333-2UTC/S400-A6

LED Indication - Discrete Overview

The 333-2UTC/S400-A6 is a single-color infrared LED emitter manufactured by Everlight Electronics Co Ltd. It utilizes a through-hole radial mounting style within a T-1 (3 mm) package configuration. The component emits at a peak wavelength of 940 nm with a viewing angle of 20 degrees. Key electrical parameters include a typical forward voltage of 1.4 V and a maximum DC forward current of 100 mA. The device operates reliably within a temperature range of -25°C to +85°C.

LED Indication - Discrete Procurement Notes

Verify the specific suffix 'S400-A6' against official Everlight documentation to confirm binning, wavelength tolerance, and lens transparency specifications. Ensure that the procurement channel provides valid RoHS compliance certificates and material safety data sheets. Confirm that the supplier sources directly from authorized distribution networks to guarantee component authenticity and traceability throughout the supply chain.

LED Indication - Discrete Selection Notes

Select this component when a 3 mm radial through-hole form factor is required for infrared emission. It is suitable for designs needing a 20-degree beam spread and operation up to 100 mA forward current. Consider thermal management requirements given the 85°C maximum operating limit. Evaluate alternative packages if surface-mount constraints or wider viewing angles are necessary for the specific application geometry.

LED Indication - Discrete Part Context

This part belongs to Everlight's standard discrete infrared LED portfolio, specifically the T-1 series designed for general-purpose signaling. It complements other variants in the 333 series that offer different wavelengths or package styles. The component serves as a fundamental optoelectronic element for creating optical links in embedded systems and standalone electronic devices requiring reliable infrared transmission.

LED Indication - Discrete Replacement Considerations

Direct substitutes may include other 940 nm T-1 radial IR LEDs from Everlight such as the IR333C-A, provided pin compatibility and electrical ratings align. Verify that any replacement maintains the same 20-degree viewing angle and forward voltage characteristics to ensure circuit performance consistency without redesign.
