C4SMN-BJF-CR34Q4S1

Overview

The C4SMN-BJF-CR34Q4S1 is a single-color blue LED from the Screen Master series by Cree LED. It features a through-hole mounting style with an oval lens shape and water-clear transparency. The component operates at a forward current of 20 mA and a forward voltage of 3.4 V, with a power rating of 140 mW. It emits light at a wavelength of 475 nm with a typical luminous intensity of 550 mcd. The lens dimensions are 4.2 mm in length, 3.1 mm in width, and 6.3 mm in height. The device supports a viewing angle of 100 degrees horizontally and 45 degrees vertically, functioning within a temperature range of -40°C to +95°C.

Feature Summary

• Screen Master series design for uniform illumination
• Oval lens geometry with water-clear transparency
• Through-hole radial mounting configuration

Applications

• Indicator lighting in electronic equipment
• Control panel status displays
• Instrumentation front panels

Procurement Notes

Verify the specific suffix CR34Q4S1 against official Cree LED documentation to confirm binning and optical characteristics. Ensure compatibility with existing PCB layouts for the 4.2 mm x 3.1 mm footprint. Confirm RoHS compliance status via the manufacturer's latest datasheet before integration.

Selection Notes

Select this component when a blue indicator with oval aesthetics is required. Compare the 550 mcd intensity against application visibility needs. Consider the 3.4 V forward voltage drop for circuit design. Verify thermal management requirements for the specified operating temperature range.

Part Context

This part belongs to the Screen Master family of 4-mm oval LEDs. It shares the physical package dimensions with other variants in the series but differs in color and optical output. The model designation indicates a blue emission variant within the broader Cree LED portfolio.

Replacement Considerations

Consult official substitution guides for direct equivalents. Cross-reference pinout and dimensional tolerances if considering alternative manufacturers. Verify electrical parameters match system requirements before swapping.
