IN-S42DS5SR

LED Indication - Discrete Overview

The IN-S42DS5SR is a single-color red LED from Inolux, designed for surface-mount technology in the 0402 (1005 metric) package. It emits light at a wavelength of 631 nm with a viewing angle of 145 degrees. The component operates within a forward voltage range of 2 to 2.4 VDC and provides an intensity of 18 mcd when driven at 5 mA. Physical dimensions are specified as 1.0 mm x 0.55 mm x 0.3 mm. It is classified as moisture sensitive and is typically supplied in reel packaging.

LED Indication - Discrete Feature Summary

• Side-view optical configuration for visibility
• Compact 0402 surface-mount footprint
• Wide 145-degree viewing angle

LED Indication - Discrete Applications

• Device status indication
• Panel indicator lights
• Consumer electronics signaling

LED Indication - Discrete Procurement Notes

Verify the specific ordering suffix to confirm exact binning parameters such as chromaticity coordinates and intensity levels, as these can vary between manufacturing lots. Confirm moisture sensitivity level handling requirements during storage and reflow soldering processes to ensure device reliability. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

LED Indication - Discrete Selection Notes

Select this component when a low-profile, side-emitting red indicator is required for space-constrained designs. The 0402 package offers a small footprint suitable for dense PCB layouts. Ensure the driving circuit supports the specified forward voltage range and current limits to maintain consistent brightness and prevent thermal stress on the LED junction.

LED Indication - Discrete Part Context

This part belongs to Inolux's discrete LED portfolio, focusing on standard single-color indicators. The 0402 series is widely used in portable devices where size is critical. The IN-S42DS5SR specifically addresses applications requiring high visibility through its wide viewing angle and side-view orientation, distinguishing it from top-emitting variants in the same package family.

LED Indication - Discrete Replacement Considerations

Direct substitutes must match the 0402 SMD package, red color, and side-view orientation. Verify that alternative parts meet the 145-degree viewing angle and similar forward voltage characteristics to ensure electrical compatibility without redesigning the driver circuitry.
