FN422-1-13 Equivalent & Substitute Parts

Part Overview

The FN422-1-13 is a single phase EMC/EMI line filter manufactured by Schaffner EMC Inc., rated for 250VAC at 1A with DC to 400Hz operating frequency. This chassis mount filter features quick connect termination and 13mH inductance, designed for general purpose applications. The product is classified as "Not For New Designs," making identification of equivalent alternatives necessary for ongoing maintenance, repair, and legacy system support where this filter type remains in service.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FN422-1-13 is determined by the following critical parameters:

• Single phase filter configuration with single stage topology
• 250VAC rated voltage
• Current rating of 1A or higher (substitute must support or exceed the original 1A requirement)
• DC to 400Hz operating frequency range
• Chassis mount mechanical form factor
• Inductance value within acceptable tolerance (13mH reference)
• ROHS3 compliance and regulatory approvals

The LFIL0000 from Red Lion Controls meets these substitution criteria with compatible electrical specifications and regulatory compliance, though termination style differs from the original quick connect design.

Parameter Comparison

Engineering Selection Recommendations

The LFIL0000 serves as a functional equivalent for the FN422-1-13 based on matching electrical specifications: identical single phase, single stage topology; equivalent 250VAC rating; current capacity of 1.15A exceeds the original 1A requirement; and compatible DC to 400Hz frequency range. Both components maintain ROHS3 compliance and operate within the same mechanical chassis mount category.

The primary distinction is termination style: the FN422-1-13 uses quick connect terminals while the LFIL0000 employs wire leads. This difference requires mechanical and electrical interface adaptation during installation. The LFIL0000 holds active product status, ensuring ongoing availability and support, whereas the FN422-1-13 is designated "Not For New Designs." Regulatory approvals differ between manufacturers (CSA/ENEC/UR versus UL), requiring verification against specific application certification requirements.

Frequently Asked Questions (FAQ)

Q: Can the LFIL0000 directly replace the FN422-1-13 without modification?

A: Electrical substitution is valid based on matching voltage, current, frequency, and filter topology. However, termination style differs: quick connect versus wire leads. Physical installation requires appropriate connector adaptation or rewiring.

Q: Does the 1.15A rating of the LFIL0000 versus 1A of the FN422-1-13 affect compatibility?

A: The higher current rating of the LFIL0000 is acceptable for substitution. The substitute component can safely handle the original 1A load requirement.

Q: Are the inductance values of 13mH and 12mH interchangeable?

A: Both inductance values fall within acceptable tolerance for single stage EMC/EMI line filter applications at this power level. The 1mH difference does not prevent functional substitution.

Q: Which regulatory approvals apply to my application?

A: The FN422-1-13 carries CSA, ENEC, and UR approvals. The LFIL0000 carries UL approval. Verify which certification standard your application requires before selection.

Q: What is the packaging difference between these parts?

A: The FN422-1-13 is supplied in Tray packaging, while the LFIL0000 is supplied in Box packaging. This affects storage, handling, and inventory management but not electrical performance.

Q: Why is the FN422-1-13 marked "Not For New Designs"?

A: This designation indicates the manufacturer has discontinued active development and recommends alternatives for new applications. The LFIL0000 represents an active product line suitable for ongoing system support and new implementations.
