156125RB73000

Overview

The Würth Elektronik 156125RB73000 is a WL-SBRW series surface-mount bi-color LED featuring red and blue chips in a 4-SMD bottom-entry package. It operates with a forward current of 20 mA per color, delivering 110 mcd for red and 170 mcd for blue. The device has a typical forward voltage of 2 V for red and 3.2 V for blue, with peak wavelengths at 632 nm and 470 nm respectively. Dimensions are 3.2 mm x 1.2 mm x 0.8 mm, supporting a viewing angle of 120 degrees.

Feature Summary

• Bi-color configuration integrating red and blue LEDs within a single compact SMD footprint
• Bottom-entry mounting design facilitates standard surface-mount assembly processes
• Water-clear lens material provides high light transmission efficiency

Applications

• Status indication on electronic circuit boards
• Multi-state signaling in industrial control panels
• Visual feedback systems in consumer electronics devices

Procurement Notes

Verify the specific ordering suffix to confirm the exact binning parameters for wavelength and intensity. Ensure the procurement documentation matches the WL-SBRW series specifications. Confirm RoHS compliance status through official manufacturer certificates prior to integration into production lines.

Selection Notes

Select this component when space-constrained designs require dual-color functionality without increasing board area. Consider the 120-degree viewing angle for visibility requirements. Evaluate the low power consumption characteristics against thermal management constraints in dense PCB layouts.

Part Context

This part belongs to the WL-SBRW family of bi-color LEDs from Würth Elektronik. The series specializes in small-form-factor indicators that combine multiple chip colors into one package. It serves as a solution for applications needing distinct visual outputs from minimal physical real estate.

Replacement Considerations

Direct substitutes include other WL-SBRW variants with different color combinations or intensities. Verify pinout compatibility and mechanical dimensions before swapping. Consult official cross-reference lists for equivalent performance metrics.
