ELL-4GG2R2N Equivalent & Substitute Parts

Part Overview

The ELL-4GG2R2N is a 2.2 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 1.4 A continuous current with 88mOhm DC resistance. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part operates at 100 kHz inductance test frequency and is housed in a nonstandard 3.80mm x 3.80mm surface mount package with 1.40mm maximum seated height.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELL-4GG2R2N is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 2.2 µH (fixed requirement)
• Inductance test frequency: 100 kHz (measurement standard)
• Shielding: Shielded construction (electromagnetic containment requirement)
• Mounting type: Surface mount (PCB assembly compatibility)
• Current rating: Minimum 1.4 A continuous (operational envelope)
• Saturation current: Minimum 1.7 A (headroom requirement)

Secondary Compatibility Factors:

• DC resistance: Lower values preferred (reduced power dissipation)
• Package footprint: 4.00mm x 4.00mm maximum (PCB layout tolerance)
• Height: 1.80mm maximum seated height (assembly clearance)
• RoHS3 compliance (regulatory requirement)
• MSL rating: 1 (moisture sensitivity)

The NRS4018T2R2MDGJ from Taiyo Yuden meets all primary criteria with improved electrical performance characteristics, making it a direct functional substitute for the obsolete ELL-4GG2R2N.

Parameter Comparison

Engineering Selection Recommendations

The NRS4018T2R2MDGJ is the qualified substitute for the ELL-4GG2R2N based on the following engineering factors:

Electrical Performance: The substitute part exceeds the original specification in current rating (2.2 A vs. 1.4 A) and saturation current (3.0 A vs. 1.7 A), providing operational margin. DC resistance is reduced to 50.4 mOhm maximum, improving efficiency compared to the original 88 mOhm specification.

Inductance Accuracy: The substitute maintains the 2.2 µH inductance value with tighter tolerance (±20% vs. ±30%), ensuring more predictable circuit behavior at the 100 kHz test frequency.

Regulatory Compliance: Both parts are ROHS3 compliant with MSL rating 1, meeting environmental and moisture sensitivity requirements for surface mount assembly.

Physical Compatibility: The substitute footprint (4.00mm x 4.00mm) is slightly larger than the original (3.80mm x 3.80mm), and seated height increases from 1.40mm to 1.80mm. PCB layout verification is required to confirm clearance in existing designs.

Product Status Consideration: While the substitute is classified as "Not For New Designs," it remains available in production quantities (91,100 pcs in stock) and serves as the documented equivalent for the obsolete ELL-4GG2R2N.

Frequently Asked Questions (FAQ)

Q: Can the NRS4018T2R2MDGJ be used as a direct replacement for the ELL-4GG2R2N?

A: Yes, the NRS4018T2R2MDGJ meets all primary electrical requirements: identical 2.2 µH inductance, shielded construction, surface mount configuration, and exceeds the minimum current rating. Physical footprint verification is necessary due to the 0.20mm increase in length and width, and 0.40mm increase in height.

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

A: The primary differences are: (1) DC resistance is lower in the substitute (50.4 mOhm vs. 88 mOhm), reducing power dissipation; (2) current ratings are higher (2.2 A vs. 1.4 A continuous, 3.0 A vs. 1.7 A saturation); (3) inductance tolerance is tighter (±20% vs. ±30%); (4) the substitute specifies self-resonant frequency (60 MHz) and operating temperature range (-25°C ~ 120°C); (5) physical dimensions are slightly larger.

Q: Are there any package compatibility concerns?

A: The substitute package is 4.00mm x 4.00mm with 1.80mm maximum height, compared to the original 3.80mm x 3.80mm with 1.40mm height. PCB layout must be reviewed to confirm adequate clearance for component placement and solder reflow processes.

Q: Do both parts meet the same regulatory standards?

A: Yes, both the ELL-4GG2R2N and NRS4018T2R2MDGJ are ROHS3 compliant with MSL rating 1 (unlimited moisture sensitivity level). Both are classified under HTSUS code 8504.50.8000 and ECCN EAR99.

Q: Why is the substitute listed as "Not For New Designs"?

A: The "Not For New Designs" status indicates the manufacturer is phasing out this product line. However, it remains available in high inventory quantities and serves as the documented equivalent for the obsolete ELL-4GG2R2N. For new designs, consultation with the manufacturer for current-generation alternatives is recommended.

Q: What is the inductance test frequency, and why does it matter?

A: Both parts specify 100 kHz as the inductance test frequency, which is the standard measurement condition for inductor specifications. This ensures consistent comparison between the original and substitute parts at the same operating reference point.
