ELL-6SH561M Equivalent & Substitute Parts

Part Overview

The ELL-6SH561M is a 560 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 180 mA continuous current with 3.7Ohm DC resistance. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The part is RoHS3 compliant with MSL 1 rating, suitable for surface mount applications in standard operating environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELL-6SH561M is determined by the following critical parameters:

• Inductance Value: Must be 560 µH at 100 kHz test frequency
• Current Rating: Minimum 180 mA continuous current capability
• DC Resistance: Maximum 3.7Ohm to maintain circuit performance
• Shielding: Must be shielded construction
• Mounting: Surface mount configuration required
• Compliance: RoHS3 compliance and MSL 1 rating required

The SRR5028-561Y from Bourns Inc. meets these substitution criteria with equivalent inductance and shielding characteristics, though with modified current and resistance specifications within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

The SRR5028-561Y qualifies as a functional substitute based on matching inductance value, shielded construction, surface mount configuration, and equivalent compliance certifications (RoHS3, MSL 1). Both components are rated for 100 kHz inductance measurement and maintain shielded wirewound construction.

The primary design consideration is current derating: the SRR5028-561Y is rated for 140 mA versus the original 180 mA specification. Applications operating at or below 140 mA continuous current are directly compatible. Applications requiring the full 180 mA rating require thermal and circuit analysis to confirm the substitute's suitability.

The SRR5028-561Y exhibits slightly higher DC resistance (3.92Ohm max versus 3.7Ohm) and broader inductance tolerance (±30% versus ±20%), which may affect circuit performance in precision applications. The smaller footprint (5.80mm x 5.80mm versus 6.40mm x 6.00mm) provides layout advantages with reduced height (3.00mm versus 3.30mm).

Active product status of the SRR5028-561Y ensures long-term availability and supply chain continuity compared to the obsolete ELL-6SH561M.

Frequently Asked Questions (FAQ)

Q: Can the SRR5028-561Y directly replace the ELL-6SH561M in all applications?

A: Direct replacement is valid for applications operating at 140 mA or below. Applications requiring the full 180 mA rating require circuit analysis to confirm the substitute's thermal and electrical performance under maximum load conditions.

Q: What is the impact of the higher DC resistance in the SRR5028-561Y?

A: The SRR5028-561Y exhibits 3.92Ohm maximum resistance versus 3.7Ohm in the original part. This 0.22Ohm difference increases resistive losses proportionally to current squared. At 140 mA, the additional loss is approximately 8.6 mW, which may be negligible in most applications but requires verification in power-sensitive designs.

Q: Does the broader inductance tolerance of the SRR5028-561Y affect circuit performance?

A: The SRR5028-561Y tolerance of ±30% versus ±20% for the ELL-6SH561M represents a wider specification band. Applications with tight inductance requirements (resonant circuits, precision filters) require validation that the substitute's tolerance range remains acceptable for circuit function.

Q: Are the physical dimensions compatible with the original PCB layout?

A: The SRR5028-561Y is smaller (5.80mm x 5.80mm versus 6.40mm x 6.00mm) with reduced height (3.00mm versus 3.30mm). PCB footprints designed for the ELL-6SH561M will accommodate the substitute with clearance margin. Verify that the nonstandard package dimensions match your specific PCB design.

Q: What compliance certifications apply to both parts?

A: Both the ELL-6SH561M and SRR5028-561Y are RoHS3 compliant with MSL 1 (unlimited moisture sensitivity level) rating, ensuring equivalent environmental and regulatory compliance for standard applications.
