C503B-BAS-CZ0A0451

Overview

The C503B-BAS-CZ0A0451 is a blue single-color LED from the Cree C503B series, housed in a 5 mm (T-1 3/4) radial through-hole package. It features a clear lens with a 15-degree viewing angle and emits at a dominant wavelength of 470 nm. Typical luminous intensity ranges from 5860 to 32900 mcd. The component operates with a forward voltage of 3.2 V at 20 mA, with a maximum rating of 4 V and 30 mA. Power dissipation is rated at 120 mW, and it complies with RoHS standards.

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 CZ0A0451 against official Cree documentation to confirm exact binning and lens specifications. Ensure compatibility with existing PCB footprints for 5 mm T-1 3/4 packages. Confirm RoHS compliance status for current production runs. Cross-reference datasheet revisions to validate electrical parameters before integration into final designs.

Selection Notes

Select this component for applications requiring high-intensity blue illumination with a narrow 15-degree beam angle. The 5 mm round package suits standard through-hole mounting processes. Consider the 120 mW power rating for thermal management in enclosed assemblies. Verify that the 3.2 V forward voltage aligns with the driving circuit's supply constraints.

Part Context

This part belongs to the Cree C503B family of 5-mm blue and green round LEDs. The series is designed for outdoor signal and sign applications due to its robust epoxy construction. It offers a balance of high luminous intensity and wide viewing angles, available in both 15-degree and 30-degree variants depending on the specific model suffix.

Replacement Considerations

Direct substitutes within the same family include C503B-BAN-CZ0A0451 for higher intensity or C503B-BCS-CZ0A0451 for a wider 30-degree view. Green alternatives like C503B-GAS are available if color change is acceptable. Always verify pinout and mechanical dimensions match when swapping between different lens styles or intensities.
