Substitute Part Grouping Explanation

Substitution of the 1609071-3 is determined by the following critical parameters:

Primary Substitution Criteria:

• Filter Type: Three Phase (Delta) configuration
• Current Rating: Minimum 100 A (equal or higher)
• Voltage Rating: Phase-to-Phase minimum 440 V; Phase-to-Ground minimum 250 V
• Configuration: Single Stage
• Mounting Type: Chassis Mount
• Frequency Operating Range: 50/60 Hz or DC ~ 60 Hz capability
• Termination compatibility with system integration requirements

Identified Substitute Parts:

The FN351-110-35 (Schaffner EMC Inc.) qualifies as a functional equivalent based on matching filter type, three-phase delta configuration, single-stage design, chassis-mount construction, and current rating of 110 A, which exceeds the 100 A requirement. Operating frequency range extends to DC ~ 60 Hz, providing broader application flexibility.

The B85321A2205A101 (EPCOS - TDK Electronics) is a feed-through capacitor component rated for 100 A at 600 V, suitable for applications requiring individual filtering element replacement or component-level substitution within larger filter assemblies.

Parameter Comparison

Engineering Selection Recommendations

FN351-110-35 (Schaffner EMC Inc.):

The FN351-110-35 represents the closest functional equivalent to the 1609071-3. Both components are three-phase delta EMC/EMI line filters with single-stage configuration and chassis-mount construction. The FN351-110-35 provides a 10 A current rating margin above the 100 A requirement and operates across a broader frequency range (DC ~ 60 Hz versus 50/60 Hz). The FN351-110-35 achieves ROHS3 compliance and carries CSA, ENEC, and UR approvals, providing enhanced regulatory standing compared to the non-compliant 1609071-3. Termination style differs (terminal block versus threaded post), requiring mechanical integration assessment. Operating temperature range extends to 85°C, exceeding the 1609071-3 specification.

B85321A2205A101 (EPCOS - TDK Electronics):

The B85321A2205A101 is an active-status feed-through capacitor component suitable for component-level substitution within filter assemblies or standalone filtering applications. This part maintains the 100 A current rating and provides 600 V voltage rating, exceeding the 480 V phase-to-phase requirement of the 1609071-3. ROHS3 compliance and REACH affected status indicate modern manufacturing standards. This component is appropriate for applications requiring individual filtering element replacement rather than complete filter assembly substitution. Through-hole mounting and axial-threaded terminal configuration differ from the chassis-mount threaded-post design of the 1609071-3.

Frequently Asked Questions (FAQ)

Q: Can the FN351-110-35 directly replace the 1609071-3 in existing installations?

A: The FN351-110-35 provides equivalent three-phase delta EMC/EMI filtering functionality with superior current capacity (110 A versus 100 A) and broader frequency operating range. However, termination style differs (terminal block versus threaded post 3/8-16), requiring mechanical integration verification and potential connector adaptation.

Q: What is the primary difference between the FN351-110-35 and B85321A2205A101 substitutes?

A: The FN351-110-35 is a complete three-phase delta line filter assembly equivalent to the 1609071-3, providing integrated EMC/EMI filtering. The B85321A2205A101 is a feed-through capacitor component suitable for component-level replacement within filter circuits or standalone capacitive filtering applications. Selection depends on whether complete filter assembly replacement or individual component substitution is required.

Q: Are there compliance considerations when substituting the 1609071-3?

A: The 1609071-3 is RoHS non-compliant. Both substitute parts (FN351-110-35 and B85321A2205A101) achieve ROHS3 compliance. Systems requiring RoHS compliance must implement the FN351-110-35 or B85321A2205A101. The FN351-110-35 additionally carries CSA, ENEC, and UR approvals, providing broader regulatory certification coverage.

Q: How do voltage ratings compare across these parts?

A: The 1609071-3 is rated 480 V phase-to-phase and 277 V phase-to-ground. The FN351-110-35 is rated 440 V phase-to-phase and 250 V phase-to-ground, representing a 40 V and 27 V reduction respectively. The B85321A2205A101 is rated 600 V, exceeding all phase-to-phase requirements. Voltage margin assessment is necessary for specific application conditions.

Q: What mounting and termination differences exist?

A: All three parts feature chassis-mount construction. The 1609071-3 uses threaded post (3/8-16) termination. The FN351-110-35 uses terminal block termination. The B85321A2205A101 uses axial-threaded terminal configuration. Mechanical integration and connector compatibility must be evaluated for each substitution scenario.

Q: Does operating temperature range affect substitution suitability?

A: The 1609071-3 operates -10°C to 40°C. The FN351-110-35 operates -25°C to 85°C, providing extended low-temperature capability and significantly higher high-temperature rating. The B85321A2205A101 operates -40°C to 85°C. Applications requiring operation beyond the 1609071-3 temperature envelope benefit from the extended ranges of substitute parts.

Q: Can the B85321A2205A101 be used in three-phase systems?

A: The B85321A2205A101 is a single feed-through capacitor component. Three-phase delta filtering requires three capacitive elements configured appropriately. This component is suitable for single-phase applications or as a replacement element within a larger three-phase filter assembly, not as a standalone three-phase filter replacement.
