Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN351-36-47 is determined by strict equivalence across the following critical parameters:

• Filter topology: Three-phase delta configuration
• Current capacity: 36 A rating
• Voltage specifications: 250 V phase-to-ground and 440 V phase-to-phase
• Operating frequency: DC to 60 Hz capability
• Mounting and termination: Chassis mount with terminal block interface
• Environmental rating: -25°C to 85°C operating range
• Regulatory compliance: CSA, ENEC, and UR certifications

The FN351-36-33 meets all these criteria and shares the same base product number (FN 351) and series designation, confirming functional interchangeability within the FN 351 product family.

Parameter Comparison

Engineering Selection Recommendations

The FN351-36-33 is a direct functional equivalent to the FN351-36-47. Both parts maintain identical electrical specifications, mechanical interfaces, and regulatory certifications. Selection between these parts should be based on availability and application context. The FN351-36-47 carries "Not For New Designs" status, while the FN351-36-33 is marked as "Obsolete." For legacy system maintenance where the FN351-36-47 is currently installed, the FN351-36-33 provides equivalent performance. Both parts satisfy CSA, ENEC, and UR compliance requirements and maintain ROHS3 and REACH compliance status.

Frequently Asked Questions (FAQ)

Q: Can FN351-36-33 be used as a direct replacement for FN351-36-47?

A: Yes. Both parts are three-phase delta EMC/EMI line filters with identical 36 A current ratings, 250 V phase-to-ground and 440 V phase-to-phase voltage specifications, DC to 60 Hz frequency capability, and terminal block chassis-mount configuration. All electrical and mechanical parameters are equivalent.

Q: What is the difference between "Not For New Designs" and "Obsolete" status?

A: "Not For New Designs" indicates the manufacturer has superseded the part in their current portfolio but may continue limited production. "Obsolete" indicates the part is no longer manufactured. Both statuses indicate these are legacy components; however, both remain functionally identical for replacement applications.

Q: Are the regulatory certifications identical between these parts?

A: Yes. Both FN351-36-47 and FN351-36-33 carry CSA, ENEC, and UR approvals. Both maintain ROHS3 compliance and REACH unaffected status.

Q: Will the FN351-36-33 fit in the same mounting location as the FN351-36-47?

A: Yes. Both parts feature identical chassis-mount configuration with terminal block termination, ensuring mechanical and electrical interface compatibility.

Q: Are there any differences in operating temperature range?

A: No. Both parts operate across the identical -25°C to 85°C temperature range.
