Procurement Notes

Verify the specific suffix against official Cree documentation to confirm exact binning and optical parameters. Ensure compatibility with existing PCB footprints and thermal management requirements. Confirm RoHS compliance status directly with the manufacturer or authorized distributor before finalizing procurement decisions.

Selection Notes

Select this component when high visibility in direct sunlight is required due to its superior light output and UV-resistant encapsulation. The 15-degree beam angle makes it suitable for applications needing focused illumination. Consider the 4 V forward voltage drop when designing the driving circuitry to ensure proper current limiting and power dissipation within the 120 mW limit.

Part Context

This part belongs to the Cree 5-mm Round LED family, which includes variants in red, amber, blue, green, and white. These LEDs are engineered for outdoor sign and signal applications where durability and consistent performance under harsh environmental conditions are critical. The family shares common mechanical dimensions but varies in optical properties based on the semiconductor material used.

Replacement Considerations

Direct substitutes within the same Cree 5mm family include C503B-WAS (30-degree view) or other color variants like C503B-BAN. Cross-brand replacements require verification of pinout, forward voltage, and luminous intensity to maintain system performance without redesigning the host circuit board.

FAQ

What is the typical dominant wavelength for the C503B-WAN?

The datasheet specifies a typical color temperature of 9000 K for the cool white variant, rather than a single dominant wavelength value.

Is the C503B-WAN suitable for outdoor automotive use?

While the LED has high moisture and temperature resistance, the provided documentation does not explicitly certify it for automotive standards; it is primarily listed for general electronic signs and signals.
