Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN612-30-03 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Filter Type: Single Phase
• Configuration: Single Stage
• Voltage Rating: 250V AC
• Current Rating: 30A
• Frequency Range: DC ~ 400Hz
• Mounting Type: Chassis Mount
• Approval Agencies: CSA, ENEC, UR
• Operating Temperature Range: -25°C ~ 100°C
• RoHS Compliance Status

Allowable Variations:

• Termination Style (Terminal Block vs. Threaded Post)
• Inductance value (within component tolerance)
• Packaging format (Tray vs. Box)
• Series designation

The FN2020-30-08 meets all mandatory matching parameters and qualifies as a direct substitute despite differences in termination style and inductance specification.

Parameter Comparison

Engineering Selection Recommendations

The FN2020-30-08 is qualified as a substitute for the FN612-30-03 based on the following engineering criteria:

Electrical Equivalence: Both components maintain identical voltage, current, frequency, and temperature specifications. The inductance difference (610µH vs. 670µH) represents a 9.8% variance within acceptable component tolerance ranges for EMC filter applications.

Regulatory Compliance: Both parts carry identical approval certifications (CSA, ENEC, UR) and maintain RoHS compliance status. The FN2020-30-08 meets ROHS3 requirements, representing an enhanced compliance posture.

Supply Chain Status: The FN612-30-03 is obsolete with limited remaining inventory (1004 pcs). The FN2020-30-08 is active production with higher inventory availability (1054 pcs), ensuring long-term supply continuity.

Design Integration Consideration: The primary difference is termination style. The FN612-30-03 uses terminal block connections, while the FN2020-30-08 uses M4 threaded posts. Circuit board or chassis integration must accommodate this mechanical difference during substitution.

Frequently Asked Questions (FAQ)

Q: Can the FN2020-30-08 directly replace the FN612-30-03 in existing designs?

A: Electrical and functional replacement is confirmed. Mechanical integration requires verification of the termination interface. Terminal block connections must be adapted to M4 threaded post connections, or alternative mounting hardware must be specified.

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

A: The FN2020-30-08 inductance (670µH) is 9.8% higher than the FN612-30-03 (610µH). Both values fall within standard component tolerance ranges. EMC filtering performance remains equivalent across the specified frequency range (DC ~ 400Hz).

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

A: Both parts carry identical approval certifications (CSA, ENEC, UR). The FN2020-30-08 meets ROHS3 compliance, which is a superset of RoHS requirements. No compliance degradation occurs with substitution.

Q: Why is the FN612-30-03 listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. The FN2020-30-08 represents the current production equivalent within the Schaffner EMC Inc. product line.

Q: What packaging differences exist between these parts?

A: The FN612-30-03 is supplied in Tray packaging, while the FN2020-30-08 is supplied in Box packaging. This difference affects storage, handling, and inventory management but does not impact electrical or mechanical performance.

Q: Are both parts suitable for general-purpose applications?

A: Yes. Both the FN612-30-03 and FN2020-30-08 are rated for general-purpose applications with identical voltage, current, frequency, and temperature specifications.
