Substitute Part Grouping Explanation

Substitution eligibility for the FN660-6-06 is determined by the following critical parameters:

Voltage Rating (AC): 250V minimum requirement
Current Rating: 6A
Filter Type: Single Phase
Configuration: Two Stage
Mounting Type: Chassis Mount
Termination Style: Quick Connect
Frequency Range: DC ~ 400Hz minimum
Approval Agencies: CSA, ENEC, UR certifications

The FN2060-6-06 and FN2090-6-06 meet these core electrical and mechanical requirements. Both are active products from the same manufacturer with identical current ratings, mounting configurations, and termination styles. The FN2090-6-06 provides additional voltage flexibility with dual 110V/250VAC rating capability.

Engineering Selection Recommendations

FN2060-6-06: This substitute maintains identical electrical specifications to the FN660-6-06 with matching voltage, current, and frequency ratings. It is an active product with enhanced ROHS3 compliance and additional CE certification. The inductance increase from 750µH to 970µH provides improved filtering performance. This part is the direct functional replacement for applications requiring 250VAC operation.

FN2090-6-06: This substitute offers dual voltage capability (110V/250VAC) while maintaining all other core specifications. It is an active product with ROHS3 compliance and CE certification. The significantly higher inductance of 8mH delivers enhanced EMI/EMC filtering. This part is suitable for applications requiring voltage flexibility or where higher filtering attenuation is beneficial. The operating temperature minimum is -20°C versus -25°C for the original part.

Both substitute parts are manufactured by Schaffner EMC Inc. and carry current product status with full regulatory certifications, making them suitable for new designs and legacy system replacements.

Frequently Asked Questions (FAQ)

Q: Can FN2060-6-06 be used as a direct replacement for FN660-6-06?

A: Yes. The FN2060-6-06 maintains identical voltage (250VAC), current (6A), mounting type (chassis mount), and termination style (quick connect) specifications. Both operate across DC to 400Hz frequency range with two-stage configuration. The FN2060-6-06 is an active product with enhanced compliance certifications.

Q: What is the difference between FN2060-6-06 and FN2090-6-06?

A: The primary difference is voltage rating. The FN2060-6-06 is rated for 250VAC only, while the FN2090-6-06 supports both 110VAC and 250VAC operation. The FN2090-6-06 also has significantly higher inductance (8mH versus 970µH), providing greater EMI filtering attenuation. Both share identical current, mounting, and termination specifications.

Q: Are there packaging differences between these parts?

A: The FN660-6-06 uses standard packaging, while both FN2060-6-06 and FN2090-6-06 are supplied in trays. Packaging does not affect electrical or mechanical compatibility for chassis-mount applications.

Q: Which substitute should be selected for a 110VAC application?

A: Only the FN2090-6-06 is rated for 110VAC operation. The FN2060-6-06 is rated for 250VAC only and is not suitable for 110VAC applications.

Q: Do the substitute parts have the same operating temperature range?

A: The FN2060-6-06 matches the original FN660-6-06 operating range of -25°C to 100°C. The FN2090-6-06 has a minimum operating temperature of -20°C (versus -25°C), with the same maximum of 100°C. This difference is not significant for most general-purpose applications.

Q: Are all three parts RoHS compliant?

A: Yes. The FN660-6-06 is RoHS Compliant. Both FN2060-6-06 and FN2090-6-06 are ROHS3 Compliant, representing enhanced compliance standards.
