ELF-22V030A Equivalent & Substitute Parts

Part Overview

The ELF-22V030A is a 2-line common mode choke (CMC) with through-hole mounting, rated for 3A maximum current and 85mOhm typical DC resistance. Manufactured by Panasonic Electronic Components as part of the V series, this component is classified as obsolete. Due to its discontinued status, identifying equivalent and substitute parts from active manufacturers is essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ELF-22V030A is determined by the following core parameters:

• Number of Lines: Must remain 2-line configuration
• Mounting Type: Must be through-hole
• Package Configuration: 4 PC pin vertical or horizontal orientation
• Current Rating: Minimum 3A capability
• DC Resistance: Comparable performance within typical operating range

The two identified substitute parts meet these criteria with the following considerations:

EV35-3.0-02-10M (Schaffner EMC Inc.): Matches 2-line, through-hole, 3A rating, and 4 PC pin vertical configuration. Active product status with ROHS3 compliance.

RD5122-6-9M6 (Schaffner EMC Inc.): Matches 2-line, through-hole, and 4 PC pin configuration with higher current rating (6A). Horizontal mounting orientation differs from original. Active product status with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

EV35-3.0-02-10M is the primary substitute for direct replacement applications. It maintains identical electrical ratings (3A, 2-line configuration), matching package orientation (vertical, 4 PC pin), and offers improved DC resistance (72mOhm vs. 85mOhm). The part is active with ROHS3 compliance, supporting modern regulatory requirements. Physical dimensions are slightly larger but remain within typical PCB layout tolerances.

RD5122-6-9M6 serves as an alternative for applications requiring higher current capacity (6A) or enhanced thermal performance. The horizontal mounting orientation requires PCB layout modification. This part provides superior DC resistance (52.55mOhm) and extended operating temperature range (-25°C ~ 110°C). ROHS3 compliance and higher voltage ratings (600V AC, 850V DC) support demanding power line filtering applications.

Both substitute parts are manufactured by Schaffner EMC Inc., an established supplier of EMC filtering components, and carry active product status with full regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can EV35-3.0-02-10M directly replace ELF-22V030A without PCB modification?

A: Yes. EV35-3.0-02-10M maintains the same 2-line configuration, 3A current rating, through-hole mounting, and vertical 4 PC pin package orientation. Physical dimensions are slightly larger (36.00mm x 24.50mm vs. 32.00mm x 23.00mm), requiring verification of available PCB space.

Q: What is the primary difference between EV35-3.0-02-10M and RD5122-6-9M6?

A: EV35-3.0-02-10M matches the original 3A rating and vertical mounting. RD5122-6-9M6 provides higher current capacity (6A), lower DC resistance (52.55mOhm), and horizontal mounting orientation, requiring PCB layout changes.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both EV35-3.0-02-10M and RD5122-6-9M6 are ROHS3 compliant, whereas the original ELF-22V030A is RoHS non-compliant.

Q: Does mounting orientation affect electrical performance?

A: Mounting orientation (vertical vs. horizontal) does not affect electrical performance but requires PCB layout modification. RD5122-6-9M6 uses horizontal orientation, while EV35-3.0-02-10M maintains vertical orientation matching the original.

Q: What is the impact of lower DC resistance in substitute parts?

A: Lower DC resistance (72mOhm for EV35-3.0-02-10M, 52.55mOhm for RD5122-6-9M6 vs. 85mOhm original) reduces power dissipation and heat generation, improving efficiency in power line filtering applications.

Q: Can RD5122-6-9M6 be used in applications designed for 3A operation?

A: Yes. RD5122-6-9M6 is rated for 6A maximum current, making it suitable for 3A applications. The higher rating provides operational margin and improved thermal performance.
