C503B-ACN-CYAZA251-030

Overview

The C503B-ACN-CYAZA251-030 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, colorless lens with a domed shape and emits light at a dominant wavelength of 591 nm. The component operates with a typical forward voltage of 2.1 V at a test current of 20 mA, achieving a luminous intensity range of 3000 to 8200 mcd. It has a standard viewing angle of 30 degrees and a maximum power dissipation of 130 mW. The device is RoHS compliant and suitable for outdoor sign and signal applications.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior resistance to high temperatures and moisture for reliable outdoor performance.
• Encapsulation resin includes UV inhibitors to minimize degradation from direct sunlight exposure, ensuring stable light output over the component's life.
• Radial 5 mm T-1 3/4 package design facilitates easy through-hole integration into electronic assemblies.

Applications

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

Procurement Notes

Verify the specific suffix CYAZA251-030 against official Cree documentation, as this exact string may represent a custom or distributor-specific variant not listed in standard public datasheets. Confirm availability status and lead times directly with authorized distributors, as stock levels fluctuate. Ensure compliance with RoHS standards and check for any recent Product Change Notifications (PCNs) regarding packaging or material updates before finalizing procurement orders.

Selection Notes

Select this component when a 5 mm amber LED with a 30-degree viewing angle is required for general indication or signage. Consider the 2.1 V forward voltage and 20 mA operating current for circuit design. Evaluate the 3000–8200 mcd intensity range against visibility requirements. Compare with other C503B variants like ACN-CX0Y0251 if different intensity or lens shapes are needed. Ensure the through-hole form factor matches the PCB layout constraints.

Part Context

This part belongs to the Cree C503B family of 5-mm Red and Amber Round LEDs. The family offers multiple viewing angles (15, 23, and 30 degrees) and intensity grades. The 'ACN' designation typically indicates an amber LED with a 30-degree viewing angle and a specific intensity bin. These LEDs are engineered for durability in harsh environments, utilizing advanced epoxy materials to maintain performance under extreme weather conditions common in outdoor signaling applications.

Replacement Considerations

Publicly confirmed parameter-equivalent substitutes include C503B-ACS-CY0Z0251 and C503B-ACS-CY0Z0251-030. Verify that these alternatives match the required 30-degree viewing angle and amber color specifications. Check for any differences in luminous intensity bins or forward voltage tolerances between the original part and potential replacements to ensure functional compatibility in the target application.
