FN5045-8-44 Equivalent & Substitute Parts

Part Overview

The FN5045-8-44 is a three-phase (delta) EMC/EMI line filter rated for 8 A AC, designed for chassis mount applications with terminal block termination. This component is classified as obsolete, making identification of equivalent and substitute parts essential for system redesign, maintenance, and procurement planning. The filter is specifically engineered for regenerative motor drive applications requiring single-stage EMI suppression in three-phase delta configurations.

Substitute Part Grouping Explanation

Substitute parts for the FN5045-8-44 must satisfy the following critical parameters to ensure functional equivalence:

• Filter Type: Three-phase (delta) configuration
• Current Rating: 8 A AC minimum
• Mounting Type: Chassis mount
• Termination Style: Terminal block
• Configuration: Single-stage EMI/EMC filtering
• Application Compatibility: Regenerative motor drive systems
• Regulatory Compliance: cURus approval or equivalent recognized certification
• Environmental Compliance: ROHS3 compliant and REACH unaffected status

No manufacturer-recommended substitute parts have been provided for this component. Selection of alternative parts requires verification that all listed parameters align with the original specification.

Parameter Comparison

No substitute parts are currently available for comparison. When evaluating potential alternatives, the following parameters must be matched or exceeded:

Engineering Selection Recommendations

The FN5045-8-44 is classified as obsolete. When sourcing replacement components, prioritize parts that maintain ROHS3 compliance and cURus certification status. The three-phase delta configuration and 8 A current rating are non-negotiable specifications for regenerative motor drive applications. Ensure any substitute maintains equivalent inductance characteristics (6.9 mH) to preserve EMI suppression performance. Terminal block termination and chassis mount form factor must be preserved to ensure mechanical and electrical compatibility with existing system designs.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the FN5045-8-44? A: A valid substitute must be a three-phase (delta) EMC/EMI line filter with 8 A or higher current rating, chassis mount configuration, terminal block termination, single-stage design, and equivalent inductance. The part must carry cURus approval and maintain ROHS3 compliance.

Q: Why is the FN5045-8-44 classified as obsolete? A: Obsolete status indicates the manufacturer has discontinued production. Equivalent parts from Schaffner EMC Inc. or other recognized EMC filter manufacturers should be evaluated for system redesign or maintenance applications.

Q: Can I use a higher current-rated filter as a substitute? A: Yes, provided all other parameters remain equivalent. A filter rated for 10 A or 16 A can substitute for the 8 A unit if the three-phase delta configuration, mounting type, termination style, and regulatory compliance are maintained.

Q: What is the significance of the 6.9 mH inductance specification? A: Inductance directly affects EMI suppression performance. Substitute parts should maintain equivalent inductance to ensure the same filtering effectiveness in regenerative motor drive circuits.

Q: Are there any packaging considerations for this component? A: The FN5045-8-44 is supplied in box packaging. Verify that substitute parts use compatible packaging for your procurement and assembly processes.

Q: What certifications must a substitute part carry? A: Substitute parts must carry cURus approval (or equivalent recognized certification body approval) and maintain ROHS3 compliance and REACH unaffected status to meet regulatory requirements.
