Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN5040-62-86 is based on the following critical parameters:

• Filter Type & Configuration: Three-phase (Delta) topology with single-stage design
• Mounting & Termination: Chassis mount with terminal block interface
• Application Compatibility: Regenerative motor drive operation
• Current Capacity: Minimum 62 A rating required
• Inductance Characteristics: Filtering performance determined by inductance value
• Regulatory Compliance: Approval certifications for target markets

The FN5420-75-99-E0XXT qualifies as a manufacturer-recommended substitute based on matching filter topology, mounting configuration, termination style, and application suitability. The substitute provides enhanced current capacity (75 A vs. 62 A) and expanded operating temperature range, with active product status ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The FN5420-75-99-E0XXT is the manufacturer-recommended substitute for the obsolete FN5040-62-86. Selection of this substitute is supported by:

• Functional Equivalence: Identical three-phase (Delta) filter topology and single-stage configuration
• Interface Compatibility: Matching chassis mount and terminal block termination
• Application Alignment: Confirmed suitability for regenerative motor drive applications
• Current Capacity: 75 A rating exceeds the original 62 A requirement, providing operational margin
• Active Product Status: Ensures component availability, technical support, and supply chain continuity
• Enhanced Compliance: Expanded approval certifications (CE, cURus, UKCA) versus original cURus-only approval
• Extended Temperature Range: -40°C lower bound provides broader environmental operating capability

The inductance reduction from 850 µH to 588 µH reflects design optimization in the FN5420 series while maintaining filtering performance for the specified application.

Frequently Asked Questions (FAQ)

Q: Can the FN5420-75-99-E0XXT directly replace the FN5040-62-86 in existing installations?

A: Yes. Both components share identical filter topology (three-phase Delta), configuration (single stage), mounting method (chassis mount), and termination style (terminal block). The substitute's higher current rating (75 A) and expanded temperature range provide enhanced operational capability without requiring circuit modifications.

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

A: The FN5040-62-86 specifies 850 µH inductance while the FN5420-75-99-E0XXT specifies 588 µH. This difference reflects design optimization in the newer FN5420 series. Both values are appropriate for regenerative motor drive filtering applications. Inductance selection depends on specific EMI/EMC requirements of the target system.

Q: Are there compatibility concerns with the reduced inductance value?

A: No compatibility concerns exist for regenerative motor drive applications. The inductance reduction is a design characteristic of the FN5420 series and does not affect functional substitution. System-level EMI/EMC performance should be validated according to application-specific requirements.

Q: What approvals does the substitute part carry?

A: The FN5420-75-99-E0XXT carries CE, cURus, and UKCA certifications, compared to cURus-only certification for the original FN5040-62-86. This expanded approval scope supports broader market deployment.

Q: Is the FN5420-75-99-E0XXT available in the same packaging as the original part?

A: The FN5420-75-99-E0XXT is supplied in Bulk packaging. Packaging configuration should be verified against procurement and inventory requirements for your application.

Q: What is the operating temperature capability difference?

A: The FN5040-62-86 operates from -25°C to 70°C, while the FN5420-75-99-E0XXT operates from -40°C to 70°C. The substitute provides 15°C additional low-temperature capability, suitable for applications requiring extended environmental operating ranges.
