I’ll inspect the part metadata, find and set the official datasheet URL if missing, then compare symbol/footprint/pins against the datasheet and report mismatches.

The project search shows a Molex URL, but the datasheet extractor reports no machine-visible Datasheet URL on the part, so I’m verifying the official source and will set the visible Datasheet URL property where the project tools allow it.

Completed the datasheet review and set the part’s Datasheet URL to the official Molex product PDF. I created the detailed report here: Part Datasheet Review — Molex 874271002.
Key flags: project MPN is CONN_010P_000C_1 but the official Molex MPN is 874271002; pin descriptions/types are missing/unspecified; footprint pitch and numbering match, but the drill is slightly larger than Molex’s Ø1.80 ±0.05 mm recommendation.

Part Datasheet Review — Molex 874271002
Scope
Reviewed available part information in project CONN_010P_000C_1, set the machine-visible Datasheet URL, and cross-checked the schematic terminals, PCB footprint, and pin metadata against official Molex data.

Schematic Symbol Check

CheckResult
Terminal countPass: terminals 1 through 10 are present
Pin numbersPass: Pin Number properties 1 through 10 are present
Pin descriptionsIssue: no meaningful Pin Description values found; displayed pin entries are undefined
Pin typesIssue: all terminals have Pin Type: Unspecified; for a connector these should usually be Passive unless a project convention requires otherwise
Symbol visual orderAcceptable but not physical: symbol is a simple single-column terminal list, not the 2×5 physical arrangement from the Molex drawing
Terminal designator prefixIssue/cleanup: individual terminal components show Designator Prefix: P while the part-level prefix is J

Mismatches / Action Items
  1. MPN mismatch: project Manufacturer Part Number is CONN_010P_000C_1, but official Molex MPN is 874271002. If this is intended to represent the Molex part, update the MPN property to 874271002 and keep CONN_010P_000C_1 only as project/internal name.
  2. Missing description: no explicit Description property was found. Recommended description: Mini-Fit Jr. Header, 4.20mm Pitch, Right-Angle, without Flange, 10 Circuits, Tin (Sn) over Nickel (Ni) Plating.
  3. No explicit package/case property: footprint asset is correct by filename, but there is no package/case metadata property for BOM/search.
  4. Pin descriptions missing: terminals have undefined displayed pins/no useful pin descriptions. Suggested convention: Circuit 1 through Circuit 10, or describe project-specific signal assignments when used.
  5. Pin Type unspecified: connector pins should usually be Passive to avoid ERC ambiguity.
  6. Footprint drill is slightly larger than Molex recommended tolerance: 1.8542 mm vs Ø1.80 ±0.05 mm. This is very small and likely from inch rounding, but it is technically outside the extracted drawing tolerance by ~0.004 mm.
  7. Terminal prefix inconsistency: part-level prefix is J, but terminal subcomponents show P; consider aligning metadata if Flux’s part authoring model allows it.
Overall Assessment
The footprint pad count, pitch, row spacing, row count, 3D model filename, and footprint filename align with the official Molex 874271002 / 87427-1002 data. The main issues are metadata quality and schematic pin metadata, plus a minor drill-size deviation from the Molex recommended PCB hole diameter.
