ELL-ATV2R2N Equivalent & Substitute Parts

Part Overview

The ELL-ATV2R2N is a 2.2 µH shielded drum core wirewound inductor manufactured by Panasonic Electronic Components, rated for 6.2 A continuous current with 6.3mOhm DC resistance. This surface mount component is designed for applications requiring compact, shielded inductance in nonstandard packaging. The part is currently obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications.

Substitute Part Grouping Explanation

Substitute parts for the ELL-ATV2R2N are qualified based on the following critical parameters:

Inductance Value: 2.2 µH (exact match required)
Inductance Tolerance: ±30% (matching tolerance band)
Current Rating: Minimum 6.2 A (equal or greater)
DC Resistance: Maximum 6.3mOhm (lower or equal preferred for thermal performance)
Core Material: Ferrite, shielded construction
Mounting Type: Surface mount
Physical Footprint: Nonstandard 10.00mm x 10.00mm base dimensions
Compliance: ROHS3 compliant, MSL 1

The two qualified substitutes meet these criteria while offering improved availability and active product status.

Engineering Selection Recommendations

Primary Substitute: SRU1038-2R2Y (Bourns Inc.)

The SRU1038-2R2Y is the preferred substitute for new designs and ongoing production. It maintains active product status, ensuring long-term availability and supply chain stability. The part exceeds the current rating requirement (6.8 A vs. 6.2 A), offers lower DC resistance (7.7mOhm vs. 6.3mOhm baseline), and provides the lowest seated height (4.10mm), optimizing PCB space utilization. Full ROHS3 compliance and REACH unaffected status confirm regulatory alignment.

Secondary Substitute: NS10145T2R2NNA (Taiyo Yuden)

The NS10145T2R2NNA meets all functional requirements with higher current rating (6.64 A) and saturation current specification (8.91A). However, the part carries "Not For New Designs" status, limiting its suitability for new product development. DC resistance is higher at 10mOhm maximum, resulting in increased thermal dissipation. This substitute is suitable for legacy system maintenance where supply continuity is prioritized over new design optimization.

Both substitutes maintain identical inductance value, tolerance, shielding, core material, and compliance certifications as the original ELL-ATV2R2N.

Frequently Asked Questions (FAQ)

Q: Can the NS10145T2R2NNA and SRU1038-2R2Y be used interchangeably with the ELL-ATV2R2N?

A: Both substitutes meet the core electrical specifications (2.2 µH inductance, ±30% tolerance, minimum 6.2 A current rating, shielded ferrite drum core). Physical dimensions are within acceptable tolerance for standard PCB footprints. However, the SRU1038-2R2Y is recommended for new designs due to active product status.

Q: What is the impact of different DC resistance values on circuit performance?

A: The ELL-ATV2R2N specifies 6.3mOhm DCR. The SRU1038-2R2Y (7.7mOhm) introduces 22% higher resistance, increasing I²R losses proportionally. The NS10145T2R2NNA (10mOhm maximum) introduces 59% higher resistance. In high-current applications, this affects thermal performance and efficiency. Select based on thermal budget requirements.

Q: Are there height clearance considerations for PCB layout?

A: The original ELL-ATV2R2N has a seated height of 4.50mm. The SRU1038-2R2Y is lower at 4.10mm, providing additional clearance. The NS10145T2R2NNA is taller at 4.85mm, requiring verification against PCB assembly constraints and component stacking requirements.

Q: Do all substitutes meet the same compliance requirements?

A: All three parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. The SRU1038-2R2Y and NS10145T2R2NNA both specify REACH unaffected status, confirming regulatory alignment for global markets.

Q: What is the significance of "Not For New Designs" status on the NS10145T2R2NNA?

A: This designation indicates the manufacturer is not recommending the part for new product development. While the part remains functionally qualified and available, it may have limited long-term supply guarantees. For production continuity, the SRU1038-2R2Y (active status) is the preferred choice.
