IN-S42ATB

LED Indication - Discrete Overview

The IN-S42ATB is a blue surface-mount LED from Inolux, designed for discrete indication applications. It features a clear lens and operates at a peak wavelength of 468nm with a main wavelength of 470nm. The component utilizes a standard configuration within a 0402 (1005 Metric) package, measuring 1.00mm in length, 0.50mm in width, and a maximum height of 0.55mm. It exhibits a viewing angle of 120 degrees and delivers an optical intensity of 100mcd when tested at 20mA. The typical forward voltage is 3.1V. The device is moisture-sensitive (MSL Level 4) and complies with RoHS3 standards.

LED Indication - Discrete Feature Summary

• Compact 0402 surface-mount form factor suitable for space-constrained PCB layouts
• Clear colorless lens providing high transparency for the blue emission
• Wide 120-degree viewing angle for broad visibility
• Standard single-color configuration for general indication purposes

LED Indication - Discrete Applications

• Status indication on electronic control boards
• Power state signaling in consumer devices
• Component presence detection indicators
• Operational feedback in compact instrumentation

LED Indication - Discrete Procurement Notes

Verify the specific ordering suffix to ensure the correct packaging type matches production requirements, such as tape and reel or cut tape. Confirm that the receiving facility's reflow profile aligns with the MSL Level 4 sensitivity rating to prevent moisture-induced damage during soldering. Cross-reference the datasheet for any recent PCN updates regarding material changes or packaging modifications before finalizing purchase orders.

LED Indication - Discrete Selection Notes

Select this component when a small footprint is required alongside a wide viewing angle for blue status lighting. The 0402 package allows for high-density mounting compared to larger LEDs. Ensure the circuit design accounts for the 3.1V forward voltage drop at the specified 20mA test current. Consider the 100mcd intensity level against ambient lighting conditions to guarantee adequate visibility for the intended application.

LED Indication - Discrete Part Context

This part belongs to the IN-S42AT series of SMD LEDs from Inolux, which focuses on compact indicator solutions. The series offers various colors within the same mechanical envelope, facilitating standardized board designs across different product variants. The IN-S42ATB specifically addresses the need for blue illumination in modern electronics where size constraints are critical.

LED Indication - Discrete Replacement Considerations

QBLP595-IB-2 by QT Brightek is documented as a similar alternative. Verify electrical parameters and mechanical dimensions carefully, as direct pin-to-pin substitution may require circuit adjustment due to potential differences in forward voltage or luminous intensity.
