Overview
The C503B-ACS-CYAZA251-030 is a high-brightness amber LED from the Cree C503B series, designed for through-hole mounting in a radial 5mm package. It features a round lens with a domed top and emits light at a dominant wavelength of 591nm. The component operates with a typical forward voltage of 2.1V at a test current of 20mA. Luminous intensity ranges from 5860mcd to 10100mcd, providing superior light output for outdoor readability. The viewing angle is specified at 30 degrees, and the unit height is 8.60mm.
Feature Summary
- Utilizes advanced optical-grade epoxy encapsulation for superior high-temperature and high-moisture resistance.
- Contains UV inhibitors within the resin to minimize degradation from long-term direct sunlight exposure.
- Ensures stable light output over the operational life of the LED in harsh environmental conditions.
Applications
- Electronic Signs & Signals (ESS)
- Motorway Signs
- Variable-Message Sign (VMS) systems
Procurement Notes
Verify the specific suffix CYAZA251-030 against official datasheets to confirm luminous intensity binning and wavelength accuracy. Ensure compatibility with existing PCB footprints for 5mm radial components. Confirm RoHS compliance status as required by project specifications before finalizing procurement orders.
Selection Notes
Select this component when high visibility in outdoor environments is critical due to its robust UV-resistant construction. The 30-degree viewing angle offers a balance between beam focus and spread suitable for signage. Consider the 2.1V forward voltage drop for circuit design and ensure adequate thermal management despite the low power dissipation.
Part Context
This part belongs to the C503B family of 5mm round LEDs manufactured by Cree LED. The series includes variants with different viewing angles (15, 23, and 30 degrees) and colors. The 'ACS' designation typically indicates an amber color with a 30-degree viewing angle, while the suffix defines specific intensity bins and packaging details.
Replacement Considerations
Direct substitutes include other C503B-ACS variants with matching 30-degree viewing angles and similar luminous intensity ranges. Verify that any replacement maintains the same 5mm radial package dimensions and electrical characteristics to ensure mechanical and functional compatibility.
