C503B-WAN-CBABB231

Overview

The C503B-WAN-CBABB231 is a single-color amber LED from the Cree LED C503B series. It utilizes a T-1 3/4 (5 mm) through-hole package with a round dome lens. The component emits light at a dominant wavelength of 591 nm. Key electrical parameters include a forward current of 20 mA and a forward voltage of 2.1 V. The luminous intensity ranges from 3000 to 8200 mcd, providing high visibility. It operates within a temperature range of -40°C to +100°C and features a clear lens for optimal light transmission.

Feature Summary

• Constructed with advanced optical-grade epoxy resin containing UV inhibitors for superior resistance to high temperatures and moisture.
• Provides stable light output over long periods, ensuring excellent readability in direct sunlight.
• Features a 5 mm round dome lens design optimized for signal and illumination applications.

Applications

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

Procurement Notes

Verify the specific suffix CBABB231 against official datasheets to confirm binning and optical characteristics. Check lifecycle status as older Cree LED part numbers may be NRND or obsolete. Ensure RoHS compliance documentation is available for regulatory requirements. Confirm lead availability through authorized distributors due to potential supply chain variations for legacy components.

Selection Notes

Select this component for applications requiring high-brightness amber indication in outdoor environments. The 5 mm through-hole format suits standard PCB layouts. Consider the 30-degree viewing angle for directional signaling needs. Verify thermal management capabilities given the 100°C maximum operating temperature rating for harsh conditions.

Part Context

This part belongs to the Cree LED C503B family of 5-mm round LEDs. The series is designed for robust performance in outdoor signage and traffic signals. The C503B designation indicates the physical size and shape, while the suffix defines color and intensity bins. This family is known for durability and consistent photometric performance.

Replacement Considerations

Consult official Cree LED substitution guides for equivalent parts. Generic 5 mm amber LEDs may not match the specified luminous intensity or UV resistance. Verify pin compatibility and forward voltage tolerances before integrating alternative sources into existing designs.
