Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN612-80-24 is determined by the following critical parameters:

Primary Matching Criteria:

• Filter Type: Single Phase
• Configuration: Single Stage
• Voltage Rating: 250V AC
• Current Rating: 80 A
• Mounting Type: Chassis Mount
• Approval Agencies: CSA, ENEC, UR certification

Secondary Compatibility Factors:

• Operating Temperature Range: -25°C ~ 100°C
• RoHS Compliance Status
• REACH Compliance Status

The FN2410-80-34 qualifies as a substitute part because it maintains equivalence across all primary matching criteria. Both components are single-phase, single-stage filters rated for 80 A at 250V, chassis-mounted, and carry identical regulatory approvals. The primary distinction lies in termination style (threaded post versus terminal block) and operating frequency specification, which do not preclude substitution in applications where the FN2410-80-34's terminal block termination is mechanically compatible with the installation.

Parameter Comparison

Engineering Selection Recommendations

The FN2410-80-34 is the qualified substitute for the obsolete FN612-80-24 based on the following engineering criteria:

Regulatory and Compliance Alignment: Both components carry identical third-party approvals (CSA, ENEC, UR), ensuring equivalent compliance standing for applications requiring these certifications. The FN2410-80-34 maintains RoHS3 compliance, which exceeds the RoHS compliance of the original part.

Electrical Performance Equivalence: Identical voltage (250V AC), current (80 A), and temperature operating range (-25°C ~ 100°C) specifications ensure functional equivalence in the electrical domain. The FN2410-80-34 operates at 250Hz, which falls within the DC to 400Hz operating range of the FN612-80-24, confirming compatibility for frequency-dependent applications.

Procurement and Lifecycle Advantage: The FN2410-80-34 is classified as active product status with confirmed inventory availability (631 pcs), whereas the FN612-80-24 is obsolete. Selection of the FN2410-80-34 ensures long-term supply chain continuity and support.

Mechanical Integration Consideration: The primary design difference is termination style: the FN612-80-24 uses threaded post (M6) termination, while the FN2410-80-34 uses terminal block termination. Mechanical compatibility must be evaluated based on the specific installation's connection requirements and available mounting space.

Frequently Asked Questions (FAQ)

Q: Can the FN2410-80-34 directly replace the FN612-80-24 in all applications?

A: The FN2410-80-34 is electrically and functionally equivalent to the FN612-80-24 across all critical parameters (voltage, current, frequency range, temperature, and regulatory approvals). However, the termination style differs (terminal block versus threaded post M6). Direct replacement requires that the installation's connection interface is compatible with terminal block termination. Mechanical evaluation of the mounting and connection points is necessary before implementation.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: single-phase filter type, single-stage configuration, 250V AC voltage rating, 80 A current rating, chassis mount type, and CSA/ENEC/UR regulatory approvals. The FN2410-80-34 meets all these criteria, qualifying it as a substitute.

Q: Why is the FN612-80-24 listed as obsolete?

A: The FN612-80-24 is classified as obsolete by the manufacturer, indicating it is no longer in active production. The FN2410-80-34 represents the current-generation equivalent from Schaffner EMC Inc. for this application category.

Q: Are there any compliance or certification differences between these parts?

A: Both components carry identical third-party approvals (CSA, ENEC, UR). The FN2410-80-34 is ROHS3 compliant, which represents an updated compliance standard compared to the RoHS compliance of the FN612-80-24. Both are REACH unaffected.

Q: What is the difference between threaded post and terminal block termination?

A: Threaded post (M6) termination uses screw-down connections via M6 threaded studs, while terminal block termination uses plug-in or screw-down connections to a modular terminal block. The choice depends on the installation's wiring infrastructure and connection methodology. Terminal block termination typically offers faster connection/disconnection cycles.

Q: Is the inductance specification critical for substitution?

A: The FN612-80-24 specifies 200µH inductance. The FN2410-80-34 does not provide an inductance specification in the available data. If inductance is a critical parameter for your application, this specification gap should be clarified with the manufacturer before proceeding with substitution.

Q: What is the operating frequency difference between these parts?

A: The FN612-80-24 operates from DC to 400Hz, while the FN2410-80-34 operates at 250Hz. The FN2410-80-34's 250Hz specification falls within the broader range of the FN612-80-24, confirming compatibility for applications operating at or below 250Hz. Applications requiring operation above 250Hz should be evaluated against the FN2410-80-34's frequency specification.
