Procurement Notes

Verify the specific manufacturing status of this part number before procurement planning. Official documentation indicates that the RN222-1-02-33 may be obsolete or no longer manufactured by TE Connectivity / Schaffner. Confirm availability through authorized distributors or identify approved replacement components from the same product family to ensure supply chain continuity.

Selection Notes

Select this component for applications requiring 33 mH common mode inductance at 1 A current ratings. Ensure the PCB layout accommodates the specified vertical footprint dimensions. Verify thermal management requirements against the -40°C to +100°C operating range. Confirm compatibility with through-hole assembly processes and check for any specific safety certifications required for the target market.

Part Context

This component belongs to the RN series of common mode chokes manufactured by Schaffner EMC Inc., now part of TE Connectivity. The RN series is characterized by vertical mounting options and ferrite core technology. These chokes are engineered for general-purpose EMI/EMC filtering in single-phase applications, providing attenuation for noise conducted along power lines.

Replacement Considerations

Public records indicate this part number is obsolete. Consider substitutes such as RN222-1-02-33M or other variants within the RN222 series that match the 33 mH inductance and 1 A current specifications. Verify pinout and dimensional compatibility before substitution.
