ELL-ATV1R5N Equivalent & Substitute Parts

Part Overview

The ELL-ATV1R5N is a 1.5 µH shielded drum core, wirewound inductor manufactured by Panasonic Electronic Components, rated for 6.7 A continuous current with 5.3mOhm DC resistance. This component is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. Equivalent alternatives maintain the same inductance value, tolerance, and core material while offering comparable or improved electrical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the ELL-ATV1R5N be directly replaced with any of these substitutes? A: Yes. All listed substitutes maintain the same 1.5 µH inductance value, ±30% tolerance, ferrite core material, and shielded construction. Current ratings and DC resistance values are within acceptable operating ranges for the ELL-ATV1R5N application envelope.

Q: What is the primary difference between the substitute options? A: The main differences are current rating capacity, DC resistance, height profile, and operating temperature range. SRU1048-1R5Y offers the lowest DC resistance (4.3mOhm) and highest inventory availability. SRU1038-1R5Y provides the lowest profile (4.10mm). CDRH105RNP-1R5NC delivers the highest current rating (8.3 A).

Q: Are there PCB layout considerations when switching to CDRH105RNP-1R5NC? A: Yes. The CDRH105RNP-1R5NC has a slightly larger length dimension (10.20mm vs. 10.00mm) and greater height (5.10mm vs. 4.50mm). PCB footprint and clearance verification is required before implementation.

Q: Do all substitutes support the same operating temperature range? A: No. The CDRH105RNP-1R5NC operates from -40°C to 100°C, while both Bourns options (SRU1038-1R5Y and SRU1048-1R5Y) support -40°C to 125°C. Select based on your application's thermal requirements.

Q: Which substitute offers the best performance for low-loss applications? A: The SRU1048-1R5Y has the lowest DC resistance at 4.3mOhm, minimizing resistive losses. Both Bourns parts provide documented Q factors and self-resonant frequencies for high-frequency performance analysis.

Q: Are all substitutes RoHS3 compliant? A: Yes. All three substitute parts are ROHS3 compliant with unlimited MSL ratings (1), meeting standard environmental and moisture sensitivity requirements.
