Hirose Connector Audit

flux

I found the project’s footprint asset and part metadata, but the indexed PCB data does not expose the full per-pad rule details for the KiCad footprint pads — it only confirms that pads 1–30 exist under footprint asset F-ER830P08SV2H, and that the uploaded footprint file is ER830P08SV2H.kicad_mod.
Project part identity:
  • MPN: ER8-30P-0.8SV-2H
  • Manufacturer: Hirose
  • Connector: ER8 series, 30-position, 2-row, 0.8 mm pitch board-to-board header
  • Footprint asset: ER830P08SV2H.kicad_mod
  • 3D model: ER8-30P-0.8SV-2H.stp
From the Hirose/RS data fetched for this exact MPN, the manufacturer’s recommended PCB layout is:
  • 30 contacts, 2 rows
  • Pitch: 0.8 mm
  • 15 contacts per row
  • Contact span C: 11.2 mm
  • Mounting-hole span B: 14.8 mm
  • Mounting holes: 2 × Ø1.45 ±0.08 mm, non-plated through holes
  • Connector outline / keepout A: 18.0 mm
  • Body/outline width reference: 5.6 mm
  • Pin 1 shown at left side of layout
  • Pin 2 shown on lower row
Assuming the footprint origin is centered, the expected 0.8 mm-pitch pad-center coordinates for the 30 signal pads are:

Expected mounting-hole centers, assuming centered origin:

HoleX mmY mmGeometry
MH1-7.40Ø1.45 mm NPTH
MH2+7.40Ø1.45 mm NPTH
Expected outline / placement references:
  • Overall connector/avoid area length: 18.0 mm
  • Hole-to-hole span: 14.8 mm
  • Contact-center span: 11.2 mm
  • Pin 1 orientation: left side of connector; pin 1 on the upper row, pin 2 on the lower row per manufacturer drawing orientation.
Likely manufacturing mismatch flags against a correct 0.8 mm-pitch two-row connector:
  1. Project index did not expose pad size/shape/layer details, so I could not verify exact copper pad width/length from the indexed footprint.
  2. If the actual footprint pad centers differ from the -5.6 mm … +5.6 mm sequence at 0.8 mm pitch, the connector will not solder correctly.
  3. If MH1/MH2 are not Ø1.45 mm NPTH at approximately ±7.4 mm, the plastic locating pegs may not fit.
  4. If the footprint treats the mounting holes as plated copper pads instead of non-plated mechanical holes, that would be a likely fabrication mismatch.
  5. If pin 1 is not on the left-side upper row relative to the manufacturer’s recommended layout, the connector may be mirrored or rotated incorrectly.
  6. The project metadata has a suspicious package value: “Package or Case Code: TO”, which does not match this connector package and should not be relied on for manufacturing.

Audit complete. The MPN and 30-pin count are correct, but I flagged several issues:
  • Package code TO is incorrect for this Hirose SMT board-to-board connector.
  • All 30 symbol pins lack descriptions and use Unspecified instead of passive pin types.
  • The Datasheet property already exists, so it was not changed; however, it points to an RS product page rather than the official Hirose product documentation.
  • The footprint has pads 1–30 and two mounting holes, but exact pad dimensions and hole plating were not exposed for definitive verification. Manufacturer requirements include 0.8 mm pitch, 2 × Ø1.45 mm NPTH holes at 14.8 mm spacing, and an 18.0 × 5.6 mm connector envelope.
Key ratings: 0.5 A/contact, 100 VAC, 50 mΩ maximum contact resistance, 1000 MΩ minimum insulation resistance, 300 VAC withstand, 100 mating cycles, 85 Ω differential impedance, and PCIe Gen.4/16 Gbps support. Hirose sources conflict on the upper operating temperature: the specification sheet states +85 °C, while the current product page states +125 °C.
