Substitute Part Grouping Explanation

The FN2060-20-06 qualifies as a direct substitute for the FN660-20-06 based on the following critical parameters:

• Voltage rating: Both rated for 250V AC
• Current capacity: Both rated for 20A
• Filter type: Both are single-phase configurations
• Configuration: Both employ two-stage design
• Operating frequency: Both support DC ~ 400Hz
• Mounting: Both are chassis-mount
• Termination: Both use quick connect
• Temperature range: Both operate -25°C ~ 100°C
• Application class: Both designated for general-purpose use

The FN2060-20-06 represents an active product from the same manufacturer, providing functional and electrical equivalence to the obsolete FN660-20-06.

Parameter Comparison

Engineering Selection Recommendations

The FN2060-20-06 is the appropriate substitute for the obsolete FN660-20-06. Both components share identical electrical and mechanical specifications across all critical parameters: voltage rating, current capacity, filter topology, operating frequency range, mounting configuration, and termination method.

The FN2060-20-06 offers enhanced regulatory compliance with CE certification in addition to CSA, ENEC, and UR approvals. The component maintains ROHS3 compliance status and is currently in active production, ensuring long-term availability and supply chain continuity.

The inductance differential (480µH versus 600µH) reflects design optimization within the FN 2060 series and does not affect functional substitution for general-purpose EMC/EMI filtering applications.

Frequently Asked Questions (FAQ)

Q: Can the FN2060-20-06 directly replace the FN660-20-06 in existing applications?

A: Yes. Both components are rated identically for 250VAC, 20A, single-phase, two-stage configuration with quick connect termination and chassis mounting. Electrical and mechanical compatibility is established across all specified parameters.

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

A: The FN2060-20-06 specifies 600µH inductance compared to 480µH in the FN660-20-06. This represents a design variation within the FN 2060 series and does not prevent functional substitution for general-purpose applications within the specified operating parameters.

Q: Are there regulatory compliance differences between these parts?

A: The FN2060-20-06 includes CE certification in addition to CSA, ENEC, and UR approvals held by the FN660-20-06. Both maintain equivalent RoHS compliance status (RoHS Compliant and ROHS3 Compliant respectively). The FN2060-20-06 represents current regulatory standards.

Q: Why is the FN660-20-06 classified as obsolete?

A: The FN660-20-06 has been superseded by the FN2060-20-06 within Schaffner EMC Inc.'s product portfolio. The FN2060 series represents the current active product line for this filter class.

Q: What packaging differences exist between these parts?

A: The FN660-20-06 is supplied in standard packaging, while the FN2060-20-06 is supplied in tray packaging. Both packaging formats are suitable for component handling and installation in chassis-mount applications.
