C503B-RBN-CY0Z0AA2

Overview

C503B-RBN-CY0Z0AA2 is a red through-hole LED from the Cree C503B series, featuring a 5 mm round lens with a clear dome. It emits at a dominant wavelength of 624 nm with a typical forward voltage of 2.1 V at 20 mA test current. The component offers a luminous intensity range of 3000 to 12000 mcd and a viewing angle of 23 degrees. Constructed with optical-grade epoxy containing UV inhibitors, it ensures high-temperature and moisture resistance for stable outdoor performance.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior resistance to high temperatures and moisture.
• Encapsulation resin includes UV inhibitors to minimize degradation from direct sunlight exposure.
• Ensures stable light output over the operational life in demanding outdoor environments.

Applications

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

Procurement Notes

Verify the specific suffix against official Cree documentation to confirm exact binning parameters such as luminous intensity and wavelength. Ensure compatibility with RoHS standards if required by the target application. Confirm package type and lead configuration match the design requirements before finalizing procurement.

Selection Notes

Select this component for applications requiring high visibility and durability in outdoor conditions. The 23-degree viewing angle balances wide coverage with focused intensity. Consider the thermal management capabilities of the optical epoxy for long-term reliability in exposed installations.

Part Context

The C503B-RBN-CY0Z0AA2 belongs to the Cree 5-mm Red and Amber Round LED family. This series is engineered specifically for outdoor readability, utilizing robust materials to withstand environmental stressors while maintaining consistent optical performance across various operating conditions.

Replacement Considerations

Cross-reference with other C503B variants sharing the same 23-degree viewing angle and 5 mm form factor. Verify electrical characteristics and mechanical dimensions to ensure functional equivalence without redesigning the host circuit or enclosure.
