Overview
The C503B-RCS-CYAYBAA2-030 is a red light-emitting diode from the Cree LED C503B series. It features a 5 mm (T-1 3/4) round lens with a 30-degree viewing angle. The component operates at a typical forward voltage of 2.1 V and has a maximum power dissipation of 130 mW. It emits light at a dominant wavelength of 624 nm with a luminous intensity range of 5860 to 23500 mcd. Designed for through-hole mounting, it utilizes advanced optical-grade epoxy for high temperature and moisture resistance.
Feature Summary
- Constructed with advanced optical-grade epoxy resin containing UV inhibitors for stable light output under direct sunlight exposure.
- Provides superior light output and excellent readability suitable for demanding outdoor environments.
- Encapsulation offers high resistance to elevated temperatures and high moisture conditions.
Applications
- Electronic Signs & Signals (ESS)
- Motorway Signs
- Variable-Message Sign (VMS)
- Advertising Signs
Procurement Notes
Verify the specific suffix codes against official datasheets to confirm exact luminous intensity bins and wavelength tolerances. Confirm RoHS compliance status and check for any Product Change Notifications regarding packaging or material updates before finalizing procurement specifications.
Selection Notes
Select this component for applications requiring high-brightness red indicators in outdoor signage. Ensure circuit design accommodates the 2.1 V forward voltage and 130 mW power rating. Verify that the 30-degree viewing angle aligns with the required beam spread for the specific sign configuration.
Part Context
This part belongs to the C503B family of 5 mm LEDs designed for harsh outdoor conditions. The series is characterized by its durability and high luminous efficiency, making it a standard choice for traffic and advertising displays where long-term reliability and visibility are critical performance factors.
Replacement Considerations
Cross-reference with other C503B-RCS variants for different intensity bins. Verify mechanical compatibility with existing PCB footprints when substituting with similar 5 mm T-1 3/4 packages from other manufacturers.
FAQ
What is the recommended operating current for this LED?
The datasheet specifies a test current of 20 mA for measuring luminous intensity, with a maximum continuous forward current limit defined by the 130 mW power dissipation rating.
How does the UV inhibitor affect longevity?
The encapsulation resin contains UV inhibitors that minimize degradation effects from long-term exposure to direct sunlight, ensuring stable light output over the operational life of the LED.
