LED Indication - Discrete Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact binning and packaging specifications. Ensure that the procurement channel provides valid traceability documentation for RoHS compliance status. Cross-reference the part number with the latest Everlight device selection guide to confirm availability and any potential obsolescence notices before finalizing purchase orders.

LED Indication - Discrete Selection Notes

Select this component when designing passenger information systems requiring precise optical alignment with other primary colors. The matched radiation pattern facilitates effective color mixing in graphic displays. Consider the radial mount form factor for through-hole PCB integration where a low profile of 6.1 mm is required. Validate thermal management strategies given the 85 °C maximum operating temperature limit.

LED Indication - Discrete Part Context

This part is categorized under Everlight's precision optical performance oval LEDs, specifically engineered for passenger information signs. It sits within the broader Single Color LEDs subcategory of the company's optoelectronics portfolio. The design emphasizes superior performance in outdoor environments, distinguishing it from standard indicator LEDs through its specialized optical output and robust material composition.

LED Indication - Discrete Replacement Considerations

Consult the Everlight Device Selection Guide for direct substitutes such as the 3474/R3DB-AGKB/P/MS variant. Verify compatibility regarding pin configuration and mechanical dimensions before substitution. Ensure that any replacement maintains the required 635 nm peak wavelength and 900 mcd intensity for consistent visual performance in signage applications.
