Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, such as tape and reel or cut tape, matches production requirements. Confirm that the component status aligns with long-term supply needs, as availability may vary. Cross-reference the datasheet parameters against system electrical constraints to validate compatibility before finalizing procurement orders.

Selection Notes

Select this component when a yellow indication with high visibility is required in space-constrained designs. The 2-PLCC form factor supports automated assembly processes. Ensure the forward voltage and current ratings are compatible with the driving circuitry. Consider the 120-degree viewing angle for optimal visual accessibility in the final application layout.

Part Context

This part belongs to the TOPLED® family, known for standardized footprints and consistent performance across various colors. The LY series represents a specific line of single-color LEDs designed for general-purpose indication. The manufacturer ams OSRAM provides extensive documentation for this series to support engineering integration and reliability assessment.

Replacement Considerations

Direct substitutes include other yellow LEDs in the 2-PLCC package with similar electrical characteristics. Verify mechanical dimensions and pinout compatibility before substitution. Alternative parts must match the forward voltage and luminous intensity requirements of the original design.
