Procurement Notes

Verify end-of-life status carefully as this component is marked obsolete by the manufacturer. Confirm current availability through authorized distributors, noting that stock levels may be limited. Ensure compatibility with existing reference designs before procurement.

Selection Notes

Select this model specifically for 868MHz regional requirements in LoRaWAN deployments. Consider its integration with SX1250 or SX1255 front-ends for optimal sensitivity. Evaluate thermal management needs despite simplified design benefits compared to previous generations.

Part Context

This component is part of the SX1302 family, designed as a next-generation digital baseband chip for gateways. It aims to reduce current consumption and material costs while handling increased traffic volume. The SX1302C868GW1 variant is specifically tuned for the 868MHz frequency band.

Replacement Considerations

No public confirmed substitute part numbers are available. As the component is obsolete, alternative solutions require system redesign or evaluation of newer Semtech gateway chips.
