ELL-5PM680M Equivalent & Substitute Parts

Part Overview

The ELL-5PM680M is a 68 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 350 mA with a DC resistance of 700mOhm. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity. The part is designed for surface mount applications in nonstandard packaging with a compact footprint of 5.20mm x 5.20mm and a maximum seated height of 2.00mm.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELL-5PM680M is determined by the following critical parameters:

• Inductance Value: 68 µH ±20% tolerance
• Current Rating: 350 mA minimum
• DC Resistance: Maximum 700mOhm (lower values acceptable)
• Shielding: Shielded construction required
• Mounting Type: Surface mount only
• Inductance Test Frequency: 100 kHz

The ASPI-0428S-680M-T from Abracon LLC meets all substitution criteria. While it features a drum core ferrite construction compared to the original wirewound design, it maintains electrical equivalence across all critical parameters. The substitute part exhibits a slightly lower DC resistance of 699mOhm (within tolerance), identical inductance and current ratings, and equivalent shielding performance. Physical dimensions differ slightly (4.70mm x 4.70mm footprint, 3.00mm height), requiring PCB layout verification for mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ASPI-0428S-680M-T is the qualified substitute for the obsolete ELL-5PM680M based on the following factors:

Product Status: The Abracon part is active and in production, ensuring long-term availability and supply chain stability compared to the obsolete Panasonic component.

Electrical Equivalence: Both parts maintain identical inductance values, current ratings, and DC resistance within acceptable tolerances at the 100 kHz test frequency. The substitute's 699mOhm DCR is marginally lower than the original 700mOhm specification, which is electrically favorable.

Compliance and Certifications: The ASPI-0428S-680M-T carries ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements. The improved moisture sensitivity level (MSL 1 vs. MSL 2) provides superior handling and storage characteristics.

Physical Considerations: The substitute part is slightly smaller in footprint (4.70mm vs. 5.20mm) but taller (3.00mm vs. 2.00mm). PCB layout and component placement clearance must be verified before implementation.

Frequently Asked Questions (FAQ)

Q: Can the ASPI-0428S-680M-T directly replace the ELL-5PM680M without circuit redesign?

A: Electrical substitution is valid. The inductance, current rating, and DC resistance are equivalent. However, physical dimensions differ; verify PCB layout compatibility, particularly the increased height of 3.00mm versus 2.00mm.

Q: What is the significance of the different core materials (wirewound vs. drum core)?

A: Both constructions achieve the required inductance and current handling at 100 kHz. The drum core ferrite design in the substitute provides equivalent shielding and electrical performance for this application.

Q: Are there any compliance differences between the two parts?

A: The substitute part (ASPI-0428S-680M-T) is ROHS3 compliant with REACH unaffected status. The original part's compliance status is not specified. The substitute's MSL 1 rating also provides superior moisture protection compared to MSL 2.

Q: What is the packaging difference?

A: The ELL-5PM680M packaging is listed as nonstandard. The ASPI-0428S-680M-T is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes.

Q: Should I test the substitute before full production implementation?

A: Verification of PCB layout compatibility and mechanical clearance is required due to dimensional differences. Electrical performance is equivalent based on specified parameters.
