Substitute Part Grouping Explanation

Substitution of the FN5045-115-35 is based on the following critical parameters:

• Filter Type: Three Phase (Delta) configuration must be maintained
• Configuration: Single Stage filtering architecture
• Mounting Type: Chassis Mount form factor
• Termination Style: Terminal Block connection method
• Application: Regenerative Motor Drive compatibility
• Current Rating: Minimum 115 A capacity required
• Approval Certifications: Compliance with industrial safety standards

The FN5420-145-99-E0XXT qualifies as a substitute based on matching filter type, configuration, mounting, termination, and application requirements while providing enhanced current capacity (145 A) and expanded operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The FN5420-145-99-E0XXT is the manufacturer-recommended substitute for the obsolete FN5045-115-35. Both components are manufactured by Schaffner EMC Inc. and share identical filter topology, mounting configuration, and termination methodology.

The FN5420-145-99-E0XXT provides active product status with expanded certifications (CE, cURus, UKCA) compared to the cURus-only certification of the original part. The substitute offers increased current capacity (145 A versus 115 A), extended low-temperature operating range (-40°C versus -25°C), and specified frequency operating range (DC ~ 60Hz).

The inductance value differs between the two parts (304µH versus 500µH), reflecting design optimization in the newer FN 5420 series. This parameter change is within the scope of equivalent substitution for three-phase delta EMC/EMI line filter applications.

Frequently Asked Questions (FAQ)

Q: Can the FN5420-145-99-E0XXT directly replace the FN5045-115-35 in existing installations?

A: Yes. Both components share identical filter type (three-phase delta), configuration (single stage), mounting type (chassis mount), and termination style (terminal block). The substitute maintains compatibility with regenerative motor drive applications and terminal block connection interfaces.

Q: What is the significance of the current rating difference (115 A versus 145 A)?

A: The FN5420-145-99-E0XXT has a higher current rating, making it suitable for applications requiring up to 145 A. It can be used in circuits designed for the original 115 A component without derating concerns.

Q: How does the inductance difference (500µH versus 304µH) affect substitution?

A: Inductance is a design parameter specific to each filter model. The FN 5420 series incorporates optimized inductance values for its operating specifications. Both values are appropriate for their respective filter designs in three-phase delta EMC/EMI applications.

Q: Why does the FN5420-145-99-E0XXT have additional certifications?

A: The FN5420-145-99-E0XXT includes CE and UKCA certifications in addition to cURus, reflecting broader regulatory compliance for international markets. These additional certifications do not affect substitution compatibility.

Q: Is the extended operating temperature range (-40°C versus -25°C) a consideration for substitution?

A: The FN5420-145-99-E0XXT supports a wider low-temperature operating range. If the original application operates within -25°C to 70°C, the substitute remains fully compatible. The extended range provides additional operational flexibility.

Q: What packaging format is available for the FN5420-145-99-E0XXT?

A: The FN5420-145-99-E0XXT is supplied in bulk packaging, consistent with industrial component distribution for chassis-mount filter applications.
