C503B-ACS-CX0Y0341

Overview

The C503B-ACS-CX0Y0341 is a single-color amber LED from the C503B series, manufactured by Cree LED. It features a 5 mm (T-1 3/4) round through-hole package with a clear dome lens. The component emits at a dominant wavelength of 591 nm and provides a luminous intensity range of 3000 to 8200 mcd. Electrical characteristics include a forward voltage of 2.1 V and a forward current rating of 20 mA, with a power dissipation of 130 mW. It offers a 30-degree viewing angle and operates within a temperature range of -40°C to +100°C.

Feature Summary

• Advanced optical-grade epoxy encapsulation for superior high-temperature and moisture resistance
• UV inhibitors in the resin minimize degradation from direct sunlight exposure
• Stable light output maintained over the operational life of the LED

Applications

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

Procurement Notes

Verify the specific suffix configuration against official datasheets to ensure correct binning and optical parameters. Confirm RoHS compliance status and packaging type prior to ordering. Check for end-of-life notifications or recommended replacement parts due to potential obsolescence. Validate lead times and minimum order quantities with authorized distributors. Ensure storage conditions meet specified humidity sensitivity levels.

Selection Notes

Select this component for applications requiring high visibility in outdoor environments. The 30-degree viewing angle balances beam spread with intensity. Consider the thermal management requirements given the 130 mW power rating. Verify mechanical fit for the T-1 3/4 package in existing PCB layouts. Evaluate cost-effectiveness against alternative amber LEDs with similar luminous intensity specifications.

Part Context

This part belongs to the C503B family of 5-mm round LEDs designed for signage and signal applications. The series includes red and amber variants with different viewing angles (15, 23, and 30 degrees). The C503B-ACS variant specifically denotes an amber LED with a 30-degree viewing angle. These components are engineered for durability in harsh environmental conditions.

Replacement Considerations

Consult official Cree LED documentation for confirmed substitute part numbers. Generic cross-references may not match optical or electrical specifications. Verify compatibility if replacing obsolete stock.
