Qualtek 854-20/021 Line Filter - Equivalent & Substitute Parts

Part Overview

The Qualtek 854-20/021 is a single-phase EMC/EMI line filter rated for 115V/250VAC at 20A with 50/60Hz operation. This chassis-mount filter features a two-stage configuration with threaded post termination (8-32) and is designed for general-purpose applications requiring electromagnetic compatibility filtering. The part is currently active in production with 829 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part becomes unavailable or when design requirements permit alternative sourcing.

Substitute Part Grouping Explanation

Substitution eligibility for the Qualtek 854-20/021 is determined by strict alignment of the following critical parameters:

• Filter Type: Single Phase (required match)
• Configuration: Two Stage (required match)
• Current Rating: 20 A (required match)
• Frequency: 50/60Hz (required match)
• Mounting Type: Chassis Mount (required match)
• Termination Style: Threaded Post (8-32) (required match)
• Voltage Rating: Must support the operating voltage of the application (115V or 250V)
• Approval Agencies: CSA, UR, VDE certification (required match)

The TE Connectivity Corcom Filters 20VR6 meets all mandatory electrical and mechanical parameters for substitution. Both parts share identical filter type, configuration, current capacity, frequency range, mounting method, and termination style. Both carry the same regulatory approvals (CSA, UR, VDE) and comply with ROHS3 and REACH requirements.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity Corcom Filters 20VR6 is qualified as a substitute for the Qualtek 854-20/021 based on matching electrical specifications, mechanical configuration, and regulatory certifications. Both parts are active products with current manufacturing status and carry identical approval agency certifications (CSA, UR, VDE), ensuring compliance with the same standards.

Selection between these parts should account for the following provided specifications:

• Voltage Application: The 854-20/021 supports both 115V and 250V operation, while the 20VR6 is rated for 250V only. For 115V applications, the 854-20/021 is the appropriate choice.
• Temperature Operating Range: The 854-20/021 operates across -25°C to 85°C, while the 20VR6 operates within -10°C to 40°C. Applications requiring extended temperature performance should specify the 854-20/021.
• Inductance Specification: The 854-20/021 provides 1mH inductance compared to 880µH in the 20VR6. Both values are within acceptable filtering parameters for the 20A, 50/60Hz application class.
• Regulatory Compliance: Both parts meet ROHS3 and REACH requirements with identical approval agency certifications, ensuring interchangeability from a compliance perspective.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity Corcom 20VR6 replace the Qualtek 854-20/021 in all applications?

A: The 20VR6 is suitable for 250VAC applications only. If your circuit operates at 115VAC, the 854-20/021 is required. Both parts share identical current capacity (20A), frequency range (50/60Hz), mounting configuration, and regulatory certifications.

Q: What is the difference in inductance between these two filters?

A: The 854-20/021 provides 1mH inductance, while the 20VR6 provides 880µH. Both values are specified for single-phase, two-stage EMC/EMI filtering at 20A. The difference reflects manufacturer design variations within the acceptable performance envelope for this filter class.

Q: Are both parts certified by the same regulatory agencies?

A: Yes. Both the Qualtek 854-20/021 and TE Connectivity Corcom 20VR6 carry CSA, UR, and VDE certifications. Both comply with ROHS3 and are REACH unaffected, ensuring equivalent regulatory standing.

Q: What is the operating temperature limitation for the 20VR6?

A: The 20VR6 operates within -10°C to 40°C, which is narrower than the 854-20/021 range of -25°C to 85°C. Applications requiring operation below -10°C or above 40°C must use the 854-20/021.

Q: Do both filters use the same termination method?

A: Yes. Both parts feature threaded post termination (8-32), enabling direct mechanical and electrical interchange in chassis-mount applications.

Q: What packaging is available for each part?

A: The Qualtek 854-20/021 is available in standard packaging with 829 units in stock. The TE Connectivity Corcom 20VR6 is available in bulk packaging with 755 units in stock.
