C503B-RAS-CA0C0AA1

Overview

The C503B-RAS-CA0C0AA1 is a single-color red LED from the Cree LED family, housed in a 5 mm (T-1 3/4) through-hole package. It features a round lens with a 15-degree viewing angle and emits at a dominant wavelength of 624 nm. The component operates with a forward current of 20 mA and a forward voltage of approximately 2.1 V to 2.6 V, dissipating up to 130 mW. It utilizes advanced optical-grade epoxy for high temperature and moisture resistance.

Feature Summary

• Constructed with advanced optical-grade epoxy resin containing UV inhibitors for stable light output under direct sunlight exposure.
• Provides superior light output and excellent readability specifically designed for outdoor sign and signal applications.
• Encapsulation ensures high resistance to high-temperature and high-moisture environments typical of outdoor conditions.

Applications

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

Procurement Notes

Verify the specific suffix CA0C0AA1 against official Cree LED documentation to confirm exact luminous intensity and wavelength binning. Ensure the procurement channel provides valid RoHS compliance certificates. Cross-reference the manufacturer part number with authorized distributor lists to avoid counterfeit components. Confirm lead times and packaging formats directly with the supplier prior to order placement.

Selection Notes

Select this component for applications requiring a narrow 15-degree beam angle to focus red light over distance. Consider the 5 mm T-1 3/4 form factor for standard through-hole mounting constraints. Evaluate the environmental durability provided by the UV-inhibited epoxy for long-term outdoor deployment. Compare luminous intensity requirements against the specified range for the RAS series variant.

Part Context

This part belongs to the C503B series of 5-mm Red and Amber Round LEDs manufactured by Cree LED. The series is engineered for robust performance in harsh outdoor environments. The RAS designation indicates a specific viewing angle and color configuration within the broader product line, emphasizing high visibility for traffic and advertising signage.

Replacement Considerations

Consult official Cree LED substitution guides for equivalent parts with matching electrical characteristics and mechanical dimensions. Verify that any alternative component maintains the required 15-degree viewing angle and 5 mm package size. Ensure compatibility with existing PCB layouts and thermal management strategies before implementing a substitute.
