ELL-6SH681M Equivalent & Substitute Parts

Part Overview

The ELL-6SH681M is a 680 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 160 mA with 4.3Ohm DC resistance. This component is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production requirements. The part operates at 100 kHz test frequency and is housed in a nonstandard surface mount package measuring 6.40mm × 6.00mm × 3.30mm (max height).

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELL-6SH681M are selected based on the following critical parameters:

• Inductance Value: 680 µH (primary electrical requirement)
• Inductance Tolerance: ±20% or tighter (electrical performance margin)
• Current Rating: Equal to or greater than 160 mA (operational safety)
• DC Resistance: 4.3Ohm or lower (power loss consideration)
• Shielding: Shielded configuration (electromagnetic compatibility)
• Mounting Type: Surface Mount (physical compatibility)
• Package Compliance: ROHS3 compliant, MSL 1 (regulatory and environmental requirements)

Two substitute parts meet these criteria: B82462G4684M000 (EPCOS - TDK Electronics) and SRR5028-681Y (Bourns Inc.). Both maintain the 680 µH inductance specification, shielded wirewound construction, and surface mount configuration required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

B82462G4684M000 is the primary substitute for the ELL-6SH681M. This EPCOS - TDK Electronics component exceeds the current rating requirement at 200 mA versus the original 160 mA specification, provides improved DC resistance at 4.05Ohm maximum, and maintains active product status with AEC-Q200 automotive qualification. The operating temperature range of -55°C to 150°C provides extended thermal performance. Physical dimensions (6.30mm × 6.30mm × 3.00mm max) are compatible with the original footprint, and ROHS3 compliance with MSL 1 rating ensures regulatory alignment.

SRR5028-681Y is an alternative substitute manufactured by Bourns Inc. This component maintains identical inductance and DC resistance specifications to the original part. However, the current rating of 130 mA falls below the original 160 mA requirement, making this substitute suitable only for applications where the actual operating current does not exceed 130 mA. The inductance tolerance of ±30% is wider than the original ±20% specification. Physical dimensions (5.80mm × 5.80mm × 3.00mm max) are smaller, which may provide layout advantages. Operating temperature range of -40°C to 125°C and active product status support ongoing availability.

Selection between these substitutes depends on application current requirements and thermal operating conditions. B82462G4684M000 is recommended for designs requiring the full 160 mA current capacity or extended temperature performance. SRR5028-681Y is suitable for lower-current applications where the 130 mA rating is sufficient.

Frequently Asked Questions (FAQ)

Q: Can B82462G4684M000 directly replace ELL-6SH681M in all applications?

A: Yes, for applications operating at or below 160 mA. The B82462G4684M000 exceeds the current rating at 200 mA, maintains the 680 µH inductance specification, and provides equivalent or superior DC resistance performance. Physical dimensions are compatible with standard surface mount assembly processes.

Q: Why is SRR5028-681Y listed as a substitute if its current rating is lower?

A: SRR5028-681Y meets the core electrical specifications (680 µH inductance, 4.3Ohm DCR, shielded wirewound construction) and is suitable for applications where actual operating current does not exceed 130 mA. The lower current rating does not disqualify it as a substitute; rather, it defines the application scope where it can be used.

Q: Are there physical footprint compatibility concerns with these substitutes?

A: B82462G4684M000 (6.30mm × 6.30mm) and SRR5028-681Y (5.80mm × 5.80mm) are both smaller than the original ELL-6SH681M (6.40mm × 6.00mm). Both substitutes fit within the original footprint envelope. Height specifications (3.00mm max for both substitutes versus 3.30mm for the original) provide additional clearance margin.

Q: What is the significance of the inductance tolerance difference between substitutes?

A: The original ELL-6SH681M specifies ±20% tolerance. B82462G4684M000 maintains this ±20% tolerance, ensuring equivalent inductance accuracy. SRR5028-681Y specifies ±30% tolerance, which is wider and may impact circuit performance in applications with tight inductance requirements. For precision-dependent circuits, B82462G4684M000 is the preferred substitute.

Q: Are both substitutes suitable for automotive applications?

A: B82462G4684M000 carries AEC-Q200 automotive qualification, making it suitable for automotive-grade applications. SRR5028-681Y does not specify automotive qualification. For automotive or automotive-grade applications, B82462G4684M000 is the appropriate choice.

Q: What is the impact of different core materials on performance?

A: The original ELL-6SH681M does not specify core material. Both substitutes use ferrite drum core construction. Ferrite cores provide shielding effectiveness and stable inductance across the operating frequency range. The 100 kHz test frequency specification is maintained by both substitutes, ensuring consistent performance in the intended application bandwidth.
