Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN612-6-06 is determined by strict equivalence across the following critical parameters:

• Voltage Rating: 250VAC (exact match required)
• Current Rating: 6A (exact match required)
• Filter Type: Single Phase (exact match required)
• Configuration: Single Stage (exact match required)
• Frequency Range: DC ~ 400Hz (exact match required)
• Mounting Type: Chassis Mount (exact match required)
• Termination Style: Quick Connect (exact match required)
• Approval Certifications: CSA, ENEC, UR (must be present)

The FN2020-6-06 meets all substitution criteria as an active product from the same manufacturer with identical electrical specifications and mechanical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

The FN2020-6-06 is the direct substitute for the obsolete FN612-6-06. Both components are manufactured by Schaffner EMC Inc. and maintain identical electrical ratings, frequency response, voltage specifications, current capacity, and mechanical interface characteristics. The FN2020-6-06 holds active product status with current manufacturing support and availability (1353 pcs in stock versus 855 pcs for the obsolete FN612-6-06).

Both components carry equivalent regulatory approvals (CSA, ENEC, UR) and RoHS compliance certifications, ensuring compatibility with current environmental and safety standards. The inductance difference (750µH versus 1mH) reflects design evolution within the same functional class and does not affect substitution validity for applications requiring the specified electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can the FN2020-6-06 directly replace the FN612-6-06 in existing installations?

A: Yes. Both components share identical voltage ratings (250VAC), current capacity (6A), frequency range (DC ~ 400Hz), mounting configuration (chassis mount), and termination style (quick connect). All regulatory approvals and operating temperature ranges are equivalent.

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

A: The FN612-6-06 specifies 750µH inductance while the FN2020-6-06 specifies 1mH. Both values fall within acceptable ranges for single-stage EMC/EMI filtering at the specified electrical parameters. This difference represents design refinement between product generations and does not prevent functional substitution.

Q: Why is the FN612-6-06 listed as obsolete?

A: The FN612-6-06 belongs to an earlier product series (FN 612) that has been superseded by the FN 2020 series. The FN2020-6-06 represents the current-generation equivalent with active manufacturing and supply chain support.

Q: Are there packaging differences between these components?

A: The FN612-6-06 uses standard packaging while the FN2020-6-06 is supplied in trays. Both packaging formats are suitable for chassis-mount installation and do not affect electrical or mechanical compatibility.

Q: Do both components meet current compliance standards?

A: Yes. Both the FN612-6-06 and FN2020-6-06 are RoHS compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.
