Qualtek 854-02/002 Line Filter - Equivalent & Substitute Parts

Part Overview

The Qualtek 854-02/002 is a single-phase EMC/EMI line filter rated for 115V/250VAC at 2A with two-stage configuration and wire lead termination. This chassis-mount filter is designed for general-purpose applications requiring electromagnetic compatibility filtering across 50/60Hz power systems. The product maintains active status with full RoHS3 compliance and international approvals (CSA, UR, VDE). Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Qualtek 854-02/002 is determined by the following critical parameters:

• Filter Type & Configuration: Single-phase, two-stage topology
• Current Rating: 2 A minimum
• Voltage Rating: Must support 250VAC operation (115V operation is secondary)
• Frequency Compatibility: 50/60Hz operation
• Mounting & Termination: Chassis mount with wire lead connections
• Regulatory Compliance: CSA, UR, VDE approvals required
• Environmental Rating: Operating temperature range compatibility

The TE Connectivity Corcom Filters 2VR3 qualifies as a manufacturer-recommended substitute based on matching filter topology, current capacity, voltage rating, frequency range, mounting configuration, termination style, and regulatory certifications.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity Corcom Filters 2VR3 is the manufacturer-recommended substitute for the Qualtek 854-02/002. Both components share identical filter topology, current capacity, voltage rating for 250VAC operation, frequency compatibility, mounting configuration, termination style, and regulatory certifications (CSA, UR, VDE). Both maintain ROHS3 compliance.

Selection between these parts should account for the following differences:

• Voltage Range: The 2VR3 is rated for 250VAC only, whereas the 854-02/002 supports both 115V and 250VAC. Applications requiring 115VAC operation must use the original Qualtek part.
• Operating Temperature: The 854-02/002 operates across -25°C to 85°C, while the 2VR3 is rated -10°C to 40°C. Applications requiring extended low-temperature operation below -10°C or high-temperature operation above 40°C require the original part.
• Inductance: The 2VR3 provides 1.078mH inductance compared to 2.4mH in the 854-02/002. This difference may affect filtering characteristics in specific EMI/EMC applications.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity Corcom 2VR3 replace the Qualtek 854-02/002 in all applications?

A: The 2VR3 is suitable for 250VAC applications operating within -10°C to 40°C. Applications requiring 115VAC operation or extended temperature ranges must use the original Qualtek part.

Q: What is the significance of the inductance difference between these filters?

A: Inductance affects the filter's attenuation characteristics across frequency ranges. The 854-02/002 at 2.4mH and the 2VR3 at 1.078mH provide different filtering profiles. Application-specific EMI/EMC requirements determine which inductance value is appropriate.

Q: Are both parts certified for the same regulatory standards?

A: Yes. Both the Qualtek 854-02/002 and TE Connectivity Corcom 2VR3 carry CSA, UR, and VDE approvals and maintain ROHS3 compliance.

Q: What packaging is available for each part?

A: The Qualtek 854-02/002 is available in standard packaging. The TE Connectivity Corcom 2VR3 is supplied in bulk packaging.

Q: Can these filters be used interchangeably in existing designs?

A: Interchangeability depends on application voltage requirements and operating temperature range. Both parts share identical mounting, termination, and electrical ratings at 250VAC/2A/50-60Hz. Verify that your application does not require 115VAC operation or temperatures outside the -10°C to 40°C range before substituting the 2VR3.
