Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN258-16-29 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
• Frequency Range: DC ~ 60Hz operation
• Configuration: Two Stage filtering
• 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 qualifies as a substitute because it maintains identical filter type, current rating, mounting configuration, termination style, frequency range, and two-stage design. The substitute component supports higher voltage ratings (305 V phase-to-ground, 530 V phase-to-phase), which provides compatibility with the original 277 V / 480 V application while offering extended voltage capability.

Parameter Comparison

Engineering Selection Recommendations

The FN3288-16-44-C35-R65 is the designated substitute for the FN258-16-29. Selection of this substitute is supported by the following factors:

• Product Status: The FN3288-16-44-C35-R65 maintains Active status, ensuring ongoing manufacturer support and availability, whereas the FN258-16-29 is classified as Not For New Designs.
• Regulatory Compliance: Both components are ROHS3 Compliant and REACH Unaffected, maintaining equivalent environmental and regulatory standing.
