XINGLIGHT
A 5mm green LED with same package and electricals, but significantly lower brightness and a green diffused lens.
Reviewing alternatives for the XL-502UGC, a high-brightness 5mm green LED. Key considerations for substitutes include matching the 30000 mcd luminous intensity and white diffused lens.
Forward voltage and current are similar across candidates.
Standard 5mm through-hole package is widely available.
All candidates are significantly dimmer than the target.
No, a direct, pin-to-pin equivalent for the XL-502UGC with matching performance was not identified. All candidates require careful review.
No direct drop-in replacement found. Candidates offer a similar package but are significant downgrades in brightness.
The primary risk is a major reduction in luminous intensity, which could impact product visibility and user interface effectiveness.

| Feature / factor | XL-502UGC | XL-504UGD | NFD5408UGD | Alt 3 | Compatibility / risk |
|---|---|---|---|---|---|
| Package | 5mm (F5) | 5mm (F5) | 5mm | 5mm (F5) — Package dimensions match.; NFD5408UGD: Package dimensions are compatible. | |
| Luminous Intensity | 30000 mcd | 6000 mcd | 3000-9000 mcd | 6000 mcd / 3000-9000 mcd — Significantly lower brightness.; NFD5408UGD: Significantly lower brightness. | |
| Lens Type | White Diffused | Green Diffused | - | Green Diffused — Different lens color and diffusion. | |
| Voltage | 3.0 V | 3.0 V | 2.8-3.4 V | 3.0 V / 2.8-3.4 V — Forward voltage matches.; NFD5408UGD: Forward voltage range differs slightly. | |
| Viewing Angle | 30° | 30° | 20° | 30° / 20° — Viewing angle matches.; NFD5408UGD: Viewing angle is narrower. |
No ideal alternative was found. XL-504UGD has a matching package but is much dimmer. Both it and other candidates require design validation.
