LED Part Audit

flux

I’ll inspect the part metadata, look for any missing official datasheet link, then compare symbol/footprint/pin details against the sourced datasheet and summarize findings.

I found the footprint asset name IN-P416ASUW.kicad_mod, which identifies the part as Inolux IN-P416ASUW; I found the official Inolux PDF. I’m extracting the pin/package details now and checking them against the current symbol/footprint.

Completed the part audit and set the project-level Datasheet URL to the official Inolux IN-P416ASUW datasheet. I also created the detailed report: Part Datasheet Audit — LED.
Open items:
  • Metadata mismatch: current MPN is LED; it should be IN-P416ASUW.
  • Symbol issue: pins lack Anode/Cathode descriptions and are typed Unspecified.
  • Footprint issue: current pad geometry appears materially different from the Inolux recommended solder pattern.
Suggested next steps:
  1. Update MPN/manufacturer/package metadata.
  2. Set pin 1 = Anode and pin 2 = Cathode.
  3. Correct the footprint pad geometry to match the datasheet.

Symbol / Pin Metadata Check
Current schematic symbol representation uses two terminal elements:

Table

TerminalCurrent propertiesDatasheet cross-check
1Pin Number 1, Pin Type Unspecified, no Pin DescriptionShould be explicitly identified as Anode if using the current left-pad-as-pin-1 convention
2Pin Number 2, Pin Type Unspecified, no Pin DescriptionShould be explicitly identified as Cathode if using the current right-pad-as-pin-2 convention
The datasheet provides LED polarity but does not appear to formally number the terminals. It shows the practical polarity convention as left pad = anode and right pad = cathode in the recommended solder pattern/polarity symbol. Therefore, for this CAD part the safest explicit convention is:
  • Pin 1 = Anode, left pad
  • Pin 2 = Cathode, right pad
Symbol mismatches / issues
  • Pin descriptions are missing; polarity is not explicit.
  • Pin Type is Unspecified for both terminals.
  • The symbol is terminal-based rather than a recognizable LED/diode polarity symbol, so downstream users could miswire it unless the pin descriptions are fixed.
Footprint Check
Current KiCad footprint payload:
Kicad
(pad 1 smd rect (at -1.3716 0 90) (size 0.9906 1.3716) (layers F.Cu F.Paste F.Mask))
(pad 2 smd rect (at 1.3716 0 90) (size 0.9906 1.3716) (layers F.Cu F.Paste F.Mask))
Accounting for KiCad's 90° pad rotation, the effective current footprint is approximately:

Pad width transverse0.9906 mm0.63 mmMismatch
Footprint mismatch conclusion
The footprint appears materially different from the official Inolux recommended solder pattern. The pad pitch/gap and pad width are substantially off; this is not just a rounding tolerance issue. Recommended correction, assuming the datasheet land-pattern interpretation is correct:
  • Pad 1 center: x ≈ -1.75 mm
  • Pad 2 center: x ≈ +1.75 mm
  • Pad size: approximately 1.10 mm × 0.63 mm in global component coordinates
  • Pin 1 / left pad = Anode
  • Pin 2 / right pad = Cathode
Metadata mismatches / issues
  • Current MPN metadata is LED; it should be IN-P416ASUW.
  • Manufacturer is missing; it should be Inolux Corporation.
  • Package metadata is missing; it should identify the part as a side-view SMD LED / 0.6T PLCC / 3.8 × 1.0 × 0.6 mm.
  • Datasheet URL was missing before this audit and has now been set to the official Inolux PDF URL.
  1. Update part metadata: Manufacturer Part Number = IN-P416ASUW, Manufacturer Name = Inolux Corporation, Package/Case = Side-view SMD LED 0.6T PLCC, 3.8×1.0×0.6 mm.
  2. Update pin descriptions/types: Pin 1 = Anode, Pin 2 = Cathode.
  3. Correct the footprint pad geometry to match the Inolux recommended land pattern.
  4. Add or verify a clear cathode-side silkscreen/assembly marker.
