TE Connectivity Corcom Filters 1609071-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity Corcom Filters 1609071-2 is a three-phase (delta) EMC/EMI line filter rated for 63 A AC operation at 50/60 Hz. This chassis-mounted filter is designed for general-purpose applications requiring single-stage EMI suppression in three-phase power distribution systems. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for continued system support and new procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity Corcom Filters 1609071-2 is determined by the following critical parameters:

Primary Substitution Criteria:

• Filter Type: Three Phase (Delta) configuration
• Configuration: Single Stage topology
• Current Rating: Minimum 63 A (equal or higher)
• Voltage Rating: Phase-to-Phase minimum 440 V AC; Phase-to-Ground minimum 250 V AC
• Frequency Range: 50/60 Hz operation capability
• Mounting Type: Chassis Mount
• Applications: General Purpose or compatible industrial applications

Secondary Considerations:

• Termination style compatibility with system integration requirements
• Operating temperature range suitability for deployment environment
• Regulatory compliance and approval agency certifications
• RoHS compliance status for new procurement requirements

The Schaffner EMC Inc. FN351-64-33 meets the primary substitution criteria with equivalent three-phase delta filtering, single-stage configuration, and current rating of 64 A, which exceeds the 63 A requirement. Voltage ratings of 440 V phase-to-phase and 250 V phase-to-ground are within acceptable operating parameters. The part supports DC ~ 60 Hz operation, encompassing the required 50/60 Hz frequency range.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement Applications:

The Schaffner EMC Inc. FN351-64-33 serves as a functional equivalent for the obsolete TE Connectivity Corcom Filters 1609071-2 in three-phase EMI/EMC line filtering applications. Both parts share identical filter topology (three-phase delta, single-stage configuration) and chassis-mount form factor.

Voltage Rating Consideration:

The FN351-64-33 is rated for 440 V phase-to-phase and 250 V phase-to-ground, compared to the original part's 480 V and 277 V ratings respectively. Systems operating at or below the substitute's voltage ratings are directly compatible. Systems requiring the full 480 V / 277 V rating must be evaluated for alternative solutions.

Termination Compatibility:

The original part features threaded post (3/8-16) termination, while the substitute uses terminal block termination. Integration into existing systems requires mechanical and electrical interface modification or adapter solutions.

Regulatory and Compliance Status:

The FN351-64-33 holds CSA, ENEC, and UR approvals, exceeding the original part's single UR certification. The substitute is ROHS3 compliant, addressing environmental compliance requirements for new procurement and system upgrades. The original part's RoHS non-compliance status restricts its use in regulated markets and new equipment designs.

Current and Frequency Specifications:

The substitute's 64 A rating exceeds the original 63 A requirement, providing operational margin. The DC ~ 60 Hz frequency range encompasses the required 50/60 Hz operation.

Frequently Asked Questions (FAQ)

Q: Can the FN351-64-33 directly replace the 1609071-2 in all applications?

A: Direct replacement is possible for applications operating at or below 440 V phase-to-phase and 250 V phase-to-ground. Termination style differs (terminal block versus threaded post), requiring mechanical interface modification. Voltage rating verification against system specifications is mandatory before substitution.

Q: What is the significance of the current rating difference (63 A versus 64 A)?

A: The substitute's 64 A rating exceeds the original 63 A specification, providing adequate capacity for the intended application. Higher current ratings do not create compatibility issues in filtering applications.

Q: Does the extended operating temperature range of the FN351-64-33 affect substitution suitability?

A: The substitute's -25°C ~ 85°C range exceeds the original -10°C ~ 40°C specification. Extended temperature capability does not compromise substitution compatibility and may provide operational advantages in variable thermal environments.

Q: Why is RoHS compliance status relevant for this substitution?

A: The original part is RoHS non-compliant, restricting procurement for new equipment designs and regulated markets. The substitute's ROHS3 compliance enables use in current regulatory environments and future-proofs system designs against evolving environmental standards.

Q: Are the approval certifications interchangeable between the two parts?

A: Both parts hold UR certification, establishing baseline regulatory equivalence. The substitute's additional CSA and ENEC approvals provide broader geographic and market acceptance. Systems requiring specific certification profiles should verify the substitute meets all applicable standards.

Q: What mechanical modifications are required for termination style conversion?

A: The original threaded post (3/8-16) termination must be adapted to the substitute's terminal block configuration. Integration requires mechanical interface redesign, connector modification, or intermediate adapter solutions specific to system architecture.

Q: Is the frequency range difference (50/60 Hz versus DC ~ 60 Hz) significant?

A: The substitute's extended DC ~ 60 Hz range encompasses the original 50/60 Hz requirement. The broader frequency capability does not create compatibility issues and may support additional application scenarios.
