ELC-06D2R2E Equivalent & Substitute Parts

Part Overview

The ELC-06D2R2E is a 2.2 µH unshielded through-hole inductor manufactured by Panasonic Electronic Components, rated for 3.4 A continuous current with 26mOhm DC resistance. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. Substitute parts must maintain the same inductance value, tolerance, mounting type, and core electrical characteristics to ensure circuit performance equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELC-06D2R2E is determined by the following criteria:

Primary Matching Parameters:

• Inductance value: 2.2 µH (exact match required)
• Tolerance: ±20% (standard tolerance match)
• Mounting type: Through Hole (mechanical compatibility)
• Package configuration: Radial, Vertical Cylinder (footprint compatibility)
• Shielding: Unshielded (electromagnetic environment match)

Secondary Compatibility Parameters:

• Current rating: Must equal or exceed 3.4 A
• DC resistance: Should be comparable to 26mOhm (within engineering tolerance for circuit performance)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

Both identified substitute parts meet the primary matching parameters. Variations in current rating and DC resistance are acceptable provided the substitute part can support the circuit's maximum current demand without exceeding thermal or saturation limits.

Parameter Comparison

Engineering Selection Recommendations

744772022 (Würth Elektronik WE-TI Series): This substitute provides superior electrical performance with 6.7 A current rating and reduced DC resistance of 10mOhm maximum, offering design margin above the original 3.4 A specification. The part is active in production with ROHS3 compliance and extended operating temperature range (-40°C to 125°C). Physical dimensions are slightly larger (0.307" diameter vs. 0.264"), requiring PCB layout verification for footprint compatibility.

RCH664NP-2R2M (Sumida RCH-664 Series): This substitute maintains electrical characteristics closely aligned with the original part, with 3.2 A current rating and 25.5mOhm maximum DC resistance. The part is active in production with ROHS3 compliance and operating temperature range of -40°C to 100°C. Physical dimensions are smaller (0.236" diameter, 0.256" height), providing improved PCB space efficiency. This option is recommended when physical footprint constraints or thermal considerations favor the original compact form factor.

Both substitutes are ROHS3 compliant and available in active production status, ensuring long-term supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the 744772022 be used as a direct replacement for the ELC-06D2R2E?

A: Yes, the 744772022 meets all primary substitution criteria: identical 2.2 µH inductance, ±20% tolerance, through-hole mounting, and unshielded configuration. The higher current rating (6.7 A vs. 3.4 A) and lower DC resistance (10mOhm vs. 26mOhm) provide additional design margin. Physical dimensions differ slightly; verify PCB layout compatibility before implementation.

Q: Is the RCH664NP-2R2M suitable for applications requiring 3.4 A continuous current?

A: The RCH664NP-2R2M is rated for 3.2 A continuous current, which is 0.2 A below the original specification. This part is suitable only for applications where the actual circuit current demand does not exceed 3.2 A. For circuits requiring the full 3.4 A specification, the 744772022 is the recommended substitute.

Q: What are the physical footprint differences between these parts?

A: The ELC-06D2R2E measures 0.264" diameter × 0.394" height. The 744772022 measures 0.307" diameter × 0.394" height (larger diameter, same height). The RCH664NP-2R2M measures 0.236" diameter × 0.256" height (smaller overall). PCB layout must accommodate these dimensional variations.

Q: Are all three parts RoHS compliant?

A: Yes, the ELC-06D2R2E, 744772022, and RCH664NP-2R2M are all ROHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and assembly.

Q: What is the difference between the original part's obsolete status and the active status of the substitutes?

A: The ELC-06D2R2E is no longer manufactured by Panasonic. Both substitute parts are in active production, ensuring availability for new designs and ongoing production support. Active status provides supply chain continuity and access to current manufacturing batches.
