FN422-2.5-13 Equivalent & Substitute Parts

Part Overview

The FN422-2.5-13 is a single-phase EMC/EMI line filter manufactured by Schaffner EMC Inc., rated for 250VAC at 2.5A with DC to 400Hz operating frequency range. This chassis-mount filter features quick-connect termination and is designed for general-purpose applications requiring electromagnetic compatibility filtering.

The FN422-2.5-13 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, frequency range, mounting configuration, and termination style while meeting equivalent regulatory approvals.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FN422-2.5-13 must satisfy the following criteria:

• Voltage rating of 250VAC (exact match required)
• Single-phase, single-stage configuration
• Chassis-mount with quick-connect termination
• Operating frequency range encompassing DC to 400Hz minimum
• Current rating equal to or greater than 2.5A
• RoHS3 compliance
• Regulatory approvals including CSA and ENEC certification

The PS02/A0320/63 from Bulgin meets these substitution criteria with a 3A current rating (exceeding the 2.5A requirement), 250VAC voltage compatibility, 50 to 400Hz frequency range, and equivalent regulatory certifications.

Parameter Comparison

Engineering Selection Recommendations

The PS02/A0320/63 qualifies as a direct substitute for the FN422-2.5-13 based on electrical and mechanical compatibility. Both components share identical 250VAC voltage ratings, single-phase single-stage architecture, chassis-mount configuration, and quick-connect termination. The Bulgin part provides a higher current rating (3A versus 2.5A), ensuring adequate capacity for the original application.

The PS02/A0320/63 carries Active product status, providing long-term availability and supply chain stability compared to the FN422-2.5-13's "Not For New Designs" classification. Both parts maintain ROHS3 compliance and hold equivalent regulatory certifications from CSA and ENEC. The Bulgin component includes additional UL and VDE approvals and specifies an operating temperature range of -25°C to 85°C.

The inductance values differ (1.8mH for Bulgin versus 3.4mH for Schaffner), reflecting design variations between manufacturers. This parameter difference does not preclude substitution when the application requirements are met by the specified electrical characteristics.

Frequently Asked Questions (FAQ)

Q: Can the PS02/A0320/63 replace the FN422-2.5-13 in existing applications?

A: Yes. Both components meet the core substitution criteria: 250VAC rating, 2.5A minimum current capacity, single-phase single-stage configuration, chassis-mount with quick-connect termination, and equivalent regulatory approvals. The Bulgin part's 3A rating provides additional margin above the original 2.5A specification.

Q: What is the significance of the frequency range difference (DC ~ 400Hz versus 50 ~ 400Hz)?

A: The FN422-2.5-13 specifies DC to 400Hz operation, while the PS02/A0320/63 operates from 50Hz to 400Hz. Applications requiring DC filtering must use the original Schaffner component or identify alternative substitutes with DC-rated specifications.

Q: How do the inductance values affect substitution?

A: Inductance is a design parameter that influences filter performance characteristics. The difference between 3.4mH and 1.8mH reflects manufacturer design choices. Substitution is valid when the application requirements are satisfied by the electrical ratings and certifications provided, not by inductance matching.

Q: Are the regulatory certifications equivalent?

A: Both components hold CSA and ENEC certifications. The PS02/A0320/63 includes additional UL and VDE approvals. For applications requiring specific certification compliance, verify that the substitute part's approval agencies meet system requirements.

Q: What packaging considerations apply to substitution?

A: Both components use chassis-mount configuration with quick-connect termination, ensuring mechanical and electrical interface compatibility. Verify physical dimensions and connector specifications against system integration requirements before final selection.
