Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN420-1-13 is determined by strict alignment with the following parameters:

• Voltage Rating (AC): Must be rated for 250V
• Current Rating: Must be rated for 1 A minimum
• Filter Type: Must be single-phase configuration
• Configuration: Must be single-stage design
• Mounting Type: Must support chassis mount installation
• Termination Style: Must feature quick connect terminals
• RoHS Compliance: Must meet ROHS3 requirements

The PS02/A0120/63 from Bulgin satisfies all mandatory substitution criteria. While inductance values differ (10 mH vs. 13 mH), both components operate within the same functional class and meet identical voltage, current, and configuration requirements. The operating frequency range of the substitute (50 ~ 400Hz) encompasses the main part's range (DC ~ 400Hz), ensuring compatibility in standard industrial applications.

Parameter Comparison

Engineering Selection Recommendations

The PS02/A0120/63 qualifies as a direct functional equivalent for the FN420-1-13 based on matching electrical ratings and mechanical interface specifications. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The Bulgin substitute carries active product status, ensuring ongoing availability and manufacturer support. The PS02/A0120/63 holds additional regulatory approvals (UL, VDE) beyond those of the original part, providing expanded certification coverage for applications requiring broader geographic or industry-specific compliance.

The inductance differential (10 mH vs. 13 mH) represents a 23% reduction in the substitute design. This parameter variation falls within acceptable tolerances for general-purpose EMC/EMI filtering applications where the primary function is conducted emissions suppression across the specified frequency range.

Frequently Asked Questions (FAQ)

Q: Can the PS02/A0120/63 be used as a direct replacement for the FN420-1-13?

A: Yes. Both components share identical voltage ratings (250VAC), current ratings (1A), filter type (single-phase), configuration (single-stage), mounting method (chassis mount), and termination style (quick connect). These parameters define functional compatibility for EMC/EMI line filter applications.

Q: What is the significance of the inductance difference between the two filters?

A: The FN420-1-13 specifies 13 mH inductance while the PS02/A0120/63 specifies 10 mH. Both values operate within the single-stage filter classification and support the same voltage and current ratings. The inductance value influences the filter's attenuation characteristics across the frequency spectrum; however, both components are designed for general-purpose applications within the DC to 400Hz operating range.

Q: Are there any compliance or certification differences?

A: The FN420-1-13 holds CSA, ENEC, and UR approvals. The PS02/A0120/63 holds CSA, ENEC, UL, and VDE approvals. Both are ROHS3 compliant and REACH unaffected. The substitute provides additional UL and VDE certifications, which may be advantageous for specific regional or industry requirements.

Q: What is the product status implication of the FN420-1-13 being "Not For New Designs"?

A: This designation indicates the FN420-1-13 has been discontinued from the manufacturer's active product line. The PS02/A0120/63 carries "Active" status, confirming ongoing production, availability, and manufacturer technical support.

Q: Does the operating frequency range difference affect substitution suitability?

A: The FN420-1-13 operates from DC to 400Hz, while the PS02/A0120/63 operates from 50Hz to 400Hz. For applications requiring DC filtering capability, the frequency range difference must be evaluated against specific system requirements. For standard industrial AC applications within the 50-400Hz range, both components are functionally equivalent.

Q: Are there any mechanical or packaging considerations for installation?

A: Both components feature chassis mount configuration with quick connect termination. Physical dimensions and connector specifications are not provided in the available technical parameters. Mechanical fit verification is recommended during component procurement to confirm compatibility with existing mounting infrastructure.
