Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Verification of current availability through authorized distributors is required, as standard supply channels may no longer stock new units. Engineers should confirm end-of-life status and plan for alternative sourcing strategies if long-term production support is needed.

Selection Notes

Designers requiring this specific part number must account for its discontinued status when planning future productions. The electrical parameters, including the 30 V rating and 2.2 pF baseline capacitance, define its suitability for specific RF tuning ranges. Alternative components from the same family or comparable varactors should be evaluated for pin compatibility and performance equivalence.

Part Context

The BB565H7903XTMA1 belongs to the BB565 series of varactor diodes from Infineon Technologies. This series is characterized by silicon varactor technology intended for high-frequency applications. The specific suffix indicates the tape-and-reel packaging format and internal manufacturing code associated with this particular variant.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers should consult official replacement guides or contact the manufacturer directly for qualified alternatives that match the SCD-80 footprint and electrical specifications.
