Procurement Notes

This component is officially classified as obsolete and no longer manufactured by Dialight. Procurement must rely on remaining distributor stock or secondary market sources. Verify lot dates and storage conditions carefully due to potential shelf-life degradation. Moisture sensitivity level 3 requires adherence to reflow profiles if stored beyond factory limits. Cross-reference approved substitutes are available from other manufacturers for active production needs.

Selection Notes

Designers should prioritize alternative components due to the discontinuation status of this part. Evaluate replacement options based on matching electrical parameters such as forward voltage and peak wavelength. Ensure mechanical compatibility with existing footprints when selecting substitute LEDs. Confirm that optical intensity meets application requirements during the transition phase.
