RF Transceiver Modules And Modems Procurement Notes

This component is officially marked as obsolete and no longer manufactured by Microchip Technology. Procurement must rely on existing stock or secondary market channels. Verify part authenticity carefully due to potential availability of refurbished units. Confirm firmware version compatibility with existing system designs before acquisition. Check recent Product Change Notifications for any historical specification variations affecting integration.

RF Transceiver Modules And Modems Selection Notes

Engineers should evaluate the RN4678-V/RM122 as the recommended replacement due to the RN41N-I/RM's discontinued status. Consider upgrading to newer Bluetooth standards if future-proofing is required. Ensure that the target application does not mandate specific legacy protocol support exclusively found in v2.1 modules. Assess thermal management needs given the SMD package and operational current draw.

RF Transceiver Modules And Modems Part Context

The RN41 series represents Microchip's entry into compact Bluetooth solutions for embedded systems. The RN41N variant specifically denotes industrial-grade temperature ranges compared to commercial counterparts. This module simplifies wireless integration by combining the radio and baseband processing in a single surface-mount footprint, reducing design complexity for developers.

RF Transceiver Modules And Modems Replacement Considerations

Microchip recommends the RN4678-V/RM122 as the direct substitute. The replacement offers updated Bluetooth specifications while maintaining similar form factor constraints. Designers must verify pinout compatibility and software stack migration requirements when transitioning from the RN41N platform.
