Date: 2026-07-15 Reviewed available part information for the Flux part project silicon-yard/mdt420e01411: MPN, manufacturer, package/style, ...
Review complete. The Datasheet URL was already set to the official Amphenol drawing, so I left it unchanged and created the detailed report here: Part Review - MDT420E01411.
Key flags: the terminal count/numbering matches the M.2 Key E pattern, but all pin descriptions/types are missing, and the footprint readback appears 1000× too small versus the datasheet dimensions. I also filed an internal part-quality report for the footprint scale issue.
Fix the footprint scale, add pin descriptions/types, then run the part review checks again.
Inspection confirms a uniform 1000× unit error across the footprint and 69 schematic terminals needing metadata. I’m applying a parent-footprint scale correction and concise M.2 Key E signal classifications now.
Fixed the 1000× footprint scale error and added descriptions/types to all 67 contacts plus MP1/MP2. The repeated review now passes with notes; details are in Part Review – MDT420E01411.
  • No blocking mismatches remain.
  • Numbering, pad geometry, NPTH locating holes, and terminal metadata were verified.
  • Standard M.2 Key E assignments were used where the connector drawing only specifies contact geometry.
