C5SMF-RJS-CT34QBB1

Overview

The C5SMF-RJS-CT34QBB1 is a single-color red LED from the Screen Master family, manufactured by Cree LED. It utilizes a through-hole mounting style within a T-1 3/4 (5 mm) oval package. The component emits light at a primary wavelength of 624 nm with a forward voltage of 2.6 V. It features an oval lens shape and provides a luminous intensity of 2.6 cd. Designed for high-brightness applications, it operates within a temperature range of -40°C to +95°C.

Feature Summary

• Oval-shaped radiation pattern optimized for wide viewing angles in signage
• High luminous intensity suitable for variable-message displays
• Through-hole construction for standard PCB integration

Applications

• Variable-message signs
• Passenger-information signs
• Public transportation display systems

Procurement Notes

Verify the specific suffix CT34QBB1 against official Cree documentation to confirm binning and optical characteristics. Ensure compatibility with existing thermal management designs given the 95°C maximum operating temperature. Cross-reference datasheet revisions to confirm current production status and availability constraints before finalizing procurement plans.

Selection Notes

Select this component when wide-angle visibility is required for red indicator applications. The oval lens design supports broader horizontal dispersion compared to round LEDs. Consider the 2.6 V forward voltage drop for circuit power budgeting. Verify that the through-hole form factor aligns with the target assembly manufacturing processes and mechanical clearance requirements.

Part Context

This part belongs to the Screen Master C5SMF series, which focuses on high-performance indicators for large-format displays. The series emphasizes brightness and viewing angle consistency. It represents a legacy through-hole solution often used in established infrastructure where surface-mount alternatives may not provide sufficient angular coverage or mechanical robustness.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Evaluate other C5SMF variants with different color codes or intensities if functional equivalence allows. Consult manufacturer obsolescence notices for potential end-of-life transitions.
