Substitute Part Grouping Explanation

Substitution of the 252012CDMCCDS-R47MC is determined by strict equivalence across the following critical parameters:

Inductance Value and Tolerance: The substitute must maintain 470 nH inductance at ±20% tolerance, measured at 1 MHz test frequency.

Package and Mechanical Compatibility: The substitute must use the identical 1008 (2520 Metric) surface mount package with dimensions 0.098" L × 0.079" W (2.50 mm × 2.00 mm) and maximum seated height of 0.047" (1.20 mm).

Shielding Configuration: The substitute must be shielded to maintain electromagnetic isolation equivalent to the original design.

Electrical Performance Envelope: The substitute must operate within the -55°C to 125°C temperature range and maintain surface mount compatibility.

Current Handling Capability: While the original part specifies 4.8 A rated current, substitutes with equal or higher current ratings remain functionally compatible, provided all other parameters remain within specification.

The 252012CDMCDDS-R47MC meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 252012CDMCDDS-R47MC is a direct functional equivalent to the discontinued 252012CDMCCDS-R47MC. Both components share identical inductance values, package dimensions, and operating temperature specifications. The substitute offers improved electrical performance through lower DC resistance (21 mOhm versus 25 mOhm maximum) and higher current rating (6.1 A versus 4.8 A), providing enhanced thermal margin and reduced power dissipation in the same physical footprint.

The substitute part is currently in active production status with confirmed inventory availability (136,456 pieces), ensuring supply chain continuity. The 252012CDMCDDS-R47MC carries ROHS3 compliance certification, meeting modern regulatory requirements for electronic component manufacturing and end-of-life management.

The core material difference (Metal Composite in the substitute versus Metal in the original) does not affect functional compatibility, as both configurations maintain the specified inductance value, tolerance, and shielding characteristics within the defined operating envelope.

Frequently Asked Questions (FAQ)

Q: Can the 252012CDMCDDS-R47MC directly replace the 252012CDMCCDS-R47MC in existing designs?

A: Yes. Both components maintain 470 nH inductance at ±20% tolerance, identical package dimensions (1008 / 2520 Metric), and equivalent shielding. The substitute operates across the same -55°C to 125°C temperature range and maintains surface mount compatibility without PCB layout modifications.

Q: What is the significance of the lower DC resistance in the substitute part?

A: The substitute's 21 mOhm maximum DCR compared to the original's 25 mOhm maximum represents improved electrical efficiency. This reduction decreases resistive power loss (I²R) and thermal generation, providing operational margin within the same current rating envelope.

Q: Does the higher current rating of the substitute affect circuit operation?

A: No. The substitute's 6.1 A rating exceeds the original's 4.8 A specification, providing additional thermal headroom. Circuits designed for 4.8 A operation remain fully compatible, as the substitute accommodates this current level with improved performance characteristics.

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

A: No. Both components use identical 1008 (2520 Metric) surface mount packages with matching dimensions (0.098" L × 0.079" W / 2.50 mm × 2.00 mm) and maximum seated height (0.047" / 1.20 mm). No PCB footprint modifications are required.

Q: What is the impact of the core material change from Metal to Metal Composite?

A: The core material difference does not affect functional performance. Both configurations deliver the specified 470 nH inductance value, maintain ±20% tolerance, and preserve shielding effectiveness. The Metal Composite core in the substitute supports the improved electrical characteristics without altering circuit behavior.

Q: Is the substitute part RoHS compliant?

A: Yes. The 252012CDMCDDS-R47MC carries ROHS3 compliance certification. The original part's RoHS status was not specified in available documentation.

Q: What is the moisture sensitivity level for both parts?

A: Both components carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage, handling, or reflow processing.
