C503B-RAS-CA0B0AA1

Overview

The C503B-RAS-CA0B0AA1 is a single-color amber LED from the Cree LED C503B series, designed for through-hole mounting in a 5 mm (T-1 3/4) round package. It features a clear colorless lens with a 15-degree viewing angle and emits light at a dominant wavelength of 624 nm. The component operates with a forward voltage of approximately 2.1 V and a maximum forward current of 20 mA, dissipating up to 130 mW. Luminous intensity ranges from 5860 to 23500 mcd. It complies with RoHS standards and includes UV inhibitors for outdoor stability.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior high-temperature and high-moisture resistance for reliable performance in harsh environments.
• Encapsulation resin contains UV inhibitors to minimize degradation effects from long-term direct sunlight exposure, ensuring stable light output over the product lifecycle.
• Optimized for excellent readability in outdoor applications due to superior light output characteristics inherent to the round LED design.

Applications

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

Procurement Notes

Verify the specific suffix CA0B0AA1 against official Cree documentation to confirm exact luminous intensity binning and wavelength tolerances. Ensure the procurement channel sources genuine components to maintain RoHS compliance and material integrity. Check for any end-of-life notices or recommended new designations that may affect long-term supply chain stability for this specific variant.

Selection Notes

Select this component when a narrow 15-degree beam angle is required for focused visibility in outdoor signage. The amber color at 624 nm offers high contrast for signal applications. Consider the 20 mA forward current limit and 130 mW power dissipation rating for thermal management in dense arrays. Verify compatibility with existing through-hole PCB layouts requiring 5 mm T-1 3/4 spacing.

Part Context

This part belongs to the C503B family of 5-mm Red and Amber Round LEDs, which are engineered for outdoor sign and signal applications. The RAS designation indicates a 15-degree viewing angle configuration within the series. These LEDs utilize advanced materials to withstand environmental stressors, distinguishing them from standard indoor indicators by their enhanced durability and optical consistency under prolonged sun exposure.

Replacement Considerations
