FN256-160-28 Equivalent & Substitute Parts

Part Overview

The FN256-160-28 is a three-phase (Wye) EMC/EMI line filter rated for 160 A with chassis mount configuration and terminal block termination. This component is classified as obsolete, making identification of suitable substitute parts essential for system design and maintenance applications. The filter is designed for general-purpose applications requiring EMI/EMC filtering in three-phase power distribution systems operating at DC ~ 60Hz frequencies.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN256-160-28 is based on the following critical parameters that must remain consistent:

• Filter Type: Three Phase (Wye) configuration
• Current Rating: 160 A
• Mounting Type: Chassis Mount
• Termination Style: Terminal Block
• Operating Frequency: DC ~ 60Hz
• Approval Agencies: CSA, ENEC, UR certification
• Operating Temperature Range: -25°C ~ 100°C
• RoHS Compliance: ROHS3 Compliant

The FN3256H-160-40 qualifies as a substitute part because it maintains all critical electrical and mechanical parameters while offering an active product status with enhanced voltage ratings.

Parameter Comparison

Engineering Selection Recommendations

The FN3256H-160-40 is the qualified substitute for the obsolete FN256-160-28. Both components maintain identical electrical performance specifications for current rating, operating frequency, and temperature range. The substitute part offers enhanced voltage ratings at both phase-to-ground/neutral (300 V vs. 277 V) and phase-to-phase (520 V vs. 480 V) configurations, providing additional design margin in applications operating at or near the original part's voltage limits.

The FN3256H-160-40 holds active product status with full compliance to CSA, ENEC, and UR approval agencies, identical to the original part. Both components are ROHS3 compliant and maintain the same mechanical interface through chassis mount configuration with terminal block termination.

Frequently Asked Questions (FAQ)

Q: Can the FN3256H-160-40 be used as a direct replacement for the FN256-160-28?

A: Yes. Both parts maintain identical current ratings (160 A), filter type (three-phase Wye), configuration (single stage), mounting type (chassis mount), and termination style (terminal block). Operating frequency and temperature ranges are identical. The substitute part features higher voltage ratings, which provides compatibility in all applications where the original part was specified.

Q: What is the primary difference between these two parts?

A: The FN3256H-160-40 is an active product from the FN 3256 series, while the FN256-160-28 is an obsolete part from the FN 256 series. The substitute offers enhanced voltage specifications and current product support.

Q: Are the mechanical dimensions and mounting interfaces identical?

A: Both parts feature chassis mount configuration with terminal block termination. Mechanical compatibility is maintained for standard three-phase filter installations.

Q: Do both parts carry the same regulatory approvals?

A: Yes. Both the FN256-160-28 and FN3256H-160-40 are certified by CSA, ENEC, and UR approval agencies and are ROHS3 compliant.

Q: What packaging is available for the substitute part?

A: The FN3256H-160-40 is supplied in Tray packaging.
