• Oval lens design with water-clear transparency
• Through-hole radial package configuration

Applications

• Fiber optic communication systems
• Display technologies
• Medical imaging equipment
• Industrial automation indicators

Procurement Notes

Verify component status as obsolete or end-of-life documentation may apply. Confirm availability through authorized distributors only. Check for product change notifications regarding material or performance updates. Ensure compatibility with existing board layouts due to specific dimensional requirements.

Selection Notes

Select this component for applications requiring a compact blue indicator with specific oval form factors. Consider the 475nm wavelength for visibility requirements. Evaluate the 20mA current limit against drive circuit capabilities. Verify mechanical fit within the designated through-hole footprint constraints.

Part Context

This part belongs to the Cree LED Screen Master series, designed for high-visibility indication. It represents a legacy blue LED option within the manufacturer's discrete component portfolio. The oval shape distinguishes it from standard round or rectangular alternatives in the same family.

Replacement Considerations

Consult official datasheets for direct pin-compatible substitutes. Verify electrical parameters such as forward voltage and luminous intensity match before substitution. Check for updated RoHS compliance status if required.
