ELC-06D331E Equivalent & Substitute Parts

Part Overview

The ELC-06D331E is a 330 µH unshielded through-hole inductor manufactured by Panasonic Electronic Components, rated for 300 mA with a DC resistance of 740mOhm. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity. Substitute parts must maintain the same inductance value, tolerance, mounting type, and current rating specifications to ensure functional compatibility in existing circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELC-06D331E are qualified based on the following critical parameters:

• Inductance Value: Must be 330 µH with ±10% tolerance
• Current Rating: Must support minimum 300 mA operation
• Mounting Type: Must be through-hole configuration
• Package / Case: Must be radial, vertical cylinder form factor
• Shielding: Must be unshielded
• RoHS Compliance: Must meet ROHS3 requirements

The substitute parts identified below satisfy these core electrical and mechanical requirements. Variations in DC resistance, core material, and operating temperature ranges are acceptable provided the primary functional parameters remain within specification.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are active products with ROHS3 compliance, providing long-term availability and regulatory alignment compared to the obsolete ELC-06D331E.

22R334C (Murata Power Solutions Inc.): This substitute offers a higher current rating of 380 mA, exceeding the original 300 mA specification. However, the DC resistance of 1.21Ohm Max is significantly higher than the original 740mOhm, which may impact circuit performance in applications sensitive to inductor losses. This part is suitable for designs where increased current headroom is beneficial and higher DCR is acceptable.

AIUR-16-331K (Abracon LLC): This substitute maintains the original 300 mA current rating and provides a DC resistance of 816mOhm Max, closely matching the original 740mOhm specification. The ferrite drum core construction and extended operating temperature range (-25°C ~ 85°C) provide enhanced thermal performance. This part is the preferred substitute for direct functional replacement with minimal circuit impact.

Both parts maintain identical inductance, tolerance, shielding, and mounting characteristics. Physical dimensions vary slightly but remain compatible with standard through-hole PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the 22R334C be used as a direct replacement for the ELC-06D331E?

A: The 22R334C meets the core electrical requirements (330 µH, ±10%, unshielded, through-hole). However, the DC resistance is 1.21Ohm compared to 740mOhm in the original part. This higher resistance will increase power dissipation and may affect circuit performance in applications with tight loss budgets. Verify circuit tolerance to increased DCR before substitution.

Q: What are the physical compatibility considerations?

A: All three parts use radial, vertical cylinder packaging suitable for through-hole PCB mounting. Dimensional variations are minor (diameter range 6.50mm to 7.00mm, height range 9.50mm to 10.50mm). Standard PCB layouts accommodate these tolerances without modification.

Q: Is the AIUR-16-331K the recommended substitute?

A: The AIUR-16-331K is the closest functional equivalent, maintaining the 300 mA current rating and providing DC resistance within 76mOhm of the original specification. It is the preferred choice for applications requiring minimal circuit redesign.

Q: Are both substitutes RoHS compliant?

A: Yes, both the 22R334C and AIUR-16-331K are ROHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the impact of different core materials?

A: The ELC-06D331E uses an unspecified core material, while the AIUR-16-331K uses ferrite. Both maintain the specified inductance and tolerance at the test frequency. Ferrite cores provide stable performance across the extended operating temperature range of the Abracon part.
