Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN258-16-07 is determined by the following critical parameters:

• Filter Type: Three Phase (Delta) configuration required
• Current Rating: 16 A minimum capacity
• Voltage Compatibility: Phase-to-phase voltage of 480 V and phase-to-ground voltage of 277 V
• Operating Frequency: DC ~ 60Hz range
• Mounting Configuration: Chassis mount with terminal block termination
• Environmental Compliance: ROHS3 compliance and regulatory approvals

The FN3288-16-44-C35-R65 satisfies these substitution criteria through equivalent electrical ratings and mechanical form factor compatibility.

Parameter Comparison

Engineering Selection Recommendations

The FN3288-16-44-C35-R65 is the designated substitute for the FN258-16-07. This substitution is supported by:

• Identical current rating (16 A) and three-phase delta filter topology
• Equivalent operating frequency range (DC ~ 60Hz)
• Matching mechanical interface (chassis mount, terminal block termination)
• Higher voltage ratings (530 V phase-to-phase, 305 V phase-to-ground) that encompass the original 480 V / 277 V specifications
• Extended operating temperature range (-40°C to 100°C versus -25°C to 100°C)
• Active product status with current manufacturing support
• Maintained regulatory compliance (ROHS3, REACH Unaffected, EAR99)

The FN3288-16-44-C35-R65 provides enhanced performance margins and extended environmental operating capability while maintaining full electrical and mechanical compatibility with existing FN258-16-07 installations.

Frequently Asked Questions (FAQ)

Q: Can the FN3288-16-44-C35-R65 be used as a direct replacement for the FN258-16-07?

A: Yes. Both components share identical current ratings (16 A), filter topology (three-phase delta), operating frequency (DC ~ 60Hz), and mechanical interfaces (chassis mount, terminal block). The substitute has higher voltage ratings and an extended temperature range, making it suitable for the same applications.

Q: What is the difference in voltage ratings between these two filters?

A: The FN258-16-07 is rated for 480 V phase-to-phase and 277 V phase-to-ground. The FN3288-16-44-C35-R65 is rated for 530 V phase-to-phase and 305 V phase-to-ground. The substitute's higher ratings provide additional safety margin in the same operating environment.

Q: Why is the FN258-16-07 marked as "Not For New Designs"?

A: This designation indicates the component has been superseded by newer models in the manufacturer's portfolio. The FN3288-16-44-C35-R65 represents the current active alternative with equivalent functionality and improved specifications.

Q: Are there packaging differences between these parts?

A: Yes. The FN258-16-07 is supplied in Tray packaging, while the FN3288-16-44-C35-R65 is supplied in Box packaging. This affects storage and handling but does not impact electrical or mechanical compatibility.

Q: Do both filters have the same regulatory approvals?

A: The FN258-16-07 carries CSA, ENEC, and UR approvals. The FN3288-16-44-C35-R65 maintains ROHS3 compliance and REACH Unaffected status. Both are classified as EAR99 for export control purposes.

Q: What is the operating temperature range difference?

A: The FN258-16-07 operates from -25°C to 100°C. The FN3288-16-44-C35-R65 operates from -40°C to 100°C, providing a 15°C lower temperature capability for cold environment applications.
