Completed the review and created MX34R08HF4T Part Review with the detailed findings.
Open items:
  • Datasheet URL was already present and official, so no update was needed.
  • Main issues flagged: pin types/descriptions are missing, mounting-hole count needs visual verification against JAE SJ110338, and library metadata shows questionable package/manufacturer facets.
Suggested next steps:
  1. Update pins 1–8 to passive connector contacts.
  2. Mark MH1–MH6 as mechanical/hold-down holes with clear descriptions.
  3. Visually verify the six-hole footprint and pin-1 orientation against the official JAE drawing.

MX34R08HF4T Part Review
Date: 2026-07-16
Scope
Reviewed available part information for the published Flux component MX34R08HF4T, checked whether the Datasheet URL property was present, and cross-checked symbol terminals, footprint geometry, and pin descriptions against official JAE/DigiKey-hosted drawing information.
Sources Used
  • Flux project: silicon-yard/mx34r08hf4t
  • Official JAE product/drawing source already set in project: https://www.jae.com/direct/topics/topics_file_download/topics_id=64958&ext_no=06&_lang=en&v=
  • Official JAE product page discovered by web search: https://www.jae.com/connectors/series/detail/product/id=64958
  • DigiKey-hosted copy of the JAE drawing used for readable drawing metadata: https://mm.digikey.com/Volume0/opasdata/d220001/medias/docus/6612/MX34R08HF4T.pdf
Note: the direct JAE PDF is official but encrypted / not reliably text-extractable in the available tooling. The DigiKey-hosted PDF appears to be a raster/image copy of the same JAE drawing, so several dimensions were extracted from search/OCR context and should be visually checked before production release.

  • Part number: MX34R08HF4T
  • Series: MX34 / MX34R
  • Connector category: automotive board-to-cable / wire-to-board connector
  • Style: right-angle SMT male pin header, leg type no-boss
  • Positions / electrical contacts: 8
  • Total Flux terminals / footprint pads: 14 = 8 electrical contacts + 6 mounting/hold-down holes
  • Mating connector: MX34008SF4
  • Drawing number found by search/OCR: SJ110338
  • Drawing revision/date found by search/OCR: Rev. 1, 25/JUN/2010
  • Product/contact pitch: 2.2 mm
  • PCB tail pitch: 1.1 mm interleaved SMT pads, 7.7 mm span across eight tail centers
  • Current rating: 3 A
  • Mounting: SMT signal/contact pads plus through-hole solder/hold-down legs
  • PCB thickness noted in drawing context: 1.2 mm or 1.6 mm
  • Mount/leg hole drill: Ø1.2 mm +0.1 / 0
  • Signal pad land size found: 0.7 mm x 4.8 mm
  • Body width found: about 20.1 mm
  • Body depth found: about 23.55 mm
  • Mass found: about 4.0 g
Symbol Cross-check
Current symbol terminals
  • 8 contact terminals: 1, 2, 3, 4, 5, 6, 7, 8
  • 6 mounting/hold-down terminals: MH1, MH2, MH3, MH4, MH5, MH6
  • All current terminals have Pin Type: Unspecified
  • No useful Pin Description properties were found on the terminals
Symbol assessment
  • Contact count is consistent with the part: 8 electrical contacts.
  • Total terminal count is plausible if the 6 hold-down holes must be represented as terminals for footprint mapping.
  • The symbol quality is incomplete: all terminals are Unspecified, and descriptions are missing.
  • Recommended contact pin type: Passive for pins 1-8.
  • Recommended mounting-hole treatment: mark MH1-MH6 as mechanical / mounting / non-signal if supported, or at least add descriptions such as Mounting/hold-down leg hole; not a signal contact.
Footprint Cross-check
Signal pads
Current footprint has 8 rectangular SMT pads:

Table

PadX (mm)Y (mm)Size (mm)
1+2.750-10.0250.700 x 4.800
2+0.550-10.0250.700 x 4.800
3-1.650-10.0250.700 x 4.800
4-3.850-10.0250.700 x 4.800
5+3.850-10.0250.700 x 4.800
6+1.650-10.0250.700 x 4.800
7-0.550-10.0250.700 x 4.800
8-2.750-10.0250.700 x 4.800
Sorted left-to-right, the current pad order is:
4, 8, 3, 7, 2, 6, 1, 5
Assessment:
  • Pad size 0.700 mm x 4.800 mm matches the extracted drawing context.
  • 1.1 mm interleaved pitch and 7.7 mm span match the extracted drawing context.
  • The non-monotonic pad order is plausible for a two-row connector whose tails are interleaved into one SMT row. Do not renumber to simple left-to-right 1..8 without a visual check of the official drawing.
  • Primary caution: verify orientation/mirroring and pin-1 location against JAE drawing SJ110338 before production release.
Mounting / hold-down holes
Current footprint has six through-hole mounting pads:

Table

PadX (mm)Y (mm)Pad / drill
MH1-8.750+0.3251.8 mm pad / 1.2 mm drill
MH2-8.750+2.1751.8 mm pad / 1.2 mm drill
MH3-8.750+4.0251.8 mm pad / 1.2 mm drill
MH4+8.750+4.0251.8 mm pad / 1.2 mm drill
MH5+8.750+2.1751.8 mm pad / 1.2 mm drill
MH6+8.750+0.3251.8 mm pad / 1.2 mm drill
Assessment:
  • Drill diameter 1.2 mm matches the extracted drawing context.
  • Six hold-down holes may be correct for the leg type no-boss configuration, but extraction sources were inconsistent: one automated extraction mentioned four holes with low confidence, while the current footprint uses six holes.
  • This is the highest-priority mechanical item to visually verify against SJ110338.
Body outline / courtyard
  • Fab outline: 20.1 mm wide x 23.75 mm deep, close to extracted body dimensions around 20.1 mm width and 23.55 mm depth.
  • Courtyard: 22.1 mm wide x 26.85 mm deep, giving about 1 mm clearance around the main outline.
  • No obvious mismatch was found, but exact projection/keepout geometry should be visually overlaid with the official drawing for release-quality validation.
Mismatches / Issues Flagged
  1. Pin types are incomplete
    • All terminals are currently Unspecified.
    • Pins 1-8 should be connector/passive contacts.
    • MH1-MH6 should be identified as mechanical / mounting / hold-down leg holes where supported.
  2. Pin descriptions are missing
    • No pin descriptions were found.
    • Add descriptions for contacts 1-8 and mounting/hold-down holes MH1-MH6.
  3. Mounting-hole count needs visual verification
    • Current footprint has six Ø1.2 mm drilled hold-down holes.
    • Some extracted text/search context was inconsistent about whether the drawing shows four or six holes.
    • Do not approve for fabrication until SJ110338 is visually checked for the exact MH count and locations.
  4. Pad numbering is non-obvious and must not be casually changed
    • Current left-to-right order is 4, 8, 3, 7, 2, 6, 1, 5.
    • This is plausible for an interleaved right-angle two-row connector tail pattern.
    • Verify pin-1 orientation and connector view direction against JAE's drawing before release.
  5. Library packaging/manufacturer facets look imperfect
    • Project property Manufacturer Name: JAE is correct, but library search facet reports manufacturer as Other.
    • Library search metadata reports package_case_code: TO, which is not a meaningful package for this connector and should be corrected/ignored in favor of connector-specific mechanical properties.
  1. Update terminal properties:
    • Pins 1-8: Pin Type = Passive, description Connector contact N plus row/orientation note if desired.
    • MH1-MH6: description Mounting/hold-down leg hole; not a signal contact; use a mechanical/non-electrical pin type if available.
  2. Visually compare the six mounting-hole pattern against official JAE drawing SJ110338.
  3. Visually confirm footprint orientation, pin-1 marker, and non-monotonic pad order against the drawing view.
  4. Consider correcting library/package metadata so the package/case does not appear as TO for a connector.
Bottom Line
The core metadata, contact count, signal pad geometry, SMT pad size, and body outline are broadly consistent with the JAE MX34R08HF4T drawing information available. The main issues are symbol completeness (pin types/descriptions), ambiguous mechanical hold-down hole verification, and questionable library metadata for package/manufacturer facets.
