ELF-22V060A Common Mode Choke Equivalent & Substitute Parts

Part Overview

The ELF-22V060A 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 25mOhm and is housed in a vertical 4-pin package with dimensions of 32.00mm × 23.00mm × 39.00mm (max height).

The ELF-22V060A 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-22V060A requires evaluation based on the following critical parameters:

• Number of Lines: Must remain 2-line configuration for functional equivalence
• Mounting Type: Through-hole mounting is required for PCB compatibility
• Package Configuration: Vertical 4-pin package format must be maintained
• Current Rating: The substitute must support the application's current requirements
• DC Resistance: Lower DCR values indicate improved efficiency and reduced power dissipation

The identified substitute part, EV20-1.2-02-3M3 (Schaffner EMC Inc.), shares the core functional topology (2-line CMC, through-hole, vertical 4-pin package) but operates at a reduced current rating of 1.2A compared to the original 6A specification. This substitute is suitable only for applications where the actual current demand does not exceed 1.2A.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring 6A current capacity: The ELF-22V060A is the specified component. No direct equivalent with identical 6A rating is available in the provided substitute list. Alternative sourcing channels or design modification may be required.

For applications with current requirements ≤ 1.2A: The EV20-1.2-02-3M3 is a functional substitute. This part offers the following advantages:

• Active product status ensures ongoing availability and supply chain support
• ROHS3 compliance meets modern environmental and regulatory requirements
• Smaller physical footprint (21.00mm × 16.00mm × 26.00mm) may provide PCB layout benefits
• Specified AC voltage rating (250V) and operating temperature range (-25°C ~ 100°C) provide documented performance boundaries

Compliance consideration: The ELF-22V060A is RoHS non-compliant. If RoHS compliance is a design requirement, the EV20-1.2-02-3M3 substitute satisfies ROHS3 compliance standards.

Frequently Asked Questions (FAQ)

Q: Can the EV20-1.2-02-3M3 replace the ELF-22V060A in all applications?

A: No. The EV20-1.2-02-3M3 has a maximum current rating of 1.2A, while the ELF-22V060A is rated for 6A. Substitution is valid only when the actual circuit current does not exceed 1.2A. Operating the substitute above its current rating will result in component failure and potential circuit damage.

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

A: The EV20-1.2-02-3M3 exhibits 127mOhm typical DCR compared to 25mOhm in the ELF-22V060A. At equivalent current levels, higher DCR results in increased power dissipation (I²R losses). For low-current applications (≤1.2A), this difference is typically acceptable but should be evaluated in thermal-sensitive designs.

Q: Are the physical dimensions compatible with existing PCB layouts?

A: The EV20-1.2-02-3M3 is smaller (21.00mm × 16.00mm × 26.00mm) than the ELF-22V060A (32.00mm × 23.00mm × 39.00mm). Both use vertical 4-pin through-hole packages. Verify that the reduced footprint does not conflict with existing PCB routing or component placement constraints. The smaller size may allow improved layout efficiency.

Q: What is the significance of the RoHS compliance difference?

A: The ELF-22V060A is RoHS non-compliant, while the EV20-1.2-02-3M3 is ROHS3 compliant. If the application or end-market requires RoHS compliance (common in EU and many industrial applications), only the EV20-1.2-02-3M3 meets this requirement. RoHS compliance restricts hazardous substances in component manufacturing.

Q: Is the 250V AC rating of the substitute sufficient for my application?

A: The EV20-1.2-02-3M3 is rated for 250V AC. Verify that your circuit voltage does not exceed this specification. The original ELF-22V060A does not specify an AC voltage rating in the provided data, so direct comparison is not possible. Consult the original design specifications to confirm voltage compatibility.
