ELF-22V030C Equivalent & Substitute Parts

Part Overview

The ELF-22V030C is a 2-line common mode choke (CMC) designed for through-hole mounting with a maximum current rating of 3A and typical DC resistance of 91mOhm. Manufactured by Panasonic Electronic Components as part of the V series, this component is classified as obsolete. Due to its discontinued status, identifying equivalent substitute parts is essential for ongoing system maintenance, repair, and new design implementations where this filtering topology is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELF-22V030C is determined by the following critical parameters:

• Number of Lines: Must remain 2-line configuration for common mode filtering topology
• Current Rating: Minimum 3A to maintain electrical performance in the application
• Mounting Type: Through-hole mounting required for PCB compatibility
• Package Configuration: Vertical, 4-pin package for mechanical fit
• DC Resistance: Comparable DCR values to ensure signal integrity and thermal performance

The EV28-3.0-02-9M0-X from Schaffner EMC Inc. qualifies as a substitute based on matching these core electrical and mechanical parameters while maintaining the same functional classification as a 2-line common mode choke.

Parameter Comparison

Engineering Selection Recommendations

The EV28-3.0-02-9M0-X is an active substitute for the obsolete ELF-22V030C. Both components share identical electrical specifications for current rating (3A) and line configuration (2-line CMC), with comparable DC resistance values (91mOhm vs. 115mOhm). The substitute maintains through-hole mounting and vertical 4-pin package compatibility.

The EV28-3.0-02-9M0-X offers additional advantages: active product status ensures ongoing availability, ROHS3 compliance meets current regulatory requirements, and specified operating temperature range (-25°C ~ 100°C) and AC voltage rating (250V) provide documented performance boundaries. The substitute's slightly smaller footprint (29.20mm x 21.00mm vs. 32.00mm x 23.00mm) may require PCB layout verification for mechanical clearance.

Selection of the substitute should be based on application requirements for regulatory compliance and long-term component availability.

Frequently Asked Questions (FAQ)

Q: Can the EV28-3.0-02-9M0-X directly replace the ELF-22V030C in existing designs?

A: Yes, for applications where the 2-line common mode choke topology and 3A current rating are required. Both components share identical electrical specifications and package configuration. PCB layout verification is recommended due to minor dimensional differences (the substitute is slightly smaller).

Q: What is the significance of the DC resistance difference (91mOhm vs. 115mOhm)?

A: The 24mOhm difference represents approximately 26% higher resistance in the substitute. This affects power dissipation and insertion loss characteristics. Applications sensitive to these parameters should evaluate the impact on system performance.

Q: Why is RoHS compliance important for this substitution?

A: The original ELF-22V030C is RoHS non-compliant, while the EV28-3.0-02-9M0-X is ROHS3 compliant. For new designs or systems subject to environmental regulations, the compliant substitute is required. For legacy system repairs, compliance requirements depend on regional regulations and customer specifications.

Q: Are there dimensional constraints for using the EV28-3.0-02-9M0-X?

A: The substitute is smaller in all dimensions: 29.20mm x 21.00mm x 35.70mm (max height) compared to 32.00mm x 23.00mm x 39.00mm. Verify that the reduced footprint does not create clearance issues with adjacent components or mechanical constraints on the PCB.

Q: What is the inductance specification of the substitute?

A: The EV28-3.0-02-9M0-X is specified at 9 mH @ 400 Hz. The original part number does not include inductance data in the provided specifications. Inductance performance should be evaluated against application filtering requirements.
