C4SMB-RGY-CV24QBB1

Overview

The Cree LED C4SMB-RGY-CV24QBB1 is a single-color red light-emitting diode belonging to the Screen Master series. It features a 4-mm oval lens with water-clear transparency, designed for through-hole mounting. The component emits at a wavelength of 621 nm and provides a typical luminous intensity range of 1050 to 1300 mcd. Electrical characteristics include a forward voltage of approximately 2.1 V at a forward current of 20 mA, with a power rating of 70 mW. The device operates within a temperature range of -40°C to +85°C and utilizes an ammo pack packaging format.

Feature Summary

• High-brightness red emission optimized for visibility in bright ambient conditions
• Water-clear oval lens design ensures consistent optical performance
• Through-hole construction facilitates standard PCB assembly processes

Applications

• Status indication in industrial control panels
• Visual signaling in consumer electronic devices
• Instrument panel illumination for automotive or medical equipment

Procurement Notes

Verify the specific binning codes for luminous intensity and chromaticity coordinates against project requirements before ordering. Confirm that the through-hole lead form matches the target printed circuit board layout. Ensure compatibility with standard wave soldering or manual soldering profiles specified in the official datasheet to maintain junction integrity and long-term reliability.

Selection Notes

Select this component when high visible brightness is required for red status indicators in compact assemblies. The 4-mm oval footprint offers a balance between visual prominence and board space efficiency compared to larger indicator LEDs. Consider the forward voltage drop and thermal management capabilities relative to the driving circuit design to ensure stable operation across the specified temperature range.

Part Context

This part belongs to the Cree Screen Master family, which specializes in high-intensity discrete LEDs for demanding visual applications. The C4SMB series specifically targets markets requiring reliable, high-luminance indicators with standardized mechanical dimensions. This lineage emphasizes optical consistency and robustness for commercial and industrial environments where clear visual feedback is critical.

Replacement Considerations

Direct substitutes may include other 4-mm oval red LEDs from manufacturers such as Kingbright or Everlight, provided they match the electrical parameters and mechanical outline. Verify pin spacing and lens shape compatibility to ensure proper fitment without modifying existing tooling or PCB designs.
