C503B-ACS-CX0Y0252

Overview

The C503B-ACS-CX0Y0252 is a 5-mm amber round through-hole LED from the Cree C503B family. It features a clear lens with a 30-degree viewing angle and emits at a typical dominant wavelength of 591 nm. The component operates with a forward voltage of 2.1 V at a test current of 20 mA, delivering a luminous intensity range of 3000 to 8200 mcd. Designed for outdoor durability, it utilizes UV-inhibited optical-grade epoxy encapsulation to ensure stable light output under high temperature and moisture conditions.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific suffix CX0Y0252 against official datasheets to confirm exact binning and packaging details. Confirm RoHS compliance status and check for any product change notices affecting lead frame or encapsulant materials. Ensure compatibility with existing PCB footprints for T-1 3/4 packages before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high readability in bright outdoor environments due to its superior light output. The 30-degree viewing angle offers a balance between beam focus and coverage. Verify that the 2.1 V forward voltage aligns with the system's drive circuitry and thermal management requirements for continuous operation.

Part Context

This part belongs to the C503B family of 5-mm round LEDs manufactured by Cree LED. The family includes red and amber variants with varying viewing angles (15, 23, and 30 degrees). These components are engineered specifically for outdoor signage and signal applications where environmental resilience and consistent photometric performance are critical design parameters.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires matching the 591 nm wavelength, 5-mm radial package, and 30-degree viewing angle specifications with other manufacturers' offerings.
