Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN258L-16-07 is determined by the following critical parameters:

• Filter Type: Three Phase (Delta) configuration
• Current Rating: 16 A nominal
• Mounting Type: Chassis Mount
• Termination Style: Terminal Block
• Configuration: Two Stage
• Frequency Range: DC ~ 60Hz operation
• Voltage Compatibility: Phase-to-ground and phase-to-phase ratings must accommodate the original 277 V and 480 V specifications

The FN3288-16-44-C35-R65 meets all substitution criteria. It maintains identical filter type, current rating, mounting configuration, termination style, and frequency operating range. The voltage ratings of this substitute (305 V phase-to-ground, 530 V phase-to-phase) exceed the original specifications, ensuring compatibility with existing system designs.

Parameter Comparison

Engineering Selection Recommendations

The FN3288-16-44-C35-R65 is the qualified substitute for the FN258L-16-07. Both components are manufactured by Schaffner EMC Inc. and maintain ROHS3 compliance. The substitute part carries Active product status, ensuring ongoing availability and support, whereas the original part is designated Not For New Designs.

The FN3288-16-44-C35-R65 provides enhanced voltage ratings (305 V phase-to-ground and 530 V phase-to-phase) compared to the original (277 V and 480 V respectively), offering improved margin for system voltage variations. The extended operating temperature range (-40°C to 100°C versus -25°C to 100°C) provides additional environmental flexibility.

Both parts maintain identical electrical specifications for current (16 A), frequency range (DC ~ 60Hz), filter topology (three-phase delta, two-stage), and mechanical interface (chassis mount with terminal block termination). These matching parameters ensure functional equivalence in inverter and power drive system applications.

Frequently Asked Questions (FAQ)

Q: Can the FN3288-16-44-C35-R65 directly replace the FN258L-16-07 in existing installations?

A: Yes. Both components share identical filter type, current rating, mounting configuration, termination style, and operating frequency range. The substitute's higher voltage ratings are compatible with systems designed for the original part's 277 V and 480 V specifications.

Q: What is the significance of the "Not For New Designs" status on the FN258L-16-07?

A: This designation indicates the manufacturer has discontinued active development and support for this model. The FN3288-16-44-C35-R65, with Active status, represents the current product line offering equivalent functionality.

Q: Are there packaging differences between these parts?

A: Yes. The FN258L-16-07 is supplied in Tray packaging, while the FN3288-16-44-C35-R65 is supplied in Box packaging. Procurement and storage procedures may require adjustment accordingly.

Q: Do both parts meet the same regulatory approvals?

A: The FN258L-16-07 carries CSA, ENEC, and UR approvals. Approval agency information for the FN3288-16-44-C35-R65 is not provided in the available data. Verification of specific regulatory requirements for your application is necessary.

Q: What is the operating temperature difference between these components?

A: The FN258L-16-07 operates from -25°C to 100°C, while the FN3288-16-44-C35-R65 operates from -40°C to 100°C. The substitute provides a 15°C lower temperature limit, suitable for applications requiring extended cold-temperature performance.
