C503B-RAN-CA0C0AA2

Overview

The C503B-RAN-CA0C0AA2 is a single-color red LED from the Cree LED series, designed for through-hole mounting in a 5 mm (T-1 3/4) round package. It features a clear lens with a 15-degree viewing angle and emits at a dominant wavelength of 624 nm. The component operates with a typical forward voltage of 2.1 V at a test current of 20 mA, delivering a luminous intensity range of 22,450 to 23,500 mcd. It complies with RoHS standards and supports standard packaging formats.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior resistance to high temperatures and moisture for outdoor durability.
• UV inhibitors integrated into the resin minimize degradation effects from long-term direct sunlight exposure.
• Stable light output performance maintained over the operational life of the LED.

Applications

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

Procurement Notes

Verify the specific suffix CA0C0AA2 against official manufacturer documentation to confirm exact binning and packaging configuration. Ensure compatibility with existing PCB layouts for the 5 mm radial leaded form factor. Confirm RoHS compliance status via the latest datasheet revision before finalizing procurement specifications.

Selection Notes

Select this component when high visibility in bright ambient conditions is required due to its high luminous intensity. The 15-degree beam angle suits applications needing focused illumination. Verify thermal management requirements as the device dissipates power during operation. Ensure the forward voltage characteristics align with the driving circuit design parameters.

Part Context

This part belongs to the C503B family of 5 mm round LEDs manufactured by Cree LED. The series includes various colors and beam angles optimized for readability in outdoor environments. The RAN designation indicates a red color variant with a narrow 15-degree viewing angle, distinguishing it from wider-angle or different-color counterparts within the same product line.

Replacement Considerations

Cross-reference with other C503B-RAN variants for identical electrical and mechanical properties. Check for updated suffixes indicating revised packaging or minor parameter adjustments. Ensure substitute parts maintain the same 5 mm T-1 3/4 package dimensions and lead spacing for direct board replacement.
