ELF-22V060B Common Mode Choke Equivalent & Substitute Parts

Part Overview

The ELF-22V060B is a 2-line common mode choke (CMC) manufactured by Panasonic Electronic Components, designed for through-hole mounting applications requiring 6A current handling capability. This component features a typical DC resistance of 27mOhm and is housed in a vertical 4-pin package with dimensions of 32.00mm × 23.00mm × 39.00mm (max height).

The ELF-22V060B is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and new design requirements where this part is specified or functionally required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELF-22V060B requires evaluation based on the following critical parameters:

• Number of Lines: Must remain 2-line configuration for functional compatibility
• Mounting Type: Through-hole mounting is required for PCB integration
• Package Configuration: Vertical 4-pin package format
• Current Rating: The substitute must support the application's current requirements
• DC Resistance: Low DCR is essential for minimal power loss and heat generation
• Electrical Performance: Inductance and frequency response characteristics where specified

The substitute part EV20-1.2-02-3M3 shares the core functional characteristics (2-line CMC, through-hole mounting, vertical 4-pin package) but operates at a reduced current rating of 1.2A compared to the 6A rating of the ELF-22V060B. This substitute is suitable only for applications where the current requirement does not exceed 1.2A.

Parameter Comparison

Engineering Selection Recommendations

Current Application Compatibility: The EV20-1.2-02-3M3 substitute is electrically compatible with the ELF-22V060B only in applications where the maximum current requirement does not exceed 1.2A. Applications requiring the full 6A current rating of the ELF-22V060B cannot use this substitute without risking component failure or thermal stress.

Compliance Status: The EV20-1.2-02-3M3 is ROHS3 compliant and carries active product status, making it suitable for new designs and applications subject to RoHS regulations. The ELF-22V060B is RoHS non-compliant and obsolete, limiting its use to legacy system support or applications with explicit exemptions.

Physical Integration: The EV20-1.2-02-3M3 has a smaller footprint (21.00mm × 16.00mm × 26.00mm max) compared to the ELF-22V060B (32.00mm × 23.00mm × 39.00mm max). PCB layout verification is required to confirm that the reduced dimensions do not create integration conflicts or thermal management issues.

Electrical Performance Trade-offs: The EV20-1.2-02-3M3 exhibits higher DC resistance (127mOhm typical) compared to the ELF-22V060B (27mOhm typical), resulting in increased power dissipation. The substitute provides specified AC voltage rating (250V) and operating temperature range (-25°C ~ 100°C), parameters not provided for the main part.

Frequently Asked Questions (FAQ)

Q: Can the EV20-1.2-02-3M3 directly replace the ELF-22V060B in all applications?

A: No. The EV20-1.2-02-3M3 has a maximum current rating of 1.2A, while the ELF-22V060B is rated for 6A. Substitution is valid only for applications where the actual circuit current does not exceed 1.2A. Exceeding this rating will cause component damage or failure.

Q: What is the impact of the higher DC resistance in the substitute part?

A: The EV20-1.2-02-3M3 has a DC resistance of 127mOhm (typical) compared to 27mOhm (typical) for the ELF-22V060B. This 4.7× increase in resistance results in proportionally higher power dissipation (I²R losses). For low-current applications, this may be acceptable; for high-current or thermally constrained designs, this difference is significant.

Q: Are there physical mounting considerations when switching to the EV20-1.2-02-3M3?

A: Yes. The EV20-1.2-02-3M3 is physically smaller (21.00mm × 16.00mm × 26.00mm max) than the ELF-22V060B (32.00mm × 23.00mm × 39.00mm max). Both use vertical 4-pin through-hole packages, but PCB layout and component spacing must be verified to ensure no conflicts with adjacent components or thermal management requirements.

Q: What compliance advantages does the EV20-1.2-02-3M3 offer?

A: The EV20-1.2-02-3M3 is ROHS3 compliant and carries active product status, making it suitable for new product designs and applications subject to RoHS regulations. The ELF-22V060B is RoHS non-compliant and obsolete, limiting its availability and regulatory acceptance in new applications.

Q: How do the electrical specifications compare for EMI filtering applications?

A: The EV20-1.2-02-3M3 provides specified inductance (3.3 mH @ 400 Hz), AC voltage rating (250V), and operating temperature range (-25°C ~ 100°C). The ELF-22V060B does not provide these specifications in the available documentation. For EMI filtering applications, the EV20-1.2-02-3M3 offers defined performance parameters suitable for power line filtering.
