91-21SUBC/S400-A6/TR10

Overview

The 91-21SUBC/S400-A6/TR10 is a single-color blue LED manufactured by Everlight Electronics Co Ltd. It utilizes an SMD/SMT installation style within a T-3/4 package configuration. The component emits light at a peak wavelength of 470 nm with a viewing angle of 25 degrees. Electrical characteristics include a forward current of 20 mA and a forward voltage of 3.5 V, resulting in a power rating of 110 mW. The lens features a colorless dome shape with water-clear transparency. Operating temperatures range from -40 C to +85 C, and the device is supplied in reels with a factory pack quantity of 1000.

Feature Summary

• Emits distinct blue illumination via a dedicated single-color LED chip
• Features a compact T-3/4 surface-mount package for automated assembly
• Incorporates a water-clear dome lens to direct light output effectively

Applications

• Electronic equipment status indicators
• Control panel signal lights
• Instrumentation display backlighting

Procurement Notes

Verify the specific suffix A6 against official Everlight documentation to confirm exact binning parameters and spectral consistency. Ensure compatibility with standard reflow soldering profiles for SMD components. Confirm moisture sensitivity levels and storage conditions prior to assembly to maintain device reliability during manufacturing processes.

Selection Notes

Select this component when a standard blue indicator is required for surface-mount designs. The T-3/4 form factor offers a balance between visibility and board space efficiency compared to larger through-hole alternatives. Consider the 25-degree viewing angle for applications requiring focused directional light rather than wide dispersion.

Part Context

This part belongs to Everlight's extensive portfolio of single-color LEDs designed for general indication purposes. The product line emphasizes reliable performance across various industrial and consumer electronics applications. The manufacturer provides comprehensive datasheets detailing electrical limits and optical characteristics for integration into circuit designs.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Generic replacements may differ in luminous intensity or forward voltage requirements. Validate pinout compatibility and thermal characteristics before substituting to ensure circuit integrity.
