EFY3863X

LED Indication - Discrete Overview

The EFY3863X is a single-color yellow LED from Stanley Electric Co, designed for discrete indication. It features a clear lens with a round, domed top in a 3mm (T-1) radial package suitable for through-hole mounting. The component emits light at a peak wavelength of 592nm and a dominant wavelength of 590nm. Typical forward voltage is 1.9V at a test current of 20mA, providing a millicandela rating of 120mcd. The viewing angle is 70 degrees, and the maximum height is 5.90mm.

LED Indication - Discrete Feature Summary

• Clear lens construction for precise visibility
• Radial through-hole mounting configuration
• Yellow emission with 70-degree viewing angle

LED Indication - Discrete Applications

• General equipment status indication
• Panel indicator lights
• Consumer electronics status signals

LED Indication - Discrete Procurement Notes

Verify part status as obsolete before procurement planning. Confirm availability of substitutes such as OVLBY4C7 from TT Electronics if replacement is required. Ensure compatibility with existing through-hole assembly processes and verify that the 3mm radial package dimensions match the target PCB footprint without modification.

LED Indication - Discrete Selection Notes

Select this component for applications requiring a standard 3mm through-hole yellow LED with a wide viewing angle. The 1.9V forward voltage is suitable for low-voltage logic circuits. Consider the 70-degree beam spread for general visibility needs rather than focused directional lighting requirements.

LED Indication - Discrete Part Context

This component belongs to the Stanley Electric discrete LED product line, specifically within the 3mm (T-1) form factor category. It is engineered for reliable visual signaling in electronic assemblies where standard through-hole technology is preferred over surface-mount alternatives.
