C503C-ACN-CYAZA251

Overview

The C503C-ACN-CYAZA251 is a single-color amber LED from the Cree LED C503C family. It features a 5 mm round T-1 3/4 package with a clear dome lens and through-hole radial mounting. The component emits light at a dominant wavelength of 591 nm. Key electrical parameters include a forward voltage of 2.1 V at a test current of 20 mA, with a power rating of 130 mW. It offers a viewing angle of 30 degrees and operates within a temperature range of -40°C to +100°C.

Feature Summary

• Constructed with advanced optical-grade epoxy for superior high-temperature and high-moisture resistance.
• Encapsulation resin contains UV inhibitors to minimize sunlight exposure effects and ensure stable light output.
• Provides superior light output designed for excellent readability in outdoor applications.

Applications

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

Procurement Notes

Verify the specific suffix CYAZA251 against official datasheets to confirm binning and optical characteristics. Confirm RoHS compliance status as required by project specifications. Check for end-of-life or not-recommended-for-new-designations prior to final procurement decisions.

Selection Notes

Select this component for applications requiring high visibility in direct sunlight due to its UV-resistant encapsulation. Ensure circuit design accommodates the 2.1 V forward voltage drop. Verify that the 30-degree viewing angle aligns with the required beam spread for the target installation environment.

Part Context

This part belongs to the Cree LED C503B/C503C series of 5-mm round LEDs. These lamps are engineered for demanding outdoor environments where durability and consistent luminous intensity are critical. The series utilizes specialized epoxy materials to withstand harsh weather conditions while maintaining optical performance over the product's lifespan.

Replacement Considerations

Consult official substitution guides for compatible alternatives within the same optical class. Verify mechanical footprint compatibility for the 5 mm T-1 3/4 package. Ensure replacement parts meet identical environmental resistance standards for outdoor sign applications.
