F1250BB06 Equivalent & Substitute Parts

Part Overview

The F1250BB06 is a single-phase EMC/EMI line filter rated for 250VAC at 6A, designed for general-purpose chassis mount applications with wire lead termination. This active product operates at 50/60Hz and is ROHS3 compliant. Substitute parts may be required due to inventory constraints, application-specific certifications, or design revisions while maintaining equivalent filtering performance within specified electrical parameters.

Key Parameters

Substitute Part Grouping Explanation

The 5EK3 qualifies as a substitute based on the following matching parameters: single-phase filter type, single-stage configuration, 250V AC rating, 50/60Hz operating frequency, chassis mount design, and wire lead termination. Both parts maintain ROHS3 compliance and are active products suitable for general-purpose applications.

The primary distinction is current rating: the F1250BB06 is rated at 6A while the 5EK3 is rated at 5A. This difference requires application-level verification to ensure the substitute does not exceed its current specification in the target circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the F1250BB06 and 5EK3 are active products with ROHS3 compliance suitable for general-purpose single-phase filtering applications. The 5EK3 provides additional certifications (CSA, UR, VDE) and specified operating temperature range (-10°C ~ 40°C), which may be advantageous for regulated or temperature-sensitive environments.

Selection between these parts must account for the current rating difference: applications drawing 5A or less can use either part; applications requiring 6A operation must use the F1250BB06 to remain within rated specifications.

Frequently Asked Questions (FAQ)

Q: Can the 5EK3 replace the F1250BB06 in all applications? A: The 5EK3 is suitable only for applications where circuit current does not exceed 5A. The F1250BB06's 6A rating accommodates higher current loads. Verify actual circuit current before substitution.

Q: What is the significance of the inductance value listed for the 5EK3? A: The 516µH inductance specification for the 5EK3 defines its filtering characteristics. This parameter is not provided for the F1250BB06 in available documentation. Both parts function as single-stage filters at the specified voltage and frequency.

Q: Are there differences in packaging between these parts? A: The F1250BB06 is supplied in bulk packaging, while the 5EK3 is supplied in bag packaging. This affects handling and inventory management but does not impact electrical performance.

Q: Which part should be selected for new designs? A: Both parts are active products. Selection depends on application current requirements, required certifications, and operating temperature constraints. The 5EK3 offers broader certification coverage (CSA, UR, VDE) if regulatory compliance is a design requirement.
