ELC-09D560F Equivalent & Substitute Parts

Part Overview

The ELC-09D560F is a 56 µH unshielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 1.1 A with a DC resistance of 130mOhm. This through-hole radial component operates in the 09D series and is classified as obsolete. Due to its obsolete status, identifying equivalent substitute parts with compatible electrical and mechanical specifications is essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELC-09D560F is determined by the following critical parameters:

• Inductance Value: 56 µH (exact match required)
• Tolerance: ±10% (matching tolerance ensures circuit performance)
• Current Rating: Minimum 1.1 A (substitute must support or exceed the original rating)
• DC Resistance: Maximum 130mOhm (lower or equal DCR is acceptable; higher values may impact circuit efficiency)
• Shielding: Unshielded (maintains electromagnetic compatibility with original design)
• Mounting Type: Through Hole (ensures PCB compatibility)
• Package / Case: Radial, Vertical Cylinder (mechanical fit requirement)

The RL875-560K-RC from Bourns Inc. meets these substitution criteria with compatible electrical specifications and active product status.

Parameter Comparison

Engineering Selection Recommendations

The RL875-560K-RC qualifies as a functional substitute for the obsolete ELC-09D560F based on the following factors:

• Electrical Compatibility: Both components share identical inductance (56 µH) and tolerance (±10%). The Bourns substitute provides higher current rating (1.2 A vs. 1.1 A), exceeding the original specification.
• DC Resistance Consideration: The RL875-560K-RC exhibits 180mOhm maximum DCR compared to the original 130mOhm. This 50mOhm increase may introduce additional power dissipation in current-limited applications and should be evaluated against circuit thermal and efficiency requirements.
• Physical Dimensions: The substitute is physically smaller (0.307" diameter, 0.295" height) compared to the original (0.374" diameter, 0.350" height). PCB layout verification is required to confirm fit within existing component footprints.
• Compliance & Availability: The RL875-560K-RC maintains ROHS3 compliance and carries active product status, ensuring long-term availability and supply chain stability compared to the obsolete ELC-09D560F.

Frequently Asked Questions (FAQ)

Q: Can the RL875-560K-RC directly replace the ELC-09D560F without circuit modifications?

A: Electrical substitution is feasible due to matching inductance and tolerance values. However, the increased DC resistance (180mOhm vs. 130mOhm) may affect circuit performance in applications sensitive to inductor losses. Physical dimensions are smaller, requiring PCB layout verification for mechanical fit.

Q: What is the impact of the higher DC resistance in the substitute part?

A: The 50mOhm increase in DCR will result in additional resistive losses proportional to the square of the operating current. In a 1.1 A application, this translates to approximately 60 mW additional power dissipation. Thermal and efficiency analysis is recommended for power-critical designs.

Q: Are both parts RoHS compliant?

A: Yes, both the ELC-09D560F and RL875-560K-RC are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing.

Q: Why is the substitute part smaller in physical size?

A: The RL875-560K-RC uses a drum core ferrite construction, which provides higher inductance density compared to the wirewound design of the ELC-09D560F. This allows equivalent inductance in a more compact form factor.

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

A: The RL875-560K-RC is specified with a self-resonant frequency of 10 MHz and Q factor of 26 @ 2.52 MHz, indicating suitability for applications operating below these frequency thresholds. The original ELC-09D560F does not provide frequency specifications for direct comparison.
