Substitute Part Grouping Explanation
Substitution eligibility for the 252012CDMCCDS-2R2MC is determined by the following critical parameters:
Mandatory Matching Parameters:
- Inductance value: 2.2 µH
- Package / Case: 1008 (2520 Metric)
- Shielding type: Shielded
- Mounting type: Surface Mount
- Operating temperature range: -55°C ~ 125°C
- Tolerance: ±20%
Allowable Variation Parameters:
- Current Rating: May be equal to or greater than the original 2 A specification
- DC Resistance (DCR): May be equal to or lower than the original 113 mOhm maximum

The substitute part maintains active product status, ensuring ongoing availability and supply chain support. The substitute is supplied in Tape & Reel (TR) packaging, which is standard for production environments. The substitute part is RoHS3 compliant, supporting regulatory compliance requirements.
Frequently Asked Questions (FAQ)
Q: Can the 252012CDMCDDS-2R2MC be used as a direct replacement for the 252012CDMCCDS-2R2MC?
A: Yes. Both parts share identical inductance (2.2 µH), package (1008 / 2520 Metric), shielding, mounting type, and operating temperature range. The substitute provides higher current rating and lower DC resistance, making it functionally compatible and electrically superior.
Q: What is the difference in DC resistance between the original and substitute parts?
A: The original part specifies 113 mOhm Max, while the substitute specifies 82 mOhm Max. The lower resistance in the substitute reduces power dissipation and heat generation during operation.
Q: Are the physical dimensions identical between these two parts?
A: Yes. Both parts measure 0.098" L x 0.079" W (2.50mm x 2.00mm) with a maximum seated height of 0.047" (1.20mm). They are mechanically interchangeable on PCB layouts.
Q: What is the current rating difference, and does it affect substitution?
A: The original part is rated for 2 A continuous current, while the substitute is rated for 3 A. The higher rating in the substitute provides additional current capacity and design margin without affecting compatibility.
Q: Is the substitute part RoHS compliant?
A: Yes. The substitute part 252012CDMCDDS-2R2MC is RoHS3 compliant, supporting environmental and regulatory requirements.
Q: What packaging format is available for the substitute part?
A: The substitute part is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly and production environments.
