Procurement Notes

This component is officially listed as obsolete or end-of-life by the manufacturer. Availability is restricted, and sourcing may require checking secondary distributors for remaining stock. Verification of authenticity and condition is critical due to the discontinued status. Engineers should confirm lead times and supply constraints before finalizing designs that rely on this specific part number.

Selection Notes

Designers should evaluate the 30 V reverse voltage limit and 2.2 pF capacitance specification against circuit requirements. The SC-80 package dimensions must be verified for PCB layout compatibility. Given the obsolete status, alternative components with similar capacitance ratios and voltage ratings should be considered for new production runs to ensure long-term supply stability.

Part Context

The BB565H7902XTSA1 belongs to the BB565 series of varactor diodes from Infineon Technologies. These devices are specifically engineered for frequency tuning applications in consumer electronics. The H7902 suffix denotes specific binning or manufacturing lot characteristics within the series, distinguishing it from other variants like the BB565E7908.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers must identify cross-references based on matching electrical parameters such as 30 V rating, SC-80 package, and capacitance ratio.
