Part Review and Datasheet Cross-Check
Thought for 30 sec
The Datasheet URL is already set to Molex’s part-detail PDF, so no property update was needed. I’m extracting the official dimensions/specs now and comparing them to the symbol and footprint.
Worked for 3 mins 34 sec
Completed the part review and saved the detailed report in
part-datasheet-cross-check-molex-5031542290.Key result: the Datasheet URL was already set to Molex, symbol pins 1–22 match the 22-circuit part, but the footprint signal pads appear larger than the Molex recommended land pattern found online, and retention pads 23/24 are present only in the footprint.
Open items:
- Verify the pad-size discrepancy directly against the official Molex sales drawing before manufacturing.
- Decide whether retention pads 23/24 should remain mechanical-only or be exposed in the symbol.
Suggested next steps:
- Update/replace the footprint to match the official Molex land pattern.
- Add pin descriptions like
Contact 1…Contact 22. - Add a reference/document URL for the official Molex sales drawing.
Fix footprint pads
Expose retention pads
Add pin descriptions

Schematic symbol check
Observed
- Schematic has 22 terminal components.
- Pin numbers present: 1 through 22, no duplicates found.
- Each terminal is generic with
Pin Type: Unspecified. - No explicit pin descriptions beyond pin numbers were found.
Cross-check
- 22 logical signal/contact terminals matches the 22-circuit Molex part data.
- For a passive connector where each contact is user-assigned, unspecified pin type is acceptable.
- Pin descriptions are minimal; this is not electrically wrong, but richer descriptions such as
Contact 1…Contact 22would improve library quality. - Footprint includes two additional SMT retention/solder tabs as pads 23 and 24; these are not present as schematic terminals. This may be acceptable if treated as non-electrical mechanical retention pads, but should be intentional. If users need to tie shell/retention tabs to a net, expose pins 23/24 or document them as mechanical-only/excluded terminals.
Footprint check
Observed footprint
From
CONN_503154_22_MOL.kicad_mod:- 22 signal pads, numbered 1–22.
- Two additional SMT retention pads, numbered 23 and 24.
- Signal pad pitch along X: 1.50 mm.
- Signal pad rows at approximately Y = +4.703 mm and Y = -4.697 mm.
- Signal pad size: 0.8128 mm × 2.54 mm.
- Retention pad size: 1.905 mm × 5.1562 mm.
- Fabrication body outline approximately 20.8026 mm × 9.144 mm.
- Courtyard approximately 22.473 mm × 12.448 mm.
Cross-check against Molex drawing/search-extracted data
- Row count, 22 numbered signal pads, 1.50 mm pitch, two retention pads, SMT vertical style, and general body/courtyard scale are consistent with a Molex 503154-2290 footprint.
- The searched Molex sales drawing summary indicates recommended signal land pattern around 0.45 mm × 1.60 mm and 0.10 mm stencil with 100% aperture ratio. The project footprint signal pads are 0.8128 mm × 2.54 mm, which is significantly larger.
Mismatches / issues flagged
- Potential footprint land-pattern mismatch: project signal pads are 0.8128 mm × 2.54 mm, while the official Molex recommended pattern surfaced in search is approximately 0.45 mm × 1.60 mm. This should be verified directly against the official sales drawing before manufacturing.
- Mechanical retention pads not represented in schematic: footprint pads 23 and 24 exist, but the schematic symbol only exposes pins 1–22. This is acceptable only if those pads are intentionally mechanical/no-connect solder retention pads.
- Pin descriptions are sparse: symbol terminals have no explicit
Pin Descriptionsuch asContact 1throughContact 22; pin type isUnspecified. This is acceptable for a generic connector but less complete than preferred library metadata. - Datasheet property already set: no update was required. However, the currently set Molex part-detail PDF is limited; adding a separate reference/design URL to the official sales drawing may improve future footprint validation.
Review checks
Flux part review checks queried for datasheet, terminals, pin numbers, missing properties, and missing footprint returned no open warnings/errors at the time of review.
Recommendation
Before release/manufacturing, verify the footprint against the official Molex sales drawing
5031540000-SD / part-specific drawing, especially the SMT signal pad size and retention pad geometry. If the official land pattern confirms smaller pads, revise the footprint; otherwise document why the larger pads are intentional, such as a third-party CAD-library variant or assembly-process requirement.
