ELF-16M060A Common Mode Choke Equivalent & Substitute Parts

Part Overview

The ELF-16M060A is a 2-line common mode choke (CMC) designed for through-hole mounting with a 600mA current rating and 800mOhm typical DC resistance. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. The through-hole configuration and vertical 4-pin package define its mechanical footprint and installation requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELF-16M060A is determined by the following critical parameters:

• Number of Lines: Must be 2-line configuration
• Current Rating: Must support minimum 600mA
• Mounting Type: Must be through-hole
• Package Configuration: Must be vertical, 4-pin package
• Physical Dimensions: Height must not exceed 0.807" (20.50mm) to ensure PCB clearance compatibility
• DC Resistance: Substitute must maintain comparable DCR performance within acceptable operating margins

The B82731M2601A030 from EPCOS - TDK Electronics meets these substitution criteria while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The B82731M2601A030 is the designated substitute for the obsolete ELF-16M060A based on the following factors:

Product Status: The substitute is active and currently manufactured, ensuring long-term availability and supply chain stability compared to the obsolete main part.

Compliance & Certifications: The B82731M2601A030 holds ROHS3 compliance and multiple approval agencies (ENEC, UR, VDE), providing enhanced regulatory alignment for modern applications. The main part is RoHS non-compliant.

Mechanical Compatibility: Both parts share identical mounting type (through-hole), package configuration (vertical, 4-pin), and maximum height (0.807"), ensuring direct PCB layout compatibility without redesign.

Electrical Parameters: Both parts maintain 600mA current rating and 2-line configuration. The substitute exhibits higher DC resistance (1.5Ohm vs. 800mOhm), which must be evaluated within the specific circuit application to confirm acceptable performance margins.

Environmental Specifications: The substitute provides defined operating temperature range (-40°C ~ 125°C) and AC voltage rating (250V), offering clearer performance boundaries for system design.

Frequently Asked Questions (FAQ)

Q: Can the B82731M2601A030 be used as a direct replacement for the ELF-16M060A?

A: Yes, for through-hole PCB applications. Both parts share identical mounting type, package configuration, and maximum height. However, the higher DC resistance of the substitute (1.5Ohm vs. 800mOhm) must be verified against circuit requirements to ensure acceptable voltage drop and thermal performance.

Q: What is the primary reason for substitution?

A: The ELF-16M060A is obsolete. The B82731M2601A030 is an active product with current manufacturing support, ensuring component availability and supply chain continuity.

Q: Are there compliance differences between the two parts?

A: Yes. The substitute is ROHS3 compliant with certifications from ENEC, UR, and VDE, while the main part is RoHS non-compliant. This is significant for applications subject to regulatory requirements.

Q: Will the substitute fit the existing PCB layout?

A: Yes. Both parts have identical maximum height (0.807" / 20.50mm), vertical 4-pin package configuration, and through-hole mounting type. No PCB redesign is required for mechanical fit.

Q: How does the higher DC resistance of the substitute affect circuit performance?

A: The B82731M2601A030 exhibits 1.5Ohm typical DCR compared to 800mOhm for the main part. This difference increases voltage drop and power dissipation. Circuit analysis is required to confirm this parameter change is acceptable for the specific application.

Q: What packaging is available for the substitute?

A: The B82731M2601A030 is supplied in tray packaging, compared to the main part's unspecified packaging. Confirm packaging requirements for your procurement and assembly processes.
