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
-Tmatte 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.Scope
