Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN258P-100-35 is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Filter Type: Three Phase (Delta) configuration
• Current Rating: 100 A
• Configuration: Two Stage
• Frequency Range: DC ~ 60Hz operation
• Voltage Rating: Phase-to-phase and phase-to-ground specifications must accommodate the application voltage

Mechanical Compatibility Requirements:

• Mounting Type: Chassis Mount
• Termination Style: Terminal Block
• Operating Temperature Range: Must support the application environment

Regulatory & Compliance Requirements:

• RoHS3 Compliance
• Regulatory Approvals: CSA, ENEC, UR certifications

The FN3288-100-35-C35-R65 qualifies as a substitute because it maintains identical filter type, current rating, configuration, frequency range, mounting type, and termination style. The substitute operates at higher voltage ratings (530V phase-to-phase, 305V phase-to-ground) and extended temperature range (-40°C ~ 100°C), making it suitable for applications requiring the FN258P-100-35 specifications while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The FN3288-100-35-C35-R65 is the designated substitute for the FN258P-100-35. Selection of the substitute is justified by the following factors:

Product Status: The FN258P-100-35 carries Not For New Designs status, indicating manufacturer discontinuation. The FN3288-100-35-C35-R65 maintains Active product status, ensuring ongoing availability, technical support, and supply chain reliability.

Electrical Equivalence: Both filters maintain identical three-phase (Delta) configuration, 100 A current rating, two-stage design, and DC ~ 60Hz frequency range. The substitute's higher voltage ratings (530V phase-to-phase, 305V phase-to-ground) provide enhanced capability for applications operating at or below the original 480V/277V specifications.

Mechanical Compatibility: Chassis mount configuration and terminal block termination are preserved, enabling direct mechanical integration without redesign.

Compliance: Both components maintain ROHS3 compliance. The substitute supports extended operating temperature range (-40°C ~ 100°C versus -25°C ~ 100°C), providing broader environmental suitability.

Frequently Asked Questions (FAQ)

Q: Can the FN3288-100-35-C35-R65 directly replace the FN258P-100-35 in existing applications?

A: Yes, provided the application voltage does not exceed 480V phase-to-phase or 277V phase-to-ground. The substitute's higher voltage ratings ensure compatibility with the original specifications while offering improved availability and active product support.

Q: What are the key differences between these two filters?

A: The primary differences are product status (Not For New Designs versus Active), voltage ratings (480V/277V versus 530V/305V), and operating temperature range (-25°C ~ 100°C versus -40°C ~ 100°C). All critical electrical and mechanical parameters remain equivalent.

Q: Are there any packaging or inventory considerations?

A: Both components are supplied in Tray packaging. The FN3288-100-35-C35-R65 currently has higher inventory availability (1084 Pcs) compared to the FN258P-100-35 (752 Pcs), supporting supply chain continuity.

Q: Do both filters support the same applications?

A: Yes. Both are specified for Inverters and Power Drive Systems applications with identical frequency and current handling capabilities.

Q: What compliance certifications apply to the substitute?

A: The FN3288-100-35-C35-R65 maintains ROHS3 compliance and REACH Unaffected status. Specific regulatory approvals (CSA, ENEC, UR) should be verified with the manufacturer for the substitute model if these certifications are required for the application.
