C503B-RBN-CX0Y0AA2

Overview

The C503B-RBN-CX0Y0AA2 is a red, single-color LED from the Cree LED family. It features a 5mm round, clear dome lens with a 23-degree viewing angle. The component operates at a typical forward voltage of 2.1V and a test current of 20mA. It emits light at a dominant wavelength of 624nm with a luminous intensity range of 3000 to 12000 mcd. Designed for through-hole radial mounting, it has a maximum height of 8.60mm.

Feature Summary

• Advanced optical-grade epoxy encapsulation provides superior high-temperature and high-moisture resistance.
• Encapsulation resin contains UV inhibitors to minimize effects of long-term direct sunlight exposure.
• Ensures stable light output over the life of the LED in outdoor sign and signal applications.

Applications

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

Procurement Notes

Verify the specific suffix CX0Y0AA2 against official datasheets to confirm the exact luminous intensity bin within the 3000-12000 mcd range. Ensure the package matches the 5mm radial through-hole specification. Confirm RoHS compliance status as required by project standards before finalizing procurement orders.

Selection Notes

Select this component for applications requiring high readability in outdoor environments due to its UV-resistant epoxy construction. The 23-degree beam angle offers a balance between focused visibility and wider coverage compared to narrower or wider alternatives. Ensure circuit design accommodates the 2.1V forward voltage drop at standard operating currents.

Part Context

This part belongs to the C503B series of 5mm Red and Amber Round LEDs manufactured by Cree LED. The series includes variants with different viewing angles (15, 23, and 30 degrees) and intensities. The RBN designation specifically indicates the red color variant with a 23-degree viewing angle, positioned within the broader family of high-performance indicator lamps.
