17-21/S2C-BL2M2LY/3T

LED Indication - Discrete Overview

The 17-21/S2C-BL2M2LY/3T is a single-color surface-mount LED manufactured by Everlight Electronics. It utilizes an AlGaInP material system to emit brilliant yellow-green light with a dominant wavelength range of 567.5–575.5 nm. The component features a white diffused lens and operates in a compact 0603 package with a height of 0.8 mm. Designed for automated placement, it supports infrared and vapor phase reflow soldering processes.

LED Indication - Discrete Feature Summary

• Compact 0603 surface-mount package with 0.8 mm height for high board density
• Compatible with automatic placement equipment and standard reflow soldering
• Mono-color emission with white diffused lens for uniform light distribution
• Lead-free construction compliant with environmental standards

LED Indication - Discrete Applications

• Automotive dashboard and switch backlighting
• Telecommunication device indicators and LCD backlighting
• General purpose indicator lighting

LED Indication - Discrete Procurement Notes

Verify the specific ordering suffix against the official Everlight datasheet to confirm optical and electrical characteristics. Ensure compatibility with the intended reflow soldering profile. Confirm that the requested variant matches the required dominant wavelength and luminous intensity specifications for the application.

LED Indication - Discrete Selection Notes

Select this component for applications requiring a low-profile SMD LED with yellow-green emission. The 0603 form factor is suitable for space-constrained designs. Verify that the operating current aligns with the specified forward voltage requirements. Consider the white diffused lens option if uniform illumination is necessary rather than a focused beam.

LED Indication - Discrete Part Context

This part belongs to the 17-21 series of 0603 package chip LEDs from Everlight. The series is designed for miniature applications where lightweight components and smaller board sizes are prioritized. The specific model denotes a yellow-green emission variant within the broader mono-color LED portfolio.

LED Indication - Discrete Replacement Considerations

Consult the official Everlight Device Selection Guide for direct substitutes. Cross-reference compatible part numbers such as those in the 19-21 series for similar package dimensions but verify all electrical parameters before substitution.
