Part Review Audit
Thought for 3 mins 12 sec
The geometry matches the extracted Kycon dimensions, but the key risk is whether the manufacturer’s bottom-view recommended layout was copied into a top-view footprint. I’m doing one more orientation check before writing the review.

View docCompleted the KCDX-5S-N part review and created the full report here: KCDX-5S-N Part Review.
Open items:
- Datasheet URL was already populated and official, but the stored value is HTTP; HTTPS is preferred.
- Symbol metadata is incomplete: pins are
Unspecifiedand lack descriptions. - Footprint dimensions/drills match the datasheet, but I flagged a possible handedness risk because the Kycon layout is explicitly “Bottom View” and the footprint appears to follow that same pin order.
Suggested next steps:
- Verify footprint handedness against the 3D model or a trusted ECAD source before manufacturing.
- Update symbol pin types/descriptions and Part Type metadata.
- If handedness is confirmed wrong, mirror/fix the footprint pin geometry.

Schematic Symbol Check
Current schematic representation uses seven standalone terminal entries:
- Signal terminals:
1,2,3,4,5 - Mechanical terminals:
MH1,MH2 - All have
Pin Type: Unspecified - No useful pin descriptions are present
Symbol Findings
Table
| Check | Result |
|---|---|
| Five DIN signal pins present | Pass |
| Two mounting holes present | Pass |
| Pin numbers align with datasheet labels | Pass for terminal labels |
| Pin descriptions | Missing |
| Pin electrical type | Weak / incomplete: all are Unspecified |
| Mechanical terminals clearly marked as non-signal | Partial: named MH1/MH2, but type remains Unspecified |
Recommended symbol metadata improvements:
- Set signal pins
1-5to Passive / connector-style pin type. - Add pin descriptions such as
DIN signal pin 1throughDIN signal pin 5. - Mark
MH1andMH2as mechanical/mounting holes or otherwise make clear they are non-signal unless intentionally connected. - Set Part Type to
Connector.
Footprint Check
Current footprint asset:
FKCDX5SN.kicad_modExtracted pad pattern:
Table
| Pad | Footprint coordinate from asset | Datasheet relation |
|---|---|---|
| 1 | (0, 0) | right outer signal hole in bottom-view drawing |
| 2 | (-7.5, 0) | center signal hole |
| 3 | (-15, 0) | left outer signal hole |
| 4 | (-2.5, -2.5) | right inner staggered signal hole |
| 5 | (-12.5, -2.5) | left inner staggered signal hole |
| MH1 | (-2.5, 9.5) | one mounting hole |
| MH2 | (-12.5, 9.5) | second mounting hole |
Footprint hole details:
- Seven through-holes present.
- Drill diameter is 1.40 mm for all seven holes, matching the datasheet callout
7-Ø1.40. - Signal pad copper size is 2.10 mm; mounting pad copper size is 1.86 mm.
- Signal span pin 3 to pin 1 is 15.00 mm, matching the drawing.
- Mounting-hole spacing is 10.00 mm, matching the drawing.
- Stagger and offsets match the extracted 12.5 / 15.0 / 3.0 mm geometry from the recommended PCB layout.
Footprint Findings
Table
| Check | Result |
|---|---|
| Pad count | Pass: 7 holes |
| Drill size | Pass: 1.40 mm |
| Relative spacing | Pass against extracted dimensions |
| Pad copper annular ring | Likely acceptable: 2.10 mm pad on 1.40 mm drill gives ~0.35 mm annular ring for signal holes |
| Pin numbering vs datasheet bottom-view drawing | Matches the datasheet bottom-view order |
| Top-view footprint handedness | Risk / needs confirmation |
Main Risk: Bottom-View Footprint Orientation
The Kycon drawing explicitly labels the recommended PCB layout as Bottom View. The current KiCad-style footprint appears to use the same left-to-right numbering order from that bottom-view drawing:
3, 5, 2, 4, 1.For a typical through-hole connector mounted on the top/component side, an EDA footprint is normally authored from the top/component view. If the manufacturer's bottom-view pattern was copied directly into a top-view footprint without mirroring, the physical pinout can be reversed left-to-right. In that case, pins
1 and 3 and pins 4 and 5 would be swapped on the assembled board.This is not proven solely from the available 2D data because the intended mounting side and Flux/KiCad view convention need to be confirmed against the 3D orientation or a known-good ECAD model. However, it is significant enough to flag before manufacturing.
An internal Flux part-quality report was filed for this orientation review.
Verdict
- Metadata is mostly correct.
- Datasheet is present and official; HTTPS is preferred.
- Symbol has correct terminal count and labels, but lacks pin descriptions and useful pin types.
- Footprint dimensions and drill sizes match the datasheet drawing.
- The only major functional concern is possible footprint handedness due to the datasheet being a bottom-view layout and the footprint apparently using that same order in a KiCad-style top-view footprint.
Recommended Next Actions
- Verify footprint handedness against the actual 3D model orientation or a trusted manufacturer/distributor ECAD model before using this part in production.
- If mounted on the top side and the current footprint is confirmed to be a direct bottom-view copy, mirror the footprint pin numbering/geometry so the top-view footprint is correct.
- Improve symbol metadata: set Part Type to Connector, set pins 1-5 to Passive, and add pin descriptions for all seven terminals.
- Prefer updating the Datasheet URL to
https://www.kycon.com/Pub_Eng_Draw/KCDX-5S-N.pdfif the part-level property editor supports it.
