C4SMB-AGY-CU4W3251

Overview

The C4SMB-AGY-CU4W3251 is a single-color amber LED from the Screen Master series, manufactured by Cree LED. It utilizes a through-hole mounting style with an oval lens measuring 4.2 mm by 6.3 mm. The component emits at a dominant wavelength of 590 nm and provides a luminous intensity range of 180 to 450 mcd. Electrical characteristics include a forward voltage of 2.1 V at a forward current of 20 mA, with a power rating of 70 mW. The lens features water-clear transparency, and the device operates within a temperature range of -40°C to +85°C.

Feature Summary

• Oval lens design optimized for visibility in signage applications
• High reliability performance suitable for demanding environments
• Water-clear lens transparency for efficient light transmission

Applications

• Transportation signage
• Message boards
• Information signs
• Digital displays

Procurement Notes

Verify component authenticity against official Cree LED documentation. Confirm that the specific ordering suffix matches the required electrical parameters and lens specifications. Ensure compliance with RoHS directives as indicated in the datasheet. Check for availability status as distribution channels may vary. Validate package dimensions for mechanical fitment prior to integration.

Selection Notes

Select this component when high-brightness amber illumination is required for outdoor or indoor signage. The oval shape offers distinct visual characteristics compared to round LEDs. Consider the forward voltage drop for driver circuit design. Evaluate the viewing angle requirements against the application's visibility needs. Ensure thermal management strategies align with the maximum operating temperature limits.

Part Context

This part belongs to the Screen Master family of high-brightness LEDs designed specifically for signage and display applications. The series emphasizes durability and optical performance in challenging lighting conditions. Cree LED integrates multiple dies in some variants, but this specific model is a single-color through-hole device. The family supports various colors including red, green, blue, and amber for full-color or monochrome displays.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching electrical parameters, package dimensions, and optical characteristics. Verify compatibility with existing PCB layouts and driver circuits before considering alternative components.
