Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN5045-410-99 is determined by the following critical parameters:

• Filter Type & Configuration: Three-phase (Delta) topology with single-stage design
• Mounting & Termination: Chassis mount with terminal block interface
• Current Capacity: Minimum 410 A rating required for direct substitution
• Application Compatibility: Regenerative motor drive operation
• Regulatory Compliance: Certifications meeting or exceeding original approvals

The FN5420-480-99-E0XXT qualifies as a manufacturer-recommended substitute based on matching filter topology, mounting configuration, termination style, and application suitability. The substitute provides higher current capacity (477 A) and expanded voltage ratings, supporting broader system integration scenarios.

Engineering Selection Recommendations

The FN5420-480-99-E0XXT is the manufacturer-recommended substitute for the obsolete FN5045-410-99. Selection of this substitute is supported by:

• Active Product Status: The substitute maintains current manufacturing and support status, ensuring long-term availability and supply chain continuity.
• Enhanced Regulatory Coverage: The substitute carries CE, cURus, and UKCA certifications, exceeding the original cURus-only approval and providing broader market compliance.
• Increased Current Capacity: The 477 A rating accommodates the original 410 A requirement with operational margin.
• Extended Temperature Range: Operating range of -40°C ~ 70°C provides wider environmental tolerance compared to the original -25°C ~ 70°C specification.
• Specified Frequency & Voltage Parameters: The substitute includes explicit DC ~ 60 Hz frequency rating and defined voltage specifications (480 V phase-to-ground, 530 V phase-to-phase), enabling precise system integration.

Frequently Asked Questions (FAQ)

Q: Can the FN5420-480-99-E0XXT directly replace the FN5045-410-99 in existing installations?

A: Yes. Both components share identical filter topology (three-phase Delta), configuration (single stage), mounting type (chassis mount), and termination style (terminal block). The substitute's higher current rating (477 A vs. 410 A) and expanded certifications ensure compatibility with the original application.

Q: What is the difference in inductance between these parts?

A: The FN5045-410-99 has 130 µH inductance, while the FN5420-480-99-E0XXT has 92 µH. This difference reflects design optimization in the newer model and does not prevent substitution for regenerative motor drive applications.

Q: Does the substitute support the same frequency range as the original?

A: The original part does not specify frequency range. The substitute is rated for DC ~ 60 Hz operation, providing explicit frequency compatibility for regenerative motor drive systems.

Q: Are there packaging differences between these parts?

A: The FN5045-410-99 is packaged as standard, while the FN5420-480-99-E0XXT is supplied in bulk packaging. Both maintain identical mechanical form factor and terminal block interface.

Q: What certifications does the substitute carry?

A: The FN5420-480-99-E0XXT carries CE, cURus, and UKCA certifications, compared to cURus-only for the original part. This expanded certification scope supports broader regulatory compliance requirements.
