LED Indication - Discrete Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact binning and chromaticity coordinates. Ensure that the procurement documentation references the correct revision level for the 5mm white lamp LED specification. Cross-reference the part number with the latest Seoul Semiconductor product list to confirm availability and compliance status.

LED Indication - Discrete Selection Notes

Select this component when a standard 5mm through-hole white LED is required for visual signaling applications. The 22-degree viewing angle provides a focused light output suitable for direct line-of-sight indication. Consider the 3.2V forward voltage drop when designing the current-limiting resistor network for the target circuit application.

LED Indication - Discrete Part Context

This discrete LED belongs to the Seoul Semiconductor white lamp LED series. It serves as a general-purpose indicator component within the broader portfolio of lighting and display solutions offered by the manufacturer. The part is distinct from surface-mount or high-power variants in the same family.

LED Indication - Discrete Replacement Considerations

Consult official substitution guides for compatible 5mm white LEDs with similar electrical characteristics. Verify mechanical compatibility of the radial lead spacing before replacing the original component in existing assemblies.
