ELC-06D8R2E Equivalent & Substitute Parts

Part Overview

The ELC-06D8R2E is an 8.2 µH unshielded through-hole inductor manufactured by Panasonic Electronic Components, rated for 1.8 A with 48mOhm DC resistance. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The part belongs to the 06D series and is fully RoHS3 compliant with MSL Level 1 rating.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELC-06D8R2E are qualified based on the following critical parameters:

• Inductance Value: Must be 8.2 µH (exact match)
• Inductance Tolerance: ±20% or tighter acceptable
• Current Rating: Minimum 1.8 A (equal or higher acceptable)
• DC Resistance: 48mOhm baseline (higher values acceptable within thermal constraints)
• Mounting Type: Through Hole (required)
• Package / Case: Radial, Vertical Cylinder (required)
• Shielding: Unshielded (required)
• Compliance: RoHS3 compliant (required)

Two substitute parts meet these criteria: B82144B2822K000 (EPCOS - TDK Electronics) and RCH855NP-8R2M (Sumida America Components Inc.). Both maintain the 8.2 µH inductance specification, through-hole radial mounting, and unshielded configuration while offering improved current ratings and active product status.

Parameter Comparison

Engineering Selection Recommendations

B82144B2822K000 is recommended for applications requiring superior current handling capacity (2.65 A) and tighter inductance tolerance (±10%). This part features active product status with extended operating temperature range (-55°C ~ 125°C) and is manufactured by EPCOS - TDK Electronics, a major inductor supplier. The higher DC resistance (105mOhm Max) and increased height (14.00mm) must be evaluated against thermal and spatial constraints in the target application.

RCH855NP-8R2M is recommended for applications with minimal height constraints (5.50mm seated height) and where DC resistance performance is critical (45mOhm Max, lower than the original 48mOhm specification). This part maintains active product status and is supplied by Sumida America Components Inc. The slightly larger diameter (7.80mm) and marginally higher current rating (1.9 A) provide minimal performance improvement over the original part while maintaining compatibility with the original electrical specifications.

Both substitutes are RoHS3 compliant and available in active production status, ensuring long-term procurement viability compared to the obsolete ELC-06D8R2E.

Frequently Asked Questions (FAQ)

Q: Can B82144B2822K000 be used as a direct replacement for ELC-06D8R2E?

A: Yes, B82144B2822K000 meets all critical substitution parameters: 8.2 µH inductance, through-hole radial mounting, unshielded configuration, and RoHS3 compliance. The higher current rating (2.65 A vs. 1.8 A) and tighter tolerance (±10% vs. ±20%) provide performance margin. Physical dimensions differ slightly; verify PCB layout compatibility before implementation.

Q: What is the impact of higher DC resistance in B82144B2822K000?

A: The B82144B2822K000 has 105mOhm Max DCR compared to 48mOhm in the original part. This increases power dissipation proportionally to I²R losses. For a 1.8 A circuit, dissipation increases from approximately 155 mW to 340 mW. Thermal design review is required for applications with tight thermal budgets.

Q: Is RCH855NP-8R2M suitable for space-constrained designs?

A: Yes, RCH855NP-8R2M offers the lowest seated height (5.50mm) among the three parts, making it suitable for compact PCB layouts. The 45mOhm Max DCR is superior to the original 48mOhm specification, reducing thermal dissipation. Verify the 7.80mm diameter fits available board space.

Q: Are there packaging differences between these parts?

A: ELC-06D8R2E and RCH855NP-8R2M are supplied in standard through-hole formats. B82144B2822K000 is supplied in Cut Tape (CT) packaging, while RCH855NP-8R2M is supplied in Tape & Reel (TR). Confirm packaging compatibility with assembly processes and procurement workflows.

Q: Do all three parts support the same operating temperature range?

A: No. B82144B2822K000 operates from -55°C to 125°C, while RCH855NP-8R2M operates from -40°C to 100°C. The original ELC-06D8R2E operating temperature is not specified. Select the substitute based on the target application's thermal requirements.

Q: What is the inductance tolerance impact on circuit performance?

A: B82144B2822K000 offers ±10% tolerance versus ±20% for both ELC-06D8R2E and RCH855NP-8R2M. Tighter tolerance reduces circuit parameter variation and improves performance consistency in frequency-dependent applications. For DC-biased or non-critical inductance applications, the ±20% tolerance is typically acceptable.
