Neutrik Part Review
Thought for 6 sec
I’ll inspect the part metadata, find/update the official datasheet if needed, then compare symbol, footprint, and pin descriptions against the datasheet and report any mismatches.
Worked for 16 mins 14 sec
Created a project doc
Completed the part review and created NC3FAH2 Part Review with the detailed cross-check and key specs.
Open items flagged:
- Official MPN appears to be
NC3FAH2, while the part usesNC3FAH-2. - Package/case
TO, six schematic terminals, missing pin descriptions, and pads5/6look incorrect. - Pads
5/6likely should be NPTH mechanical holes, not nettable copper pads.
Suggested next steps:
- Update metadata to official Neutrik naming.
- Revise the symbol to terminals
1,2,3, andG. - Correct the footprint mechanical holes and pad naming/sizes.
- Re-run part review checks after remediation.
Fix and recheck part

Existing part information in Flux
Table
| Field | Current value | Datasheet / official value | Review |
|---|---|---|---|
| Project / part name | NC3FAH-2 | NC3FAH2 | Mismatch: official Neutrik product title uses NC3FAH2 without the hyphen. |
| Manufacturer Part Number | NC3FAH-2 | NC3FAH2 | Mismatch / alias risk. Recommended primary MPN is NC3FAH2. |
| Manufacturer Name | Neutrik | Neutrik | Matches. |
| Description | Connector, PCB; Receptacle; 3 to 5 | 3 pole female XLR receptacle, separate shell/front-panel ground, horizontal PCB mount | Current description is too generic and ambiguous. |
| Part Type | Connectors | Connector / XLR connector | Mostly correct category, but should ideally be singular Connector and include XLR details. |
| Package or Case Code | TO | XLR receptacle, A-series, horizontal PCB through-hole | Mismatch: TO is not appropriate for this connector. |
| Mount | PCB | Horizontal PCB mount / through-hole | Mostly correct but should be more specific. |
| Datasheet URL | Google-storage PDF already set | Official Neutrik PDF also found | Existing URL was present, so no Datasheet URL update was required by the request. Official direct PDF is listed above. |
| Pads / terminals | 6 | 4 electrical terminals plus 2 mechanical NPTH holes | Likely mismatch: mechanical holes appear promoted to electrical pads/terminals. |

Symbol / terminal review
Current schematic terminals:
Table
| Terminal shown | Pin Number property | Pin Type | Pin Description | Review |
|---|---|---|---|---|
| 1 | 1 | Unspecified | Missing | Should be passive; description: XLR contact 1. |
| 2 | 2 | Unspecified | Missing | Should be passive; description: XLR contact 2. |
| 3 | 3 | Unspecified | Missing | Should be passive; description: XLR contact 3. |
| G | 4 | Unspecified | Missing | Should be named/described as shell/front-panel ground, separate from Pin 1. If possible, pin number should be G, not numeric 4. |
| 5 | 5 | Unspecified | Missing | Likely should not be a schematic terminal; appears to correspond to a mechanical hole. |
| 6 | 6 | Unspecified | Missing | Likely should not be a schematic terminal; appears to correspond to a mechanical hole. |
Recommended logical terminals:
1, 2, 3, and G only. The two mechanical support holes should not be nettable schematic pins unless the manufacturer drawing explicitly identifies them as plated/electrical contacts.Footprint review
Current footprint asset pad list from imported KiCad payload:
Table
| Current pad | At (mm) | Size (mm) | Drill (mm) | Review |
|---|---|---|---|---|
| 1 | (0.000, 0.000) | 2.4 x 2.4 | 1.6 | Electrical pad; annular ring smaller than KiCad reference. |
| 2 | (7.620, 0.635) | 2.4 x 2.4 | 1.6 | Electrical pad; coordinates look like a rotated reference footprint. |
| 3 | (3.810, 4.450) | 1.8 x 1.8 | 1.2 | Electrical pad; annular ring smaller than KiCad reference. |
| 4 / G | (-3.810, -5.720) | 1.8 x 1.8 | 1.2 | Shell/front-panel ground should be named G; numeric pad 4 is semantically risky. |
| 5 | (7.620, -4.450) | 2.4 x 2.4 | 1.6 | Likely should be NPTH mechanical hole, not copper/nettable pad. |
| 6 | (0.000, -8.890) | 2.4 x 2.4 | 1.6 | Likely should be NPTH mechanical hole, not copper/nettable pad. |
KiCad reference footprint for Neutrik NC3FAH2 models the part as four nettable pads plus two NPTH holes:
Table
| Reference feature | At (mm) | Size (mm) | Drill (mm) |
|---|---|---|---|
| Pad 1 | (0, 0) | 3.4 x 3.4 | 1.6 |
| Pad 2 | (-0.635, 7.62) | 3.4 x 3.4 | 1.6 |
| Pad 3 | (-4.45, 3.81) | 2.9 x 2.9 | 1.2 |
| Pad G | (5.72, -4.44) | 2.9 x 2.9 | 1.2 |
| NPTH | (3.81, 7.62) | 1.6 x 1.6 | 1.6 |
| NPTH | (8.89, 0) | 1.6 x 1.6 | 1.6 |
The current Flux footprint appears to be a rotated variant, which is not necessarily wrong, but the mechanical holes becoming pads
5 and 6 is a likely functional/library issue. Pad copper sizes are also smaller than the KiCad reference, reducing annular ring and mechanical robustness for a connector.Mismatches / issues flagged
- Official MPN appears to be
NC3FAH2, while the part usesNC3FAH-2. Package or Case Code = TOis inappropriate for this XLR connector.- Description is too generic and does not capture 3-pole female XLR, horizontal PCB mount, and separate shell/front-panel ground.
- Symbol exposes six terminals; likely correct electrical terminals are
1,2,3, andGonly. - Terminals
5and6likely represent mechanical NPTH holes and should not be nettable schematic terminals. Gis modeled with Pin Number4; the official/reference naming usesGfor the separate shell/front-panel ground contact.- All terminal Pin Type fields are
Unspecified; connector pins should normally bePassive, withGdescribed as shell/chassis/front-panel ground. - Pin descriptions are missing for all terminals.
- Footprint pads
5and6likely should be NPTH mechanical holes, not copper pads. - Pad copper sizes are smaller than the KiCad reference footprint and should be verified for annular ring / mechanical stress robustness.
Actions taken
- Confirmed a Datasheet URL was already present, so no Datasheet URL update was required by the request.
- Found the official Neutrik product page and direct PDF URL.
- Cross-checked metadata, symbol terminals, terminal descriptions, and footprint against official Neutrik information and KiCad reference footprint.
- Filed an internal Flux part-quality report for the suspected symbol/footprint/metadata problems.
Suggested remediation
- Update metadata to use official MPN
NC3FAH2and a connector-specific package/case value. - Revise the symbol to expose
1,2,3, andGonly. - Add pin descriptions and set pin type to
Passiveor equivalent. - Convert the two mechanical support holes to NPTH/non-nettable footprint features.
- Rename/map the shell/front-panel ground pad as
Grather than numeric4if supported. - Verify pad sizes against the official Neutrik drawing and/or use the KiCad reference annular ring sizes if appropriate for manufacturing robustness.
