RF Transceiver ICS Procurement Notes

This component is officially designated as obsolete by the manufacturer. Availability is restricted to existing stock or surplus channels rather than direct production orders. Verification of authenticity and lot history is critical due to the end-of-life status. Buyers should confirm the specific revision and packaging condition before acquisition, as supply chain continuity is not guaranteed through standard manufacturing pipelines.

RF Transceiver ICS Selection Notes

Engineers should avoid selecting this part for new product development due to its obsolete status. The manufacturer explicitly states it is not recommended for new designs. Alternative components within the AIROC family that support current design requirements and long-term availability should be evaluated instead. Transitioning to newer generations ensures ongoing technical support and supply stability.

RF Transceiver ICS Part Context

The CYW4339XKUBGT belongs to Infineon's AIROC series of wireless connectivity solutions. It represents a previous generation of integrated RF and MCU technology designed for compact form factors. As an obsolete component, it serves primarily in maintenance, repair, and legacy system contexts rather than modern innovation cycles.

RF Transceiver ICS Replacement Considerations

No public confirmed substitute part numbers are provided in the source material. Engineers must consult official replacement guides or contact the manufacturer directly for valid cross-reference recommendations suitable for new designs.
