pad are plausible, but should not be treated as formally confirmed by the cited Samtec drawing.
- No critical mismatch found: Contact count, numbering, pitch, row spacing, body length, orientation, plating, and lead style all align with the official part definition.
