FN660-16-03 Equivalent & Substitute Parts

Part Overview

The FN660-16-03 is a single-phase EMC/EMI line filter manufactured by Schaffner EMC Inc., rated for 250VAC at 16A with DC to 400Hz operating frequency. This chassis-mount filter features a two-stage configuration with terminal block termination and is designed for general-purpose applications requiring electromagnetic compatibility filtering.

The FN660-16-03 is classified as obsolete. Identifying suitable substitute components is necessary to maintain system availability and ensure continued compliance with electromagnetic compatibility standards in applications where this filter was originally specified.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN660-16-03 is based on electrical and mechanical parameter alignment within the Schaffner EMC line filter product family. The following parameters determine substitution eligibility:

• Voltage rating: 250VAC (exact match required)
• Current rating: 16A (exact match required)
• Operating frequency range: DC ~ 400Hz (exact match required)
• Filter type: Single Phase (exact match required)
• Configuration: Two Stage (exact match required)
• Mounting type: Chassis Mount (exact match required)
• Operating temperature range: -25°C ~ 100°C (exact match required)

The FN2060-16-06 meets all core electrical and mechanical requirements. Variations in inductance value (650µH vs. 440µH), termination style (Quick Connect vs. Terminal Block), and packaging format represent design improvements in the successor series and do not preclude functional substitution in applications where the original filter was specified.

Parameter Comparison

Engineering Selection Recommendations

The FN2060-16-06 is the active production substitute for the obsolete FN660-16-03. Both components share identical electrical ratings (250VAC, 16A, DC ~ 400Hz) and mechanical specifications (single-phase, two-stage, chassis-mount configuration).

The FN2060-16-06 carries expanded regulatory approvals including CE marking in addition to CSA, ENEC, and UR certifications held by the original part. Both components maintain RoHS compliance and REACH unaffected status.

The primary design differences are termination style (Quick Connect vs. Terminal Block) and inductance specification (650µH vs. 440µH). The higher inductance value in the FN2060-16-06 provides enhanced filtering performance. Termination style change requires mechanical interface verification during integration.

Frequently Asked Questions (FAQ)

Q: Can the FN2060-16-06 directly replace the FN660-16-03 in existing applications?

A: The FN2060-16-06 meets all core electrical and mechanical requirements. However, the termination style differs (Quick Connect vs. Terminal Block), requiring mechanical interface verification. The higher inductance value (650µH vs. 440µH) provides improved filtering characteristics and does not create compatibility issues.

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

A: The FN2060-16-06 specifies 650µH inductance compared to 440µH in the FN660-16-03. Higher inductance provides greater attenuation of high-frequency noise. This represents a performance improvement and does not restrict substitution.

Q: Are regulatory certifications equivalent between these parts?

A: The FN2060-16-06 includes CE marking in addition to CSA, ENEC, and UR certifications. The original FN660-16-03 holds CSA, ENEC, and UR approvals. Both maintain RoHS compliance and REACH unaffected status. The expanded certifications on the FN2060-16-06 provide broader regulatory coverage.

Q: What packaging differences exist between these components?

A: The FN660-16-03 uses standard packaging, while the FN2060-16-06 is supplied in tray packaging. This difference affects handling and storage but does not impact electrical or mechanical performance.

Q: Why is the FN660-16-03 classified as obsolete?

A: The FN660-16-03 has been superseded by the FN2060-16-06 within Schaffner's product line. The newer series offers improved filtering performance, expanded regulatory certifications, and modern termination options while maintaining backward compatibility with the original electrical specifications.
