155124M173200A

Overview

The Würth Elektronik 155124M173200A is a surface-mount RGB LED indicator in the WL-SFSW series. It features a common anode configuration with a clear, water-clear lens. The component emits red light at 622nm (peak 632nm), green at 523nm (peak 515nm), and blue at 470nm (peak 465nm). Typical forward voltages are 2V for red, 3V for green, and 3.1V for blue. Light intensities are rated at 200mcd (red), 500mcd (green), and 150mcd (blue) at a test current of 20mA. The package is a 4-lead SMD without leads (1204 footprint), measuring 3.20mm x 1.48mm x 1.10mm max height.

Feature Summary

• Integrates three distinct primary colors (Red, Green, Blue) within a single compact surface-mount package to enable full-color mixing capabilities.
• Utilizes a rectangular lens with a domed top surface and water-clear transparency to optimize light transmission and viewing angles.
• Designed for right-angle surface mounting on printed circuit boards using a four-terminal leadless SMD form factor.

Applications

• Status indication in electronic equipment requiring multi-color signaling
• Backlighting or illumination in consumer electronics devices
• Indicator lights for control panels and user interfaces

Procurement Notes

Verify the specific suffix 'A' against the manufacturer datasheet to confirm the exact optical and electrical characteristics, as suffixes often denote binning or packaging variations. Ensure the ordering suffix matches the required reel quantity and tape type (TR, CT, or Digi-Reel). Confirm RoHS compliance status and moisture sensitivity level (MSL 3) requirements for your assembly process before procurement.

Selection Notes

Select this component when a single RGB source is preferred over discrete LEDs to save board space. The common anode configuration simplifies driving circuitry by sharing the positive terminal. Verify that the required luminous intensity for each color channel meets the application's visibility needs, noting the significant difference between green (500mcd) and blue (150mcd) outputs.

Part Context

This part belongs to the Würth Elektronik WL-SFSW series of chip LEDs. It is designed for general-purpose indication tasks where color versatility is required in a small footprint. The 1204 package size allows for high-density placement on PCBs compared to larger through-hole or standard SMD LED packages.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 1204 package dimensions, common anode configuration, and specific wavelength/voltage profiles from alternative manufacturers.
