ELL-VFG330MC Equivalent & Substitute Parts

Part Overview

The ELL-VFG330MC is a 33 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 330 mA continuous current with 1.16Ohm DC resistance. This surface mount component operates at 100 kHz test frequency and is housed in a 3.00mm x 3.00mm nonstandard package with 1.20mm maximum seated height.

The product is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELL-VFG330MC are qualified based on the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Inductance value: 33 µH (exact match required)
• Inductance tolerance: ±20% (matching specification)
• Current rating: minimum 330 mA continuous
• DC resistance: within acceptable operating range for the application
• Shielding: shielded construction required
• Test frequency: 100 kHz

Mechanical Compatibility Criteria:

• Mounting type: Surface Mount
• Package footprint: 3.00mm x 3.00mm nominal dimensions
• Height: compatible with 1.20mm seated height constraint
• Core type: wirewound construction

Compliance Criteria:

• RoHS3 compliance required
• Active or current product status preferred for long-term availability

Two substitute parts meet these criteria: ASPI-0312FS-330M-T2 (Abracon LLC) and SD3114-330-R (Eaton - Electronics Division).

Parameter Comparison

Engineering Selection Recommendations

ASPI-0312FS-330M-T2 (Abracon LLC) is the primary substitute for ELL-VFG330MC. This part maintains identical inductance, tolerance, current rating, and package footprint dimensions. The DC resistance is lower at 1.03Ohm compared to 1.16Ohm, resulting in reduced power dissipation. Saturation current is higher at 310 mA versus 280 mA, providing improved margin. The part is active status with ROHS3 compliance and ferrite core construction. Operating temperature range is -25°C to 120°C. Packaging is Tape & Reel format with 835 units in stock.

SD3114-330-R (Eaton - Electronics Division) is an alternative substitute. This part matches the 33 µH inductance and ±20% tolerance specification. Current rating is higher at 350 mA with saturation current of 440 mA, providing additional headroom. DC resistance is 1.23Ohm, slightly higher than the original. Physical dimensions are 3.10mm x 3.10mm with 1.40mm seated height, representing a minor footprint increase. The part is active status with RoHS compliance and ferrite core construction. Operating temperature range extends to -40°C to 125°C. Packaging is Tape & Reel format with 1153 units in stock.

Selection between the two substitutes depends on specific application constraints: ASPI-0312FS-330M-T2 offers exact footprint match and lower DCR, while SD3114-330-R provides higher current ratings and extended temperature range at the cost of slightly larger dimensions.

Frequently Asked Questions (FAQ)

Q: Can ASPI-0312FS-330M-T2 be used as a direct replacement for ELL-VFG330MC?

A: Yes. Both parts share identical inductance (33 µH), tolerance (±20%), current rating (330 mA), and package footprint (3.00mm x 3.00mm x 1.20mm). The ASPI-0312FS-330M-T2 features lower DC resistance (1.03Ohm vs 1.16Ohm) and higher saturation current (310 mA vs 280 mA), making it functionally compatible for direct substitution.

Q: What are the differences between ASPI-0312FS-330M-T2 and SD3114-330-R?

A: Both are 33 µH shielded wirewound inductors with ±20% tolerance. ASPI-0312FS-330M-T2 maintains the exact 3.00mm x 3.00mm footprint and 1.20mm height of the original part. SD3114-330-R has a slightly larger footprint (3.10mm x 3.10mm) and height (1.40mm), but offers higher current rating (350 mA) and saturation current (440 mA). SD3114-330-R also provides extended operating temperature range (-40°C to 125°C vs -25°C to 120°C).

Q: Is the ferrite core material in the substitute parts compatible with the original design?

A: The original ELL-VFG330MC core material is not specified in the datasheet. Both substitute parts use ferrite core construction with identical inductance and tolerance specifications at 100 kHz test frequency. Ferrite core wirewound inductors are standard for this inductance and current rating class.

Q: Can SD3114-330-R be used if PCB space is limited?

A: SD3114-330-R has a larger footprint (3.10mm x 3.10mm) and height (1.40mm) compared to the original (3.00mm x 3.00mm x 1.20mm). If PCB layout constraints require the exact original dimensions, ASPI-0312FS-330M-T2 is the appropriate choice. If space permits the additional 0.10mm in length and width and 0.20mm in height, SD3114-330-R is viable.

Q: What is the significance of the DC resistance difference?

A: ELL-VFG330MC has 1.16Ohm DCR, ASPI-0312FS-330M-T2 has 1.03Ohm, and SD3114-330-R has 1.23Ohm. Lower DCR reduces power dissipation and heat generation. Higher DCR increases power loss. The differences are within typical design margins for 33 µH inductors at 330 mA rating. Application thermal requirements determine acceptability.

Q: Are both substitute parts RoHS compliant?

A: Yes. ASPI-0312FS-330M-T2 is ROHS3 compliant. SD3114-330-R is RoHS compliant. Both meet environmental compliance requirements for current manufacturing standards.
