Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN422-4-13 is determined by the following critical parameters:

• Voltage Rating: Substitute must be rated for 250VAC minimum
• Current Rating: Substitute must support the 4A operating current or higher
• Filter Type & Configuration: Must be single-phase, single-stage EMC/EMI line filter
• Mounting & Termination: Must feature chassis mount with quick-connect termination
• Frequency Range: Must support DC to 400Hz operating range or equivalent
• Regulatory Compliance: Must hold CSA, ENEC, or equivalent certifications

The PS02/A0620/63 meets these substitution criteria through equivalent voltage and current specifications, matching filter topology, identical mounting and termination methods, and overlapping regulatory approvals.

Parameter Comparison

Engineering Selection Recommendations

The PS02/A0620/63 qualifies as a functional equivalent for the FN422-4-13 based on the following engineering criteria:

Voltage & Current Compatibility: Both components are rated for 250VAC. The PS02/A0620/63 provides a 6A current rating, which exceeds the 4A requirement of the FN422-4-13, ensuring adequate capacity for the original application.

Frequency Range: The PS02/A0620/63 operates across 50 ~ 400Hz, which encompasses the primary operating range of the FN422-4-13 (DC ~ 400Hz). The DC capability of the original part is not replicated; however, this represents a practical trade-off for an active, currently manufactured alternative.

Regulatory Compliance: Both components hold CSA and ENEC certifications. The PS02/A0620/63 additionally carries UL and VDE approvals, providing expanded regulatory coverage suitable for international applications.

Product Status: The FN422-4-13 is designated "Not For New Designs," while the PS02/A0620/63 maintains "Active" status with current manufacturing and inventory availability, supporting long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the PS02/A0620/63 directly replace the FN422-4-13 in existing applications?

A: Yes, the PS02/A0620/63 is functionally equivalent for applications operating within the 50 ~ 400Hz frequency range at 250VAC and 4A or lower current levels. Both components share identical mounting type (chassis mount), termination style (quick connect), filter topology (single-phase, single-stage), and regulatory certifications (CSA, ENEC).

Q: What is the significance of the different inductance values (2mH vs. 700µH)?

A: Inductance affects filter performance characteristics. The FN422-4-13 specifies 2mH, while the PS02/A0620/63 provides 700µH. This difference may influence attenuation profiles at specific frequencies. Application-specific EMI/RFI performance requirements should be verified against manufacturer datasheets.

Q: Does the PS02/A0620/63 support DC operation like the FN422-4-13?

A: The PS02/A0620/63 is specified for 50 ~ 400Hz operation and does not explicitly include DC capability. Applications requiring DC filtering should confirm compatibility with the substitute part's frequency specifications.

Q: Are there packaging differences between these components?

A: The FN422-4-13 is supplied in Tray packaging, while the PS02/A0620/63 is supplied in Bulk packaging. Procurement and handling procedures may differ accordingly.

Q: What certifications does each component hold?

A: The FN422-4-13 holds CSA, ENEC, and UR certifications. The PS02/A0620/63 holds CSA, ENEC, UL, and VDE certifications. Both meet ROHS3 compliance and REACH unaffected status.
