ELL-4GG220M Equivalent & Substitute Parts

Part Overview

The ELL-4GG220M is a 22 µH shielded wirewound inductor manufactured by Panasonic Electronic Components, rated for 500 mA continuous current with 640mOhm DC resistance. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. Substitute parts must maintain the 22 µH inductance specification and surface mount compatibility while meeting or exceeding the electrical performance parameters of the original design.

Substitute Part Grouping Explanation

Substitution eligibility for the ELL-4GG220M is determined by the following mandatory parameters:

Inductance value of 22 µH at 100 kHz test frequency
Tolerance of ±20%
Surface mount configuration with nonstandard package footprint
Current rating capability of 500 mA minimum
Shielded construction to minimize electromagnetic interference
Physical dimensions compatible with 3.80mm x 3.80mm footprint
ROHS3 compliance and MSL 1 rating

The three substitute parts listed below satisfy these core electrical and mechanical requirements while offering active product status and improved availability compared to the obsolete ELL-4GG220M.

Engineering Selection Recommendations

74404043220A (Würth Elektronik WE-LQS Series)

This part offers the highest current rating at 1.11 A and the lowest DC resistance at 200mOhm, providing superior thermal performance and reduced power dissipation. The AEC-Q200 automotive qualification and extended operating temperature range of -40°C to 125°C support demanding applications. The 4.00mm x 4.00mm footprint requires PCB layout verification for compatibility with the original 3.80mm x 3.80mm design. Semi-shielded construction may require electromagnetic compatibility assessment in noise-sensitive circuits.

CDH38D11SLDNP-220MC (Sumida CDH38D11/SLD Series)

This unshielded inductor maintains the original 3.80mm x 3.80mm footprint and offers the lowest profile at 1.20mm height. Current rating of 490 mA meets the 500 mA requirement with minimal margin. DC resistance of 730mOhm maximum exceeds the original specification. Unshielded construction is suitable only for applications where electromagnetic interference is not a design constraint.

CDRH3D16/HPNP-220MC (Sumida CDRH3D16/HP Series)

This shielded inductor provides the closest electrical match to the ELL-4GG220M with 520 mA current rating, 610mOhm maximum DC resistance, and identical 3.80mm x 3.80mm footprint. Shielded construction preserves the original electromagnetic performance characteristics. Height of 1.80mm requires PCB clearance verification. Operating temperature range of -40°C to 105°C is suitable for standard industrial applications.

Frequently Asked Questions (FAQ)

Q: Can the 74404043220A substitute for the ELL-4GG220M in a space-constrained design?

A: The 74404043220A has a 4.00mm x 4.00mm footprint compared to the original 3.80mm x 3.80mm, and a height of 2.50mm versus 1.40mm. PCB layout must be verified to confirm adequate clearance before implementation.

Q: What is the impact of using an unshielded inductor (CDH38D11SLDNP-220MC) in place of the shielded ELL-4GG220M?

A: Unshielded construction increases radiated electromagnetic emissions and susceptibility to external magnetic fields. This substitution is acceptable only in applications where EMI/RFI performance is not specified or where the circuit operates in electromagnetically benign environments.

Q: Which substitute part has the best thermal performance?

A: The 74404043220A offers the lowest DC resistance at 200mOhm, resulting in the lowest I²R power dissipation at rated current. This part generates approximately 122 mW at 1.11 A compared to 160 mW for the ELL-4GG220M at 500 mA.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all three substitute parts carry ROHS3 compliance certification and MSL 1 (Unlimited) moisture sensitivity ratings, matching the environmental qualification of the original ELL-4GG220M.

Q: What is the saturation current consideration for circuit design?

A: The ELL-4GG220M has saturation current of 600mA. The 74404043220A (700mA), CDRH3D16/HPNP-220MC (550mA), and CDH38D11SLDNP-220MC (440mA) exhibit different saturation characteristics. Designs operating near maximum current must account for inductance degradation at saturation.

Q: Can the CDRH3D16/HPNP-220MC be used as a direct replacement without PCB modification?

A: Yes. The CDRH3D16/HPNP-220MC maintains the 3.80mm x 3.80mm footprint and shielded construction of the original. Height difference of 0.40mm (1.80mm versus 1.40mm) requires clearance verification but does not necessitate footprint redesign.
