ELL-6GG101M Equivalent & Substitute Parts

Part Overview

The ELL-6GG101M is a 100 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 350 mA continuous current with 1.48Ohm DC resistance. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing production support and design continuity. The part features surface mount packaging in a 6.00mm x 6.00mm nonstandard case with 1.60mm maximum seated height and is ROHS3 compliant with unlimited moisture sensitivity rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELL-6GG101M is determined by the following critical parameters:

• Inductance value: 100 µH ±20% tolerance
• Shielding requirement: Shielded construction
• Mounting type: Surface mount
• Physical footprint: 6.00mm x 6.00mm base dimensions
• Current handling: Minimum 350 mA continuous rating
• Saturation current: Minimum 300 mA
• DC resistance: Comparable performance (lower DCR preferred for reduced losses)
• Test frequency: 100 kHz measurement standard

The substitute part NRS6028T101MMGJ from Taiyo Yuden meets these core substitution criteria with equivalent inductance, shielding, mounting type, and footprint dimensions. The substitute demonstrates superior electrical performance with 660 mA current rating, 650 mA saturation current, and significantly lower 780 mOhm DC resistance compared to the original part.

Parameter Comparison

Engineering Selection Recommendations

The NRS6028T101MMGJ qualifies as a direct substitute for the ELL-6GG101M based on matching inductance value, tolerance, shielding, mounting type, and footprint dimensions. Both components maintain ROHS3 compliance and unlimited moisture sensitivity rating.

The substitute part provides enhanced electrical performance with 88% reduction in DC resistance (780 mOhm versus 1.48 Ohm) and 88% increase in current rating capacity (660 mA versus 350 mA). The substitute's maximum seated height of 2.80mm exceeds the original 1.60mm specification; PCB layout clearance verification is required for space-constrained applications.

Both components carry end-of-life status designations. The original part is classified as obsolete, while the substitute is marked "Not For New Designs," indicating limited long-term availability. For new production designs, evaluation of actively supported alternatives from the substitute's secondary reference list (BWVS00606028101T00, SDCH1V6028-101M-R, LMLP06C6M101CTAS, LSXND6060WHL101MMG) is recommended.

Frequently Asked Questions (FAQ)

Q: Can NRS6028T101MMGJ directly replace ELL-6GG101M in existing designs?

A: Yes, for applications where the increased height (2.80mm versus 1.60mm) does not create PCB layout conflicts. The substitute maintains identical inductance, tolerance, shielding, and footprint dimensions. Verify available vertical clearance on your PCB assembly before implementation.

Q: What is the significance of the lower DC resistance in the substitute part?

A: The NRS6028T101MMGJ exhibits 780 mOhm DC resistance compared to 1.48 Ohm in the original part. Lower DC resistance reduces resistive losses and heat generation in the inductor, improving circuit efficiency. This represents a performance enhancement for equivalent inductance value.

Q: Are both parts suitable for new product designs?

A: Neither component is recommended for new designs. The ELL-6GG101M is obsolete; the NRS6028T101MMGJ is marked "Not For New Designs." For new development, select from actively supported inductors meeting your 100 µH, 350+ mA, shielded surface mount requirements.

Q: What is the difference between wirewound and drum core construction?

A: Both the original ELL-6GG101M (wirewound) and substitute NRS6028T101MMGJ (drum core wirewound) are wirewound inductors. The drum core design in the substitute provides the ferrite core structure that contributes to improved DC resistance and current handling characteristics.

Q: How do I verify compatibility for my specific application?

A: Confirm that your circuit design accommodates the substitute's 2.80mm maximum height. Verify that the 660 mA current rating and 650 mA saturation current of the substitute meet or exceed your application requirements. Both parts operate at 100 kHz test frequency with ±20% inductance tolerance.
