ELF-20N010A Common Mode Choke Equivalent & Substitute Parts

Part Overview

The ELF-20N010A is a 2-line common mode choke manufactured by Panasonic Electronic Components, designed for through-hole mounting applications requiring 1A current handling capability. This component features a typical DC resistance of 500mOhm and is housed in a vertical 4-pin package with dimensions of 20.00mm × 32.00mm × 30.00mm (max height).

The ELF-20N010A is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or repair requirements for systems utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELF-20N010A is determined by the following critical parameters:

• Number of Lines: Must be 2-line configuration to maintain common mode filtering functionality
• Mounting Type: Must be through-hole to ensure PCB compatibility
• Package Configuration: Must be vertical 4-pin package for mechanical fit
• Current Rating: Substitute must support minimum 1A operation
• DC Resistance: Substitute DCR must not exceed the application's tolerance requirements

The SS26V-080350 manufactured by KEMET qualifies as a substitute based on these criteria. It maintains the 2-line configuration, through-hole mounting, vertical 4-pin package, and supports 800mA current rating with 1Ohm DCR. While the current rating is slightly lower (800mA vs. 1A), the part remains functionally compatible for applications operating within the 800mA threshold.

Parameter Comparison

Engineering Selection Recommendations

The SS26V-080350 is an active product with current manufacturing support, making it suitable for applications requiring long-term component availability. Both parts share identical ECCN classification (EAR99), ensuring consistent export compliance handling.

The primary consideration for selection is current rating: the ELF-20N010A supports 1A, while the SS26V-080350 supports 800mA. Applications operating at or below 800mA can utilize the KEMET substitute without derating. Applications requiring the full 1A capability must verify alternative sources or confirm that the 800mA rating meets system requirements.

The SS26V-080350 provides specified AC voltage rating (250V) and operating temperature range (-25°C ~ 120°C), parameters not specified for the ELF-20N010A. These specifications should be cross-referenced with original design requirements to confirm compatibility.

Frequently Asked Questions (FAQ)

Q: Can the SS26V-080350 directly replace the ELF-20N010A in all applications?

A: Direct replacement is possible only for applications operating at or below 800mA. The ELF-20N010A supports 1A; the SS26V-080350 supports 800mA. Verify your application's actual current draw before substitution.

Q: Are the physical dimensions compatible?

A: Both parts use vertical 4-pin through-hole packages with similar heights (30.00mm vs. 30.50mm max). However, footprint dimensions differ: ELF-20N010A is 20.00mm × 32.00mm; SS26V-080350 is 26.00mm × 20.50mm. PCB layout verification is required to confirm mechanical fit.

Q: What is the difference in DC resistance between these parts?

A: The ELF-20N010A has 500mOhm typical DCR, while the SS26V-080350 has 1Ohm DCR. The substitute exhibits higher resistance, which may affect power dissipation and filtering characteristics. Thermal and performance analysis is necessary for critical applications.

Q: Are both parts RoHS compliant?

A: The ELF-20N010A compliance status is not specified in available data. The SS26V-080350 is ROHS3 compliant and REACH unaffected, providing documented environmental compliance for new designs.

Q: What are the voltage and temperature specifications for the ELF-20N010A?

A: Voltage rating (DC and AC) and operating temperature range are not specified for the ELF-20N010A. The SS26V-080350 specifies 250V AC rating and -25°C ~ 120°C operating range. Original design documentation should be consulted to confirm compatibility with these parameters.
