C503B-WAN-CBBDB231

Overview

The C503B-WAN-CBBDB231 is a 5mm round LED from the Cree LED family, designed for high-visibility applications. It features a 23-degree viewing angle and emits cool white light with a typical color temperature of 9000K. The component utilizes advanced optical-grade epoxy to ensure superior resistance to high temperatures and moisture, maintaining stable light output over long periods. This construction minimizes degradation effects from direct sunlight exposure, making it suitable for demanding outdoor environments where reliable performance and excellent readability are required.

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 extremely stable light output over the operational life of the LED

Applications

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

Procurement Notes

Verify the specific suffix against official Cree documentation to confirm the exact viewing angle and luminous intensity binning. Ensure the ordering code matches the required 23-degree beam characteristic. Confirm RoHS compliance status through the manufacturer's current datasheet rather than distributor listings.

Selection Notes

Select this component when a wider beam spread than standard 15-degree LEDs is required for sign visibility. The 23-degree angle balances intensity and coverage for medium-distance reading. Consider the cool white color temperature for maximum contrast in daylight conditions compared to warmer tones.

Part Context

This part belongs to the Cree 5-mm Round LED family, which includes red, amber, blue, green, and white variants. These components share a common T-1 3/4 (5mm) package form factor but differ in dominant wavelength, luminous intensity ranges, and viewing angles based on their specific suffix designations.

Replacement Considerations

Direct substitutes within the same family include other 5mm round LEDs with similar 23-degree viewing angles, such as C503B-RBS or C503B-AAS, provided the color and intensity requirements match. Verify electrical parameters before substitution.
