C5SMF-RJF-CU34QBB1

Overview

The C5SMF-RJF-CU34QBB1 is a single-color red 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 shape and water-clear transparency. Key electrical parameters include a forward voltage of 2.1 V at a test current of 20 mA, with a power rating of 130 mW. The device emits light at a peak wavelength of 621 nm and provides a luminous intensity of 1310 mcd. The viewing angle is specified as 100 degrees by 45 degrees. Operating temperatures range from -40 °C to +95 °C.

Feature Summary

• Features a water-clear oval lens for optimized light transmission in indicator applications.
• Designed for through-hole mounting within a standard 5 mm T-1 3/4 radial package.
• Delivers high luminous intensity suitable for visible status indication.

Applications

• Panel-mounted status indicators
• Equipment front-panel signaling
• Control board visual feedback

Procurement Notes

Verify component authenticity using manufacturer serial codes or lot markings upon receipt. Confirm datasheet revisions match the production batch date code. Ensure storage conditions comply with moisture sensitivity levels if applicable. Cross-reference ordering suffixes to verify exact optical and electrical tolerances before integration into final assembly processes.

Selection Notes

Select this component when a 5 mm through-hole form factor is required for red indication. The 621 nm wavelength offers distinct visibility compared to standard 630 nm variants. Consider the 100x45 degree viewing angle for directional lighting needs. Evaluate the 2.1 V forward voltage against available drive circuitry to ensure proper current limiting resistor selection for the target operating environment.

Part Context

This part belongs to the Screen Master family of LEDs, which are engineered for high-brightness performance in compact packages. The C5SMF series represents a specific line of 5 mm through-hole devices. The RJF suffix typically denotes red color and specific binning characteristics within the Cree LED portfolio, distinguishing it from other colors or lens types in the same mechanical footprint.

Replacement Considerations

The C5SMF-RJS-CU14QBB1 is a documented equivalent substitute. It maintains critical electrical parameters including 2.1 V forward voltage, 20 mA test current, and 621 nm wavelength. Verify mechanical compatibility and lens tint differences between the CU and JS suffix variants before substitution.
