C503B-ACS-CYAZA252-030

Overview

The C503B-ACS-CYAZA252-030 is a single-color amber LED from the Cree C503B series, designed for through-hole mounting in a 5 mm (T-1 3/4) radial package. It features a clear, round lens with a domed top and emits light at a dominant wavelength of 591 nm. The component operates with a typical forward voltage of 2.1 V and a test current of 20 mA, delivering a luminous intensity of 8090 mcd. It has a viewing angle of 30 degrees and a maximum power dissipation of 130 mW.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior resistance to high temperatures and moisture for outdoor durability.
• Encapsulation resin contains UV inhibitors to minimize degradation from direct sunlight exposure, ensuring stable light output over the product life.
• Round lens design with a clear, colorless finish supports excellent readability in electronic sign and signal applications.

Applications

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

Procurement Notes

Verify the specific suffix CYAZA252 against official Cree documentation to confirm exact luminous intensity binning and wavelength tolerances. Ensure the ordering part number matches the required packaging format, as variations exist between bulk, tape, and reel configurations. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to procurement.

Selection Notes

Select this component for applications requiring a 30-degree viewing angle and moderate luminous intensity in the amber spectrum. The 5 mm T-1 3/4 package is suitable for standard PCB layouts. Consider the 2.1 V forward voltage drop for circuit design. Verify environmental ratings if deployment involves extreme temperature fluctuations or high humidity conditions beyond standard indoor use.

Part Context

This part belongs to the C503B family of 5 mm round LEDs manufactured by Cree LED. The series includes red and amber variants with different beam angles (15, 23, and 30 degrees). The ACS designation typically indicates the 30-degree viewing angle variant within the amber category, utilizing advanced epoxy technology for enhanced environmental stability compared to standard components.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Cross-reference with other Cree C503B-ACS variants only if electrical parameters and mechanical dimensions match exactly. Consult official Cree databases for potential end-of-life notifications or recommended upgrades.
