LED Indication - Discrete Procurement Notes

Verify component availability as the part status is listed as obsolete. Confirm lead times with authorized distributors due to potential supply constraints. Ensure ordering suffixes match specific binning requirements if precise color matching is critical for the application. Cross-reference datasheets for updated thermal derating curves before finalizing designs.

LED Indication - Discrete Selection Notes

Select this component when space-constrained designs require two distinct signal colors in a single footprint. Consider the 120-degree viewing angle for applications requiring wide visibility. Evaluate the 20mA current rating against power dissipation limits in high-density PCB layouts. Ensure the PLCC-4 package dimensions align with existing board footprints and reflow soldering profiles.

LED Indication - Discrete Part Context
