Part Review and Datasheet Update

flux

I reviewed the part project against the current project metadata, the terminal set in the schematic, the default footprint, and the official Harwin web/product-page data. I used the datasheet-first audit approach for pin-count and metadata verification, where the datasheet is the source of truth and pin count should match exactly
What I found Part metadata currently in the project

Official datasheet / product-page facts I could confirm
From Harwin’s official product information for this exact MPN:
  • Series/family: Gecko male horizontal / right-angle connector
  • Contact count: 25 + 25 = 50 contacts
  • Pitch: 1.25 mm
  • Current rating: 2.8 A max per individual contact
  • Simultaneous current rating: 2.0 A max at 25°C
  • Operating temperature: -65°C to +150°C
  • Orientation / mount style: right-angle, through-hole
Schematic symbol audit Good
  • The project contains 50 terminal components, numbered 1 through 50.
  • Each terminal’s Pin Number property matches its designator, so the basic numbering set is internally consistent.
  • The count lines up with the expected 50 contacts.
Mismatches / issues
  • All 50 terminals have Pin Type = Unspecified.
    • For a connector like this, these should normally be Passive, not Unspecified.
  • I did not find populated Pin Description values.
  • I also did not find contact names beyond simple numbering, so the symbol currently behaves like a bare numbered connector rather than a documented part.
Footprint audit Good
  • The default footprint contains pads 1 through 50, which matches the schematic contact count.
  • There are also 2 extra mounting/mechanical pads labeled 51 and 52 under the footprint mounts section.
Needs verification
  • The 50 electrical pads appear numerically aligned with the symbol.
  • The extra 51/52 pads are likely mechanical support / locating features, which is plausible for this connector style, but I could not fully verify the exact drill/land dimensions from the currently extractable PDF content.
  • I could confirm the footprint has:
    • 50 electrical pads
    • 2 mounting/mechanical pads
  • I could not conclusively verify from the available extraction:
    • exact drill sizes
    • exact row spacing
    • exact body dimensions
    • exact Harwin recommended land pattern geometry

Suggested property additions
These would improve the part record without changing the electrical model:
  • Package or Case Code: something like the Harwin family/package identifier for this right-angle 50-contact Gecko variant
  • Max Current: 2.8 A
  • Operating Temperature: -65°C to +150°C
Summary
  • The part project is mostly structurally correct:
    • correct MPN/manufacturer
    • datasheet URL already present
    • 50-pin symbol
    • 50-pad electrical footprint
  • The main issues are metadata completeness and symbol terminal properties:
    • all contacts are still Unspecified
    • pin descriptions are missing
    • package/current/temperature properties are missing
  • The only footprint concern I’d flag right now is the presence of pads 51/52 without confirmed drawing extraction; they are probably mechanical, but I can’t certify them from the available parsed datasheet content alone.
If you want, I can do the next pass and:
  • set all connector contacts to Passive
  • add missing project properties like Max Current and Operating Temperature
  • tighten the description
  • flag whether pads 51/52 should stay as mechanical features or be converted/renamed more clearly
