Part Datasheet Review and Update
Thought for 6 sec
I’ll review the part metadata and existing symbol/footprint, find the official datasheet if needed, update the Datasheet property, then verify pins and summarize any mismatches.
Worked for 1 min 9 sec
The part already had a datasheet URL, but I found the official Würth PDF and will replace the stored-upload URL with that canonical manufacturer link.
Worked for 1 min 30 sec
Reviewed the part against the Würth datasheet and created a report: Part Review: 15412094A9000.
Open items:
- Pin descriptions are missing: Pin 1 should be Cathode (−), Pin 2 should be Anode (+).
- Project-level datasheet still points to an uploaded copy; the official URL is
https://www.we-online.com/components/products/datasheet/15412094A9000.pdf. - Footprint has 2 pads, but pad dimensions were not exposed by inspection, so confirm 0.8 mm × 1.5 mm pads and polarity marking in the footprint editor.
Suggested next steps:
- Update terminal pin descriptions/pin types.
- Replace the project-level datasheet URL with the official Würth URL if editable.
- Manually verify footprint pad geometry and cathode/anode orientation.

Cross-check results
Project-level metadata
- MPN, manufacturer, description, mount, designator prefix, and 2-pad count match the datasheet.
- The project-level Datasheet URL is currently a stored uploaded PDF copy, not the canonical Würth URL. I found the official URL above. The available project metadata mutation tool does not expose Datasheet URL as an editable project-level property, so I could not replace the project-level URL directly.
Schematic symbol
- The symbol has two terminal components with Pin Number 1 and Pin Number 2.
- Datasheet pinout is Pin 1 = cathode and Pin 2 = anode.
- Mismatch / incomplete data: both terminal Pin Type fields are
Unspecified, and no Pin Description fields are present. Recommended correction: set Pin 1 description toCathode (-)and Pin 2 description toAnode (+). - Pin count itself is correct.
Footprint
- The footprint contains two pads and silk outline/marking for an LED body.
- Datasheet recommends a 1206 land pattern with 0.8 mm × 1.5 mm pads.
- Unable to fully verify pad dimensions from current layout inspection output: the layout tree and SVG view did not expose pad geometry coordinates/dimensions, even though pad nodes are present in the project summary. Visual silk/body outline appears consistent with a 1206 LED, but pad size and pad-to-pin polarity need a geometry-level check or footprint editor inspection.
Flagged mismatches / action items
- Pin descriptions missing: add Pin Description for Pin 1 = Cathode (−), Pin 2 = Anode (+).
- Pin Type unspecified: for an LED symbol this may be acceptable, but
Passiveor diode-specific terminal typing would be clearer if supported. - Project-level Datasheet URL still points to uploaded storage copy: official URL is identified but could not be written to the project-level Datasheet property with the currently available metadata tool.
- Footprint pad dimensions not fully verifiable via inspection output: confirm pads are 0.8 mm × 1.5 mm and that Pin 1 pad corresponds to the cathode polarity mark.
