ELF-15N007A Common Mode Choke Equivalent & Substitute Parts

Part Overview

The Panasonic ELF-15N007A is a 2-line common mode choke (CMC) designed for through-hole mounting with a 700mA current rating and 762mOhm typical DC resistance. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement.

Common mode chokes are essential filtering components in power line applications, providing electromagnetic interference (EMI) suppression across two conductors. The obsolete status of the ELF-15N007A requires identification of active alternative components that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELF-15N007A is determined by the following critical parameters:

• Number of Lines: Must be 2-line configuration
• Current Rating: Must support minimum 700mA
• Mounting Type: Must be through-hole
• Package Configuration: Must be vertical, 4-pin package
• DC Resistance: Should be within acceptable range for the application (762mOhm baseline)

All three substitute parts meet the core electrical and mechanical requirements. However, differences in inductance values, DC resistance, and compliance certifications create distinct application scenarios.

Parameter Comparison

Engineering Selection Recommendations

B82732R2701B030 (EPCOS - TDK Electronics)

This substitute maintains the 700mA current rating and provides the closest electrical match to the ELF-15N007A. It is ROHS3 compliant and carries active product status with established certifications (ENEC, UR, VDE). The increased DC resistance (1.1Ohm vs. 762mOhm) and higher inductance (39 mH @ 10 kHz) may require thermal and EMI performance validation in the target application. Dimensions are slightly larger (24.00mm x 16.50mm), requiring PCB layout verification.

SS11VL-07120 (KEMET)

This substitute offers the smallest footprint (22.00mm x 14.50mm) and lowest height (19.50mm), making it suitable for space-constrained applications. The 700mA current rating and 900mOhm DC resistance provide comparable electrical performance. ROHS3 compliance and active product status support modern design requirements. The 12 mH inductance @ 1 kHz differs from the original specification and requires application-specific validation.

EV28-2.0-02-11M (Schaffner EMC Inc.)

This substitute supports the highest current rating (2A), providing design margin for applications requiring higher current capacity. ROHS3 compliance is confirmed. However, the significantly larger footprint (29.20mm x 21.00mm) and height (35.70mm) may present PCB layout constraints. The 162mOhm DC resistance is the lowest among substitutes, reducing power dissipation. The 11 mH inductance @ 400 Hz differs from the original specification.

All three substitutes are active products with modern compliance certifications, contrasting with the obsolete status of the ELF-15N007A.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the ELF-15N007A with any of these substitutes without circuit modification?

A: All three substitutes maintain the 2-line configuration, through-hole mounting, and vertical 4-pin package. However, differences in inductance values, DC resistance, and physical dimensions require validation against your specific circuit requirements and PCB layout constraints.

Q: What is the primary reason for substitution?

A: The ELF-15N007A is classified as obsolete. The three active substitute parts ensure long-term component availability and support modern RoHS3 compliance requirements.

Q: How do the DC resistance values affect my application?

A: DC resistance directly impacts power dissipation and thermal performance. The ELF-15N007A baseline is 762mOhm. The B82732R2701B030 (1.1Ohm) will generate more heat, while the EV28-2.0-02-11M (162mOhm) will generate less. The SS11VL-07120 (900mOhm) is closest to the original specification.

Q: Are there physical size constraints I should consider?

A: Yes. The ELF-15N007A measures 15.00mm x 22.70mm with 22.50mm height. The SS11VL-07120 is the most compact substitute (22.00mm x 14.50mm x 19.50mm). The EV28-2.0-02-11M is the largest (29.20mm x 21.00mm x 35.70mm). Verify PCB layout compatibility before selection.

Q: Which substitute has the best compliance certifications?

A: The B82732R2701B030 carries the most comprehensive certifications (ENEC, UR, VDE) in addition to ROHS3 compliance. All three substitutes are ROHS3 compliant and support modern design standards.

Q: What is the current rating difference between substitutes?

A: The ELF-15N007A and B82732R2701B030 and SS11VL-07120 are rated for 700mA. The EV28-2.0-02-11M supports 2A, providing additional current capacity margin for higher-power applications.
