Key Parameters

Substitute Part Grouping Explanation

Substitution for the FN685-10-06 is determined by the following critical parameters:

• Filter Type & Configuration: Single Phase, Two Stage
• Current Rating: 10 A
• Voltage Compatibility: 250VAC operation capability
• Frequency Range: DC ~ 400Hz
• Mounting & Termination: Chassis Mount with Quick Connect
• Regulatory Compliance: CSA, ENEC, UR certifications

The FN2090-10-06 and FN2080-10-06 are classified as direct and similar substitutes respectively. Both maintain the core electrical specifications (10A, two-stage single-phase configuration, quick-connect termination) and operate within the required frequency range. Both parts are active products with enhanced voltage flexibility (110V/250VAC) and current inventory availability.

Parameter Comparison

Engineering Selection Recommendations

FN2090-10-06 is the direct substitute for FN685-10-06. This part maintains all core electrical specifications while offering extended voltage range (110V/250VAC) and is currently in active production with robust inventory (1425 pcs). The FN2090-10-06 carries enhanced regulatory approval including CE certification and meets ROHS3 compliance. The inductance increase to 8mH represents improved filtering characteristics within the two-stage configuration.

FN2080-10-06 is a similar substitute with equivalent performance characteristics. This part matches the original inductance specification (4.5mH vs. 4.2mH) more closely and maintains the identical operating temperature range (-25°C ~ 100°C). The FN2080-10-06 is also in active production with strong inventory availability (1332 pcs) and carries ROHS3 compliance with CSA, ENEC, and UR certifications.

Both substitute parts are suitable for direct replacement in applications requiring 250VAC operation. Selection between FN2090-10-06 and FN2080-10-06 should be based on specific inductance requirements and voltage flexibility needs for the target application.

Frequently Asked Questions (FAQ)

Q: Can FN2090-10-06 and FN2080-10-06 be used interchangeably with FN685-10-06?

A: Both parts are suitable substitutes for the obsolete FN685-10-06 in applications requiring 250VAC, 10A single-phase filtering. Both maintain the two-stage configuration, quick-connect termination, and chassis-mount form factor. The primary difference is inductance specification (8mH for FN2090-10-06 vs. 4.5mH for FN2080-10-06 vs. 4.2mH for FN685-10-06).

Q: What is the difference between FN2090-10-06 and FN2080-10-06?

A: Both parts share identical core specifications for 10A, two-stage single-phase filtering at 250VAC. The FN2090-10-06 features higher inductance (8mH) and broader voltage compatibility (110V/250VAC). The FN2080-10-06 provides inductance closer to the original specification (4.5mH) and identical operating temperature range. Both are active products with current inventory.

Q: Are there packaging differences between these substitute parts?

A: Both FN2090-10-06 and FN2080-10-06 are supplied in Tray packaging, compared to the original FN685-10-06 specification. Packaging format should be verified against procurement requirements for the target application.

Q: Do the substitute parts meet the same regulatory certifications?

A: FN2080-10-06 maintains the original certification set (CSA, ENEC, UR). FN2090-10-06 extends certifications to include CE marking. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: What is the operating temperature range for each part?

A: FN685-10-06 and FN2080-10-06 operate across -25°C to 100°C. FN2090-10-06 operates across -20°C to 100°C, representing a 5°C reduction in minimum operating temperature. This difference should be evaluated for applications requiring extended low-temperature operation.
