FN351-64-47 Equivalent & Substitute Parts

Part Overview

The FN351-64-47 is a three-phase delta EMC/EMI line filter rated for 64 A with chassis mount configuration and terminal block termination. This component is designed for inverters and power drive systems operating at DC ~ 60Hz with phase-to-ground/neutral voltage of 250 V and phase-to-phase voltage of 440 V. The part is currently obsolete, necessitating identification of equivalent substitute components that maintain identical electrical and mechanical specifications for continued system operation and maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN351-64-47 is determined by strict equivalence across the following critical parameters:

• Filter Type: Three Phase (Delta)
• Current Rating: 64 A
• Voltage - Phase to Ground/Neutral: 250 V
• Voltage - Phase to Phase: 440 V
• Frequency - Operating: DC ~ 60Hz
• Configuration: Single Stage
• Mounting Type: Chassis Mount
• Termination Style: Terminal Block
• Operating Temperature Range: -25°C ~ 85°C
• Approval Agencies: CSA, ENEC, UR

The FN351-64-33 and FN351-64-34 meet all these criteria and are therefore direct substitutes. Both components are members of the FN 351 series and maintain identical electrical ratings, thermal specifications, and regulatory certifications.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using FN351-64-47, the FN351-64-34 is the preferred substitute due to its active product status. This part maintains full electrical and mechanical compatibility while ensuring continued manufacturer support and availability.

The FN351-64-33 is an equivalent alternative that meets all functional requirements. However, this part shares obsolete status with the original component, making it suitable only when FN351-64-34 availability is constrained.

Both substitutes carry ROHS3 compliance, exceeding the RoHS compliance level of the original part, and maintain all required regulatory certifications (CSA, ENEC, UR).

Frequently Asked Questions (FAQ)

Q: Can FN351-64-33 and FN351-64-34 be used interchangeably with FN351-64-47?

A: Yes. Both parts are direct substitutes with identical electrical ratings (64 A, 250 V phase-to-ground, 440 V phase-to-phase), filter configuration (three-phase delta, single stage), mounting specifications (chassis mount, terminal block), and operating parameters (DC ~ 60Hz, -25°C ~ 85°C).

Q: What is the difference between FN351-64-33 and FN351-64-34?

A: The primary difference is product status. FN351-64-34 is active, while FN351-64-33 is obsolete. Both parts are electrically and mechanically identical. FN351-64-34 is recommended for new designs and ongoing procurement due to manufacturer support.

Q: Are there packaging differences between these parts?

A: The original FN351-64-47 was supplied without specified packaging. Both FN351-64-33 and FN351-64-34 are supplied in trays. Packaging does not affect electrical or mechanical compatibility.

Q: Do the substitutes maintain the same regulatory certifications?

A: Yes. All three parts carry CSA, ENEC, and UR approvals. The substitutes additionally meet ROHS3 compliance, which is compatible with systems designed for RoHS compliance.

Q: Which substitute should be selected for new procurement?

A: FN351-64-34 is the recommended selection due to active product status and ongoing manufacturer availability.
