ORH-YG35A is a same-size 0805 LED candidate with a yellow-green output.
NCD0805Y1 is a yellow 0805 SMD LED. Possible substitutes need optical, polarity, and current checks before approval.
Some candidates are 20mA vs 25mA target.
Kept parts share 0805 package.
No firmware interface.
Lifecycle data is limited.
No verified pin-compatible replacement is proven from the provided evidence.
Start with ORH-YG35A or XL-2012UOC only if color shift is acceptable.
Optical color and brightness differ from the 588nm yellow target.

| Feature / factor | NCD0805Y1 | ORH-YG35A | XL-2012UOC | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 0805 | 0805 | 0805 | 0805 — same nominal case; XL-2012UOC: same nominal case | |
| Pinout | 2-pin LED | 2-pin LED | 2-pin LED | 2-pin LED — polarity not checked; XL-2012UOC: polarity not checked | |
| Voltage | 2.0V typ | 2.0V typ | 1.8-2.4V | 2.0V typ / 1.8-2.4V — typ Vf aligns; XL-2012UOC: range covers target | |
| Current | 25mA | 20mA | 20mA | 20mA — may need derating; XL-2012UOC: reduce drive current | |
| Application | yellow 588nm | yellow-green 570nm | orange 600-610nm | yellow-green 570nm / orange 600-610nm — visible color shift; XL-2012UOC: color is warmer |
ORH-YG35A is the closest kept option, but it is yellow-green and needs FAE review.
