Part Specifications Review

flux

I reviewed the part project for SC08-11EWA, checked the official Kingbright datasheet, and compared it against the current symbol/footprint.
Result Key part info: project vs datasheet Metadata review

Cross-check findings 1) Project description is wrong
The current project description mixes incompatible device types:
  • It says 16-segment alphanumeric
  • It also says 7 segment display
  • It says 18-DIP
The datasheet identifies this part as:
  • single-digit numeric
  • 7-segment
  • common cathode
  • right-hand decimal
  • effectively a 16-position DIP outline with 13 actual leads
So the description should be corrected.
2) Symbol does not match the datasheet cleanly
Current symbol content shows:
  • 7 segment terminals
  • 1 decimal terminal
  • 4 common terminals
But the datasheet shows:
  • 7 segment pins
  • 2 decimal-related pins: DP1 and DP2
  • 3 common cathode pins: 3, 11, 16
So the symbol has at least these issues:
  • decimal point representation mismatch: symbol has 1 DP, datasheet has 2 DP pins
  • common pin count mismatch: symbol has 4 common terminals, datasheet has 3
  • no terminal pin numbers set
  • no pin descriptions set
  • no pin groups / sub-symbol metadata set
3) Footprint appears incomplete / unmapped
The default footprint currently exposes 12 pads, while the datasheet package has:
  • 16 pin positions
  • 13 actual leaded positions
  • explicit physical numbering
Problems found:
  • pads are not mapped as numbered physical pins 1-16
  • footprint count does not align with the datasheet’s physical lead pattern
  • no clear representation of NC / no-pin positions
  • no obvious pin-number mapping between symbol terminals and footprint pads
Main mismatches to fix Highest-priority issues

Recommended corrected description
A better project description would be:
Kingbright SC08-11EWA, 20.32 mm (0.8 inch) single-digit numeric 7-segment LED display, high-efficiency red, common cathode, right-hand decimal, through-hole DIP-style package.
If you want, I can next:
  • fix the project description
  • build a correct pin-number map
  • or prepare a precise symbol/footprint mismatch checklist for updating the part project.
