C503B-BCN-CU0W0451-030

Overview

The C503B-BCN-CU0W0451-030 is a blue light-emitting diode from the Cree LED C503B series, housed in a 5 mm (T-1 3/4) radial through-hole package. It features a clear lens and emits at a dominant wavelength of 470 nm with a 30-degree viewing angle. The component operates with a forward voltage of approximately 4 V and a maximum power dissipation of 120 mW. It complies with RoHS standards and is designed for high reliability in outdoor environments.

Feature Summary

• Advanced optical-grade epoxy construction provides superior resistance to high temperatures and moisture for dependable performance in outdoor signal applications.
• Offers extremely stable light output over long periods, ensuring excellent readability in sunlight for electronic signs and variable-message displays.

Applications

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

Procurement Notes

Verify the specific suffix configuration against official Cree documentation to ensure alignment with required luminous intensity and binning specifications. Confirm that the 5 mm T-1 3/4 through-hole package matches the target PCB footprint and assembly requirements. Check for RoHS compliance status and lead-free certification if mandated by project regulations.

Selection Notes

Select this component when a 30-degree viewing angle is required for blue illumination in signage applications. Ensure the circuit design accommodates the 4 V forward voltage drop and limits current to stay within the 120 mW power dissipation rating. Consider the 5 mm round package dimensions for mechanical clearance and mounting constraints.

Part Context

This part belongs to the Cree C503B family of 5-mm Blue and Green Round LEDs. The series is engineered for high-brightness visibility in daylight conditions. The 'BCN' designation typically indicates the blue color variant with a 30-degree viewing angle, distinguishing it from the narrower 15-degree beam options available in the same product line.

Replacement Considerations

Cross-reference with other C503B-BCN variants for different intensity bins or packaging formats. Verify electrical compatibility before substituting with generic 5 mm blue LEDs, as forward voltage and luminous intensity may differ significantly.
