Samtec Part Review

Thought for 7 sec

I’ll review the current part metadata, find and set an official datasheet URL if missing, then compare the symbol, footprint, and pin descriptions against the datasheet.

I found the official Samtec SSQ catalog and product documents, and the part now resolves as SSQ-119-03-T-D with the official catalog URL set on the project. I’m checking the actual footprint against Samtec’s footprint/print PDFs now.

Completed the review and set the Datasheet URL to the official Samtec SSQ catalog PDF. I created the detailed findings in Part Datasheet Review — Samtec SSQ-119-03-T-D.

Open items:

Description metadata likely needs correction: it mentions gold plating and 8.08 mm stack height, while the reviewed SSQ-119-03-T-D docs indicate matte tin and 8.51 mm REF body height.
Terminal pin descriptions are missing, though the 38-pin symbol and footprint geometry otherwise match the Samtec documentation.

Suggested next steps:

Ask me to update the description metadata to match the datasheet.
Ask me to add clear Pin Description properties for terminals 01–38.
Ask me to run a focused 3D model-to-footprint alignment check.

Schematic symbol cross-check

Table

Check	Result
Terminal count	PASS — 38 terminals match 19 positions/row × 2 rows.
Pin numbering range	PASS — symbol has numbered terminals 01 through 38.
Odd/even row convention	LIKELY PASS — symbol arrangement places odd numbers on one side and even numbers on the other, matching the print convention where 01/02 share the first column, 03/04 the next, etc.
Pin electrical type	PASS — terminals are Passive, appropriate for a passive connector.
Pin descriptions	FLAG — no explicit Pin Description properties are present. For a generic socket strip this is not electrically wrong, but descriptions such as “Socket contact, column N row A/B” would improve library quality.
Pin 1 indicator in symbol	FLAG — the schematic symbol exposes terminal 01, but no explicit pin-1 note/description was observed.

PCB footprint cross-check

Observed footprint asset: SAMTEC_SSQ-119-X-X-D.kicad_mod.

Table

Check	Result
Pad count	PASS — 38 pads.
Pad numbering	PASS — pads 01 through 38 present.
Pitch along row	PASS — footprint uses 2.54 mm column pitch.
Row spacing	PASS — rows are at ±1.27 mm, giving 2.54 mm row spacing.
Row length	PASS — first-to-last column span is 45.72 mm, equal to (19−1) × 2.54 mm.
Drill size	PASS — footprint uses 1.02 mm drill, matching Samtec’s Ø0.040 in / 1.02 mm recommended hole.
Pad diameter	INFORMATIVE — footprint uses 1.53 mm pad diameter. The extracted Samtec footprint PDF did not specify a copper pad diameter, only hole diameter, so no official mismatch can be claimed.
Pin 1 marking	PASS — pad 01 is rectangular and a silk/fab marker circle appears at the pin-1 end. The extracted Samtec footprint PDF did not require a unique pad shape, but this is acceptable library convention.
Body/silk outline	PASS — silk/fab outline is about 48.77 mm × 4.95 mm, matching the official body length formula and `-D` body width reference.
3D model	NOT FULLY VERIFIED — model asset name matches SSQ-119-03-T-D, but dimensional alignment was not visually/mechanically measured beyond asset presence and footprint match.

Mismatches / concerns flagged

Project description contains likely incorrect details: it mentions “0.318 in / 8.08 mm stack height” and “gold-plated contacts.” For SSQ-119-03-T-D, the reviewed official docs indicate -T matte tin plating and 0.335 in / 8.51 mm REF body/insulator height. If “stack height” was intended as a mating-system dimension, it needs a separate citation; otherwise this text should be corrected.
Pin descriptions are missing: all 38 terminals are passive numbered terminals, but no descriptive per-pin text is present.
Original generic MPN in search result was stale: the library search for SSQ-119-X-X-D still returned an older generic placeholder result immediately after edits, while the project now resolves as SSQ-119-03-T-D. This may be indexing lag.
Copper pad diameter cannot be fully validated from extracted official footprint text: Samtec’s footprint PDF extraction confirmed the 1.02 mm drill and 2.54 mm pitch/row spacing, but did not expose an official land diameter.

Overall assessment

The symbol terminal count/numbering and footprint geometry are substantially consistent with Samtec SSQ-119-03-T-D. The most important mismatch is descriptive metadata: the part description appears to contain gold-plating and 8.08 mm stack-height claims that do not match the reviewed -T tin configuration and 8.51 mm REF body height data. The other quality improvement is adding explicit pin descriptions for terminals 01–38.
