FN670-1.8-06 Equivalent & Substitute Parts

Part Overview

The FN670-1.8-06 is a single-phase EMC/EMI line filter manufactured by Schaffner EMC Inc., rated for 250VAC at 1.8A with two-stage configuration and quick connect termination. This component is classified as obsolete product status. Due to its obsolete classification, equivalent substitute parts from the active FN series product line are available to maintain system compatibility and ensure continued supply chain access for applications requiring single-phase EMC filtration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN670-1.8-06 is determined by the following critical parameters:

• Filter Type: Single Phase (all substitutes maintain this requirement)
• Configuration: Two Stage (all substitutes maintain this requirement)
• Mounting Type: Chassis Mount (all substitutes maintain this requirement)
• Termination Style: Quick Connect (all substitutes maintain this requirement)
• Frequency Range: DC ~ 400Hz (all substitutes maintain this requirement)
• Voltage Compatibility: 250VAC operation (all substitutes support 250VAC)
• Current Rating: Substitutes must equal or exceed 1.8A requirement

Three substitute parts meet these criteria: FN2090-1-06, FN2070-3-06, and FN2060-3-06. All are active products from Schaffner EMC Inc. with identical mechanical and electrical configuration parameters.

Parameter Comparison

Engineering Selection Recommendations

FN2090-1-06: This substitute operates at 1A current rating, which is below the 1.8A requirement of the FN670-1.8-06. This part is suitable only for applications where the actual operating current does not exceed 1A. The FN2090-1-06 provides dual voltage support (110V/250V) and carries CE certification in addition to CSA, ENEC, and UR approvals. Product status is active with ROHS3 compliance.

FN2070-3-06: This substitute operates at 3A current rating, exceeding the 1.8A requirement. The FN2070-3-06 provides dual voltage support (110V/250V) and carries CSA, ENEC, and UR approvals. Product status is active with ROHS3 compliance. Operating temperature range is -25°C ~ 100°C.

FN2060-3-06: This substitute operates at 3A current rating, exceeding the 1.8A requirement. The FN2060-3-06 is rated for 250VAC only, matching the original voltage specification. This part carries CE certification in addition to CSA, ENEC, and UR approvals. Product status is active with ROHS3 compliance. Operating temperature range is -25°C ~ 100°C.

All three substitutes maintain identical mechanical configuration (chassis mount, quick connect termination) and electrical operating range (DC ~ 400Hz). Selection should be based on current capacity requirements and voltage range needs for the target application.

Frequently Asked Questions (FAQ)

Q: Can FN2090-1-06 directly replace FN670-1.8-06?

A: FN2090-1-06 has a 1A current rating, which is lower than the 1.8A rating of FN670-1.8-06. Direct replacement is only suitable for applications where actual operating current does not exceed 1A. For applications requiring the full 1.8A capacity, FN2070-3-06 or FN2060-3-06 are appropriate choices.

Q: What is the difference between FN2070-3-06 and FN2060-3-06?

A: Both parts are rated for 3A at 250VAC with two-stage configuration and quick connect termination. FN2070-3-06 supports dual voltage operation (110V/250V) with 9.8mH inductance, while FN2060-3-06 is rated for 250VAC only with 2.5mH inductance. FN2060-3-06 carries CE certification; FN2070-3-06 does not list CE certification.

Q: Are all substitutes RoHS compliant?

A: Yes. FN670-1.8-06 is RoHS Compliant. All three substitute parts (FN2090-1-06, FN2070-3-06, FN2060-3-06) are ROHS3 Compliant, meeting current RoHS requirements.

Q: What certifications does each substitute carry?

A: FN2090-1-06 carries CE, CSA, ENEC, and UR certifications. FN2070-3-06 carries CSA, ENEC, and UR certifications. FN2060-3-06 carries CE, CSA, ENEC, and UR certifications. The original FN670-1.8-06 carries CSA, ENEC, and UR certifications.

Q: Does inductance variation affect substitution suitability?

A: Inductance values differ among substitutes (FN2090-1-06: 20mH, FN2070-3-06: 9.8mH, FN2060-3-06: 2.5mH versus FN670-1.8-06: 7.2mH). Inductance is a provided parameter and must be evaluated based on specific application filtering requirements. All parts maintain the two-stage configuration and DC ~ 400Hz operating frequency.

Q: What is the packaging difference?

A: FN670-1.8-06 packaging is listed as dash (-). All three substitute parts are supplied in Tray packaging.
