FN612-30-10 Equivalent & Substitute Parts

Part Overview

The FN612-30-10 is a single-phase EMC/EMI line filter rated for 30 A at 250VAC with DC to 400Hz operating frequency range. This chassis-mount filter is designed for general-purpose applications requiring electromagnetic compatibility filtering. The FN612-30-10 is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical performance and mechanical compatibility while offering current product availability.

Substitute Part Grouping Explanation

The FN2020-30-08 qualifies as a direct substitute for the FN612-30-10 based on the following critical parameters:

• Identical electrical specifications: Both parts maintain 250VAC rating, 30 A current capacity, and DC ~ 400Hz operating frequency
• Matching filter configuration: Single-phase, single-stage topology ensures functional equivalence
• Identical mounting and thermal requirements: Both are chassis-mount units with -25°C ~ 100°C operating temperature range
• Equivalent regulatory compliance: Both hold CSA, ENEC, and UR approvals
• RoHS compliance: FN2020-30-08 is ROHS3 Compliant, meeting or exceeding the RoHS Compliant status of the original part

The primary difference is the termination style: FN612-30-10 uses threaded post (8-32) while FN2020-30-08 uses threaded post (M4). This represents a mechanical interface change that must be evaluated during integration. The FN2020-30-08 is an active product with current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The FN2020-30-08 is the designated substitute for the obsolete FN612-30-10. Both parts are manufactured by Schaffner EMC Inc. and maintain identical electrical ratings, frequency response, and thermal operating ranges. The FN2020-30-08 holds active product status with current inventory availability, addressing the obsolescence of the original part.

Both parts carry equivalent regulatory approvals (CSA, ENEC, UR) and maintain REACH compliance. The FN2020-30-08 achieves ROHS3 Compliant status, which exceeds the RoHS Compliant designation of the FN612-30-10.

The inductance values differ slightly (610µH versus 670µH), representing a 9.8% increase in the substitute part. This variance remains within acceptable tolerances for general-purpose EMC/EMI filtering applications where both parts share identical voltage, current, and frequency specifications.

The termination interface change from 8-32 threaded post to M4 threaded post requires mechanical redesign consideration during integration. This is the only parameter requiring design modification for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can FN2020-30-08 directly replace FN612-30-10 in existing designs?

A: Electrical and thermal specifications are identical, enabling functional substitution. The termination style change from 8-32 to M4 threaded post requires mechanical interface modification. No electrical redesign is necessary.

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

A: The FN2020-30-08 inductance of 670µH compared to the FN612-30-10 inductance of 610µH represents a 9.8% increase. Both values support the identical 250VAC, 30 A, DC ~ 400Hz specifications. This variance is acceptable for general-purpose EMC/EMI filtering applications.

Q: Are regulatory approvals equivalent between these parts?

A: Both parts hold identical approvals from CSA, ENEC, and UR. The FN2020-30-08 achieves ROHS3 Compliant status, which meets or exceeds the RoHS Compliant status of the FN612-30-10. REACH compliance is equivalent for both parts.

Q: What is the primary reason for substitution?

A: The FN612-30-10 is classified as obsolete. The FN2020-30-08 is an active product with current inventory availability, ensuring long-term procurement viability.

Q: Are there packaging differences between these parts?

A: The FN612-30-10 is supplied with standard packaging. The FN2020-30-08 is supplied in box packaging. Both are new original stock from Schaffner EMC Inc.
