• Frequency modulation (FM) circuit implementations

Procurement Notes

This product has been officially discontinued by the manufacturer. Verification of availability should focus on historical stock or authorized distributors offering remaining inventory. Designers must confirm end-of-life status before finalizing procurement plans, as supply is no longer guaranteed through standard manufacturing channels.

Selection Notes

Engineers selecting this component should account for its discontinued status when planning long-term production. The SOD-523 package limits current handling capabilities compared to larger footprints. Verify that the 6 V reverse voltage rating aligns with the specific circuit's peak operating conditions to prevent breakdown.

Part Context

The BB202 belongs to the broader family of RF small-signal varactor diodes offered by NXP. These components are typically utilized in high-frequency analog applications where precise capacitance control via voltage is required. The BB202 specifically targets compact designs due to its small surface-mount footprint.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, alternative sourcing requires identifying functionally equivalent varactors with matching capacitance ratios and voltage ratings from other manufacturers.
