Part Verification and Datasheet Update
Thought for 3 sec
I’ll review the part metadata, locate and attach the official datasheet if missing, then compare the symbol, footprint, and pin descriptions against it.
Worked for 2 mins 46 sec
Reviewed the JST SM02B-SFKH-TF part data and created a verification report: Part Verification: SM02B-SFKH-TF.
Open items:
- Project description says 250 V, but the JST datasheet lists 350 V AC/DC.
- Current Datasheet URL is a user-uploaded PDF; the official JST URL found is
https://www.jst-mfg.com/product/pdf/eng/eSFK.pdf. - Symbol terminals lack pin descriptions and all pin types are unspecified.
- Footprint has the expected 4 pads, but exact pad geometry could not be fully verified from the structured tool output.
Suggested next steps:
- Update the voltage rating/description to 350 V if you want it to match JST’s datasheet.
- Replace the uploaded Datasheet URL with the official JST URL for traceability.
- Add pin descriptions for circuits 1/2 and the two reinforcement pads.

Symbol cross-check
The schematic symbol contains four terminal objects:
Table
| Flux terminal | Pin Number property | Expected function | Result |
|---|---|---|---|
1 | 1 | Circuit/contact 1 | Matches |
2 | 2 | Circuit/contact 2 | Matches |
MP_1 | 3 | Mechanical/reinforcement solder tab | Acceptable numbering choice |
MP_2 | 4 | Mechanical/reinforcement solder tab | Acceptable numbering choice |
Notes:
- The datasheet identifies two electrical circuits and two reinforcement solder points. Modeling the reinforcement tabs as separate footprint/symbol terminals is acceptable for PCB land pattern completeness.
- Pin type is currently
Unspecifiedfor all terminals. For library quality, contact pins should be electrical/passive or connector pins, whileMP_1andMP_2should be identified as mechanical/shield/mounting pads if Flux supports that pin type. - Pin descriptions are not populated; adding descriptions would improve clarity.
Footprint cross-check
The footprint has four pad nodes matching the expected two contacts plus two reinforcement pads. Silkscreen/fab outline corresponds to a compact right-angle/side-entry SMT connector body.
Observed limitations from the current layout data:
- The tool output did not expose pad dimensions/coordinates in structured form, so the exact JST recommended land pattern dimensions could not be fully machine-verified from the current data.
- The flat layout view shows the outline and silkscreen but did not render pad geometry in the inspected SVG output, so pad geometry should be visually checked in the PCB editor against the datasheet recommended PCB layout.
Mismatches / issues flagged
- Voltage rating mismatch in description: project description says 250 V, while the JST datasheet general specification says 350 V AC/DC. Update the description/properties to 350 V unless intentionally using a distributor-specific derated value.
- Datasheet URL consistency: current project metadata points to a user-uploaded PDF, while the official JST URL available from the part/library metadata is
https://www.jst-mfg.com/product/pdf/eng/eSFK.pdf. The existing URL is valid-looking, but the official manufacturer URL is preferable for traceability. - Pin descriptions missing: terminals lack explicit descriptions such as
Circuit 1,Circuit 2,Mounting/Reinforcement Pad 1, andMounting/Reinforcement Pad 2. - Pin types unspecified: all terminal pin types are unspecified; electrical contacts and mechanical pads should be differentiated if supported.
- Footprint pad geometry not fully verified by tool output: terminal count matches the datasheet, but pad sizes/locations need direct editor/datasheet visual verification because structured dimensions were not returned.
Overall verdict
The part identity, manufacturer, mount style, two-circuit connector model, and four-terminal modeling strategy are broadly consistent with the JST SM02B-SFKH-TF datasheet. The main metadata correction is the voltage rating, and the main symbol-quality improvements are pin descriptions and pin type classification.
