FN660-20-10 Equivalent & Substitute Parts

Part Overview

The FN660-20-10 is a single-phase EMC/EMI line filter rated for 250VAC at 20A with a two-stage configuration and chassis mount design. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations. The FN660-20-10 features threaded post termination (8-32) and operates across DC to 400Hz frequency range, suitable for general-purpose filtering applications.

Key Parameters

Substitute Part Grouping Explanation

The FN2060-20-08 qualifies as a functional substitute for the FN660-20-10 based on the following critical parameters:

• Voltage rating: Both rated for 250V AC
• Current capacity: Both rated for 20A
• Filter type and configuration: Both are single-phase, two-stage filters
• Operating frequency: Both operate DC ~ 400Hz
• Mounting: Both are chassis mount
• Operating temperature range: Both operate -25°C ~ 100°C
• Applications: Both designated for general-purpose use

The primary differences are termination style (8-32 vs. M4 threaded posts), inductance specification (480µH vs. 600µH), and product status (obsolete vs. active). The FN2060-20-08 represents an active product line successor with enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The FN2060-20-08 is the designated substitute for the obsolete FN660-20-10. Selection of the FN2060-20-08 is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• Enhanced regulatory compliance including CE certification in addition to CSA, ENEC, and UR approvals
• ROHS3 compliance exceeding the RoHS Compliant status of the original part
• Identical electrical performance across voltage, current, frequency, and temperature specifications
• Equivalent filtering configuration and mounting methodology

Physical integration requires accommodation for M4 threaded post termination in place of 8-32 specification. The increased inductance value (600µH vs. 480µH) provides enhanced filtering characteristics within the same operational envelope.

Frequently Asked Questions (FAQ)

Q: Can the FN2060-20-08 directly replace the FN660-20-10 in existing installations?

A: Electrical compatibility is confirmed across all critical parameters. Physical installation requires verification of termination compatibility, as the FN2060-20-08 uses M4 threaded posts while the FN660-20-10 uses 8-32 specification. Mounting hardware adjustment may be necessary.

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

A: The FN2060-20-08 specifies 600µH inductance compared to 480µH for the FN660-20-10. Both values operate within the filtering requirements for single-phase, two-stage EMC/EMI applications at 20A and 250VAC. The higher inductance in the substitute provides increased filtering effectiveness.

Q: Why is the FN660-20-10 classified as obsolete?

A: The FN660-20-10 has been superseded by the FN2060-20-08 within the Schaffner product line. The FN2060 series represents current production with enhanced certifications and compliance standards.

Q: Are there packaging differences between these parts?

A: The FN660-20-10 is supplied with standard packaging, while the FN2060-20-08 is supplied in tray packaging. This difference does not affect electrical or mechanical performance.

Q: What certifications does the FN2060-20-08 carry?

A: The FN2060-20-08 holds CE, CSA, ENEC, and UR certifications, providing broader regulatory coverage than the FN660-20-10 which carries CSA, ENEC, and UR certifications.
