ELC-09D182F Equivalent & Substitute Parts

Part Overview

The ELC-09D182F is a 1.8 mH unshielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 190 mA with a DC resistance of 3.8 Ohm. This through-hole radial component operates at a test frequency of 10 kHz and is packaged in a vertical cylinder configuration with a 0.374" diameter and 0.350" maximum seated height.

The ELC-09D182F is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity and ensure component availability for new production runs, repairs, and system upgrades where this inductor specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELC-09D182F is determined by the following critical parameters:

Inductance Value: 1.8 mH (±10% tolerance band)

Current Rating: Substitute parts must support a minimum of 190 mA. Parts with higher current ratings are acceptable as they provide additional design margin.

DC Resistance: Substitute parts must maintain DCR at or below 3.8 Ohm to preserve circuit performance characteristics.

Mounting Type: Through-hole configuration is mandatory for mechanical compatibility.

Package / Case: Radial, vertical cylinder configuration required for PCB layout compatibility.

Shielding: Unshielded construction maintains electromagnetic compatibility with the original design.

Compliance: RoHS3 compliance is required for regulatory alignment.

The Würth Elektronik 768772182 meets all substitution criteria with enhanced specifications in current rating (350 mA vs. 190 mA) and improved DC resistance (3.3 Ohm vs. 3.8 Ohm), while maintaining identical inductance value and compatible physical form factor.

Parameter Comparison

Engineering Selection Recommendations

The Würth Elektronik 768772182 is a qualified substitute for the obsolete ELC-09D182F based on the following factors:

Product Status: The 768772182 maintains active production status, ensuring long-term component availability and supply chain stability compared to the obsolete ELC-09D182F.

Regulatory Compliance: Both components are ROHS3 compliant, maintaining regulatory alignment for applications subject to hazardous substance restrictions.

Electrical Performance: The 768772182 delivers superior electrical characteristics with a lower DC resistance (3.3 Ohm vs. 3.8 Ohm) and higher current rating (350 mA vs. 190 mA), providing enhanced thermal performance and design margin without compromising the specified 1.8 mH inductance value.

Physical Compatibility: While the 768772182 exhibits a smaller diameter (0.307" vs. 0.374") and slightly greater height (0.394" vs. 0.350"), both components maintain radial, vertical cylinder configurations suitable for through-hole PCB mounting. PCB layout verification is required to confirm dimensional compatibility in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 768772182 be used as a direct replacement for the ELC-09D182F?

A: The 768772182 is electrically compatible as a substitute. Both components share identical inductance values (1.8 mH) and tolerance specifications (±10%). The 768772182 provides superior current handling (350 mA vs. 190 mA) and lower DC resistance (3.3 Ohm vs. 3.8 Ohm). Physical dimensions differ slightly; PCB layout verification is necessary to confirm fit within the available mounting space.

Q: What are the key differences between these two inductors?

A: The primary differences are product status (768772182 is active; ELC-09D182F is obsolete), core material (768772182 uses ferrite drum core; ELC-09D182F uses standard wirewound), current rating (768772182 rated 350 mA; ELC-09D182F rated 190 mA), and physical dimensions (768772182 is smaller in diameter but taller). Electrical performance is equivalent at the specified 1.8 mH inductance value.

Q: Are there any compliance or certification concerns with substitution?

A: Both components are ROHS3 compliant. The 768772182 carries REACH Unaffected status. No compliance barriers exist for substitution in applications requiring these certifications.

Q: What should be verified before implementing the 768772182 as a substitute?

A: Verify PCB layout compatibility given the dimensional differences (smaller diameter, greater height). Confirm that the higher current rating and lower DC resistance do not introduce unintended circuit behavior. Validate that the ferrite drum core construction of the 768772182 is compatible with the application's electromagnetic environment.

Q: Is the 768772182 available in the same packaging format?

A: The 768772182 is supplied in tray packaging, whereas the ELC-09D182F packaging format is not specified in the available data. Both components use identical through-hole radial, vertical cylinder mounting configurations. Packaging format does not affect electrical or mechanical compatibility.
