C503B-AAS-CA0C0342

Overview

The C503B-AAS-CA0C0342 is a single-color amber LED from the Cree C503B family, designed for high-intensity outdoor applications. It features a 5 mm (T-1 3/4) round lens with a clear surface and a narrow 15-degree viewing angle. The component operates at a typical forward voltage of 2.6 V with a maximum forward current of 50 mA and a power dissipation rating of 130 mW. It emits light at a dominant wavelength of 591 nm, providing superior luminous intensity ranging from 5860 to 23500 mcd. Constructed with optical-grade epoxy containing UV inhibitors, it ensures stable performance in harsh environments.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior resistance to high temperatures and moisture for reliable outdoor operation.
• Encapsulation resin includes UV inhibitors to minimize degradation from direct sunlight exposure, ensuring stable light output over the device's lifetime.
• Narrow 15-degree beam angle concentrates light output for excellent readability in long-distance signaling applications.

Applications

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

Procurement Notes

Verify the specific suffix CA0C0342 against the official C503B datasheet to confirm exact binning parameters such as luminous intensity and chromaticity coordinates. Ensure the procurement source is an authorized distributor to guarantee component authenticity and traceability. Confirm that the RoHS compliance status matches current regulatory requirements for the intended market. Check for any recent product change notifications regarding lead times or packaging variations.

Selection Notes

Select this component when high-intensity amber illumination is required for outdoor signage with strict visibility constraints. The 15-degree viewing angle makes it suitable for applications demanding focused light projection rather than wide dispersion. Consider the 50 mA maximum forward current and 130 mW power dissipation limits for thermal management design. This part is appropriate for general electronic signs but is not rated for automotive standards.

Part Context

This part belongs to the Cree C503B series of 5-mm Red and Amber Round LEDs. The series offers multiple variants distinguished by viewing angles (15, 23, and 30 degrees) and intensity bins. The C503B-AAS designation specifically indicates the amber color variant within the 15-degree beam family, optimized for high-brightness outdoor sign and signal applications requiring durable epoxy construction.

Replacement Considerations

Direct substitutes within the same family include other C503B-AAS variants with different intensity bins or suffixes, provided the electrical and mechanical specifications align. Cross-family replacements require careful evaluation of footprint compatibility and optical characteristics. Verify that any alternative maintains the required 15-degree viewing angle and amber wavelength for consistent visual performance.
