DKIL-0246-2001 Equivalent & Substitute Parts

Part Overview

The DKIL-0246-2001 is a 2-line common mode choke (CMC) designed for through-hole mounting with a 20A current rating and 6mOhm maximum DC resistance. Manufactured by SCHURTER Inc., this component is classified as obsolete, necessitating identification of active equivalent parts for continued system design and procurement. The DKIL series represents legacy filtering technology in power line applications, and active alternatives ensure design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

The DKIH-3242-20D5 qualifies as a functional substitute for the DKIL-0246-2001 based on the following critical parameters:

• Number of Lines: Both parts feature 2-line configuration for common mode filtering
• Current Rating: Both rated at 20A maximum current
• Mounting Type: Both utilize through-hole mounting technology
• Manufacturer: Both manufactured by SCHURTER Inc., ensuring design consistency
• Product Status: The DKIH-3242-20D5 is active, providing continued availability

The DKIH-3242-20D5 represents an improved design iteration with reduced DC resistance (2.5mOhm versus 6mOhm), enhanced thermal operating range (-40°C to 100°C), and expanded regulatory approvals (cURus, ENEC versus UR only).

Parameter Comparison

Engineering Selection Recommendations

The DKIH-3242-20D5 is the designated active substitute for the obsolete DKIL-0246-2001. Selection of the DKIH-3242-20D5 is supported by:

• Active product status ensuring long-term availability and supply chain continuity
• Identical 20A current rating and 2-line configuration maintaining functional compatibility
• Through-hole mounting compatibility with existing PCB designs
• Enhanced regulatory approvals (cURus, ENEC) providing broader market compliance
• Improved DC resistance specification (2.5mOhm) reducing power dissipation
• Extended low-temperature operating range (-40°C) for broader environmental applications
• ROHS3 compliance alignment with current manufacturing standards

Applications requiring the original voltage ratings (760V DC / 540V AC) of the DKIL-0246-2001 must evaluate the reduced voltage specifications of the DKIH-3242-20D5 (425V DC / 300V AC) for circuit compatibility.

Frequently Asked Questions (FAQ)

Q: Can the DKIH-3242-20D5 directly replace the DKIL-0246-2001 in existing designs?

A: The DKIH-3242-20D5 provides functional substitution for 20A, 2-line common mode choke applications with through-hole mounting. Voltage rating compatibility must be verified; the substitute operates at 425V DC / 300V AC versus the original 760V DC / 540V AC specifications.

Q: What are the key differences between these parts?

A: The primary differences are product status (active versus obsolete), DC resistance (2.5mOhm versus 6mOhm), voltage ratings (425V/300V versus 760V/540V), operating temperature range (-40°C to 100°C versus -25°C to 100°C), and regulatory approvals (cURus, ENEC versus UR).

Q: Are there packaging differences between the DKIL-0246-2001 and DKIH-3242-20D5?

A: The DKIL-0246-2001 uses radial packaging with 50.00mm x 50.00mm dimensions. The DKIH-3242-20D5 uses horizontal, 4-pin configuration with 43.00mm diameter and 26.00mm maximum height. PCB layout modifications may be required.

Q: Does the reduced DC resistance of the DKIH-3242-20D5 affect circuit performance?

A: The 2.5mOhm DC resistance of the DKIH-3242-20D5 is lower than the 6mOhm specification of the DKIL-0246-2001, resulting in reduced power dissipation and improved thermal performance in the substitute part.

Q: Are both parts RoHS compliant?

A: Yes, both the DKIL-0246-2001 and DKIH-3242-20D5 are ROHS3 compliant and REACH unaffected.
