Procurement Notes
Verify the manufacturer designation as TE Connectivity / Schaffner on official datasheets. Confirm RoHS compliance status and specific medical certification requirements against the latest product documentation. Ensure the part number matches the exact 1.6A rating and 250VAC specification to avoid functional mismatches in sensitive medical circuits.
Selection Notes
Select this component when medical-grade EMC performance is required at a low cost point. The FN402B series is optimized for single-phase AC inputs up to 1.6A. Consider the through-hole solder pin interface for direct PCB integration. Evaluate leakage current specifications if patient safety isolation is critical for the target application design.
Part Context
This filter is part of the broader FN402 family from Schaffner EMC Inc., a division of TE Connectivity. The series provides standardized electromagnetic interference filtering solutions. The FN402B variant specifically targets medical device manufacturers requiring compliant, compact, and cost-effective power line filters for single-phase applications.
Replacement Considerations
Compatible substitutes within the same series include FN402B-1-02 and FN402B-2.5-02. These parts share the same medical-purpose design philosophy and mounting style but differ in current ratings. Verify electrical parameters match the system requirements before substitution.
