Substitute Part Grouping Explanation

The FN351H-110-35 qualifies as a direct substitute for the FN351-110-35 based on the following critical parameters:

Matching Parameters:

• Manufacturer: Schaffner EMC Inc.
• Base Product Series: FN 351
• Filter Type: Three Phase (Delta)
• Configuration: Single Stage
• Current Rating: 110 A
• Frequency Range: DC ~ 60 Hz
• Mounting Type: Chassis Mount
• Termination Style: Terminal Block
• Approval Agencies: CSA, ENEC, UR
• RoHS Compliance: ROHS3 Compliant

Enhanced Parameters in Substitute:

• Voltage - Phase to Ground/Neutral: 300 V (vs. 250 V)
• Voltage - Phase to Phase: 520 V (vs. 440 V)
• Operating Temperature Range: -25°C ~ 100°C (vs. -25°C ~ 85°C)
• Product Status: Active (vs. Obsolete)

The FN351H-110-35 maintains functional equivalence while offering improved voltage ratings and extended temperature operating range, making it suitable for applications requiring the same filtering characteristics with enhanced performance margins.

Parameter Comparison

Engineering Selection Recommendations

The FN351H-110-35 is the recommended substitute for the obsolete FN351-110-35. Both components maintain identical core filtering specifications and hold equivalent regulatory certifications from CSA, ENEC, and UR. The substitute part is currently in active production status, ensuring availability for new designs and replacement applications.

The FN351H-110-35 provides enhanced voltage ratings and extended operating temperature range, which are compatible with applications designed for the original FN351-110-35. These improvements do not introduce incompatibility; rather, they expand the operational envelope while maintaining the same mechanical and electrical interface characteristics.

Frequently Asked Questions (FAQ)

Q: Can the FN351H-110-35 directly replace the FN351-110-35 in existing designs?

A: Yes. Both components share identical mounting type (chassis mount), termination style (terminal block), current rating (110 A), and frequency operating range (DC ~ 60 Hz). The substitute maintains the same three-phase delta filter configuration and single-stage design.

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

A: The FN351H-110-35 features higher voltage ratings (300 V phase-to-ground vs. 250 V; 520 V phase-to-phase vs. 440 V) and an extended operating temperature range (-25°C to 100°C vs. -25°C to 85°C). The substitute is in active production status, whereas the original is obsolete.

Q: Are both parts certified by the same regulatory agencies?

A: Yes. Both the FN351-110-35 and FN351H-110-35 hold approvals from CSA, ENEC, and UR, and both comply with ROHS3 standards.
