Key Parameters

Substitute Part Grouping Explanation

The FN2060B-16-06 qualifies as a direct substitute for the FN660B-16-06 based on the following critical parameters:

• Voltage rating: Both rated for 250VAC
• Current capacity: Both rated for 16A
• Operating frequency: Both support DC ~ 400Hz
• Filter type: Both are single-phase filters
• Configuration: Both feature two-stage design
• Mounting: Both are chassis-mount
• Termination: Both use quick-connect termination
• Temperature range: Both operate from -25°C to 100°C
• Application category: Both designated for general-purpose use

The FN2060B-16-06 represents an active product from the same manufacturer with identical electrical and mechanical specifications for the core filtering function.

Parameter Comparison

Engineering Selection Recommendations

The FN2060B-16-06 is the appropriate substitute for the obsolete FN660B-16-06. Both components meet identical electrical and mechanical requirements for 250VAC, 16A single-phase EMC filtering applications.

The FN2060B-16-06 offers the following advantages for new designs and replacements:

• Active product status ensures ongoing availability and supply chain continuity
• Enhanced compliance certifications including CE marking in addition to CSA, ENEC, and UR approvals
• ROHS3 compliance provides alignment with current regulatory requirements
• Higher inductance value (650µH versus 440µH) provides improved filtering performance in the specified frequency range

The inductance difference does not affect substitution eligibility, as both values fall within acceptable parameters for general-purpose EMC filtering at the specified voltage and current ratings.

Frequently Asked Questions (FAQ)

Q: Can the FN2060B-16-06 directly replace the FN660B-16-06 in existing applications?

A: Yes. Both components share identical voltage (250VAC), current (16A), frequency (DC ~ 400Hz), mounting (chassis), and termination (quick-connect) specifications. The FN2060B-16-06 is electrically and mechanically compatible for direct substitution.

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

A: The FN2060B-16-06 has 650µH inductance compared to 440µH in the FN660B-16-06. Both values are appropriate for single-phase EMC filtering in the DC to 400Hz frequency range. The higher inductance in the substitute provides enhanced attenuation characteristics without affecting compatibility with the specified electrical parameters.

Q: Why is the FN660B-16-06 listed as obsolete?

A: The FN660B-16-06 has been discontinued by the manufacturer. The FN2060B-16-06 from the FN 2060 series represents the current active product line replacement with equivalent functional specifications.

Q: Are there packaging differences between these parts?

A: The FN660B-16-06 uses standard packaging, while the FN2060B-16-06 is supplied in tray packaging. Both are suitable for chassis-mount installation and do not affect electrical performance or substitution compatibility.

Q: What compliance certifications apply to the FN2060B-16-06?

A: The FN2060B-16-06 carries CE, CSA, ENEC, and UR approvals. It meets ROHS3 compliance requirements, providing broader regulatory coverage than the obsolete FN660B-16-06.
