Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FN660-1-06 are identified based on the following critical parameters that determine functional equivalence:

Core Matching Criteria:

• Filter Type: Single Phase
• Configuration: Two Stage
• Voltage - Rated AC: 250V (minimum requirement)
• Current: 1 A
• Frequency - Operating: DC ~ 400Hz
• Mounting Type: Chassis Mount
• Termination Style: Quick Connect
• Applications: General Purpose

The FN2060-1-06 and FN2090-1-06 both satisfy these core electrical and mechanical requirements. Both are active-status products from Schaffner EMC Inc., offering improved availability compared to the obsolete FN660-1-06. The FN2090-1-06 provides additional voltage flexibility with dual-voltage capability (110V/250VAC), while the FN2060-1-06 maintains single 250V operation.

Parameter Comparison

Engineering Selection Recommendations

FN2060-1-06 is the direct functional equivalent for applications requiring 250VAC operation. This part maintains identical voltage and current specifications with active product status and enhanced regulatory compliance (ROHS3). The increased inductance (12mH vs. 3mH) reflects modern filter design standards and provides improved EMI suppression characteristics. This part is recommended for direct replacement in 250VAC-only systems.

FN2090-1-06 provides extended voltage flexibility with dual-voltage capability (110V/250VAC) while maintaining all other core specifications. This part is suitable for applications requiring operation across multiple voltage standards or for designs with future voltage flexibility requirements. The higher inductance (20mH) offers enhanced filtering performance. This part is recommended for applications where dual-voltage operation is beneficial or anticipated.

Both substitute parts carry active product status, ensuring long-term availability and supply chain stability. Both meet current regulatory requirements with ROHS3 compliance and expanded approval agency certifications (CE added). Selection between FN2060-1-06 and FN2090-1-06 depends on whether single or dual-voltage operation is required for the application.

Frequently Asked Questions (FAQ)

Q: Can FN2060-1-06 or FN2090-1-06 directly replace FN660-1-06 in existing designs?

A: Both parts satisfy the core electrical and mechanical requirements: single-phase, two-stage configuration, 1A current rating, 250VAC operation, DC to 400Hz frequency range, chassis mount, and quick connect termination. Physical form factor compatibility must be verified through mechanical drawings, as packaging differences may affect installation.

Q: What is the significance of the inductance difference between these parts?

A: The FN660-1-06 specifies 3mH inductance, while FN2060-1-06 provides 12mH and FN2090-1-06 provides 20mH. Higher inductance values indicate enhanced EMI filtering performance. These differences reflect design evolution within the Schaffner product line. For applications with specific inductance requirements, the original specification must be confirmed.

Q: Why do FN2060-1-06 and FN2090-1-06 have higher inductance values?

A: Modern EMC filter designs incorporate higher inductance to achieve improved attenuation of electromagnetic interference across the operating frequency range. This represents an engineering advancement in filter technology rather than a limitation.

Q: Is the FN2090-1-06 suitable for 250VAC-only applications?

A: Yes. The FN2090-1-06 is rated for both 110V and 250VAC operation. It functions correctly at 250VAC and provides the additional capability for 110VAC operation if needed.

Q: What is the difference in operating temperature range?

A: The FN660-1-06 and FN2060-1-06 operate from -25°C to 100°C. The FN2090-1-06 operates from -20°C to 100°C. For applications requiring operation below -20°C, FN2060-1-06 is the appropriate choice.

Q: Are there packaging differences between these parts?

A: The FN660-1-06 packaging is listed as "-" (unspecified). Both FN2060-1-06 and FN2090-1-06 are supplied in Tray packaging. Packaging format may affect handling, storage, and installation procedures.

Q: What regulatory certifications apply to each part?

A: FN660-1-06 carries CSA, ENEC, and UR approvals. FN2060-1-06 and FN2090-1-06 carry CE, CSA, ENEC, and UR approvals. The addition of CE certification on the substitute parts reflects current European regulatory requirements.
