Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELC-09D6R8F is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 6.8 µH (±20% tolerance acceptable)
• Mounting type: Through-hole configuration
• Package form: Radial, vertical cylinder orientation
• Shielding classification: Unshielded

Secondary Compatibility Factors:

• Current rating must equal or exceed 2.8 A
• DC resistance must not significantly exceed 21mOhm (affects thermal performance and circuit losses)
• RoHS3 compliance required for regulatory alignment

The Würth Elektronik 744772068 qualifies as a direct substitute based on matching inductance, mounting type, package configuration, and shielding characteristics. The substitute demonstrates improved electrical performance with higher current rating (3.8 A) and active product status.

Engineering Selection Recommendations

The Würth Elektronik 744772068 is the qualified substitute for the obsolete ELC-09D6R8F based on the following engineering criteria:

Compliance & Status:

• Both components maintain ROHS3 compliance, ensuring regulatory alignment for current manufacturing standards
• The substitute is active product status, providing long-term availability and supply chain stability

Electrical Compatibility:

• Inductance values are identical at 6.8 µH with matching ±20% tolerance
• Current rating of 3.8 A exceeds the original 2.8 A requirement, providing design margin
• DC resistance of 25mOhm maximum is within acceptable range for equivalent circuit performance

Physical & Mechanical Compatibility:

• Through-hole mounting type and radial vertical cylinder package form are identical
• Unshielded configuration matches the original design
• Physical dimensions are comparable for PCB layout compatibility

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 744772068 be used as a direct replacement for the ELC-09D6R8F?

A: Yes. Both components share identical inductance (6.8 µH), tolerance (±20%), shielding (unshielded), mounting type (through-hole), and package configuration (radial vertical cylinder). The substitute meets or exceeds all critical electrical parameters.

Q: What is the difference in DC resistance between the two parts?

A: The ELC-09D6R8F has 21mOhm DCR, while the 744772068 has 25mOhm maximum. This 4mOhm difference results in minimal additional power dissipation and is acceptable for equivalent circuit operation.

Q: Does the higher current rating of the substitute affect compatibility?

A: No. The 744772068 is rated for 3.8 A compared to the original 2.8 A. Higher current rating provides additional design margin and does not compromise circuit function when used in applications requiring 2.8 A or less.

Q: Are there physical dimension differences that affect PCB layout?

A: The substitute has slightly different dimensions (0.307" diameter vs. 0.374" diameter, and 0.394" height vs. 0.350" height). PCB footprint verification is required to confirm mechanical fit in the original layout.

Q: What is the advantage of selecting the active substitute over the obsolete original?

A: The Würth Elektronik 744772068 is active product status, ensuring continued availability, supply chain support, and manufacturing consistency. The obsolete ELC-09D6R8F faces procurement risk and potential discontinuation of inventory.
