FN422-6.5-13 Equivalent & Substitute Parts

Part Overview

The FN422-6.5-13 is a single-phase EMC/EMI line filter manufactured by Schaffner EMC Inc., rated for 250VAC at 6.5A with DC to 400Hz operating frequency. This chassis-mount filter features quick-connect termination and is designed for general-purpose applications requiring electromagnetic compatibility filtering.

The FN422-6.5-13 carries a "Not For New Designs" product status, making identification of functionally equivalent alternatives necessary for ongoing procurement and new system development. Substitute parts must maintain compatibility across voltage rating, current capacity, mounting configuration, and termination style while meeting equivalent regulatory approvals.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FN422-6.5-13 is determined by the following critical parameters:

Mandatory Compatibility Criteria:

• Single-phase filter configuration
• Single-stage design
• Chassis-mount form factor
• Quick-connect termination interface
• 250VAC voltage rating (minimum)
• Current rating equal to or greater than 6.5A
• Operating frequency range supporting DC to 400Hz operation
• ROHS3 compliance
• Regulatory approvals from CSA, ENEC, or equivalent recognized agencies

The SCHURTER 5500.2634.01 qualifies as a functional substitute based on these parameters. Both parts share identical filter topology, mounting methodology, and termination architecture. The SCHURTER part exceeds the current specification (8A vs. 6.5A) and provides dual voltage rating (125V/250VAC), ensuring compatibility in applications designed for the FN422-6.5-13.

Parameter Comparison

Engineering Selection Recommendations

The SCHURTER 5500.2634.01 is the qualified substitute for the FN422-6.5-13 based on functional equivalence and regulatory compliance alignment.

Selection Basis:

The 5500.2634.01 maintains identical mechanical and electrical architecture (single-phase, single-stage, chassis-mount, quick-connect configuration). The higher current rating (8A) provides operational margin above the 6.5A requirement. Dual voltage rating (125V/250VAC) ensures compatibility across broader application ranges while maintaining the 250VAC specification of the original part.

Regulatory approvals for the 5500.2634.01 (cURus, ENEC, VDE) provide equivalent or superior coverage compared to the FN422-6.5-13 (CSA, ENEC, UR). Both parts maintain ROHS3 compliance and REACH unaffected status.

The primary design consideration is the operating frequency specification. The FN422-6.5-13 supports DC to 400Hz operation, while the 5500.2634.01 is specified for 50/60Hz. Applications requiring DC or extended frequency operation beyond 60Hz must evaluate frequency-dependent performance characteristics against system requirements.

The 5500.2634.01 carries Active product status, ensuring long-term availability and supply continuity compared to the Not For New Designs status of the FN422-6.5-13.

Frequently Asked Questions (FAQ)

Q: Can the SCHURTER 5500.2634.01 directly replace the FN422-6.5-13 in existing designs?

A: Yes, for applications operating at 50/60Hz. Both parts share identical mounting (chassis-mount), termination (quick-connect), filter topology (single-phase, single-stage), and voltage rating (250VAC). The 5500.2634.01 current rating (8A) exceeds the 6.5A requirement. Applications requiring DC or extended frequency operation (DC to 400Hz) must confirm the 50/60Hz specification of the 5500.2634.01 meets system requirements.

Q: What are the key compatibility parameters for substitution?

A: Substitution requires matching filter type (single-phase), configuration (single-stage), mounting method (chassis-mount), termination interface (quick-connect), voltage rating (minimum 250VAC), current capacity (minimum 6.5A), and regulatory compliance (CSA, ENEC, UR, or equivalent). Operating frequency range and inductance specifications should be evaluated against application requirements.

Q: Does the dual voltage rating (125V/250VAC) of the 5500.2634.01 affect compatibility?

A: No. The dual voltage rating of the 5500.2634.01 provides additional flexibility. The part operates correctly at the 250VAC specification of the FN422-6.5-13. The 125V capability expands application range without compromising 250VAC performance.

Q: Are there packaging differences between these parts?

A: Yes. The FN422-6.5-13 is supplied in Tray packaging, while the 5500.2634.01 is supplied in Box packaging. Packaging format does not affect electrical or mechanical compatibility but may influence logistics and storage considerations.

Q: What regulatory approvals should be verified for my application?

A: Confirm that your application requirements are met by the regulatory agencies listed for your selected part. The FN422-6.5-13 carries CSA, ENEC, and UR approvals. The 5500.2634.01 carries cURus, ENEC, and VDE approvals. ENEC approval is common to both. Verify that cURus, VDE, or UR coverage aligns with your regional or customer requirements.
