Qualtek 854-03/004 LINE FILTER 115V/250VAC 3A CHASSIS - Equivalent & Substitute Parts

Part Overview

The Qualtek 854-03/004 is a single-phase EMC/EMI line filter rated for 115V and 250VAC operation at 3A capacity with 50/60Hz frequency support. This chassis-mount filter features wire lead termination and is designed for general-purpose applications requiring electromagnetic compatibility filtering. The part is currently active in production with full inventory availability. Substitute parts may be required due to supply constraints, regional availability, or specific application requirements within the allowable electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Qualtek 854-03/004 is determined by the following critical parameters:

• Filter Type: Single Phase (required match)
• Current Rating: 3 A (required match)
• Frequency Support: 50/60Hz (required match)
• Mounting Type: Chassis Mount (required match)
• Termination Style: Wire Leads (required match)
• Voltage Compatibility: Must support at minimum 250VAC operation
• Approval Agencies: CSA, UR, VDE certifications (required match)
• RoHS Compliance: ROHS3 Compliant (required match)

The TE Connectivity Corcom Filters 3ER3 qualifies as a substitute part because it meets all mandatory electrical parameters (single-phase, 3A, 50/60Hz, 250VAC), maintains identical mounting and termination specifications, holds equivalent regulatory approvals, and maintains ROHS3 compliance. Variations in configuration (two-stage versus single-stage) and inductance values (4.62mH versus 3.2mH) remain within acceptable substitution parameters for general-purpose EMC/EMI filtering applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Qualtek 854-03/004 and TE Connectivity Corcom Filters 3ER3 maintain active product status with full regulatory compliance across CSA, UR, and VDE approval agencies. Both parts are ROHS3 compliant and suitable for general-purpose applications.

Selection between these parts should be based on the following considerations:

• Voltage Range Requirements: The Qualtek 854-03/004 supports both 115V and 250VAC operation, while the 3ER3 is rated for 250VAC only. Applications requiring 115VAC operation must use the Qualtek part.
• Operating Temperature Range: The Qualtek part operates across -25°C to 100°C, providing broader temperature coverage than the 3ER3 (-10°C to 40°C). Applications in extreme temperature environments require the Qualtek specification.
• Inductance Characteristics: The 3ER3 provides slightly higher inductance (4.62mH versus 3.2mH), which may affect filtering performance characteristics in specific frequency ranges.
• Configuration Differences: The 3ER3 features two-stage filtering versus the single-stage design of the Qualtek part, potentially offering enhanced EMI/EMC attenuation.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity Corcom 3ER3 replace the Qualtek 854-03/004 in all applications?

A: The 3ER3 is suitable for applications operating at 250VAC only. Applications requiring 115VAC operation must use the Qualtek 854-03/004. Additionally, applications operating below -10°C or above 40°C require the Qualtek part due to its extended temperature range.

Q: What is the significance of the configuration difference (single-stage versus two-stage)?

A: Configuration refers to the internal filtering network structure. The two-stage design of the 3ER3 may provide different frequency response characteristics compared to the single-stage Qualtek design. Selection should be based on specific EMI/EMC attenuation requirements for the target application.

Q: Are both parts suitable for general-purpose applications?

A: Yes. Both parts are rated for general-purpose applications and hold identical regulatory approvals (CSA, UR, VDE). Selection depends on specific voltage, temperature, and filtering performance requirements.

Q: What packaging is available for each part?

A: The Qualtek 854-03/004 is supplied in standard packaging. The TE Connectivity Corcom 3ER3 is supplied in bag packaging.

Q: Do both parts meet current environmental compliance standards?

A: Yes. Both parts are ROHS3 compliant. The Qualtek part is REACH Unaffected, while the 3ER3 is REACH Affected. Verify REACH compliance requirements for your specific application and region.
