C503B-AAS-CA0C0342-015

Overview

The C503B-AAS-CA0C0342-015 is a single-color amber LED from the Cree C503B series, housed in a 5 mm (T-1 3/4) through-hole package. It features a round lens with a clear surface and emits light at a typical dominant wavelength of 591 nm. The component provides a luminous intensity range of 5860 to 23500 mcd with a viewing angle of 15 degrees. Electrical characteristics include a maximum forward current of 20 mA, a forward voltage of 2.1 V, and a maximum power dissipation of 130 mW.

Feature Summary

• Constructed with advanced optical-grade epoxy for superior high-temperature and high-moisture resistance.
• Encapsulation resin contains UV inhibitors to minimize effects of long-term direct sunlight exposure.
• Ensures stable light output over the life of the LED in outdoor sign and signal applications.

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 lens shape and electrical parameters. Confirm RoHS compliance status and check for any discontinuation notices or recommended new designations prior to procurement. Cross-reference distributor listings with manufacturer documentation to validate authenticity and exact part specifications.

Selection Notes

Select this component for applications requiring high visibility in bright outdoor environments due to its UV-resistant construction. The 15-degree viewing angle concentrates light for long-distance readability. Ensure circuit design accommodates the 2.1 V forward voltage and 20 mA maximum forward current limits to maintain performance and longevity.

Part Context

This part belongs to the Cree C503B family of 5-mm Red and Amber Round LEDs. The series is engineered for excellent readability in demanding outdoor conditions. The AAS designation indicates a specific intensity bin within the 15-degree viewing angle category, offering high luminous intensity for critical signaling tasks.

Replacement Considerations

Consult the official C503B datasheet for cross-referencing similar intensity bins or alternative viewing angles within the same family. Verify mechanical compatibility and electrical ratings before substituting with other manufacturers' 5 mm through-hole amber LEDs.
