ELC-08D2R2DF Equivalent & Substitute Parts

Part Overview

The ELC-08D2R2DF is a 2.2 µH unshielded inductor manufactured by Panasonic Electronic Components, rated for 7.2 A continuous current with 10mOhm DC resistance. This through-hole radial component is designed for applications requiring fixed inductance in compact form factors. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

The Würth Elektronik 7447471022 qualifies as a functional equivalent based on the following critical parameters:

Matching Parameters:

• Inductance: 2.2 µH (identical)
• Tolerance: ±20% (identical)
• Mounting Type: Through Hole (identical)
• Package Type: Radial, Vertical Cylinder (identical)
• Core Material: Ferrite (identical)
• RoHS3 Compliance: Both parts meet ROHS3 requirements

Enhanced Specifications:

• Current Rating: 8.2 A (exceeds 7.2 A requirement)
• DC Resistance: 8.8mOhm Max (lower than 10mOhm, improved performance)
• Saturation Current: 10A (specified, providing design margin)
• Shielding: Shielded (upgraded from unshielded)
• Operating Temperature: -40°C ~ 125°C (defined range)
• Product Status: Active (currently manufactured)

The substitute part maintains all critical electrical and mechanical compatibility while offering improved electrical characteristics and active production status.

Parameter Comparison

Engineering Selection Recommendations

The Würth Elektronik 7447471022 is the qualified substitute for the obsolete ELC-08D2R2DF based on the following factors:

Compliance & Availability:

• Both parts maintain ROHS3 compliance for regulated applications
• The substitute is in active production with confirmed inventory availability
• The original part is obsolete, eliminating long-term sourcing viability

Electrical Compatibility:

• Identical inductance and tolerance specifications ensure circuit performance equivalence
• Superior current rating (8.2 A vs. 7.2 A) provides additional design margin
• Lower DC resistance (8.8mOhm vs. 10mOhm) reduces power dissipation
• Shielded construction of the substitute offers improved EMI performance compared to the unshielded original

Mechanical Compatibility:

• Both parts use identical through-hole radial vertical cylinder packaging
• Dimensional differences are minor: substitute is 1.39mm larger in diameter and 1.50mm shorter in height
• PCB footprint compatibility is maintained for standard radial inductor layouts

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 7447471022 directly replace the ELC-08D2R2DF in existing designs?

A: Yes. Both parts share identical inductance (2.2 µH), tolerance (±20%), mounting type (through hole), and package configuration (radial vertical cylinder). The substitute meets or exceeds all critical electrical parameters of the original part.

Q: What are the dimensional differences between these parts?

A: The Würth Elektronik substitute is 0.039" (1.00mm) larger in diameter and 0.059" (1.50mm) shorter in height. For standard through-hole radial layouts with adequate PCB spacing, these differences do not affect compatibility. Verify clearance in confined mounting areas.

Q: Does the shielded construction of the substitute affect circuit behavior?

A: The shielded design of the Würth Elektronik part provides improved electromagnetic interference (EMI) rejection compared to the unshielded original. This is a performance enhancement with no negative impact on circuit function.

Q: Are both parts RoHS compliant?

A: Yes. Both the ELC-08D2R2DF and 7447471022 are ROHS3 compliant, meeting regulatory requirements for restricted substances in electrical and electronic equipment.

Q: Why is the original part obsolete?

A: The ELC-08D2R2DF is listed as obsolete by Panasonic Electronic Components. The Würth Elektronik 7447471022 remains in active production, ensuring long-term availability for new designs and production continuity.

Q: What is the saturation current specification?

A: The Würth Elektronik substitute specifies a saturation current (Isat) of 10A, indicating the current level at which inductance begins to degrade. The original part does not provide this specification. This additional parameter in the substitute provides design confidence for current margin calculations.
