ELL-VGG330M Equivalent & Substitute Parts

Part Overview

The ELL-VGG330M is a 33 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 340 mA continuous current with 1.33Ohm DC resistance. This component is classified as obsolete, making equivalent substitutes necessary for new designs and production continuity. Substitute parts must maintain the same inductance value, current rating compatibility, and surface mount package footprint while meeting modern RoHS3 compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ELL-VGG330M is determined by the following critical parameters:

• Inductance Value: Must be 33 µH with ±20% tolerance
• Current Rating: Minimum 340 mA continuous current capability
• Saturation Current (Isat): Minimum 450 mA
• DC Resistance (DCR): Must not exceed 1.33 Ohm to maintain circuit performance
• Shielding: Shielded or semi-shielded construction acceptable
• Package Footprint: Surface mount with 3.00mm x 3.00mm base dimensions and 1.50mm maximum height
• Compliance: ROHS3 compliant, MSL 1 rating

All three substitute parts meet these core substitution criteria while offering improved availability and active product status.

Parameter Comparison

Engineering Selection Recommendations

LQH3NPN330MMEL (Murata Electronics): This substitute offers superior current rating (460 mA) and significantly lower DC resistance (660 mOhm), providing improved thermal performance. Ferrite drum core construction with shielding matches the original design intent. ROHS3 compliant with unlimited MSL rating. Note that this part is discontinued at DiGi Electronics, which may affect long-term availability.

SD3114-330-R (Eaton - Electronics Division): This is the only active product with extended operating temperature range (-40°C ~ 125°C). DC resistance (1.23 Ohm) closely matches the original specification. Ferrite drum core with shielding provides electromagnetic compatibility. Footprint dimensions are marginally larger (3.10mm x 3.10mm) but remain compatible with standard 0.118" pitch layouts. RoHS compliant with MSL 1 rating.

SRN3015-330M (Bourns Inc.): This substitute provides the highest current rating (500 mA) and extended operating temperature range (-40°C ~ 125°C). Semi-shielded construction reduces EMI coupling compared to fully shielded designs. DC resistance (959 mOhm) is acceptable within circuit tolerance margins. ROHS3 compliant with unlimited MSL rating and active product status ensures long-term availability.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitutes directly in place of the ELL-VGG330M?

A: Yes, all three substitutes meet the core electrical and mechanical parameters required for direct replacement. The 33 µH inductance, ±20% tolerance, and surface mount footprint are identical or compatible across all options. Verify your circuit's current requirements and thermal constraints before final selection.

Q: What is the difference between shielded and semi-shielded inductors?

A: Shielded inductors (ELL-VGG330M, LQH3NPN330MMEL, SD3114-330-R) provide maximum electromagnetic field containment, reducing EMI coupling to adjacent components. Semi-shielded inductors (SRN3015-330M) offer partial shielding with lower profile and reduced cost. Semi-shielded construction is acceptable if EMI performance requirements are not critical.

Q: Why do the substitute parts have different DC resistance values?

A: DC resistance varies based on wire gauge, core material, and winding configuration. The LQH3NPN330MMEL (660 mOhm) and SRN3015-330M (959 mOhm) have lower resistance than the original (1.33 Ohm), which reduces power dissipation and improves efficiency. The SD3114-330-R (1.23 Ohm) closely matches the original specification.

Q: Are there any package footprint compatibility concerns?

A: The SD3114-330-R has a slightly larger footprint (3.10mm x 3.10mm) compared to the original and other substitutes (3.00mm x 3.00mm). This 0.10mm difference is negligible for most PCB layouts but should be verified if space constraints are critical. All parts maintain the same 1.50mm maximum height except SD3114-330-R at 1.40mm.

Q: Which substitute offers the best long-term availability?

A: SRN3015-330M (Bourns Inc.) and SD3114-330-R (Eaton) are both active products with confirmed inventory levels. LQH3NPN330MMEL is discontinued at DiGi Electronics, which may limit future sourcing options. For new designs requiring extended production runs, prioritize active product status.

Q: Do all substitutes meet RoHS3 compliance?

A: LQH3NPN330MMEL and SRN3015-330M are explicitly ROHS3 compliant. SD3114-330-R is RoHS compliant. All three meet modern environmental and regulatory requirements. MSL 1 rating across all parts indicates unlimited moisture sensitivity protection.
