C503B-AAS-CY0C0252

Overview

The C503B-AAS-CY0C0252 is a single-color amber LED from the Cree LED C503B series. It features a 5mm (T-1 3/4) round package with a domed top lens and clear colorless appearance. The component emits light at a dominant wavelength of 591 nm. Typical forward voltage is 2.1 V at a test current of 20 mA, with a luminous intensity of 5860 mcd. It has a viewing angle of 15 degrees and supports a maximum forward current of 50 mA. The device is RoHS compliant and designed for through-hole mounting.

Feature Summary

• Utilizes advanced optical-grade epoxy encapsulation for superior high-temperature and high-moisture resistance in outdoor environments.
• Encapsulation resin contains UV inhibitors to minimize degradation effects from long-term direct sunlight exposure.
• Provides stable light output over the operational life of the LED under harsh conditions.

Applications

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

Procurement Notes

Verify the specific suffix CY0C0252 against official Cree datasheets to confirm exact binning and optical characteristics. Ensure the procurement channel provides original manufacturer documentation. Confirm RoHS compliance status matches current regulatory requirements. Check for any recent Product Change Notices affecting packaging or material composition before finalizing orders.

Selection Notes

Select this component when a narrow 15-degree viewing angle is required for focused visibility in signage applications. The amber color and 591 nm wavelength are suitable for standard signal indications. Consider the 5mm through-hole package for compatibility with existing PCB layouts. Evaluate the 5860 mcd intensity against ambient lighting conditions to ensure adequate readability.

Part Context

This part belongs to the C503B family of 5-mm Red and Amber Round LEDs. The family includes variants with different viewing angles such as 23 degrees and 30 degrees. The AAS designation specifically indicates the 15-degree viewing angle variant within the amber color group. These lamps are engineered for outdoor sign and signal applications requiring high durability.

Replacement Considerations

Cross-reference other C503B-Axx variants if different viewing angles are acceptable. Verify pinout and mechanical dimensions match the target footprint. Ensure electrical parameters like forward voltage and current ratings are compatible with the driving circuitry before substituting.
