Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN612-3-06 is based on the following critical parameters that must remain consistent:

• Voltage Rating: 250VAC (required match)
• Current Rating: 3A (required match)
• Filter Type: Single Phase (required match)
• Configuration: Single Stage (required match)
• Operating Frequency: DC ~ 400Hz (required match)
• Mounting Type: Chassis Mount (required match)
• Termination Style: Quick Connect (required match)
• Approval Agencies: CSA, ENEC, UR (required match)

The FN2020-3-06 meets all critical substitution criteria. While inductance differs slightly (2.5 mH versus 2 mH) and packaging differs (Tray versus original specification), the electrical and mechanical interface parameters remain compatible for direct substitution in applications designed for the FN612-3-06.

Parameter Comparison

Engineering Selection Recommendations

The FN2020-3-06 is the direct substitute for the obsolete FN612-3-06. Both components are manufactured by Schaffner EMC Inc. and share identical electrical ratings, frequency response, and mechanical interface specifications.

The FN2020-3-06 offers the advantage of active product status, ensuring ongoing availability and support. The component maintains all required regulatory certifications (CSA, ENEC, UR) and meets current RoHS3 compliance requirements. The inductance variance (2.5 mH versus 2 mH) represents a 25% increase and should be evaluated within the context of the specific application's filtering requirements.

Frequently Asked Questions (FAQ)

Q: Can the FN2020-3-06 be used as a direct replacement for the FN612-3-06?

A: Yes. Both components share identical voltage ratings (250VAC), current ratings (3A), operating frequency range (DC ~ 400Hz), mounting type (Chassis Mount), and termination style (Quick Connect). All regulatory certifications match.

Q: What is the difference in inductance between these parts?

A: The FN612-3-06 has 2 mH inductance, while the FN2020-3-06 has 2.5 mH inductance. This 0.5 mH difference may affect filtering characteristics in frequency-sensitive applications and should be evaluated against circuit requirements.

Q: Why is the FN612-3-06 listed as obsolete?

A: The FN612-3-06 has been discontinued by the manufacturer. The FN2020-3-06 represents the current-generation equivalent within the Schaffner EMC Inc. product line.

Q: Are the packaging formats interchangeable?

A: The FN612-3-06 original packaging specification differs from the FN2020-3-06 Tray packaging. Packaging format does not affect electrical or mechanical compatibility for component installation.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the FN612-3-06 and FN2020-3-06 carry CSA, ENEC, and UR approvals. The FN2020-3-06 additionally meets ROHS3 compliance requirements.
