F1399AA02 Equivalent & Substitute Parts

Part Overview

The F1399AA02 is a single-phase EMC/EMI line filter manufactured by Curtis Industries, rated for 250VAC at 2A with 50/60Hz operation. This chassis-mount filter features a two-stage configuration with quick-connect termination, designed for general-purpose applications requiring electromagnetic compatibility filtering. The part is active in production with ROHS3 compliance and holds multiple international approvals including CE, CSA, TUV, and UR certifications. Substitute parts are identified when equivalent electrical specifications and mechanical mounting requirements are met across alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the F1399AA02 is determined by strict equivalence across the following critical parameters: rated AC voltage (250V), current rating (2A), operating frequency (50/60Hz), filter type (single phase), configuration (two stage), and mounting type (chassis mount). All identified substitutes maintain these core electrical and mechanical specifications. Termination style variations (quick connect versus wire leads) are permitted as secondary differentiators within the substitute group, as they do not affect the filtering function or electrical performance. RoHS3 compliance is maintained across all substitutes. Regulatory approvals may vary by manufacturer but remain within recognized international standards (CSA, UR, VDE).

Parameter Comparison

Engineering Selection Recommendations

All three parts meet the core electrical and mechanical requirements for single-phase EMC/EMI line filtering at 250VAC, 2A, 50/60Hz operation. The F1399AA02 and 6609031-3 are directly interchangeable, both featuring quick-connect termination. The 6609031-4 variant uses wire leads instead of quick-connect terminals, requiring circuit board layout or connector modifications during integration. Selection between Curtis Industries F1399AA02 and TE Connectivity 6609031 series should be based on supply chain availability, packaging requirements (box versus bulk), and termination compatibility with the target application. All parts maintain active production status and ROHS3 compliance. Regulatory certifications differ slightly: F1399AA02 includes CE, CSA, TUV, and UR approvals, while 6609031 series carries CSA, UR, and VDE certifications.

Frequently Asked Questions (FAQ)

Q: Can 6609031-3 directly replace F1399AA02 in an existing design? A: Yes. Both parts share identical electrical ratings (250VAC, 2A, 50/60Hz), single-phase two-stage configuration, chassis mounting, and quick-connect termination. No circuit modifications are required.

Q: What is the difference between 6609031-3 and 6609031-4? A: The primary difference is termination style. The 6609031-3 uses quick-connect terminals matching the F1399AA02, while 6609031-4 uses wire leads. Both maintain identical electrical specifications and filtering performance. Selection depends on circuit board connector compatibility.

Q: Are there packaging differences between these parts? A: Yes. The F1399AA02 is supplied in box packaging, while both TE Connectivity 6609031 variants are supplied in bulk packaging. This affects inventory management and handling but does not impact electrical or mechanical performance.

Q: Do all three parts have the same regulatory approvals? A: No. The F1399AA02 carries CE, CSA, TUV, and UR certifications. The 6609031 series carries CSA, UR, and VDE certifications. Both meet recognized international standards for EMC/EMI filtering. Verify specific approval requirements for your target market before selection.

Q: Is the inductance specification relevant for substitution? A: The inductance value (1.078mH for 6609031 series) is provided for the substitute parts but not specified for the F1399AA02 in the available data. Both parts function as two-stage filters at the specified electrical ratings. Inductance differences do not affect substitution eligibility based on the provided parameters.
