ELC-09D5R6DF Equivalent & Substitute Parts

Part Overview

The ELC-09D5R6DF is a 5.6 µH unshielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 2.9 A continuous current with 19mOhm DC resistance. This through-hole radial component operates at 10 kHz inductance test frequency and is housed in a vertical cylinder package measuring 0.374" diameter by 0.350" height.

The product is currently obsolete, making equivalent substitutes necessary for ongoing design support and production continuity. Substitute parts must maintain the same inductance value, current rating compatibility, and through-hole radial mounting configuration to ensure functional equivalence in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELC-09D5R6DF is determined by the following critical parameters:

Inductance Value: Must be 5.6 µH to maintain circuit performance and frequency response characteristics.

Current Rating: Substitute must support minimum 2.9 A continuous current. Higher current ratings provide design margin and are acceptable.

DC Resistance (DCR): The original part specifies 19mOhm. Substitute parts with higher DCR values (such as 90mOhm maximum) introduce increased power dissipation and thermal effects. Selection depends on circuit thermal tolerance.

Mounting Configuration: Must be through-hole with radial, vertical cylinder package geometry to ensure mechanical compatibility with existing PCB layouts.

Shielding: Both main and substitute parts are unshielded, maintaining electromagnetic compatibility characteristics.

Type: Wirewound construction is maintained across substitutes to preserve inductance stability and current handling characteristics.

The B82144B2562K000 from EPCOS - TDK Electronics meets the core substitution criteria: identical 5.6 µH inductance, compatible 2.95 A current rating, through-hole radial mounting, and unshielded wirewound construction. However, the significantly higher DCR (90mOhm maximum versus 19mOhm) represents a material design change that must be evaluated for thermal and efficiency impact in the target application.

Parameter Comparison

Engineering Selection Recommendations

The B82144B2562K000 qualifies as a functional substitute based on matching inductance value, compatible current rating, and identical through-hole radial mounting configuration. Both parts maintain ROHS3 compliance and EAR99 export classification.

The substitute part offers tighter inductance tolerance (±10% versus ±20%), providing improved circuit performance predictability. The active product status of the B82144B2562K000 ensures long-term availability and supply chain continuity compared to the obsolete ELC-09D5R6DF.

Critical design consideration: The B82144B2562K000 exhibits significantly higher DC resistance (90mOhm maximum versus 19mOhm). This 4.7× increase in DCR will produce proportionally higher I²R power dissipation in the inductor. Thermal analysis of the target circuit is required to confirm acceptable operating temperature rise and component reliability under the application's current profile.

Physical dimensions differ: the substitute is smaller in diameter (0.256" versus 0.374") but taller (0.551" versus 0.350"). PCB layout verification is necessary to confirm mechanical fit within the existing footprint constraints.

Frequently Asked Questions (FAQ)

Q: Can the B82144B2562K000 be used as a direct replacement for the ELC-09D5R6DF?

A: Electrical substitution is valid based on matching 5.6 µH inductance and compatible current ratings. However, the significantly higher DC resistance requires thermal evaluation. Physical dimensions differ, requiring PCB layout verification before implementation.

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

A: The B82144B2562K000 DCR of 90mOhm maximum (versus 19mOhm in the original) increases resistive power loss by approximately 4.7 times at equivalent current levels. This generates additional heat within the inductor. Circuit thermal design must accommodate this increased dissipation to maintain safe operating temperatures.

Q: Are both parts RoHS compliant?

A: Yes, both the ELC-09D5R6DF and B82144B2562K000 are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and use.

Q: Will the substitute part fit in the existing PCB footprint?

A: Physical dimensions differ significantly. The substitute is smaller in diameter (6.50mm versus 9.50mm) but taller (14.00mm versus 8.90mm). PCB layout review is required to confirm mechanical compatibility with the existing design.

Q: What is the inductance tolerance difference between these parts?

A: The ELC-09D5R6DF specifies ±20% tolerance, while the B82144B2562K000 offers tighter ±10% tolerance. The substitute provides improved inductance value consistency, which may benefit circuit performance and reduce design margin requirements.

Q: Is the substitute part actively manufactured?

A: Yes, the B82144B2562K000 maintains active product status with EPCOS - TDK Electronics, ensuring ongoing availability and supply chain reliability compared to the obsolete ELC-09D5R6DF.
