Needs validationlow risk
A strong alternative with matching color, voltage, current, and brightness in a similar 5mm through-hole package.
Best Alternatives to XL-504UYD
XL-504UYD is a standard 5mm yellow through-hole LED used for indication. Finding a substitute requires matching its color, 2.0V forward voltage, and 600mcd brightness in a T-1 3/4 package.
AI replacement insight
Electrical risklow
Forward voltage and current match.
Package risklow
Packages are equivalent 5mm through-hole types, but verify mechanical drawings for precise fit.
Can it be replaced directly?
Direct replacement for XL-504UYD should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
XL-502UYD is the most promising direct replacement, matching all key electrical and optical specifications.
Main risk
The primary risk is subtle differences in optical properties like lens diffusion or exact color binning, which can affect visual consistency.
