EFR3864X

LED Indication - Discrete Overview

The EFR3864X is a red, clear LED from Stanley Electric Co., designed for through-hole mounting in a 3mm (T-1) radial package. It features a domed top lens with a 20-degree viewing angle and emits at a dominant wavelength of 626nm. Typical forward voltage is 1.9V at a test current of 20mA, delivering an intensity of 1280 mcd. The component has a maximum height of 5.90mm. This discrete indicator is currently classified as obsolete by the manufacturer.

LED Indication - Discrete Procurement Notes

Verify part status carefully as this model is officially obsolete. Confirm availability of authorized substitutes or surplus stock. Ensure compatibility with existing board layouts when sourcing replacements. Check datasheet revisions for any historical parameter variations before integration into new designs.

LED Indication - Discrete Selection Notes

Select based on required red visibility and narrow beam characteristics. Consider the 1.9V forward voltage drop for circuit design. Evaluate mechanical fit within the 3mm T-1 housing constraints. Assess obsolescence impact on long-term supply chain stability and replacement strategies.

LED Indication - Discrete Part Context

This component belongs to Stanley Electric's discrete LED lineup, historically utilized in aviation and automotive sectors. The 3mm form factor provides a compact solution for panel mounting. Its specific optical profile suits applications requiring focused visual feedback rather than broad illumination.

LED Indication - Discrete Replacement Considerations

Similar available substitutes exist but require verification of pinout and luminous intensity matching. Cross-reference electrical parameters such as forward voltage and peak wavelength to ensure functional equivalence in the target application.
