Key Parameters

Substitute Part Grouping Explanation

Substitution of the 0520CDMCDS-2R2MC is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 2.2 µH at 100 kHz test frequency
• Inductance tolerance: ±20%
• Shielding requirement: Shielded construction
• Mounting type: Surface Mount
• Physical footprint compatibility: Dimensions within acceptable tolerance for PCB layout

Acceptable Variation Parameters:

• Current rating: Substitute must equal or exceed 4.1 A continuous rating
• Saturation current (Isat): Substitute must equal or exceed 6 A
• DC resistance (DCR): Substitute may exceed 30mOhm provided circuit design accommodates increased losses
• Operating temperature range: Substitute must cover or exceed -40°C to 105°C
• Regulatory compliance: RoHS3 compliance required

The MGV05022R2M-10 from Laird-Signal Integrity Products meets all critical parameters and is classified as an active product, providing long-term availability assurance.

Engineering Selection Recommendations

The MGV05022R2M-10 is the qualified substitute for the obsolete 0520CDMCDS-2R2MC based on the following engineering criteria:

Electrical Compatibility: Both inductors provide 2.2 µH inductance at ±20% tolerance with identical shielding. The MGV05022R2M-10 exceeds the continuous current rating (4.2 A vs. 4.1 A) and saturation current (12.5 A vs. 6 A), providing improved performance margin in the target application.

Thermal Performance: The substitute operates across -40°C to 125°C, extending the upper temperature limit by 20°C compared to the original part, ensuring compatibility with designs requiring enhanced thermal headroom.

Regulatory Compliance: Both components are RoHS3 compliant and carry EAR99 ECCN classification, maintaining regulatory alignment for export and environmental requirements.

Physical Integration: Dimensional compatibility is confirmed with matched length (5.50 mm) and width differential of 0.10 mm (5.20 mm vs. 5.10 mm). Height increase of 0.30 mm (2.00 mm to 2.30 mm) requires PCB layout verification to confirm clearance in constrained vertical spaces.

DC Resistance Consideration: The substitute exhibits higher DC resistance (50.1 mOhm vs. 30 mOhm), resulting in increased power dissipation. Circuit thermal analysis is required to confirm acceptable performance in applications sensitive to inductor losses.

Product Status Advantage: The MGV05022R2M-10 is classified as active, ensuring long-term availability and supply chain continuity compared to the obsolete 0520CDMCDS-2R2MC.

Frequently Asked Questions (FAQ)

Q: Can the MGV05022R2M-10 be used as a direct replacement for the 0520CDMCDS-2R2MC?

A: The MGV05022R2M-10 is electrically compatible for applications requiring 2.2 µH inductance at 4.1 A or higher. Physical layout verification is required due to 0.30 mm height difference and 0.10 mm width variation. DC resistance increase from 30 mOhm to 50.1 mOhm must be evaluated for thermal impact in the specific circuit.

Q: What is the primary reason for substitution?

A: The 0520CDMCDS-2R2MC is classified as obsolete. The MGV05022R2M-10 is an active product from Laird-Signal Integrity Products, providing assured long-term availability and supply continuity.

Q: Are there any performance differences between these inductors?

A: Both inductors provide identical inductance (2.2 µH) and tolerance (±20%). The MGV05022R2M-10 offers higher current ratings (4.2 A vs. 4.1 A continuous; 12.5 A vs. 6 A saturation) and extended temperature range (-40 to 125°C vs. -40 to 105°C). The substitute exhibits higher DC resistance (50.1 mOhm vs. 30 mOhm), increasing power dissipation by approximately 67%.

Q: What packaging differences exist?

A: The 0520CDMCDS-2R2MC packaging is listed as nonstandard. The MGV05022R2M-10 is supplied in Tape & Reel (TR) format, providing standard automated assembly compatibility.

Q: Is PCB layout modification required?

A: Height increase of 0.30 mm (2.00 mm to 2.30 mm) requires clearance verification in designs with tight vertical constraints. Width difference of 0.10 mm (5.20 mm to 5.10 mm) is negligible for standard PCB footprints. Thermal layout review is recommended due to increased DC resistance.

Q: Are both parts RoHS compliant?

A: Both the 0520CDMCDS-2R2MC and MGV05022R2M-10 are RoHS3 compliant, maintaining regulatory alignment for environmental and export requirements.

Q: What is the impact of higher DC resistance on circuit performance?

A: The 50.1 mOhm DCR of the MGV05022R2M-10 compared to 30 mOhm of the original part results in increased resistive losses. Power dissipation increases proportionally with current squared. Circuit thermal analysis is required to confirm acceptable operating conditions, particularly in high-current or thermally constrained applications.
