C503B-RCS-CYAYBAA1-030

Overview

The C503B-RCS-CYAYBAA1-030 is a single-color amber LED from the Cree LED C503B family. It features a T-1 3/4 (5 mm) round lens with a dome shape and clear colorless epoxy. The component operates at a dominant wavelength of 591 nm with a viewing angle of 30 degrees. Electrical characteristics include a forward voltage of 2.1 V at 20 mA, with a luminous intensity range of 3000 to 12000 mcd. It has a power rating of 130 mW and supports through-hole mounting in bulk packaging.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior resistance to high temperatures and moisture for outdoor durability.
• UV inhibitors are integrated into the resin to minimize degradation from direct sunlight exposure, ensuring stable light output over the product lifecycle.
• Designed for high readability in demanding environments with a 30-degree viewing angle and robust mechanical construction.

Applications

• Electronic Signs & Signals (ESS)
• Motorway Signs
• Variable-Message Sign (VMS)
• Advertising Signs

Procurement Notes

Verify the specific suffix CYAYBAA1-030 against the official datasheet to confirm exact binning and optical parameters. Check the lifecycle status as some variants in this series may be marked as Not Recommended for New Designs (NRND). Ensure compatibility with existing PCB footprints for T-1 3/4 packages before finalizing procurement decisions.

Selection Notes

Select this component when high visibility and environmental resilience are required for outdoor signage applications. The 30-degree beam angle offers a wider spread compared to narrower beam variants. Consider the 20 mA forward current requirement and thermal management needs given the 130 mW power rating for long-term reliability in varying ambient temperatures.

Part Context

This part belongs to the C503B-RCS/RCN/ACS/ACN family, which utilizes advanced optical-grade epoxy for enhanced durability. These LEDs are specifically engineered for outdoor sign and signal applications where resistance to high temperature, moisture, and UV exposure is critical for maintaining performance and longevity.

Replacement Considerations

Substitute parts must match the T-1 3/4 package, 591 nm amber wavelength, and 30-degree viewing angle. Verify that alternative components offer comparable luminous intensity ranges and RoHS compliance. Confirm that the replacement maintains similar forward voltage characteristics to ensure circuit compatibility.
