- An official datasheet URL was already present in the project context.
- I also ensured the project’s Datasheet property points to the official Kingbright PDF:
Metadata review
| Field | In project | In datasheet | Status |
|---|---|---|---|
| MPN | SC08-11EWA | SC08-11EWA | Match |
| Manufacturer | Kingbright | Kingbright | Match |
| Package / case | 16-DIP | DIP-style package, 16 positions with 13 populated leads | Partial mismatch / misleading label |

- It says 16-segment alphanumeric
- It also says 7 segment display
- It says 18-DIP
- single-digit numeric
- 7-segment
- common cathode
- right-hand decimal
- effectively a 16-position DIP outline with 13 actual leads
- 7 segment terminals
- 1 decimal terminal
- 4 common terminals
- 7 segment pins
- 2 decimal-related pins: DP1 and DP2
- 3 common cathode pins: 3, 11, 16
- 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
- 16 pin positions
- 13 actual leaded positions
- explicit physical numbering
- 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
Highest-priority issues
| Area | Issue | Severity |
|---|---|---|
| Description | Says 16-segment/alphanumeric/18-DIP, but datasheet says 7-segment numeric | High |
| Symbol | Common terminal count does not match datasheet | High |
| Symbol | Decimal pin representation does not match datasheet | High |
| Symbol | Missing pin numbers/descriptions | High |
| Footprint | Pad structure not clearly aligned to numbered physical package | High |
| Footprint | Only 12 pads visible vs datasheet’s 13 populated leads | High |
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.
- fix the project description
- build a correct pin-number map
- or prepare a precise symbol/footprint mismatch checklist for updating the part project.
