Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN682-6.5-06 is determined by the following critical parameters:

• Single-phase filter configuration with two-stage topology
• Quick connect termination style for chassis mounting
• Operating frequency range DC ~ 400Hz
• Voltage compatibility at 250VAC
• Current rating equal to or greater than 6.5A
• Inductance characteristics within acceptable range for EMC/EMI filtering

The substitute parts FN2090-6-06 and FN2080-10-06 maintain compatibility across these core parameters while offering active product status and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

FN2090-6-06 provides the closest current rating match at 6A, with dual voltage capability (110V/250V) and active product status. This part carries expanded regulatory approvals including CE and ENEC certifications, and meets ROHS3 compliance. The higher inductance value (8mH) provides enhanced filtering characteristics compared to the original specification.

FN2080-10-06 offers higher current capacity at 10A with dual voltage rating and active product status. This part is suitable for applications requiring current headroom beyond the original 6.5A specification. ROHS3 compliance and ENEC certification provide modern regulatory alignment. The inductance value (4.5mH) remains closely aligned with the original design.

Both substitute parts maintain the essential two-stage single-phase configuration, quick connect termination, chassis mount design, and DC ~ 400Hz operating frequency range required for functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can FN2090-6-06 directly replace FN682-6.5-06?

A: FN2090-6-06 is functionally equivalent for 250VAC applications at or below 6A current draw. The part maintains identical filter topology, termination style, mounting configuration, and operating frequency range. The higher inductance (8mH vs 4.1mH) provides improved EMC/EMI filtering performance.

Q: When should FN2080-10-06 be selected instead of FN2090-6-06?

A: FN2080-10-06 is appropriate when the application requires current capacity exceeding 6A. The 10A rating provides margin for systems operating at 6.5A or higher. Both parts are electrically compatible at 250VAC with identical filter configuration and termination.

Q: Are there voltage compatibility differences between substitutes?

A: FN2090-6-06 and FN2080-10-06 both support dual voltage operation at 110V and 250VAC. The original FN682-6.5-06 is rated for 250VAC only. Substitutes may be used in 250VAC applications without restriction.

Q: What is the impact of inductance differences?

A: Inductance values (4.1mH original, 4.5mH for FN2080-10-06, 8mH for FN2090-6-06) affect filtering attenuation characteristics. Higher inductance provides greater high-frequency noise suppression. All values remain within acceptable range for two-stage EMC/EMI filter topology.

Q: Do packaging differences affect compatibility?

A: FN682-6.5-06 uses standard packaging while FN2090-6-06 and FN2080-10-06 are supplied in tray packaging. Packaging does not affect electrical or mechanical compatibility for chassis-mount applications.

Q: What regulatory advantages do the substitute parts offer?

A: Both FN2090-6-06 and FN2080-10-06 carry ROHS3 compliance versus RoHS compliance for the original part. FN2090-6-06 includes CE and ENEC certifications in addition to CSA and UR approvals. FN2080-10-06 includes ENEC certification. These certifications support compliance with current international standards.
