FN670-3-06 Equivalent & Substitute Parts

Part Overview

The FN670-3-06 is a single-phase EMC/EMI line filter manufactured by Schaffner EMC Inc., rated for 250VAC at 3A with a two-stage configuration and quick connect termination. This chassis-mount filter is designed for general-purpose applications operating across DC to 400Hz frequency range. The FN670-3-06 is classified as obsolete, making identification of active equivalent alternatives necessary for ongoing procurement and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN670-3-06 is determined by the following core parameters:

• Filter Type: Single Phase
• Configuration: Two Stage
• Current Rating: 3 A
• Frequency Range: DC ~ 400Hz
• Mounting Type: Chassis Mount
• Termination Style: Quick Connect

All three substitute parts (FN2060-3-06, FN2070-3-06, FN2090-3-06) maintain these core electrical and mechanical specifications. The primary differences among substitutes relate to voltage rating capability, inductance values, operating temperature ranges, and product status (all substitutes are active versus the obsolete main part).

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status with Schaffner EMC Inc., ensuring ongoing availability and support. Selection among FN2060-3-06, FN2070-3-06, and FN2090-3-06 depends on application voltage requirements and compliance certifications:

FN2060-3-06 is suitable for 250VAC-only applications and provides the lowest inductance value (2.5mH) among the substitutes. This part carries CE, CSA, ENEC, and UR certifications.

FN2070-3-06 supports dual voltage operation (110V and 250VAC) with inductance of 9.8mH, closest to the original FN670-3-06 specification of 12.2mH. Certifications include CSA, ENEC, and UR.

FN2090-3-06 also supports dual voltage operation (110V and 250VAC) with the highest inductance value (14mH) and includes CE certification in addition to CSA, ENEC, and UR. Operating temperature range extends to -20°C minimum.

All substitutes are ROHS3 compliant and maintain the same mounting and termination specifications as the original part.

Frequently Asked Questions (FAQ)

Q: Can FN2060-3-06 replace FN670-3-06 in all applications?

A: FN2060-3-06 is compatible with applications requiring 250VAC operation only. The inductance difference (2.5mH versus 12.2mH) may affect filtering characteristics in specific EMI/EMC scenarios. Verify inductance requirements for your application before selection.

Q: What is the advantage of FN2070-3-06 over FN2060-3-06?

A: FN2070-3-06 provides dual voltage capability (110V and 250VAC) and inductance of 9.8mH, which more closely matches the original FN670-3-06 inductance specification of 12.2mH. This makes it suitable for applications requiring either voltage level.

Q: Why does FN2090-3-06 have higher inductance than the original part?

A: FN2090-3-06 is specified with 14mH inductance and includes CE certification in addition to other regulatory approvals. The inductance value is a design characteristic of this series and does not indicate superiority or inferiority, only a different filtering profile.

Q: Are all substitutes available in the same packaging as FN670-3-06?

A: FN670-3-06 packaging is listed as "-" (not specified). All three substitute parts are supplied in Tray packaging. Confirm packaging compatibility with your procurement and assembly processes.

Q: Do all substitutes meet the same regulatory requirements as FN670-3-06?

A: FN670-3-06 carries CSA, ENEC, and UR certifications. FN2060-3-06 and FN2090-3-06 add CE certification. FN2070-3-06 maintains CSA, ENEC, and UR certifications. All meet or exceed the original certification requirements.

Q: What is the inventory status for these substitutes?

A: FN2060-3-06 has 3220 pcs in stock, FN2070-3-06 has 1167 pcs in stock, and FN2090-3-06 has 1230 pcs in stock. All are classified as new original stock.
