150040RS73220

Overview

The Würth Elektronik 150040RS73220 is a single-color red LED from the WL-SMCC series, designed for surface-mount technology in a compact 0402 (1005 metric) package. It features a water-clear lens with a rectangular shape and平顶 style, emitting light at a peak wavelength of 632 nm and a dominant wavelength of 624 nm. The component provides an optical intensity of 110 mcd when driven at a forward current of 20 mA, with a typical forward voltage of 2 V. It has a maximum height of 0.35 mm and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Compact 0402 surface-mount footprint suitable for space-constrained designs
• Water-clear lens material ensures high light transmission efficiency
• Wide viewing angle of 120 degrees for broad visibility
• RoHS compliant construction supporting environmental regulations

Applications

• General status indication on electronic circuit boards
• Power supply unit visual feedback systems
• Consumer electronics device signaling
• Industrial control panel indicators

Procurement Notes

Verify the specific datasheet version prior to ordering, as packaging labels and quantity specifications may undergo periodic updates through Production Change Notices. Confirm that the required moisture sensitivity level classification aligns with your facility's floor life management protocols. Ensure that the selected reel or cut-tape format matches your automated assembly equipment capabilities. Cross-reference the latest RoHS certification status to guarantee compliance with current regional environmental directives.

Selection Notes

Select this component when a low-profile red indicator is required for dense PCB layouts. The 0402 package offers a smaller alternative to larger SMD LEDs while maintaining adequate brightness for standard visibility needs. Consider the 20 mA test current rating for driving circuit design to ensure optimal luminous output without exceeding thermal limits. The clear lens option is preferred over diffused variants when precise directional lighting is necessary for the application.

Part Context

This part belongs to the WL-SMCC series of chip LEDs manufactured by Würth Elektronik. The series focuses on providing reliable monochromatic light sources in miniature form factors. The WL-SMCC line is engineered for high-volume surface-mount production processes, offering consistent photometric performance across batches. It represents a standard solution for basic visual signaling tasks where size and cost efficiency are primary design constraints.

Replacement Considerations

Direct substitutes within the same series include 150040RS73240, which shares identical physical dimensions but differs in wavelength characteristics. Designers must verify electrical compatibility and optical intensity requirements before swapping parts. Alternative packages such as 0603 offer larger footprints but may provide different thermal handling capabilities.
