3294-15USOC/S400-A6 is listed in the LED Indication - Discrete range at ChipApex. The manufacturer field lists Everlight Electronics Co Ltd. Its product description is LED RED CLEAR 3MM ROUND T/H. Review the specifications below when checking this part for your BOM.
The Everlight 3294-15USOC/S400-A6 is a through-hole, single-color LED lamp featuring an AlGaInP chip that emits reddish-orange light. It utilizes a water-clear lens with a 3 mm round dome shape and operates at a peak wavelength of 615 nm. The component has a forward voltage of 2.0 V and a power rating of 125 mW. It is designed for standard PCB mounting in bulk packaging.
This component is officially classified as obsolete by the manufacturer and is no longer in production. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm RoHS compliance status and lot dates carefully, as availability is limited to existing inventory rather than new manufacturing runs.
Engineers replacing this part should prioritize parametric equivalents with matching 3 mm through-hole dimensions and similar forward voltage characteristics. Since the original part is discontinued, selecting a modern substitute requires verifying spectral output compatibility and ensuring the replacement meets the same mechanical footprint requirements for existing PCB layouts.
This LED belongs to Everlight's 5.0mm/3mm round type lamp series, specifically utilizing AlGaInP technology for red-to-orange spectrum emission. The S400-A6 suffix typically denotes specific binning or lens configuration within the product family. As an older generation component, it represents standard through-hole LED technology prior to widespread surface-mount dominance in indicator applications.
Public confirmed substitutes include the 3294-15SUBC/S400-A6. Verify electrical parameters match before substitution.
