4) Cross-check: symbol and footprint vs datasheet

What matches

CheckResult
Signal positionsMatch: project has 26 numbered contacts
Mechanical holesMatch: project includes 2 mounting-hole pads
Overall pin conceptMatch: 26 electrical contacts plus 2 mechanical features is consistent with the datasheet

Issues / risks found

IssueRisk
The part project is built as separate generic pins/pads rather than a single fully defined connector symbol with named pinsHigh risk of poor library quality, harder reuse, weak BOM behavior, and easier accidental mis-ordering
All symbol pins are marked Pin Type: UnspecifiedERC quality is degraded; incorrect interface checking may be missed
No resolved purchasable BOM entry is shown for the placed object setRisk of manufacturing/order confusion if this published part is reused without a proper mapped component identity
Project description shows Connector Length 57.4 mm, while the datasheet extraction reports 62 mm [2.44 in]Mechanical metadata mismatch; this can cause enclosure or placement mistakes if someone trusts the project properties instead of the datasheet
No extracted evidence of footprint drill sizes, pad sizes, row spacing, or exact mounting-hole coordinates from the current accessible dataCannot fully verify manufacturability of the footprint land pattern from the available extracted geometry alone
Datasheet-specific connector attributes like upper locking, 1 key, right angle, and gold pins are not clearly represented as structured footprint/symbol constraintsRisk of creating a visually similar but mechanically wrong part variant
Bottom line

Status

AreaResult
MPN / description consistencyMostly good
Datasheet presenceGood
Electrical metadata coverageGood
Symbol qualityNeeds improvement
Footprint manufacturability verificationIncomplete from currently extractable dimensions
Ordering riskModerate to high unless the part is converted into a proper single connector component with locked metadata
Most important flags
  • The mechanical length mismatch (57.4 mm in project description vs 62 mm in datasheet) should be corrected.
  • The part should not rely on 28 generic internal pins/pads as its final published representation if you want safe reuse.
  • The footprint cannot be fully signed off for manufacturing until the exact PCB drawing dimensions are verified against the TE product drawing/CAD files.
If you want, I can next do one focused pass on the mechanical verification only and extract/check the exact PCB hole pattern from the TE drawing/CAD files.
