Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN612-20-10 is determined by strict equivalence across the following critical parameters:

• Filter Type & Configuration: Single Phase, Single Stage topology must be maintained
• Electrical Ratings: 250VAC, 20A current capacity, and DC ~ 400Hz frequency range are mandatory
• Mounting & Termination: Chassis mount configuration with threaded post termination
• Environmental & Compliance: Operating temperature range -25°C ~ 100°C and regulatory approvals (CSA, ENEC, UR)
• RoHS Compliance: Both parts must meet RoHS requirements

The FN2020-20-08 qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. Differences in inductance (480µH vs. 600µH) and termination post size (8-32 vs. M4) represent acceptable variations within the filter's functional specification for general-purpose EMC/EMI applications.

Parameter Comparison

Engineering Selection Recommendations

The FN2020-20-08 is the qualified substitute for the obsolete FN612-20-10. Both components maintain identical electrical performance specifications: 250VAC, 20A capacity, single-phase single-stage configuration, and DC to 400Hz operating range. Regulatory compliance is equivalent, with both parts holding CSA, ENEC, and UR approvals.

The FN2020-20-08 offers the advantage of active product status with higher inventory availability (1251 pcs vs. 695 pcs), ensuring supply chain continuity. The component meets current RoHS3 compliance requirements, exceeding the RoHS compliance of the original part. Termination post geometry differs (M4 vs. 8-32), requiring mechanical interface verification during integration. Inductance variation (600µH vs. 480µH) remains within acceptable tolerance for general-purpose EMC/EMI filtering applications.

Frequently Asked Questions (FAQ)

Q: Can the FN2020-20-08 directly replace the FN612-20-10 in existing designs?

A: Electrical and functional compatibility is confirmed across all critical parameters. Mechanical integration requires verification of the threaded post interface, as termination geometry differs (M4 vs. 8-32 UNC). Mounting hole patterns and chassis cutout dimensions must be confirmed before installation.

Q: What is the significance of the inductance difference between these parts?

A: The FN2020-20-08 exhibits 600µH inductance compared to 480µH in the FN612-20-10. Both values are within the functional specification for single-stage EMC/EMI filtering at 20A, 250VAC. Filter attenuation characteristics may vary slightly; application-specific EMI performance should be evaluated if critical frequency bands are involved.

Q: Why is the FN612-20-10 listed as obsolete?

A: The FN612-20-10 has reached end-of-life status. The FN2020-20-08 represents the current-generation equivalent from Schaffner EMC Inc., offering improved compliance status and active manufacturing support.

Q: Are there packaging differences between these parts?

A: The FN612-20-10 is supplied without specified packaging, while the FN2020-20-08 is packaged in trays. This difference affects logistics and handling but does not impact electrical or mechanical performance.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both components hold CSA, ENEC, and UR approvals. The FN2020-20-08 additionally meets ROHS3 compliance, representing current environmental standards. Both parts are REACH Unaffected.
