155124RS73200A

Overview

The Würth Elektronik 155124RS73200A is a single-color red surface-mount LED from the WL-SMSW series. It features a 1206 (3216 metric) package with dimensions of 3.2 mm length, 1.5 mm width, and a maximum height of 1.0 mm. The component emits red light at a peak wavelength of 632 nm and a main wavelength of 624 nm. Typical forward voltage is 2 V at a test current of 20 mA, with a power rating of 48 mW. Optical intensity is rated at 70 mcd with a viewing angle of 120 degrees. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Water-clear lens with round dome style for standard optical transmission
• Side-view configuration suitable for right-angle surface mounting
• Compliant with RoHS3 specifications for environmental safety

Applications

• Electronic equipment status indicators
• Instrument panel illumination
• Consumer device signaling

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct binning and packaging format. Confirm moisture sensitivity level (MSL 3) handling requirements during storage and reflow soldering processes. Cross-reference datasheet revisions to validate electrical parameters prior to final design approval.

Selection Notes

Select this component for applications requiring side-view visibility in compact designs. Ensure PCB land pattern matches the 1206 SMD footprint dimensions. Consider the 120-degree viewing angle for visibility requirements. Verify thermal management capabilities given the 48 mW power rating and operating temperature limits.

Part Context

This part belongs to the WL-SMSW series of single-color chip LEDs manufactured by Würth Elektronik. The series offers various colors and package sizes optimized for surface mount technology. The 155124RS73200A specifically utilizes the 1206 form factor, providing a balance between optical output and board space efficiency compared to smaller packages like 0603 or larger ones like 1205.

Replacement Considerations

Consult official substitution lists for equivalent components within the same series or alternative manufacturers offering identical 1206 side-view red LED specifications.
