ELL-4GG330M Equivalent & Substitute Parts

Part Overview

The Panasonic ELL-4GG330M is a 33 µH shielded wirewound inductor rated for 400 mA with 980mOhm DC resistance, designed for surface mount applications in nonstandard package configurations. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. Substitute parts must maintain the same inductance value, tolerance, shielding characteristics, and compatible current ratings to ensure functional equivalence in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELL-4GG330M are qualified based on the following electrical and mechanical parameters:

Primary Matching Criteria:

• Inductance value: 33 µH (exact match required)
• Tolerance: ±20% (standard tolerance maintained)
• Shielding: Shielded configuration
• Mounting type: Surface mount
• Test frequency: 100 kHz

Secondary Compatibility Parameters:

• Current rating: Minimum 400 mA (equal or higher acceptable)
• DC resistance: Within reasonable operational range (628mOhm to 980mOhm)
• Saturation current: Minimum 450mA (equal or higher acceptable)
• Package dimensions: Nonstandard, with height compatibility for PCB assembly
• RoHS and MSL compliance: ROHS3 compliant, MSL 1 rating

All four substitute parts meet these criteria with active product status and confirmed inventory availability.

Parameter Comparison

Engineering Selection Recommendations

CDRH3D16/HPNP-330MC (Sumida America Components Inc.)

This substitute provides the closest dimensional match to the ELL-4GG330M with identical 3.80mm x 3.80mm footprint. DC resistance of 870mOhm is within acceptable operational range. Current rating of 410 mA exceeds the minimum 400 mA requirement. ROHS3 compliance and MSL 1 rating match the original specification. Highest inventory availability (4030 pcs) ensures supply continuity. Recommended as primary substitute for direct replacement applications.

LMLP04A4M330CTAS (KYOCERA AVX)

This part offers the lowest profile height at 1.20mm, beneficial for space-constrained PCB designs. DC resistance of 810mOhm and current rating of 420 mA provide adequate performance margins. Extended operating temperature range to 125°C offers enhanced thermal capability. ROHS3 compliance and MSL 1 rating confirmed. Suitable for applications requiring compact vertical clearance.

VLCF4020T-330MR47 (TDK Corporation)

This substitute features the lowest DC resistance at 628mOhm, reducing power dissipation in the inductor. Current rating of 470 mA provides the highest performance margin among all substitutes. Drum core wirewound construction matches the original design approach. ROHS3 compliance and REACH unaffected status confirmed. Recommended for applications prioritizing efficiency and thermal performance.

CDPH40D18NP-330MC (Sumida America Components Inc.)

This part provides the highest saturation current rating at 640mA, offering maximum current handling capability. Drum core wirewound construction aligns with original design. Slightly larger footprint (4.20mm x 4.20mm) requires PCB layout verification. Suitable for high-current applications where saturation margin is critical.

Frequently Asked Questions (FAQ)

Q: Can I use any of these substitute parts interchangeably with the ELL-4GG330M?

A: All four substitute parts maintain the same 33 µH inductance value, ±20% tolerance, and shielded configuration. However, dimensional differences require PCB layout verification. CDRH3D16/HPNP-330MC provides the closest footprint match (3.80mm x 3.80mm). Verify height clearance for your specific assembly, as substitutes range from 1.20mm to 2.00mm.

Q: What is the significance of DC resistance differences among these parts?

A: DC resistance values range from 628mOhm (VLCF4020T-330MR47) to 980mOhm (ELL-4GG330M). Lower DCR reduces power dissipation and heat generation. Selection depends on circuit current levels and thermal constraints. All values remain within acceptable operational ranges for 33 µH inductors in this current class.

Q: Are all substitutes RoHS3 compliant?

A: CDRH3D16/HPNP-330MC, LMLP04A4M330CTAS, and VLCF4020T-330MR47 are confirmed ROHS3 compliant. CDPH40D18NP-330MC RoHS status is not specified in available data. Verify compliance documentation with supplier if RoHS certification is required for your application.

Q: What packaging formats are available for these substitutes?

A: CDPH40D18NP-330MC, CDRH3D16/HPNP-330MC, and LMLP04A4M330CTAS are supplied in Tape & Reel (TR) format. VLCF4020T-330MR47 is available in Cut Tape (CT) and Digi-Reel® format. Confirm packaging compatibility with your assembly equipment and procurement requirements.

Q: Which substitute offers the best thermal performance?

A: VLCF4020T-330MR47 provides the lowest DC resistance (628mOhm), minimizing resistive heating. LMLP04A4M330CTAS offers the widest operating temperature range (-40°C to 125°C), supporting higher ambient conditions. Selection depends on whether priority is reducing component heating or operating in elevated temperature environments.

Q: Is the height difference between substitutes significant for my design?

A: Height variations range from 1.20mm (LMLP04A4M330CTAS) to 2.00mm (CDPH40D18NP-330MC and VLCF4020T-330MR47). Verify clearance above the inductor for your specific PCB assembly. CDRH3D16/HPNP-330MC at 1.80mm and LMLP04A4M330CTAS at 1.20mm offer lower-profile options if space is constrained.
