Part Review Mismatch

flux

I’ll inspect the part metadata, find and set the official datasheet URL if it’s missing, then verify the symbol/footprint/pin descriptions against the datasheet and summarize any mismatches.

flux

Found the official Samtec SSQ_TH catalog PDF and set it as the part’s Datasheet URL. I’m now checking the pin list and footprint geometry against the Samtec specs.

Completed the review and set the official Samtec datasheet URL: https://suddendocs.samtec.com/catalog_english/ssq_th.pdf.
Full findings are in Part Review - SSQ-119-03-G-S. Key result: the 19-pin symbol and through-hole footprint geometry look correct, but the description ratings appear mismatched, pin descriptions are missing, and the library package case code TO is inappropriate for this connector.

Datasheet URL Update
The part project did not show a Datasheet URL in the initial project metadata. I set the part-level Datasheet URL property to the official Samtec SSQ/SSW through-hole catalog PDF:
https://suddendocs.samtec.com/catalog_english/ssq_th.pdf
A follow-up metadata readback confirmed the property is now present.

Cross-Check Results
MPN
Result: Pass.
The project MPN SSQ-119-03-G-S matches the official Samtec part number.
Manufacturer
Result: Pass.
The project lists Samtec Inc.; the official manufacturer is Samtec.
Pin Count / Positions
Result: Pass.
The schematic has 19 terminals and the library reports 19 terminals. This matches 119 as 19 positions per row and -S as single row, for 19 total contacts.
Symbol Pin Numbers
Result: Pass.
Pins are numbered 01 through 19, matching the 19-position connector. There is no functional pin assignment beyond position number for this passive connector.
Pin Type
Result: Acceptable.
All pins are passive terminals, which is appropriate for a passive connector/socket strip.
Pin Descriptions
Result: Missing / quality issue.
Pin descriptions are absent. This is not an electrical pinout error, but a published part quality issue. Recommended descriptions are simple position descriptions such as Socket contact 01, Socket contact 02, ... Socket contact 19.
Footprint Pad Count and Pitch
Result: Pass.
The footprint has 19 through-hole pads in a single row. Pad centers are spaced at 2.54 mm and the total first-to-last span is 45.72 mm, which equals 18 pitch intervals for 19 contacts.
Footprint Drill Size
Result: Pass.
The footprint uses a 1.02 mm drill, matching the Samtec footprint source value of 0.040 in / 1.02 mm typical.
Footprint Body Length / Outline
Result: Pass.
The fab outline length is approximately 48.77 mm, matching the catalog formula 2.54 mm × 19 + 0.51 mm = 48.77 mm.
Pin 1 Marking
Result: Pass.
Pad 01 is rectangular and there is a pin-1 marker near the pad-1 side. This is appropriate for orientation.
Mount / Package
Result: Mixed.
  • Mount is correctly listed as through-hole.
  • The library package_case_code value TO is inappropriate for this connector. TO suggests a transistor-outline package family, not a 1x19 through-hole connector/socket strip.
Recommended package descriptor: 1x19 2.54mm through-hole socket strip or SSQ single-row 19-position through-hole connector.
Description Ratings
Result: Mismatch.
The current description says 2.9 A per contact and 550 VAC RMS. The official Samtec SSQ data found for this part/series gives:
  • Current rating: 6.3 A per pin for SSQ/TSW, 2 pins powered.
  • Voltage rating: 465 VAC / 655 VDC.
The current description should be corrected to avoid publishing non-authoritative or incorrect electrical ratings. The current rating must include the datasheet condition 2 pins powered and should not imply all 19 contacts can carry 6.3 A simultaneously without derating.
  1. Update the description ratings:
    • Replace 2.9 A per contact with 6.3 A per pin, 2 pins powered.
    • Replace 550 VAC RMS with 465 VAC / 655 VDC.
  2. Improve the description with exact ordering-code meaning:
    • SSQ square-tail socket strip.
    • 19 positions, single row.
    • -03 straight through-hole lead style, A = 10.00 mm.
    • -G 20 microinch gold on contact, gold flash on tail.
    • LCP insulator, phosphor bronze contacts.
    • -55 °C to +125 °C with gold.
  3. Fix or remove the library package_case_code: TO value if editable.
  4. Add pin descriptions for pins 01-19:
    • Socket contact 01 through Socket contact 19.
Suggested Corrected Description
Samtec SSQ-119-03-G-S SSQ series 19-position single-row 2.54 mm pitch straight through-hole socket strip. Lead style -03 with A = 10.00 mm; -G plating gives 20 microinch gold on contact and gold flash on tail. Black LCP insulator with phosphor bronze contacts. Rated 6.3 A per pin with 2 pins powered, 465 VAC / 655 VDC, -55 °C to +125 °C.
Overall Verdict
The schematic pin count, symbol numbering, passive pin type, and through-hole footprint geometry are consistent with the official Samtec datasheet and footprint information. The main issues are metadata quality problems: missing pin descriptions, incorrect/unsupported electrical ratings in the description, and an inappropriate TO package_case_code value for a connector.
