C503B-ACS-CW0Y0252

Overview

The C503B-ACS-CW0Y0252 is a single-color amber LED from the Cree LED C503B series, designed for through-hole mounting in a T-1 3/4 (5 mm) package. It features a clear dome lens and emits at a dominant wavelength of 591 nm. The component operates with a forward current of 20 mA and a typical forward voltage of 2.1 V, with a power rating of 130 mW. It provides a luminous intensity of 8090 mcd and a viewing angle of 30 degrees. The device functions within a temperature range of -40°C to +100°C.

Feature Summary

• Optical-grade epoxy encapsulation with UV inhibitors for high-temperature and moisture resistance
• Clear dome lens design optimized for superior light output and readability
• Stable light output performance maintained over long-term exposure

Applications

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

Procurement Notes

Verify the specific suffix CW0Y0252 against official Cree LED documentation to confirm exact binning and optical characteristics. Ensure compatibility with existing PCB footprints for the T-1 3/4 package. Confirm RoHS compliance status for the specific manufacturing batch prior to integration into final assemblies.

Selection Notes

Select this component for applications requiring high-brightness amber indication with a 30-degree beam angle. The 5 mm round form factor ensures mechanical compatibility with standard through-hole layouts. Consider the 2.1 V forward voltage drop when designing drive circuits to ensure proper current limiting and thermal management.

Part Context

This part belongs to the C503B family of 5-mm Red and Amber Round LEDs. The series is engineered for outdoor signage and signal applications where durability and visibility are critical. The ACS designation typically indicates a specific intensity bin within the 30-degree viewing angle product line.

Replacement Considerations

Cross-reference with other C503B variants such as C503B-ACN or C503B-ACS with different suffixes only if optical intensity and wavelength tolerances align with system requirements.
