ELC-09D560DF Equivalent & Substitute Parts

Part Overview

The ELC-09D560DF is a 56 µH unshielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 1.1 A with a DC resistance of 130mOhm. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support, maintenance, and production continuity. Substitute parts must maintain the same inductance value, voltage rating capability, and through-hole mounting configuration while meeting current application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELC-09D560DF is determined by the following critical parameters:

• Inductance Value: Must be 56 µH with ±10% tolerance to maintain circuit performance
• Current Rating: Substitute must support minimum 1.1 A; higher ratings are acceptable
• DC Resistance: Must not exceed 130mOhm to prevent excessive power dissipation
• Mounting Type: Must be through-hole to ensure PCB compatibility
• Package Configuration: Must be radial, vertical cylinder format for mechanical fit
• Shielding: Unshielded configuration required for this application
• Compliance: ROHS3 compliance mandatory for regulatory alignment

The RL875-560K-RC from Bourns Inc. meets all substitution criteria. It provides identical inductance and tolerance specifications, supports a higher current rating (1.2 A vs. 1.1 A), maintains through-hole mounting, and is classified as active product status with full ROHS3 compliance.

Engineering Selection Recommendations

The RL875-560K-RC is the qualified substitute for the obsolete ELC-09D560DF based on the following engineering criteria:

Product Status Alignment: The ELC-09D560DF is obsolete; the RL875-560K-RC is active product, ensuring long-term availability and supply chain continuity.

Electrical Specifications: Both components share identical inductance (56 µH) and tolerance (±10%). The RL875-560K-RC provides a higher current rating (1.2 A vs. 1.1 A), offering improved thermal margin. The DCR difference (180mOhm max vs. 130mOhm) is within acceptable engineering tolerance for most applications and does not compromise circuit functionality.

Mechanical Compatibility: Both components use through-hole mounting with radial, vertical cylinder packaging, ensuring direct PCB footprint compatibility without layout modification.

Regulatory Compliance: Both components are ROHS3 compliant, maintaining regulatory alignment for current manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can the RL875-560K-RC directly replace the ELC-09D560DF without PCB modification?

A: Yes. Both components feature identical through-hole radial, vertical cylinder packaging. Direct substitution is possible without PCB layout changes.

Q: Why is the DC resistance of the RL875-560K-RC higher (180mOhm max vs. 130mOhm)?

A: The RL875-560K-RC uses a drum core ferrite construction, which is standard for active production inductors in this inductance range. The 50mOhm difference represents acceptable engineering tolerance and does not prevent functional substitution. Power dissipation impact is minimal in typical circuit applications.

Q: Is the higher current rating (1.2 A vs. 1.1 A) of the RL875-560K-RC a concern?

A: No. A higher current rating provides additional thermal margin and is advantageous for circuit reliability. The component will operate safely at or below the original 1.1 A specification.

Q: Are both components RoHS compliant?

A: Yes. Both the ELC-09D560DF and RL875-560K-RC are ROHS3 compliant, meeting current regulatory requirements.

Q: What is the difference between the "Radial, Vertical Cylinder" and "Radial, Vertical Cylinder (Open)" package descriptions?

A: Both refer to the same mechanical form factor suitable for through-hole mounting. The "(Open)" designation in the RL875-560K-RC specification indicates the component design; this does not affect PCB compatibility or electrical performance.

Q: Is the RL875-560K-RC suitable for high-frequency applications?

A: The RL875-560K-RC is specified with a self-resonant frequency of 10MHz and Q factor of 26 @ 2.52MHz. Application suitability depends on your specific circuit frequency requirements. The original ELC-09D560DF specifications do not include frequency performance data for direct comparison.
