Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN3258-16-45 is determined by the following critical parameters:

• Filter Type: Three Phase (Delta) configuration
• Current Rating: 16 A
• Voltage Rating: 277 V AC (phase to ground/neutral) and 480 V AC (phase to phase)
• Frequency Range: DC ~ 60 Hz operation
• Mounting Type: Chassis Mount
• Termination Style: Terminal Block
• Operating Temperature Range: -25°C ~ 100°C
• Approval Certifications: CSA, ENEC, UR compliance

The FN3258-16-44 meets all these critical parameters and belongs to the same FN 3258 series, establishing it as a direct substitute. The primary distinction is product status and packaging configuration.

Parameter Comparison

Engineering Selection Recommendations

The FN3258-16-44 is the direct substitute for the obsolete FN3258-16-45. Both components maintain identical electrical and mechanical specifications across all critical parameters: three-phase delta configuration, 16 A current rating, 277 V phase-to-ground and 480 V phase-to-phase voltage ratings, and DC to 60 Hz frequency operation.

The FN3258-16-44 carries active product status, ensuring ongoing availability and manufacturer support. Both parts hold equivalent international certifications (CSA, ENEC, UR) and meet RoHS compliance requirements. The FN3258-16-44 achieves ROHS3 compliance, representing an enhanced compliance level compared to the standard RoHS designation of the original part.

Packaging differs between the two parts: the FN3258-16-45 uses standard packaging while the FN3258-16-44 is supplied in tray packaging. This distinction affects procurement and handling procedures but does not impact functional or electrical performance.

Frequently Asked Questions (FAQ)

Q: Can the FN3258-16-44 directly replace the FN3258-16-45 in existing applications?

A: Yes. Both parts share identical electrical ratings (16 A, 277 V phase-to-ground, 480 V phase-to-phase), frequency range (DC ~ 60 Hz), filter configuration (three-phase delta, single stage), mounting type (chassis mount), and termination style (terminal block). Operating temperature range and approval certifications are also equivalent.

Q: What is the significance of the product status difference?

A: The FN3258-16-45 is classified as obsolete, indicating discontinued manufacturing and limited availability. The FN3258-16-44 maintains active status, ensuring continued production, technical support, and reliable procurement channels.

Q: Does packaging affect compatibility?

A: Packaging differences (standard versus tray) do not affect electrical or mechanical compatibility. Packaging selection depends on procurement requirements, storage conditions, and handling procedures specific to your supply chain.

Q: Are the RoHS compliance levels equivalent?

A: Both parts meet RoHS requirements. The FN3258-16-44 achieves ROHS3 compliance, which represents an enhanced compliance standard. This upgrade does not impact functional performance but indicates improved environmental and regulatory alignment.

Q: What certifications apply to both parts?

A: Both the FN3258-16-45 and FN3258-16-44 hold approval from CSA, ENEC, and UR agencies, ensuring compliance with North American, European, and international safety standards for EMC/EMI line filters.
