ELL-VGG120M Equivalent & Substitute Parts

Part Overview

The ELL-VGG120M is a 12 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 580 mA continuous current with 480mOhm DC resistance. This component is classified as obsolete, making equivalent substitutes necessary for ongoing design support and procurement continuity. The part is surface-mounted in a nonstandard 3.00mm x 3.00mm package with ROHS3 compliance and unlimited moisture sensitivity rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELL-VGG120M is determined by the following critical parameters:

• Inductance Value: Must be 12 µH at 100 kHz test frequency
• Shielding: Must be shielded to maintain electromagnetic isolation
• Mounting Type: Must be surface mount compatible
• Package Footprint: Must accommodate 3.00mm x 3.00mm dimensions
• Current Handling: Substitute must support minimum 580 mA continuous current rating
• DC Resistance: Lower or equivalent DCR is acceptable; higher values require circuit validation
• Saturation Current: Must exceed or equal 690 mA minimum threshold
• Compliance: ROHS3 compliance required for regulatory alignment

The CDRH2D14NP-120NC meets these substitution criteria with compatible electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The CDRH2D14NP-120NC is a direct substitute for the obsolete ELL-VGG120M based on the following factors:

• Active Product Status: The substitute is actively manufactured and stocked, ensuring long-term availability and supply chain continuity.
• Identical Inductance and Footprint: Both components share 12 µH inductance at 100 kHz and 3.00mm x 3.00mm surface-mount dimensions, enabling direct PCB layout compatibility.
• Enhanced Current Capacity: The substitute provides 640 mA continuous current rating, exceeding the main part's 580 mA specification.
• Improved DC Resistance: The substitute's 394 mOhm maximum DCR is lower than the main part's 480 mOhm, resulting in reduced power dissipation.
• Regulatory Compliance: Both components maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).
• Height Compatibility: The substitute's 1.55mm seated height is marginally higher than the main part's 1.50mm but remains within typical PCB assembly tolerances for nonstandard packages.

The wider inductance tolerance (±30% vs. ±20%) and slightly lower saturation current (620 mA vs. 690 mA) of the substitute require circuit-level validation in applications with tight inductance specifications or near-saturation operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the CDRH2D14NP-120NC be used as a direct replacement for the ELL-VGG120M?

A: Yes. Both components share identical 12 µH inductance, 3.00mm x 3.00mm footprint, shielded construction, and surface-mount configuration. The substitute meets or exceeds the main part's electrical specifications for current rating and DC resistance.

Q: What are the key differences between these two inductors?

A: The primary differences are inductance tolerance (±20% vs. ±30%), saturation current (690 mA vs. 620 mA), and product status (obsolete vs. active). The substitute offers lower DC resistance (394 mOhm vs. 480 mOhm) and higher continuous current capacity (640 mA vs. 580 mA).

Q: Does the height difference of 0.05mm (1.50mm vs. 1.55mm) affect PCB assembly?

A: The 0.05mm height difference is negligible for standard surface-mount assembly processes and falls within typical component placement tolerances. No PCB redesign is required.

Q: Are both components RoHS compliant?

A: Yes. Both the ELL-VGG120M and CDRH2D14NP-120NC are ROHS3 compliant with unlimited moisture sensitivity (MSL 1).

Q: Which component should be selected for new designs?

A: The CDRH2D14NP-120NC should be selected for new designs due to its active product status, improved electrical performance, and guaranteed long-term availability.

Q: What is the impact of the wider inductance tolerance on circuit performance?

A: The substitute's ±30% tolerance is wider than the main part's ±20%. Applications requiring tight inductance specifications should include tolerance analysis or select components with tighter binning if available from the manufacturer.
