ELL-VGG2R2N Equivalent & Substitute Parts

Part Overview

The Panasonic ELL-VGG2R2N is a 2.2 µH shielded wirewound inductor rated for 1.4 A with 92mOhm DC resistance, designed for surface mount applications in a 3.00mm x 3.00mm nonstandard package. This part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production requirements. Substitute parts must maintain the same inductance value, compatible current ratings, and physical dimensions while meeting modern compliance standards.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Inductance Value: Must be 2.2 µH (all candidates meet this requirement)
Current Rating: Must support minimum 1.4 A continuous current
DC Resistance: Lower DCR values indicate better performance; higher values increase power dissipation
Physical Dimensions: Must fit 3.00mm x 3.00mm footprint with height compatibility
Shielding Type: Shielded or semi-shielded configurations are acceptable for EMI-sensitive applications
Product Status: Active parts are preferred over obsolete classifications
Compliance: ROHS3 compliance required for modern supply chains

All five substitute parts meet the core inductance, footprint, and compliance requirements. Variations in current rating, DCR, and shielding type allow selection based on specific application needs.

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility)

74404032022 (Würth Elektronik WE-LQS) and SRN3015-2R2M (Bourns SRN3015) are the preferred substitutes. Both parts support 1.8 A current rating, exceeding the original 1.4 A requirement, and feature lower DCR values (50 mOhm and 72 mOhm respectively) compared to the original 92 mOhm. Both are active products with ROHS3 compliance and -40°C to 125°C operating temperature range. The Würth part offers tighter inductance tolerance (±20%) and higher self-resonant frequency (75 MHz). The Bourns part provides measured Q factor data (10 @ 7.96 MHz) and higher self-resonant frequency (90 MHz).

Secondary Substitutes (Conditional Use)

LMLP0303N2R2CTAR (KYOCERA AVX LMLP) is suitable for applications with lower current demands. It provides the lowest profile height (1.00mm) and operates across -40°C to 125°C. However, the 1.1 A current rating is below the original specification and should only be selected if application current requirements do not exceed 1.1 A.

SD3114-2R2-R (Eaton SD3114) is compatible with slightly larger footprint dimensions (3.10mm x 3.10mm) and supports 1.17 A current rating. This part is suitable only if PCB layout permits the marginally larger footprint.

CDRH2D11/HPNP-2R2NC (Sumida CDRH2D11/HP) has the lowest current rating (1.3 A) and highest DCR (120 mOhm Max), making it the least favorable option. The reduced operating temperature range (-40°C to 105°C) further limits its applicability. Selection should be restricted to applications with current requirements below 1.3 A and standard industrial temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with lower current rating than the original ELL-VGG2R2N?

A: No. The original part is rated for 1.4 A continuous current. Substitute parts must support at least 1.4 A to maintain circuit performance and reliability. LMLP0303N2R2CTAR (1.1 A) and CDRH2D11/HPNP-2R2NC (1.3 A) fall below this threshold and are unsuitable for direct replacement unless application current requirements are confirmed to be lower.

Q: What is the impact of different DC resistance values on circuit performance?

A: DC resistance directly affects power dissipation and voltage drop across the inductor. Lower DCR values reduce heat generation and power loss. The original part has 92 mOhm DCR. Substitutes with lower DCR (50 mOhm for Würth, 72 mOhm for Bourns) improve efficiency. Higher DCR values (110-120 mOhm) increase power dissipation and should be avoided unless thermal budget permits.

Q: Are semi-shielded inductors acceptable replacements for shielded inductors?

A: Semi-shielded inductors (74404032022 and SRN3015-2R2M) provide reduced EMI containment compared to fully shielded designs. They are acceptable only if the application does not require full shielding for EMI compliance or if EMI testing confirms acceptable performance. For noise-sensitive circuits, fully shielded alternatives (LMLP0303N2R2CTAR, SD3114-2R2-R, CDRH2D11/HPNP-2R2NC) are preferred.

Q: Can I use the SD3114-2R2-R substitute if my PCB footprint is designed for 3.00mm x 3.00mm?

A: The SD3114-2R2-R has dimensions of 3.10mm x 3.10mm, which exceeds the original 3.00mm x 3.00mm footprint. Physical fit must be verified before selection. If PCB layout does not accommodate the larger footprint, this part is unsuitable.

Q: What is the significance of inductance tolerance in substitute selection?

A: Inductance tolerance defines the acceptable range of actual inductance values. The original part specifies ±30% tolerance. Würth (74404032022) and Bourns (SRN3015-2R2M) offer tighter ±20% tolerance, which may improve circuit performance consistency. All substitutes meet or exceed the original tolerance specification.

Q: Are all substitute parts ROHS3 compliant?

A: Five of six substitutes are explicitly ROHS3 compliant. Eaton SD3114-2R2-R is listed as RoHS Compliant without specific ROHS3 designation. For supply chains requiring ROHS3 certification, confirm compliance status with the supplier before procurement.

Q: What operating temperature range should I consider for substitute selection?

A: The original ELL-VGG2R2N does not specify operating temperature. All active substitutes operate across -40°C to 125°C except Sumida CDRH2D11/HPNP-2R2NC, which is limited to -40°C to 105°C. For applications requiring full industrial temperature range, avoid the Sumida part.
