Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELC-09D561DF is determined by the following critical parameters:

Inductance Value: 560 µH with ±10% tolerance is the primary electrical specification. Substitute parts must maintain this inductance value within the specified tolerance band.

Current Rating: The main part supports 360 mA. Substitute parts must equal or exceed this current rating to ensure safe operation without thermal stress or saturation effects.

DC Resistance: The 1.1Ohm specification defines power dissipation characteristics. Substitute parts with equal or lower DCR are acceptable, as they reduce resistive losses.

Mounting and Package: Through-hole radial vertical cylinder configuration is required for mechanical compatibility with existing PCB layouts.

Regulatory Compliance: ROHS3 compliance is mandatory for environmental and regulatory adherence.

The Würth Elektronik 744772561 meets these substitution criteria with matching inductance, superior current rating (400 mA), lower DCR (1Ohm Max), and equivalent package configuration.

Engineering Selection Recommendations

The Würth Elektronik 744772561 is the qualified substitute for the obsolete ELC-09D561DF. Selection is based on the following engineering criteria:

Electrical Equivalence: Both components specify 560 µH inductance with ±10% tolerance. The substitute provides 400 mA current rating, exceeding the original 360 mA specification, ensuring adequate headroom for circuit operation.

Resistance Profile: The substitute's 1Ohm Max DCR is lower than the original 1.1Ohm specification, resulting in reduced power dissipation and improved efficiency.

Regulatory Compliance: Both components maintain ROHS3 compliance, satisfying environmental and procurement requirements.

Product Availability: The substitute is classified as active with confirmed inventory (1809 Pcs), ensuring long-term procurement viability compared to the obsolete original component.

Physical Compatibility: Radial vertical cylinder through-hole configuration is maintained across both components, supporting direct PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 744772561 directly replace the ELC-09D561DF in existing designs?

A: Yes. Both components share identical inductance (560 µH), tolerance (±10%), unshielded configuration, and through-hole radial vertical cylinder package. The substitute's superior current rating (400 mA vs. 360 mA) and lower DCR (1Ohm Max vs. 1.1Ohm) provide enhanced performance margins.

Q: What is the primary reason for substitution?

A: The ELC-09D561DF is classified as obsolete. The 744772561 is an active component with confirmed inventory availability, ensuring design continuity and long-term supply chain reliability.

Q: Are there dimensional differences between these components?

A: Minor dimensional variations exist. The ELC-09D561DF measures 9.50mm diameter by 8.90mm height, while the 744772561 measures 7.80mm diameter by 10.00mm height. Both maintain radial vertical cylinder configuration suitable for through-hole PCB mounting. PCB layout verification is recommended for space-constrained applications.

Q: Do both components meet the same regulatory standards?

A: Yes. Both the ELC-09D561DF and 744772561 are ROHS3 compliant. The substitute additionally carries REACH Unaffected status, providing expanded regulatory coverage.

Q: What is the inductance test frequency for each component?

A: The ELC-09D561DF is tested at 10 kHz, while the 744772561 is tested at 1 kHz. Both maintain the specified 560 µH inductance within their respective test conditions and ±10% tolerance band.
