ELC-09D182DF Equivalent & Substitute Parts

Part Overview

The ELC-09D182DF 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 is designed for applications requiring fixed inductance in compact form factors. The part is currently obsolete, making equivalent substitutes necessary for ongoing production, maintenance, and design updates.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the ELC-09D182DF is determined by the following critical parameters:

• Inductance value: 1.8 mH (±10% tolerance acceptable)
• Current rating: minimum 190 mA
• DC resistance: within acceptable operating limits
• Mounting type: Through Hole
• Package configuration: Radial, Vertical Cylinder
• Shielding: Unshielded
• Compliance: ROHS3 Compliant

The Würth Elektronik 768772182 qualifies as a direct substitute based on matching inductance, exceeding current rating capability, maintaining unshielded configuration, and meeting through-hole radial mounting requirements. Both parts are ROHS3 compliant and suitable for equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The Würth Elektronik 768772182 is the qualified substitute for the obsolete ELC-09D182DF. Selection is based on:

• Both parts maintain identical inductance value and tolerance specification
• The substitute provides superior current rating (350 mA vs. 190 mA), offering design margin
• DC resistance of the substitute (3.3 Ohm Max) is lower, reducing power dissipation
• Both components are ROHS3 compliant, meeting regulatory requirements
• The substitute is active in production, ensuring long-term availability
• Through-hole radial mounting configuration is preserved for PCB compatibility
• Unshielded design maintains electromagnetic characteristics of the original

Physical dimensions differ slightly; the substitute is smaller in diameter (7.80mm vs. 9.50mm) but slightly taller (10.00mm vs. 8.90mm). PCB layout verification is required to confirm fit within existing footprints.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 768772182 be used as a direct replacement for the ELC-09D182DF?

A: Yes. Both parts share the same inductance value, tolerance, unshielded configuration, and through-hole radial mounting. The substitute exceeds the current rating requirement and provides lower DC resistance.

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

A: The Würth Elektronik substitute has a smaller diameter (7.80mm vs. 9.50mm) but is slightly taller (10.00mm vs. 8.90mm). Verify PCB footprint clearance before implementation.

Q: Are both parts RoHS compliant?

A: Yes. Both the ELC-09D182DF and 768772182 are ROHS3 compliant.

Q: Why is the substitute rated for higher current?

A: The Würth Elektronik part uses a drum core ferrite design with different winding geometry, allowing higher current capacity (350 mA vs. 190 mA) while maintaining the same inductance value.

Q: What is the product status difference?

A: The original ELC-09D182DF is obsolete. The Würth Elektronik 768772182 is active in production, ensuring availability for new designs and ongoing supply.

Q: Are there packaging differences?

A: The original is supplied in standard packaging. The substitute is supplied in trays. Verify packaging requirements for your assembly process.
