ELC-08D2R2E Equivalent & Substitute Parts

Part Overview

The ELC-08D2R2E is a 2.2 µH fixed unshielded inductor manufactured by Panasonic Electronic Components, rated for 7.2 A continuous current with 10mOhm DC resistance. This through-hole radial component is designed for applications requiring low inductance values with moderate current handling capability. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. Substitute parts must maintain the same inductance value, tolerance, and core material while meeting or exceeding the current rating and DC resistance specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELC-08D2R2E is determined by the following critical parameters:

• Inductance Value: Must be 2.2 µH with ±20% tolerance
• Core Material: Ferrite core required
• Mounting Type: Through-hole radial configuration mandatory
• Current Rating: Must meet or exceed 7.2 A
• DC Resistance: Must not exceed 10mOhm to maintain equivalent performance characteristics
• RoHS Compliance: ROHS3 compliance required for regulatory alignment

Three substitute parts meet these criteria: 7447471022 (Würth Elektronik WE-TIS series), 744772022 (Würth Elektronik WE-TI series), and RCH108NP-2R2M (Sumida America RCH-108 series). Each substitute maintains the specified inductance and tolerance while offering improved or equivalent electrical performance.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with ROHS3 compliance, providing long-term availability and regulatory alignment superior to the obsolete ELC-08D2R2E.

744772022 (Würth Elektronik WE-TI) provides the closest electrical match with identical 10mOhm maximum DC resistance and unshielded configuration. Current rating of 6.7 A is below the original 7.2 A specification; this part is suitable only for applications where the actual operating current does not exceed 6.7 A.

7447471022 (Würth Elektronik WE-TIS) offers the highest current rating at 8.2 A with superior DC resistance of 8.8mOhm maximum and extended operating temperature range (-40°C to 125°C). The shielded configuration provides additional electromagnetic isolation. This part exceeds the original specifications and is suitable for applications requiring enhanced performance margins.

RCH108NP-2R2M (Sumida America RCH-108) delivers 7.9 A current rating with 8.5mOhm maximum DC resistance, closely matching the original 7.2 A rating. Operating temperature range extends to -40°C to 100°C. This part provides balanced performance improvement with unshielded configuration matching the original design intent.

Frequently Asked Questions (FAQ)

Q: Can 744772022 replace ELC-08D2R2E in all applications?

A: No. The 744772022 has a maximum current rating of 6.7 A, which is below the original 7.2 A specification. Use this substitute only in applications where actual operating current does not exceed 6.7 A.

Q: What is the difference between shielded and unshielded configurations?

A: The 7447471022 features shielding, which reduces electromagnetic radiation and susceptibility to external interference. The ELC-08D2R2E, 744772022, and RCH108NP-2R2M are unshielded. Shielded parts are suitable for noise-sensitive applications but occupy larger physical space.

Q: Are all substitutes physically compatible with the original PCB footprint?

A: Physical dimensions differ among substitutes. The ELC-08D2R2E measures 0.315" diameter by 0.512" height. The 7447471022 measures 0.433" diameter by 0.453" height, and the 744772022 measures 0.307" diameter by 0.394" height. Verify PCB layout clearance before substitution.

Q: Do all substitutes meet the same compliance requirements?

A: Yes. All three substitutes are ROHS3 compliant and carry EAR99 ECCN classification, matching the original part's regulatory status.

Q: Which substitute offers the best long-term availability?

A: All three substitutes are active products from established manufacturers (Würth Elektronik and Sumida America), providing superior long-term availability compared to the obsolete ELC-08D2R2E.
