Procurement Notes

Verify the product status carefully before procurement, as this specific part number is listed as obsolete or end-of-life in available distributor records. Confirm availability through authorized channels or check for direct replacements from Murata's official documentation. Ensure the supplier provides genuine components with traceable origins to avoid counterfeit risks associated with discontinued items.

Selection Notes

Select this component only if the application specifically requires a third-order LC filter in a 1206 footprint with a 200mA current rating. Consider the obsolete status when planning long-term production cycles. Evaluate alternative active or passive solutions if supply chain stability is critical, ensuring any substitute matches the electrical characteristics and physical dimensions required by the PCB layout.

Part Context

This component belongs to Murata's EMIFIL series, which specializes in electromagnetic interference filters. The NFW31SP106X1E4L01 utilizes an LC network topology to provide attenuation across specific frequency bands. It is categorized under EMI/RFI filters, distinct from standard capacitors or inductors, serving primarily to suppress high-frequency noise in sensitive electronic systems.

Replacement Considerations

Public confirmed substitute part numbers are not explicitly documented in the provided source material due to the component's obsolete status. Consult Murata Electronics' official replacement guides or contact technical support directly for validated alternatives that meet the same electrical and mechanical specifications.
