ELL-6GG150M Equivalent & Substitute Parts

Part Overview

The ELL-6GG150M is a 15 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 900 mA continuous current with 210mOhm DC resistance. This component is classified as obsolete, making substitute parts necessary for ongoing production and maintenance applications. The part operates at 100 kHz test frequency and is housed in a nonstandard 6.00mm x 6.00mm surface mount package with 1.60mm maximum seated height.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELL-6GG150M is determined by the following critical parameters:

Mandatory Matching Criteria:

• Inductance value: 15 µH ±20%
• Shielding: Shielded construction required
• Mounting type: Surface mount only
• Package footprint: 6.00mm x 6.00mm base dimensions
• Test frequency: 100 kHz

Allowable Variation Criteria:

• Current rating: Substitute must equal or exceed 900 mA
• Saturation current: Substitute must equal or exceed 800 mA
• DC resistance: Substitute may be lower (improved performance) but not significantly higher
• Height: Substitute may vary within PCB assembly constraints
• Core material: Ferrite or wirewound acceptable if electrical parameters are met

The NR6045T150M from Taiyo Yuden meets all mandatory criteria and exceeds performance specifications in current handling and DC resistance, qualifying it as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The NR6045T150M qualifies as a functional substitute based on electrical parameter equivalence and regulatory compliance. Both parts are ROHS3 compliant with MSL 1 ratings, ensuring compatibility in standard manufacturing environments.

Performance Advantages of NR6045T150M:

• Current rating of 1.9 A provides 111% margin above the original 900 mA specification
• DC resistance of 100.1 mOhm represents 52% reduction compared to 210 mOhm, resulting in lower power dissipation
• Saturation current of 2.3 A exceeds original 800 mA specification by 188%

Physical Consideration: The NR6045T150M height of 4.50mm exceeds the original 1.60mm specification. PCB layout verification is required to confirm clearance compatibility in the target application.

Product Status Impact: Both parts carry end-of-life or restricted status. The ELL-6GG150M is classified as obsolete, while the NR6045T150M is marked "Not For New Designs." For new product development, consultation with component suppliers for current production alternatives is advised.

Frequently Asked Questions (FAQ)

Q: Can the NR6045T150M directly replace the ELL-6GG150M in existing designs?

A: Electrical substitution is valid based on matching inductance (15 µH), tolerance (±20%), shielding, and test frequency (100 kHz). Physical verification of the 4.50mm height against available PCB clearance is mandatory before implementation.

Q: What does the ±20% inductance tolerance mean for substitution?

A: Both parts maintain ±20% tolerance at 100 kHz test frequency. This tolerance band is identical between the original and substitute, ensuring equivalent circuit performance within specified limits.

Q: Why is the DC resistance lower in the NR6045T150M?

A: The NR6045T150M uses a drum core ferrite construction versus the wirewound design of the ELL-6GG150M. Lower DC resistance (100.1 mOhm vs 210 mOhm) reduces resistive losses and heat generation, representing an improvement in efficiency.

Q: Are there compliance concerns with using the NR6045T150M?

A: Both parts are ROHS3 compliant with MSL 1 ratings. No compliance barriers exist for standard manufacturing and storage conditions. REACH status for the substitute is listed as unaffected.

Q: What is the significance of the 10 MHz self-resonant frequency specification?

A: The NR6045T150M specifies 10 MHz self-resonant frequency, indicating the frequency at which the inductor transitions from inductive to capacitive behavior. This parameter is not provided for the original part but indicates the substitute maintains stable inductive characteristics well above the 100 kHz operating point.

Q: Can height difference affect PCB assembly?

A: The 4.50mm height of the NR6045T150M versus 1.60mm original requires verification against component placement constraints, solder reflow profiles, and adjacent component clearances. Height compatibility must be confirmed in the specific PCB layout before production implementation.
