ELL-ATV150M Equivalent & Substitute Parts

Part Overview

The Panasonic ELL-ATV150M is a 15 µH shielded drum core wirewound inductor rated for 2.8 A with 32mOhm DC resistance, designed for surface mount applications. This part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production support. Substitute parts must maintain the same inductance value, core shielding characteristics, and current handling capability within acceptable tolerance ranges.

Substitute Part Grouping Explanation

Substitute parts for the ELL-ATV150M are selected based on the following critical parameters:

Inductance Value: 15 µH (exact match required)
Shielding Type: Shielded configuration (electromagnetic containment)
Current Rating: Minimum 2.8 A
DC Resistance: Within acceptable operating limits
Core Material: Ferrite
Mounting: Surface mount, nonstandard package
Tolerance: ±20% or tighter

All listed substitutes maintain the 15 µH inductance specification and ferrite core construction. Shielded variants (B82464G4153M000, B82464P4153M000, SRU1038-150Y) are direct functional equivalents. The unshielded variant (SDR1045-150M) is included for applications where electromagnetic shielding is not required.

Engineering Selection Recommendations

Primary Substitutes (Shielded, Direct Equivalents):

SRU1038-150Y (Bourns): Closest match to ELL-ATV150M. Maintains 2.8 A current rating, shielded configuration, and identical footprint dimensions (10.00 x 10.00mm). Active product status with ROHS3 compliance. Slightly higher DCR (37mOhm vs 32mOhm) and wider tolerance (±30%) are acceptable for most applications.
B82464G4153M000 (EPCOS - TDK Electronics): Active product with extended operating temperature range (-55°C ~ 150°C) and AEC-Q200 automotive qualification. Shielded configuration with 2.75 A rating. Slightly larger footprint (10.40 x 10.40mm) and higher DCR (40mOhm Max) require PCB layout verification.
B82464P4153M000 (EPCOS - TDK Electronics): Functionally identical to B82464G4153M000 with same electrical specifications and AEC-Q200 rating. Packaging variant with different HTSUS classification.

Secondary Substitute (Unshielded):

SDR1045-150M (Bourns): Suitable only for applications where electromagnetic shielding is not required. Lower current rating (2.5 A) and significantly higher DCR (100mOhm Max) limit applicability. Active product status with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can I use SDR1045-150M as a direct replacement for ELL-ATV150M?

A: SDR1045-150M is not a direct replacement. While it maintains the 15 µH inductance and ferrite core, it is unshielded and has lower current rating (2.5 A vs 2.8 A) and significantly higher DC resistance (100mOhm vs 32mOhm). Use only if your circuit does not require shielding and can tolerate higher power dissipation.

Q: What is the difference between B82464G4153M000 and B82464P4153M000?

A: Both parts are electrically and mechanically identical with the same 15 µH inductance, 2.75 A rating, 40mOhm Max DCR, and AEC-Q200 qualification. The difference is in packaging classification and HTSUS codes. Selection between them depends on supply chain and tariff requirements.

Q: Will SRU1038-150Y work in my existing PCB designed for ELL-ATV150M?

A: SRU1038-150Y has identical footprint dimensions (10.00 x 10.00mm) and is mechanically compatible. Verify that the slightly lower height (4.10mm vs 4.50mm) does not affect clearance requirements. Electrical performance is equivalent for most applications.

Q: Why is the ELL-ATV150M obsolete?

A: The ELL-ATV150M is classified as obsolete by Panasonic. Active substitutes from EPCOS - TDK Electronics and Bourns Inc. provide equivalent or superior specifications with ongoing production support and availability.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitutes (B82464G4153M000, B82464P4153M000, SDR1045-150M, SRU1038-150Y) are ROHS3 compliant and suitable for applications requiring environmental compliance.

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

A: Higher DCR increases power dissipation and heat generation. B82464 series (40mOhm) and SDR1045-150M (100mOhm) have higher DCR than the original (32mOhm). Thermal analysis is recommended for high-current or continuous-duty applications. SRU1038-150Y (37mOhm) has minimal impact.
