F1399AA20 Equivalent & Substitute Parts

Part Overview

The F1399AA20 is a single-phase EMC/EMI line filter rated for 250VAC at 20A, designed for chassis mount applications with quick connect termination. Manufactured by Curtis Industries, this filter operates at 50/60Hz and is ROHS3 compliant with active product status. Alternative equivalent parts may be required due to supply constraints, regional availability, or specific application requirements such as extended operating temperature ranges or alternative frequency specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the F1399AA20 is determined by strict equivalence across core electrical and mechanical parameters. All substitute parts must maintain the following specifications:

• Single-phase filter configuration with two-stage design
• 250V AC rated voltage
• 20A current rating
• Chassis mount installation method
• Quick connect termination interface
• ROHS3 compliance status
• Active product status

The identified substitute parts (1-6609031-7 and FN2060-20-06) meet these core requirements. Variations in operating temperature range, frequency bandwidth, inductance values, and approval agencies do not disqualify substitution but represent design differences that may affect suitability for specific applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and ROHS3 compliance, qualifying them as direct electrical and mechanical equivalents for 250VAC 20A single-phase EMC/EMI filtering applications.

The 1-6609031-7 (TE Connectivity Corcom) provides equivalent performance within a standard industrial operating temperature range (-10°C ~ 40°C) and carries CSA, UR, and VDE certifications. This part is suitable for general-purpose applications where operating conditions remain within specified limits.

The FN2060-20-06 (Schaffner EMC) extends operational capability to -25°C ~ 100°C and supports DC to 400Hz frequency operation, providing broader environmental tolerance. This part carries CE, CSA, ENEC, and UR certifications. The lower inductance value (600µH versus 880µH) may result in different filtering characteristics at specific frequency ranges.

Selection between substitutes should be based on application-specific requirements for operating temperature range, frequency bandwidth, and required regulatory certifications.

Frequently Asked Questions (FAQ)

Q: Can the 1-6609031-7 directly replace the F1399AA20?

A: Yes. Both parts share identical electrical ratings (250VAC, 20A, 50/60Hz), configuration (two-stage single-phase), and mechanical interface (chassis mount, quick connect). The 1-6609031-7 is electrically and mechanically equivalent for standard industrial applications.

Q: What is the primary difference between the FN2060-20-06 and the F1399AA20?

A: The FN2060-20-06 extends operating frequency to DC ~ 400Hz (versus 50/60Hz) and supports a wider temperature range (-25°C ~ 100°C). Inductance differs at 600µH compared to the unspecified value in the F1399AA20. These differences do not affect substitution for standard 50/60Hz applications but provide additional capability for specialized use cases.

Q: Are packaging differences significant for substitution?

A: Packaging format (Box, Bulk, or Tray) affects logistics and inventory management but does not impact electrical or mechanical compatibility. The quick connect termination and chassis mount interface remain consistent across all three parts.

Q: Which certifications are most critical for my application?

A: All three parts carry CSA and UR certifications. The F1399AA20 and FN2060-20-06 include CE certification. If your application requires specific regional compliance (such as ENEC for European markets or TUV), verify that the selected substitute carries the required certification.

Q: Does inductance variation affect filter performance?

A: Inductance values (880µH for 1-6609031-7 and 600µH for FN2060-20-06) influence attenuation characteristics at specific frequency ranges. For 50/60Hz applications, both values are acceptable. Applications requiring precise filtering at particular frequencies should evaluate inductance specifications against system requirements.
