FN680-2.5-06 Equivalent & Substitute Parts

Part Overview

The FN680-2.5-06 is a single-phase EMC/EMI line filter manufactured by Schaffner EMC Inc., rated for 250VAC at 2.5A 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 product is currently obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new designs requiring compatible filtering solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN680-2.5-06 is determined by the following critical parameters:

• Filter Type: Single Phase (required match)
• Configuration: Two Stage (required match)
• Mounting Type: Chassis Mount (required match)
• Termination Style: Quick Connect (required match)
• Frequency Range: DC ~ 400Hz (required match)
• Voltage Compatibility: Substitute must support 250VAC operation
• Current Rating: Substitute must equal or exceed 2.5A
• Inductance: Substitute inductance must be compatible with circuit requirements

The FN2080-3-06 and FN2090-3-06 meet all structural and operational requirements. Both are single-phase, two-stage, chassis-mount filters with quick connect termination, operating across DC to 400Hz. Both support 250VAC operation and exceed the 2.5A current requirement at 3A rating. These parts maintain functional equivalence while offering active product status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both FN2080-3-06 and FN2090-3-06 are suitable replacements for the obsolete FN680-2.5-06 based on functional equivalence and compliance status.

FN2080-3-06 offers active product status with CSA, ENEC, and UR certifications, supporting dual voltage operation (110V/250VAC) at 3A with 9.8mH inductance and an extended operating temperature range of -25°C to 100°C.

FN2090-3-06 provides active product status with the broadest certification scope including CE, CSA, ENEC, and UR approvals, supporting dual voltage operation (110V/250VAC) at 3A with 14mH inductance and an operating temperature range of -20°C to 100°C. The inductance value of 14mH is closer to the original FN680-2.5-06 specification of 16mH.

Selection between these two substitutes should be based on specific certification requirements for the target application and inductance compatibility with existing circuit design parameters.

Frequently Asked Questions (FAQ)

Q: Can FN2080-3-06 or FN2090-3-06 directly replace FN680-2.5-06 in existing designs?

A: Yes, both substitute parts maintain functional equivalence across all critical parameters: single-phase, two-stage configuration, chassis mount, quick connect termination, DC to 400Hz operation, and 250VAC support. The higher current rating (3A vs. 2.5A) provides additional capacity margin.

Q: What is the significance of the inductance difference between FN680-2.5-06 (16mH) and the substitutes?

A: Inductance affects filter performance characteristics. FN2090-3-06 at 14mH is closer to the original specification than FN2080-3-06 at 9.8mH. Circuit-specific requirements should determine which inductance value is appropriate for your application.

Q: Are there packaging differences between these parts?

A: FN680-2.5-06 packaging is not specified in available data. FN2080-3-06 and FN2090-3-06 are supplied in Tray packaging.

Q: Which substitute offers broader regulatory compliance?

A: FN2090-3-06 includes CE certification in addition to CSA, ENEC, and UR approvals, providing the broadest compliance scope for international applications.

Q: Do the substitute parts support the same voltage range as the original?

A: Both substitutes support 250VAC operation required by FN680-2.5-06. Additionally, both support 110VAC operation, providing expanded voltage flexibility not present in the original part.

Q: What is the inventory status of these substitute parts?

A: FN2080-3-06 has 1342 pieces in stock and FN2090-3-06 has 1230 pieces in stock, both listed as new original inventory.
