Substitute Part Grouping Explanation

Substitution eligibility for the FN612-20-06 is determined by the following critical parameters:

• Voltage rating: 250VAC (exact match required)
• Current capacity: 20A (exact match required)
• Operating frequency range: DC ~ 400Hz (exact match required)
• Filter topology: Single Phase, Single Stage (exact match required)
• Mounting configuration: Chassis Mount (exact match required)
• Termination interface: Quick Connect (exact match required)
• Regulatory compliance: CSA, ENEC, UR certifications (maintained or equivalent)
• Temperature operating range: -25°C ~ 100°C (exact match required)

The FN2020-20-06 meets all substitution criteria, maintaining identical electrical specifications, mechanical interface compatibility, and regulatory approvals while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The FN2020-20-06 is the direct substitute for the obsolete FN612-20-06. Both components are manufactured by Schaffner EMC Inc. and maintain identical electrical ratings, mechanical interfaces, and regulatory certifications required for 250VAC, 20A single-phase EMC filtering applications.

The FN2020-20-06 offers the advantage of active product status, ensuring continued availability and support. The component carries ROHS3 compliance, meeting current environmental standards. The inductance specification differs (600µH versus 480µH), reflecting design evolution within the FN 2020 series while maintaining functional compatibility for general-purpose filtering applications.

Selection of the FN2020-20-06 is appropriate for new designs, system upgrades, and replacement of obsolete FN612-20-06 units in existing installations where the electrical and mechanical interface requirements remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the FN2020-20-06 directly replace the FN612-20-06 in existing installations?

A: Yes. Both components share identical voltage ratings (250VAC), current capacity (20A), operating frequency range (DC ~ 400Hz), mounting type (Chassis Mount), and termination style (Quick Connect). The mechanical and electrical interfaces are compatible.

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

A: The FN2020-20-06 specifies 600µH inductance compared to 480µH in the FN612-20-06. This difference reflects design improvements in the FN 2020 series. Both values are within acceptable ranges for single-stage EMC filtering at the specified voltage and current ratings.

Q: Are the regulatory certifications equivalent?

A: Yes. Both parts carry identical approvals from CSA, ENEC, and UR, confirming compliance with the same safety and electromagnetic compatibility standards.

Q: Why is the FN612-20-06 listed as obsolete?

A: The FN612-20-06 has been superseded by the FN2020-20-06 within Schaffner's product line. The FN2020 series represents the current generation of single-phase chassis-mount EMC filters at this specification level.

Q: What packaging differences exist between these parts?

A: The FN612-20-06 is supplied with standard packaging, while the FN2020-20-06 is supplied in Tray packaging. Both packaging formats are suitable for component handling and storage in industrial applications.

Q: Are both parts RoHS compliant?

A: Yes. The FN612-20-06 is RoHS Compliant, and the FN2020-20-06 is ROHS3 Compliant, meeting current environmental regulations for electronic components.
