Procurement Notes

Verify the specific suffix BF against the manufacturer's official datasheet to confirm packaging configuration and compliance status. Ensure that the ordering part number matches the exact electrical and mechanical specifications required for the target application. Cross-reference the Mouser or distributor catalog numbers to validate availability and authenticity before finalizing procurement orders.

Selection Notes

Select this component when a high-intensity white SMD LED with a wide viewing angle is required. The 3.35V forward voltage drop necessitates appropriate driver circuitry considerations compared to lower voltage alternatives. The PLCC form factor allows for space-constrained designs while maintaining robust thermal performance through standard surface-mount assembly techniques.

Part Context

This part belongs to Everlight's 57-21 series of side-view LEDs. The series is characterized by its low profile and high brightness capabilities, utilizing advanced chip-on-board or discrete die technologies. These components are widely used in consumer electronics and industrial equipment where reliable visual signaling is critical.

Replacement Considerations

Direct substitutes may include other PLCC-style white LEDs from manufacturers such as Kingbright or Osram Opto Semiconductors. Verify pin compatibility, luminous intensity ranges, and forward voltage tolerances to ensure functional equivalence without redesigning the PCB footprint.

FAQ
