C5SMF-BJS-CS24Q4T1

Overview

The C5SMF-BJS-CS24Q4T1 is a single-color blue oval LED from the Screen Master series by Cree LED. It utilizes a T-1 3/4 (5 mm) through-hole package with an oval lens measuring 5.1 mm x 3.7 mm. The component emits light at a peak wavelength of 470 nm with a tinted blue lens. Electrical characteristics include a forward voltage of 3.4 V and a forward current rating of 20 mA, resulting in a power rating of 140 mW. The optical intensity is specified at 1100 mcd.

Feature Summary

• Features an oval-shaped radiation pattern designed for high visibility in signage applications.
• Constructed with a tinted blue lens to enhance visual contrast and signal clarity.
• Utilizes a standard radial through-hole mounting style for reliable PCB integration.

Applications

• Variable-message signs
• Passenger-information signs
• General indicator lighting

Procurement Notes

This specific part number is officially listed as obsolete and no longer manufactured by Cree LED. Verification of availability should focus on identifying parametric equivalents or alternative components within the same product family that meet the required electrical and mechanical specifications. Direct procurement of this exact SKU is not supported by standard supply channels.

Selection Notes

Engineers selecting this component must account for its end-of-life status. Selection criteria should prioritize matching the 470 nm wavelength, 5 mm oval form factor, and 3.4 V forward voltage requirements. Alternative parts from the C5SMF series should be evaluated based on identical pin configurations and luminous intensity to ensure seamless replacement in existing designs without re-engineering.

Part Context

The C5SMF-BJS-CS24Q4T1 belongs to the Screen Master series, which specializes in oval LEDs optimized for readability in dynamic display environments. This series distinguishes itself through specific optical shaping that directs light efficiently toward viewers. The component represents a legacy solution for analog and early digital signage systems requiring distinct blue illumination.

Replacement Considerations

Official substitutes are identified as parametric equivalents within the C5SMF## series. Users should consult manufacturer documentation for current active SKUs that maintain the same physical dimensions and electrical parameters to ensure compatibility.
