FN420-6.5-13 Equivalent & Substitute Parts

Part Overview

The FN420-6.5-13 is a single-phase EMC/EMI line filter manufactured by Schaffner EMC Inc., rated for 250VAC at 6.5A with DC to 400Hz operating frequency range. This chassis-mount filter features quick-connect termination and is designed for general-purpose applications requiring electromagnetic compatibility filtering.

The FN420-6.5-13 carries a "Not For New Designs" product status, making identification of functionally equivalent alternatives necessary for ongoing procurement and new system development. Substitute parts must maintain compatibility across voltage rating, current capacity, mounting configuration, and termination style while meeting applicable regulatory compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN420-6.5-13 is determined by the following critical parameters:

• Voltage rating must be 250VAC or higher
• Current capacity must meet or exceed 6.5A
• Filter type must be single-phase
• Configuration must be single-stage
• Mounting type must be chassis mount
• Termination style must be quick connect
• Operating frequency range must encompass the application requirements
• Regulatory approvals must satisfy system compliance requirements

The PS02/A1020/63 qualifies as a substitute based on these criteria. While the substitute exhibits different inductance (350µH versus 750µH) and an extended operating temperature range, these variations remain within acceptable parameters for equivalent functional performance in general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

The PS02/A1020/63 is suitable as a substitute for the FN420-6.5-13 in applications where the following conditions are met:

The substitute provides higher current capacity (10A versus 6.5A), ensuring adequate margin for the original application. Both parts maintain 250VAC voltage compatibility and single-phase, single-stage configuration with chassis-mount quick-connect termination.

The PS02/A1020/63 carries Active product status, providing long-term availability and supply chain stability compared to the FN420-6.5-13's "Not For New Designs" designation. Both parts achieve ROHS3 compliance and REACH unaffected status.

Regulatory approvals differ slightly: the substitute adds UL and VDE certifications while maintaining CSA and ENEC coverage. The operating frequency range of the substitute (50 ~ 400Hz) covers the primary industrial frequency band, though it does not extend to DC operation as the original part does. Applications requiring DC operation must verify compatibility with the 50Hz minimum frequency specification of the substitute.

Frequently Asked Questions (FAQ)

Q: Can the PS02/A1020/63 directly replace the FN420-6.5-13 in existing designs?

A: Yes, provided the application does not require DC operation. The substitute meets or exceeds all critical electrical parameters: voltage rating, current capacity, filter type, configuration, mounting type, and termination style. Physical form factor compatibility should be verified against the specific chassis installation requirements.

Q: What is the significance of the current rating difference (6.5A versus 10A)?

A: The higher current rating of the substitute provides additional capacity margin. For applications drawing 6.5A or less, the PS02/A1020/63 operates within its rated specification with headroom for transient conditions. No derating or performance degradation occurs.

Q: Does the inductance difference (750µH versus 350µH) affect substitutability?

A: Inductance values are provided as specified parameters. The lower inductance of the substitute may result in different filtering characteristics at specific frequencies. System-level EMI performance validation is the responsibility of the design engineer and must be conducted within the context of the complete application.

Q: Why does the substitute not support DC operation?

A: The PS02/A1020/63 specifies a 50Hz minimum operating frequency, whereas the FN420-6.5-13 operates from DC. Applications requiring DC filtering must retain the original part or identify alternatives with DC-rated specifications.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the FN420-6.5-13 and PS02/A1020/63 are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance regulations.

Q: What packaging differences exist between these parts?

A: The FN420-6.5-13 is supplied in Tray packaging, while the PS02/A1020/63 is supplied in Bulk packaging. Procurement and handling procedures may differ accordingly.
