Substitute Part Grouping Explanation

Substitution eligibility for the 252012CDMCCDS-3R3MC is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 3.3 µH
• Inductance tolerance: ±20%
• Current rating: 1.5 A minimum
• Current saturation (Isat): 1.9 A minimum
• Shielding type: Shielded
• Package / Case: 1008 (2520 Metric)
• Mounting type: Surface Mount
• Operating temperature range: -55°C to 125°C minimum
• Inductance test frequency: 1 MHz

Acceptable Variation:

• DC Resistance (DCR): May vary within component design specifications, provided it does not exceed the maximum rating of 222 mOhm for the original part or the substitute part's specified maximum
• Core material: Metal or Metal Composite compositions are acceptable
• Product status: Active or discontinued parts are acceptable based on availability

The substitute part 252012CDMCDDS-3R3MC meets all mandatory matching parameters and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The 252012CDMCDDS-3R3MC is a direct functional equivalent to the 252012CDMCCDS-3R3MC. Selection between these parts should be based on the following engineering criteria:

Product Status Consideration: The substitute part 252012CDMCDDS-3R3MC carries an Active product status, whereas the main part is discontinued at DiGi Electronics. For new designs or ongoing production requiring component replenishment, the active substitute part is the appropriate selection to ensure continued supply chain availability.

Compliance and Certification: The substitute part 252012CDMCDDS-3R3MC is certified as ROHS3 Compliant. This certification status should be evaluated against project-specific regulatory requirements. The main part does not specify RoHS compliance status in the provided data.

Core Material Variation: The main part specifies a Metal core, while the substitute specifies a Metal Composite core. Both materials are acceptable within the shielded molded inductor category and maintain electrical performance equivalence at the specified inductance value, tolerance, current rating, and operating temperature range.

Electrical Performance: Both parts are rated for 1.5 A continuous current, operate across -55°C to 125°C, and are tested at 1 MHz. The inductance value of 3.3 µH with ±20% tolerance is identical. DC resistance specifications are not provided for the substitute part; however, the substitute part's active status and current availability indicate it meets the design requirements of the original specification.

Frequently Asked Questions (FAQ)

Q: Can the 252012CDMCDDS-3R3MC be used as a direct replacement for the 252012CDMCCDS-3R3MC in existing designs?

A: Yes. The substitute part meets all mandatory electrical and mechanical parameters: identical inductance (3.3 µH), tolerance (±20%), current rating (1.5 A), shielding type (Shielded), package (1008 / 2520 Metric), and operating temperature range (-55°C to 125°C). The parts are pin-compatible and footprint-compatible.

Q: What is the difference between the Metal core and Metal Composite core materials?

A: Both core materials are used in shielded molded inductors and are functionally equivalent for this application. The Metal Composite core in the substitute part maintains the same inductance value, tolerance, and electrical performance characteristics as the Metal core in the main part.

Q: Why is the substitute part listed as Active while the main part is Discontinued?

A: Product status reflects current manufacturer and distributor availability. The substitute part 252012CDMCDDS-3R3MC is currently in active production and available through distribution channels, making it the recommended selection for new orders and ongoing production requirements.

Q: Are there any compliance differences between the two parts?

A: The substitute part 252012CDMCDDS-3R3MC is certified as ROHS3 Compliant. The main part does not specify RoHS compliance in the provided documentation. Projects with RoHS compliance requirements should select the substitute part.

Q: Will the substitute part fit the same PCB footprint as the original part?

A: Yes. Both parts use the identical 1008 (2520 Metric) package with dimensions of 0.098" L x 0.079" W (2.50mm x 2.00mm) and maximum seated height of 0.047" (1.20mm). No PCB layout modifications are required.

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

A: Both parts carry a Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture control measures are required during storage, handling, or assembly.

Q: Is the DC resistance specification critical for substitution?

A: The main part specifies a maximum DC resistance of 222 mOhm. The substitute part does not provide a DC resistance specification in the available data. For applications where DC resistance is a critical design parameter, the substitute part's actual DCR should be obtained from the manufacturer's detailed datasheet before final selection.
