155301GS73100

Overview

The Würth Elektronik 155301GS73100 is a single-color green surface-mount LED from the WL-SMSW series. It emits light at a peak wavelength of 525 nm with a typical forward voltage of 3.1 V and a test current of 20 mA. The component features a water-clear oval lens measuring 2.25 mm by 1.1 mm, providing a viewing angle of 120 degrees. It operates within a temperature range of -40 °C to +85 °C and has a maximum power rating of 72 mW.

Feature Summary

• Utilizes a water-clear oval lens for consistent optical transmission
• Designed for standard surface-mount technology (SMD/SMT) assembly processes
• Provides a wide 120-degree viewing angle for broad visibility

Applications

• General-purpose electronic equipment status indication
• Panel-mounted indicator lights for control interfaces
• Consumer appliance operational signaling

Procurement Notes

Verify the specific datasheet version before integration, as manufacturers may issue engineering change notices that alter mechanical or electrical specifications. Confirm moisture sensitivity level handling requirements during storage and reflow soldering to prevent package damage. Ensure the ordering suffix matches the required packaging format for your production line automation.

Selection Notes

Select this component when a compact green indicator with a low profile is required. The WL-SMSW series offers a distinct oval footprint suitable for space-constrained designs. Compare luminous intensity requirements against the 120-degree viewing angle to ensure adequate visibility for the intended application environment.

Part Context

This part belongs to the Würth Elektronik WL-SMSW family of side-view LEDs. The series is characterized by its small form factor and standardized pin configurations, facilitating easy replacement in existing layouts. It serves as a specialized variant within the broader discrete LED portfolio, focusing on specific color and mechanical dimensions.

Replacement Considerations

Direct substitutes must match the 3014 metric footprint, 525 nm green emission, and 3.1 V forward voltage. Verify compatibility with the 120-degree viewing angle and SMD mounting style. Cross-reference mechanical drawings to ensure height and lens shape constraints are met.
