Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN612B-10-06 is determined by strict equivalence across the following critical parameters:

• Voltage Rating: 250VAC (exact match required)
• Current Rating: 10A (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 Agencies: CSA, ENEC, UR certifications (must be maintained)

The FN2020B-10-06 meets all critical electrical and mechanical parameters for direct substitution. Both components are manufactured by Schaffner EMC Inc. and share identical voltage, current, frequency, mounting, and termination specifications. The primary difference is inductance value (450µH vs. 800µH) and product status (obsolete vs. active).

Parameter Comparison

Engineering Selection Recommendations

The FN2020B-10-06 is the direct substitute for the obsolete FN612B-10-06. Both components maintain identical electrical ratings (250VAC, 10A, DC~400Hz), mechanical configuration (chassis mount, quick connect), and regulatory certifications (CSA, ENEC, UR). The FN2020B-10-06 is currently in active production status with 828 units available in inventory, ensuring supply continuity.

The inductance difference (800µH vs. 450µH) reflects design evolution within the FN series. The higher inductance of the FN2020B-10-06 provides enhanced filtering characteristics while maintaining full compatibility with the original electrical and mechanical interface requirements.

Frequently Asked Questions (FAQ)

Q: Can the FN2020B-10-06 directly replace the FN612B-10-06 in existing installations?

A: Yes. Both components share identical voltage ratings (250VAC), current ratings (10A), operating frequency range (DC~400Hz), mounting type (chassis mount), and termination style (quick connect). All regulatory certifications (CSA, ENEC, UR) are maintained.

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

A: The FN2020B-10-06 features 800µH inductance compared to 450µH in the FN612B-10-06. This represents a design improvement in the FN series. Both values are within the acceptable range for single-stage EMC/EMI filtering at the specified electrical parameters.

Q: Why is the FN612B-10-06 listed as obsolete?

A: The FN612B-10-06 has been superseded by the FN2020B-10-06 within Schaffner's product line. The FN2020 series represents the current generation of single-phase chassis-mount line filters with equivalent electrical performance and enhanced design characteristics.

Q: Are there packaging differences between these components?

A: The FN612B-10-06 is supplied with standard packaging, while the FN2020B-10-06 is supplied in trays. Both are suitable for chassis-mount installation with quick-connect termination.

Q: Do both parts meet current RoHS requirements?

A: Yes. The FN612B-10-06 is RoHS Compliant, and the FN2020B-10-06 is ROHS3 Compliant, ensuring compliance with current and future environmental regulations.
