ELC-09D220DF Equivalent & Substitute Parts

Part Overview

The ELC-09D220DF is a 22 µH unshielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 1.8 A with 51mOhm DC resistance. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The part is mounted through-hole in a radial, vertical cylinder package and complies with ROHS3 standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELC-09D220DF is determined by the following critical parameters:

• Inductance Value: Must be 22 µH to maintain circuit function
• Mounting Type: Must be through-hole to ensure PCB compatibility
• Package Configuration: Must be radial, vertical cylinder to fit existing board layouts
• Current Rating: Must meet or exceed 1.8 A minimum requirement
• DC Resistance: Should be comparable to 51mOhm to avoid circuit performance degradation
• Shielding: Unshielded configuration must be maintained
• Compliance: ROHS3 compliance required for regulatory alignment

The AIUR-09-220M from Abracon LLC meets these substitution criteria with compatible electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The AIUR-09-220M is a suitable substitute for the obsolete ELC-09D220DF based on the following factors:

• Both components maintain identical 22 µH inductance specification
• Both are ROHS3 compliant, meeting current regulatory requirements
• The AIUR-09-220M is active in production, ensuring long-term availability
• Current rating of 2.4 A exceeds the 1.8 A requirement, providing operational margin
• Through-hole radial, vertical cylinder configuration ensures PCB footprint compatibility
• The AIUR-09-220M features a ferrite drum core construction versus the original wirewound design

Differences in DC resistance (92mOhm max versus 51mOhm) and inductance tolerance (±20% versus ±10%) must be evaluated against specific circuit requirements to confirm suitability for the intended application.

Frequently Asked Questions (FAQ)

Q: Can the AIUR-09-220M directly replace the ELC-09D220DF on existing PCBs?

A: Physical compatibility is confirmed. Both components use through-hole radial, vertical cylinder packaging. The AIUR-09-220M diameter is 0.394" (10.00mm) compared to 0.374" (9.50mm), and height is 0.256" (6.50mm) compared to 0.350" (8.90mm). Board layout verification is required to confirm clearance.

Q: What is the impact of the higher DC resistance in the AIUR-09-220M?

A: The AIUR-09-220M specifies 92mOhm maximum DCR versus 51mOhm for the original part. This increased resistance will result in higher power dissipation at rated current. Circuit thermal analysis is necessary to determine if this difference affects performance or reliability.

Q: Does the ±20% inductance tolerance of the AIUR-09-220M affect circuit function?

A: The wider tolerance must be evaluated against circuit design margins. Applications with tight inductance specifications may require additional filtering or compensation to maintain performance within the ±20% tolerance band.

Q: Are both parts suitable for the same operating temperature range?

A: The ELC-09D220DF does not specify an operating temperature range. The AIUR-09-220M is rated -55°C ~ 85°C. Confirm that this range meets application requirements.

Q: What is the difference between wirewound and drum core construction?

A: The ELC-09D220DF uses wirewound construction, while the AIUR-09-220M uses drum core, ferrite construction. Both achieve the same 22 µH inductance but with different core materials and winding methods, resulting in different electrical characteristics including DCR and frequency response.
