Procurement Notes
This component is officially listed as obsolete by the manufacturer. Availability is restricted to existing stock or secondary market sources. Verify RoHS compliance status and specific lot dates when sourcing from distributors. Ensure compatibility with legacy designs due to discontinued production status.
Selection Notes
Select this part for simple point-to-point transmission links requiring minimal external components. It is suitable for applications where only transmitting functionality is needed, rather than full duplex communication. Consider the fixed 2.4 GHz frequency and GFSK protocol constraints during system architecture design.
Part Context
The NRF2402G belongs to the nRF2402 family of wireless transceivers from Nordic Semiconductor. It serves as a dedicated transmitter solution, complementing other chips in the ecosystem that may handle reception or more complex protocol stacks. It represents an earlier generation of Nordic's wireless connectivity portfolio.
Replacement Considerations
No direct public substitute part numbers are confirmed in the provided documentation. As the product is obsolete, engineers must evaluate newer Nordic Semiconductor platforms or third-party alternatives based on pin compatibility and RF performance requirements.
