RF Transceiver Modules And Modems Procurement Notes

This component is officially listed as obsolete and no longer manufactured by Silicon Labs. Procurement should focus on verified replacement parts such as the BT122-A-V2R. Verify compatibility with existing firmware and hardware designs before transitioning to alternative modules. Check manufacturer documentation for end-of-life notices and recommended design-in alternatives to ensure long-term supply chain stability.

RF Transceiver Modules And Modems Selection Notes

Select this module only for legacy system maintenance or specific historical design requirements due to its discontinued status. Evaluate the BT122-A-V2R as the primary manufacturer-recommended substitute. Consider interface compatibility, pinout differences, and firmware migration efforts when replacing obsolete components. Ensure that the new selection meets all original performance specifications regarding power consumption, range, and protocol support.

RF Transceiver Modules And Modems Part Context

The WT12 series represents Silicon Labs' earlier generation of Bluetooth modules based on the BlueCore platform. These modules were widely used in embedded systems requiring reliable short-range wireless communication. The WT12-A-AI56IAPC specifically denotes a variant with defined interface and antenna configurations. This product line has been succeeded by newer generations offering enhanced performance and integration capabilities.

RF Transceiver Modules And Modems Replacement Considerations

The BT122-A-V2R is the manufacturer-recommended replacement for the WT12-A-AI56IAPC. Verify mechanical footprint and electrical parameter alignment during substitution. Review updated datasheets for any changes in interface protocols or power management features compared to the obsolete WT12 model.
