Procurement Notes

Verify the specific suffix D09 against manufacturer documentation to confirm exact binning or packaging variations. Ensure compatibility with moisture sensitivity levels during storage and handling. Cross-reference the 1311 package footprint with PCB layout requirements before integration.

Selection Notes

Select this component when a compact blue SMD LED with moderate intensity is required. Consider the 3.3 V forward voltage drop for circuit design. Evaluate the 120-degree viewing angle against optical coverage needs. Confirm thermal management capabilities for the specified operating temperature range.

Part Context

This part belongs to Kingbright's single-color LED portfolio, specifically within the blue LED category. It shares the standard 3528 form factor family but differs in color and electrical characteristics from other variants like red or green models. The D09 suffix denotes specific manufacturing attributes defined by the supplier.

Replacement Considerations
