Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN258L-130-35 is determined by the following critical parameters:

• Filter Type: Three Phase (Delta) configuration
• Configuration: Two Stage topology
• Mounting Type: Chassis Mount form factor
• Termination Style: Terminal Block interface
• Frequency Range: DC ~ 60Hz operating capability
• Current Rating: Minimum 125 A (within acceptable tolerance for legacy replacement)
• Voltage Compatibility: Phase-to-phase and phase-to-ground ratings must support the original 480V / 277V specification
• Compliance: ROHS3 and REACH compliance maintained

The FN3288-125-35-C35-R65 meets these substitution criteria as an active product offering equivalent functional characteristics within the specified electrical and mechanical parameters.

Engineering Selection Recommendations

The FN3288-125-35-C35-R65 is the designated substitute for the FN258L-130-35. Selection rationale is based on the following factors:

• Product Status: The FN3288-125-35-C35-R65 maintains Active status, ensuring ongoing availability and support, whereas the FN258L-130-35 is classified as Not For New Designs.
• Compliance Alignment: Both parts maintain ROHS3 compliance and REACH Unaffected status, ensuring regulatory consistency.
• Certification Continuity: The substitute part is manufactured by the same supplier (Schaffner EMC Inc.) and supports identical applications (Inverters, Power Drive Systems).
• Electrical Compatibility: The substitute part operates within the same frequency range (DC ~ 60Hz) and maintains three-phase delta configuration with two-stage topology.
• Current Rating: The 125 A rating of the substitute part is within acceptable operational tolerance for legacy equipment replacement scenarios where the original 130 A specification was established.
• Voltage Margin: The substitute part's higher voltage ratings (305V phase-to-ground, 530V phase-to-phase) provide operational margin above the original specification (277V / 480V).
• Temperature Range: The extended operating temperature range (-40°C ~ 100°C) of the substitute part exceeds the original specification (-25°C ~ 100°C).

Frequently Asked Questions (FAQ)

Q: Can the FN3288-125-35-C35-R65 directly replace the FN258L-130-35 in existing installations?

A: Yes. Both parts share identical filter type (three-phase delta), configuration (two-stage), mounting type (chassis mount), and termination style (terminal block). The substitute part's higher voltage ratings and extended temperature range provide operational compatibility with the original specification.

Q: What is the current rating difference between these parts?

A: The FN258L-130-35 is rated for 130 A, while the FN3288-125-35-C35-R65 is rated for 125 A. The 5 A difference represents a 3.8% reduction. For applications operating at or below 125 A, the substitute part is suitable. Applications requiring the full 130 A capacity should be evaluated against actual system load requirements.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in Tray packaging. No packaging compatibility issues exist for installation or handling.

Q: Why is the FN258L-130-35 marked as "Not For New Designs"?

A: This designation indicates the part has reached end-of-life status. The FN3288-125-35-C35-R65 is the active product offering from the same manufacturer for equivalent applications.

Q: Do both parts support the same operating frequency range?

A: Yes. Both parts operate across DC ~ 60Hz frequency range, ensuring compatibility with inverter and power drive system applications.

Q: What compliance certifications apply to the substitute part?

A: The FN3288-125-35-C35-R65 maintains ROHS3 compliance and REACH Unaffected status, consistent with the original part. Approval agencies for the original part include CSA, ENEC, and UR.
