Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FN680-1-06 are qualified based on the following critical parameters that determine functional equivalence:

• Single-phase filter configuration
• Two-stage design
• 1A current rating
• DC to 400Hz operating frequency range
• Chassis mount with quick connect termination
• Voltage compatibility with 250VAC operation

The FN2080-1-06 and FN2090-1-06 both satisfy these core requirements. Both substitute parts support dual voltage operation (110V/250VAC), providing broader application flexibility while maintaining the 1A current rating, two-stage configuration, and quick connect interface. The inductance values (22mH for FN2080-1-06 and 20mH for FN2090-1-06) remain within acceptable tolerance of the original 22.5mH specification for general-purpose filtering applications.

Parameter Comparison

Engineering Selection Recommendations

Both FN2080-1-06 and FN2090-1-06 are active products suitable for replacing the obsolete FN680-1-06. Selection between these two substitutes should be based on regulatory compliance requirements for the target application:

The FN2080-1-06 carries CSA, ENEC, and UR certifications with an operating temperature range of -25°C to 100°C.

The FN2090-1-06 carries CE, CSA, ENEC, and UR certifications with an operating temperature range of -20°C to 100°C, providing broader international regulatory coverage including CE marking for European markets.

Both parts maintain RoHS3 compliance and REACH unaffected status. The inductance specifications (22mH and 20mH respectively) are within acceptable tolerance for general-purpose EMC/EMI filtering applications requiring the original 22.5mH specification.

Frequently Asked Questions (FAQ)

Q: Can FN2080-1-06 or FN2090-1-06 directly replace FN680-1-06 in existing designs?

A: Both substitute parts maintain identical current rating (1A), voltage compatibility at 250VAC, two-stage configuration, chassis mount design, and quick connect termination. The inductance values are within tolerance for general-purpose applications. Physical form factor compatibility must be verified against the original installation specifications.

Q: What is the difference between FN2080-1-06 and FN2090-1-06?

A: Both parts share the same electrical specifications (1A, 250VAC, two-stage, DC-400Hz). The primary differences are inductance (22mH vs 20mH), operating temperature range (-25°C to 100°C vs -20°C to 100°C), and regulatory certifications. FN2090-1-06 includes CE marking for European compliance.

Q: Why do the substitute parts support dual voltage (110V/250VAC) while the original supports only 250VAC?

A: The dual voltage capability of FN2080-1-06 and FN2090-1-06 provides enhanced application flexibility. When operated at 250VAC, these parts are fully compatible with the original FN680-1-06 specification.

Q: Are there packaging differences between these parts?

A: FN680-1-06 packaging is listed as standard, while both FN2080-1-06 and FN2090-1-06 are supplied in tray packaging. Tray packaging is standard for active production parts and does not affect electrical performance or installation compatibility.

Q: Which substitute should be selected for new designs?

A: FN2090-1-06 is recommended for new designs requiring international regulatory coverage, as it includes CE certification in addition to CSA, ENEC, and UR approvals. For applications limited to North American markets, FN2080-1-06 provides equivalent electrical performance with CSA and UR certifications.
