C503B-BCS-CU0W0451-030

Overview

The C503B-BCS-CU0W0451-030 is a blue light-emitting diode from the Cree LED 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 451 nm. The component has a forward voltage of 4 V and a maximum power dissipation of 120 mW. It offers a viewing angle of 30 degrees and a luminous intensity range of 2130 to 12000 mcd.

Feature Summary

• Provides superior light output for excellent readability in sunlight
• Ensures dependable performance with extremely stable light output over long periods
• Constructed with advanced optical-grade epoxy for high temperature and moisture resistance

Applications

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

Procurement Notes

Verify the specific suffix CU0W0451-030 against official Cree datasheets to confirm exact binning and availability, as distributor listings may vary. Ensure compliance with RoHS standards and check for any recent product change notices affecting packaging or labeling before procurement.

Selection Notes

Select this component for applications requiring high visibility in direct sunlight due to its superior light output. The 30-degree viewing angle provides a wider beam than narrow-angle variants. Ensure circuit design accommodates the 4 V forward voltage and 120 mW power dissipation limits for reliable operation.

Part Context

This part belongs to the C503B family of 5-mm Blue and Green Round LEDs. The 'BCS' designation indicates a blue color variant with a 30-degree viewing angle. These LEDs are designed for outdoor signal and sign applications where durability and brightness are critical.

Replacement Considerations

Direct substitutes within the same family include C503B-BAS, C503B-BAN, C503B-GAS, and C503B-GAN for 15-degree angles, or C503B-BCN, C503B-GCS, and C503B-GCN for 30-degree angles. Verify wavelength and intensity bins match application requirements.
