Procurement Notes

Verify the specific suffix designation against official TE Connectivity or Schaffner documentation to ensure exact electrical characteristics match the design requirements. Confirm that the package dimensions and pin configuration align with the target PCB layout. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when a compact, vertically mounted common mode choke is required for low-current applications up to 1.5 A. Ensure the operating environment stays within the specified -40°C to +100°C thermal limits. Verify that the 1.6 mH inductance value meets the necessary EMI suppression criteria for the specific frequency spectrum of the application.

Part Context

This component belongs to the RN series of EMC chokes manufactured by TE Connectivity / Schaffner. The series offers various inductance and current ratings tailored for different power line filtering needs. The RN102 variant specifically addresses space-constrained designs requiring vertical PCB integration while maintaining standard through-hole compatibility for automated assembly processes.

Replacement Considerations

The part number RN102-1.5-02-1M6 serves as a confirmed substitute identifier for this component. Verify mechanical footprint compatibility and electrical parameter equivalence before implementing any alternative sourcing strategies.
