Key Parameters

Substitute Part Grouping Explanation

The FN3258H-7-44 qualifies as a direct substitute for the FN3258H-7-45 based on the following critical parameters:

• Filter Type & Configuration: Both are three-phase delta EMC/EMI line filters with single-stage configuration
• Current Rating: Both rated for 7 A operation
• Voltage Specifications: Both rated 300 V phase-to-ground/neutral and 520 V phase-to-phase
• Frequency Range: Both operate across DC to 60 Hz
• Mounting & Termination: Both use chassis mount with terminal block termination
• Operating Temperature: Both rated -25°C to 100°C
• Approval Certifications: Both hold CSA, ENEC, and UR approvals
• Series Designation: Both belong to the FN 3258 series

The primary distinction is product status: FN3258H-7-45 is obsolete while FN3258H-7-44 is active, with improved RoHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

The FN3258H-7-44 is the appropriate selection for applications currently specified with FN3258H-7-45. Both components maintain identical electrical and mechanical specifications across all critical parameters: current capacity, voltage ratings, frequency range, mounting configuration, and termination style.

The FN3258H-7-44 offers the advantage of active product status with current manufacturing support and improved RoHS3 compliance designation. Both components carry equivalent regulatory approvals (CSA, ENEC, UR) suitable for the same application environments.

Frequently Asked Questions (FAQ)

Q: Can FN3258H-7-44 directly replace FN3258H-7-45 in existing designs?

A: Yes. Both components share identical electrical ratings (7 A, 300 V phase-to-ground, 520 V phase-to-phase), frequency range (DC to 60 Hz), mounting type (chassis mount), and termination style (terminal block). No circuit modifications are required.

Q: What is the difference between RoHS and RoHS3 compliance?

A: RoHS3 represents the current regulatory standard with updated substance restrictions. Both designations indicate compliance with hazardous substance limitations; RoHS3 reflects the active compliance status of FN3258H-7-44.

Q: Does packaging differ between these parts?

A: FN3258H-7-45 packaging is unspecified in available data. FN3258H-7-44 is supplied in tray packaging. Confirm packaging requirements with your procurement specifications.

Q: Are the approval certifications equivalent?

A: Yes. Both components hold identical approvals from CSA, ENEC, and UR, meeting the same regulatory requirements for three-phase EMC/EMI filtering applications.

Q: Why is FN3258H-7-45 listed as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. FN3258H-7-44 represents the active equivalent within the same FN 3258 series, ensuring continued availability and support.
