IN-S42ETSR

LED Indication - Discrete Overview

The IN-S42ETSR is a single-color red surface-mount LED manufactured by Inolux, housed in a compact 0402 (1005 Metric) package with dimensions of 1.0 mm x 0.5 mm x 0.25 mm. It features a clear lens and emits light at a viewing angle of 110° to 130°. The component operates with a typical forward voltage of 2 V and a test current of 20 mA. It is designed for top-mount installation and supports moisture-sensitive handling protocols.

LED Indication - Discrete Feature Summary

• Compact 0402 surface-mount form factor suitable for space-constrained designs
• Clear lens configuration for standard visibility applications
• Wide viewing angle range for broad illumination distribution

LED Indication - Discrete Applications

• General electronic device status indication
• Panel indicator lights
• Consumer electronics signaling

LED Indication - Discrete Procurement Notes

Verify the specific datasheet version for accurate electrical characteristics and reliability data before integration. Confirm moisture sensitivity level (MSL) handling requirements during storage and reflow soldering processes. Ensure compatibility with automated pick-and-place equipment due to the small 0402 package size. Cross-reference pinout configurations if utilizing non-standard footprints.

LED Indication - Discrete Selection Notes

Select this component when a low-profile red indicator is required for high-density PCB layouts. The 0402 package offers a balance between visibility and board space efficiency compared to larger packages. Consider the 2 V forward voltage drop for power budget calculations in low-voltage circuits. Evaluate the wide viewing angle against optical requirements for user-facing interfaces.

LED Indication - Discrete Part Context

This part belongs to Inolux's single-color LED portfolio, specifically within the IN-S42 series designed for surface-mount technology. The series emphasizes miniaturization while maintaining reliable optical performance for industrial and consumer applications. It complements other variants in the lineup that offer different colors or package sizes.

LED Indication - Discrete Replacement Considerations

Direct substitutes may include other 0402 red LEDs from manufacturers such as Kingbright or Everlight, provided they match the 1.0x0.5x0.25 mm footprint and similar forward voltage specifications. Verify luminous intensity and viewing angle compatibility to ensure equivalent visual performance in the target application.
