Substitute Part Grouping Explanation

The FN5420-480-99-E0XXT is identified as the manufacturer-recommended substitute for the FN5040-410-99. Substitution eligibility is determined by the following parameters:

• Filter Type: Both components are three-phase (Delta) EMC/EMI line filters
• Configuration: Both utilize single-stage filtering architecture
• Mounting Type: Both employ chassis mount configuration
• Termination Style: Both use terminal block termination
• Application: Both are rated for regenerative motor drive applications
• Current Capacity: The substitute (477 A) exceeds the original specification (410 A), providing operational headroom
• Inductance: The substitute (92µH) differs from the original (130µH), reflecting design optimization in the newer series
• Operating Temperature: The substitute (-40°C ~ 70°C) extends the lower temperature range compared to the original (-25°C ~ 70°C)
• Approval Agencies: The substitute carries expanded certifications (CE, cURus, UKCA) versus the original (cURus only)

Parameter Comparison

Engineering Selection Recommendations

The FN5420-480-99-E0XXT is the manufacturer-recommended substitute for the obsolete FN5040-410-99. Selection of the substitute is supported by the following factors:

• Product Status Alignment: The substitute is active and currently manufactured, ensuring long-term availability and supply chain continuity
• Functional Equivalence: Both components share identical filter type, configuration, mounting, and termination characteristics required for regenerative motor drive applications
• Current Capacity: The substitute's 477 A rating accommodates the original 410 A requirement with margin
• Expanded Certifications: The substitute carries CE, cURus, and UKCA approvals, providing broader regulatory compliance compared to the original cURus-only certification
• Extended Temperature Range: The substitute operates from -40°C, extending the lower operating boundary relative to the original -25°C specification

Frequently Asked Questions (FAQ)

Q: Can the FN5420-480-99-E0XXT directly replace the FN5040-410-99 in existing installations?

A: Yes. Both components share the same filter type (three-phase Delta), configuration (single stage), mounting method (chassis mount), and termination style (terminal block). The substitute's higher current rating (477 A versus 410 A) and expanded temperature range (-40°C versus -25°C) are compatible with the original application requirements.

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

A: The FN5040-410-99 has 130µH inductance while the FN5420-480-99-E0XXT has 92µH. This difference reflects design optimization in the newer FN 5420 series. Both values are appropriate for their respective current ratings and filtering performance in regenerative motor drive applications.

Q: Why does the substitute have voltage ratings specified while the original does not?

A: The FN5420-480-99-E0XXT includes explicit voltage specifications (480 V phase-to-ground/neutral, 530 V phase-to-phase) and frequency range (DC ~ 60Hz). These parameters define the operating envelope for the substitute. The original FN5040-410-99 datasheet does not provide these specifications in the available documentation.

Q: Are there packaging differences between these components?

A: The FN5040-410-99 is packaged as standard, while the FN5420-480-99-E0XXT is supplied in bulk packaging. Both use terminal block termination suitable for industrial chassis mount applications.

Q: What certifications apply to each component?

A: The FN5040-410-99 carries cURus approval. The FN5420-480-99-E0XXT carries CE, cURus, and UKCA approvals, providing compliance for broader geographic and regulatory requirements.
