ELF-15N006A Common Mode Choke Equivalent & Substitute Parts

Part Overview

The ELF-15N006A is a 2-line common mode choke manufactured by Panasonic Electronic Components, rated for 600mA maximum current with a typical DC resistance of 933mOhm. This through-hole component is designed for power line filtering applications in electronic equipment. The part is currently obsolete, making identification of functionally equivalent substitutes essential for ongoing maintenance, repair, and new design implementations where legacy component compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELF-15N006A is determined by the following core parameters:

• Number of Lines: Must be 2-line configuration
• Current Rating (Max): Must support minimum 600mA
• Mounting Type: Must be through-hole
• Package / Case: Must be vertical, 4 PC pin configuration
• DC Resistance (DCR): Acceptable range based on application requirements

The two substitute parts listed below meet these core electrical and mechanical compatibility criteria. Both maintain the 2-line, 600mA, through-hole vertical pin configuration required for direct functional replacement in the ELF-15N006A application space.

Engineering Selection Recommendations

B82732R2601B030 (EPCOS - TDK Electronics)

This substitute maintains full electrical compatibility with the ELF-15N006A across all core parameters: 2-line configuration, 600mA current rating, through-hole mounting, and vertical 4-pin package. The part is currently in active production status with ROHS3 compliance and multiple approval agencies (ENEC, UR, VDE). DC resistance is 1.4Ohm typical, representing a 0.467Ohm increase from the original specification. Operating temperature range extends to -40°C ~ 125°C with 250V AC voltage rating specified. Packaging is provided in tray format.

SS11VL-06180 (KEMET)

This substitute also satisfies all core compatibility requirements: 2-line configuration, 600mA current rating, through-hole mounting, and vertical 4-pin package. The part is active in production with ROHS3 compliance. DC resistance is 1.3Ohm typical, representing a 0.367Ohm increase from the original specification. Operating temperature range is -25°C ~ 120°C with 250V AC voltage rating specified. Packaging is provided in bulk format. Physical dimensions are slightly more compact than the EPCOS alternative.

Both substitutes are suitable for applications where the ELF-15N006A is no longer available. Selection between them should be based on specific application requirements regarding operating temperature range, physical space constraints, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can the B82732R2601B030 or SS11VL-06180 be used as direct replacements for the ELF-15N006A?

A: Both parts meet the core electrical and mechanical compatibility criteria: 2-line configuration, 600mA current rating, through-hole mounting, and vertical 4-pin package. However, the increased DC resistance (1.4Ohm and 1.3Ohm respectively, compared to 933mOhm) must be evaluated against your specific application requirements. Physical dimensions differ slightly, requiring verification of PCB layout compatibility.

Q: What is the significance of the DC resistance difference?

A: The ELF-15N006A has a typical DC resistance of 933mOhm, while the B82732R2601B030 measures 1.4Ohm and the SS11VL-06180 measures 1.3Ohm. This represents an increase of approximately 0.37-0.47Ohm. In power line filtering applications, higher DC resistance results in increased power dissipation and heat generation at rated current. Application-specific thermal and performance analysis is required to determine acceptability.

Q: Are there physical space considerations when substituting these parts?

A: Yes. The ELF-15N006A measures 0.591" L x 0.894" W x 0.886" H. The B82732R2601B030 is larger at 0.945" L x 0.650" W x 0.925" H, while the SS11VL-06180 is more compact at 0.866" L x 0.571" W x 0.768" H. PCB layout verification is necessary to confirm fit within the available mounting space.

Q: What is the difference in RoHS compliance status?

A: The ELF-15N006A is RoHS non-compliant. Both substitute parts (B82732R2601B030 and SS11VL-06180) are ROHS3 compliant. If your application or regulatory environment requires RoHS compliance, either substitute is acceptable. If legacy non-compliant components are required, the ELF-15N006A must be sourced from existing inventory.

Q: How do the operating temperature ranges compare?

A: The ELF-15N006A does not specify an operating temperature range. The B82732R2601B030 operates from -40°C to 125°C, providing the widest range. The SS11VL-06180 operates from -25°C to 120°C. Selection should be based on your application's thermal environment requirements.

Q: What packaging formats are available for these substitutes?

A: The B82732R2601B030 is supplied in tray packaging, while the SS11VL-06180 is supplied in bulk packaging. Packaging format may influence handling, storage, and integration into your assembly process.
