LED Indication - Discrete Procurement Notes

This specific part number is officially listed as obsolete or discontinued by the manufacturer. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or secondary market suppliers. Buyers must confirm the date code and physical condition carefully, as availability is limited and supply chain continuity cannot be guaranteed through standard manufacturing channels.

LED Indication - Discrete Selection Notes

Engineers requiring this component should evaluate alternative parts within the same 45-21 series family that are currently in active production. Selection criteria should prioritize matching the mechanical footprint, electrical characteristics, and optical output specifications of the original design to ensure compatibility without requiring PCB layout modifications.

LED Indication - Discrete Part Context

This component belongs to the Everlight 45-21 series of low-power surface-mount LEDs. The series is characterized by its small form factor and suitability for space-constrained designs. The specific suffix indicates the color temperature and packaging variant, distinguishing it from other colors or lens types within the broader product line.

LED Indication - Discrete Replacement Considerations

Direct replacement options include other variants within the Everlight 45-21 series that share the identical 2-PLCC package dimensions. Verify that substitute parts match the required forward voltage and luminous intensity specifications to maintain consistent performance in the target application.
