RF Transceiver ICS Procurement Notes

This component is officially End-of-Life (EOL). Distribution channels indicate that the manufacturer has ceased production, and standard supply chains are unavailable. Procurement efforts should focus exclusively on verified surplus stock or authorized replacement alternatives. Verify RoHS compliance status through official documentation before integration into new designs.

RF Transceiver ICS Selection Notes

Select this part only for legacy system maintenance or specific design-in requirements where its exact pinout and electrical characteristics are mandatory. Due to its discontinued status, engineers must evaluate long-term availability risks. Consider the 28-VFQFN package constraints and verify that the supported modulation types meet the target application's protocol specifications.

RF Transceiver ICS Part Context

The AX5042-1-TA05 belongs to the AX5042 series of low-power RF transceivers. It is engineered for general-purpose sub-1GHz connectivity, targeting IoT and industrial automation sectors.
