0420CDMCDS-2R2MC Equivalent & Substitute Parts

Part Overview

The 0420CDMCDS-2R2MC is a 2.2 µH shielded wirewound inductor manufactured by Sumida America Components Inc., rated for 4.7 A continuous current with 35mOhm DC resistance. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design support and procurement continuity. Substitute parts must maintain electrical performance within the specified inductance, current rating, and DC resistance parameters while accommodating mechanical and thermal requirements of the application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 0420CDMCDS-2R2MC is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Inductance value: 2.2 µH (±20% tolerance acceptable)
• Continuous current rating: minimum 4.7 A
• DC resistance: maximum 35mOhm preferred; values up to 58mOhm acceptable with thermal analysis
• Saturation current (Isat): minimum 4.5 A
• Shielding: required (shielded configuration)

Mechanical & Environmental Criteria:

• Mounting type: Surface Mount (SMD)
• Operating temperature range: minimum -40°C to 105°C
• RoHS3 compliance: required
• Moisture Sensitivity Level (MSL): 1 or Not Applicable acceptable

Package Considerations:

• Primary package: 1816 (4540 Metric) or equivalent nonstandard packages with compatible footprint dimensions
• Supplier packaging: Tape & Reel (TR) acceptable for production environments

Two active substitute parts meet these criteria with documented electrical and mechanical compatibility.

Engineering Selection Recommendations

MPLCG0530L2R2 (KEMET) - Primary Substitute

The MPLCG0530L2R2 is the preferred substitute for the 0420CDMCDS-2R2MC. This part maintains active product status with ROHS3 compliance and extended operating temperature range (-40°C to 125°C). The current rating of 4.5 A is marginally lower than the original 4.7 A specification; however, saturation current (Isat) of 5.0 A and DC resistance of 36.4 mOhm Max provide equivalent electrical performance. The drum core, wirewound construction with metal composite core delivers low DCR and low loss characteristics. Mechanical footprint is larger (5.50mm x 4.10mm vs. 4.50mm x 4.10mm) and seated height is 3.00mm versus 2.00mm; PCB layout verification is required. MSL rating of 1 (Unlimited) matches the original part.

MGV04022R2M-10 (Laird-Signal Integrity Products) - Secondary Substitute

The MGV04022R2M-10 is an active alternative with ROHS3 compliance and extended operating temperature range (-40°C to 125°C). Continuous current rating of 3.0 A is significantly lower than the original 4.7 A specification and does not meet the primary electrical requirement. This part is suitable only for applications where actual operating current does not exceed 3.0 A. DC resistance of 58 mOhm Max is elevated relative to the original 35 mOhm specification, resulting in increased power dissipation. Mechanical footprint matches the original (4.50mm x 4.10mm); seated height of 2.30mm is compatible with space constraints. MSL rating is Not Applicable. Use of this part requires thermal and current load analysis to confirm suitability.

Frequently Asked Questions (FAQ)

Q: Can the MGV04022R2M-10 be used as a direct replacement for the 0420CDMCDS-2R2MC?

A: No. The MGV04022R2M-10 has a continuous current rating of 3.0 A, which is below the original part's 4.7 A specification. This part is suitable only if the actual circuit operating current does not exceed 3.0 A. The elevated DC resistance (58 mOhm Max vs. 35 mOhm) also increases power dissipation. Electrical load analysis is required before selection.

Q: What are the mechanical compatibility considerations for the MPLCG0530L2R2?

A: The MPLCG0530L2R2 has a larger footprint (5.50mm x 5.00mm vs. 4.50mm x 4.10mm) and greater seated height (3.00mm vs. 2.00mm). PCB layout must be verified to confirm adequate space for component placement and clearance from adjacent components. The nonstandard package designation requires confirmation of mechanical fit within the target assembly.

Q: Are both substitute parts RoHS3 compliant?

A: Yes. Both the MPLCG0530L2R2 and MGV04022R2M-10 are ROHS3 compliant, matching the compliance status of the original 0420CDMCDS-2R2MC.

Q: What is the impact of higher DC resistance in the MGV04022R2M-10?

A: The MGV04022R2M-10 has a DC resistance of 58 mOhm Max compared to 35 mOhm in the original part. At the original 4.7 A operating current, this results in additional power dissipation of approximately 0.65 W (I²R loss difference). Thermal management and circuit performance must be evaluated before substitution.

Q: Can the MPLCG0530L2R2 operate at the full 4.7 A rating of the original part?

A: The MPLCG0530L2R2 has a continuous current rating of 4.5 A, which is 0.2 A below the original 4.7 A specification. Saturation current (Isat) is 5.0 A. Operation at 4.7 A approaches saturation and may result in inductance degradation and increased core losses. Operation at or below 4.5 A is recommended.

Q: What is the difference between the original 1816 package and the nonstandard packages of the substitutes?

A: The original 0420CDMCDS-2R2MC uses the 1816 (4540 Metric) standard package designation. The MPLCG0530L2R2 uses a nonstandard package with dimensions 5.50mm x 5.00mm x 3.00mm (height). The MGV04022R2M-10 uses a nonstandard package with dimensions 4.50mm x 4.10mm x 2.30mm (height). Nonstandard packages require explicit PCB footprint verification and may not be interchangeable without layout modification.

Q: Are there temperature range differences between the original and substitute parts?

A: Yes. The original 0420CDMCDS-2R2MC operates from -40°C to 105°C. Both substitutes extend the upper temperature limit to 125°C. If the application requires operation above 105°C, the substitutes provide extended thermal capability. If operation is limited to 105°C or below, both substitutes remain compatible.
