C503B-ACS-CX0Y0251

Overview

The C503B-ACS-CX0Y0251 is a single-color amber LED from the Cree LED C503B series. It features a 5 mm (T-1 3/4) round lens with a dome shape and colorless, clear appearance. The component emits light at a dominant wavelength of 591 nm with a viewing angle of 30 degrees. Typical luminous intensity reaches 8200 mcd at a forward current of 20 mA. Electrical characteristics include a forward voltage of 2.1 V and a power rating of 130 mW. It supports an operating temperature range from -40°C to +100°C and utilizes through-hole mounting.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior high-temperature and high-moisture resistance for outdoor durability.
• Encapsulation resin contains UV inhibitors to minimize sunlight exposure effects and ensure stable light output over the LED's life.
• Round LED design offers superior light output for excellent readability in demanding environments.

Applications

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

Procurement Notes

Verify the specific suffix CX0Y0251 against official datasheets to confirm exact binning and packaging details. Note that Cree LED product portfolios may undergo changes; check for Not Recommended for New Design (NRND) status or obsolescence notices before finalizing procurement plans. Ensure compliance with RoHS requirements as specified in the manufacturer documentation.

Selection Notes

Select this component for applications requiring high visibility amber indicators with a 30-degree viewing angle. The 5 mm T-1 3/4 package suits standard through-hole PCB layouts. Consider the 2.1 V forward voltage and 20 mA drive current for circuit design. Verify thermal management capabilities given the 130 mW power rating and high-temperature operational limits.

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 (15, 23, and 30 degrees) and intensities. The ACS suffix typically denotes the 30-degree viewing angle variant within the amber color group, designed for general signaling and signage applications requiring broad visibility.

Replacement Considerations

Consult official Cree LED substitution guides for compatible alternatives. Cross-reference similar 5 mm amber LEDs with matching electrical parameters if direct replacement is required. Verify mechanical footprint compatibility for through-hole mounting when evaluating substitute components.
