Engineering Selection Recommendations

The 252012CDMCDDS-4R7MC serves as a direct functional substitute for the discontinued 252012CDMCCDS-4R7MC. Both components are manufactured by Sumida America Components Inc. and share identical electrical specifications for inductance, current rating, and operating temperature range. The substitute part maintains the same physical footprint and mounting characteristics, ensuring compatibility with existing PCB layouts.

The primary distinction between the two parts is product status: the main part is discontinued, while the substitute is currently active in production. The substitute part additionally carries ROHS3 compliance certification, providing enhanced environmental and regulatory alignment for new designs and procurement cycles.

Both components feature shielded molded construction with surface mount configuration in the 1008 (2520 Metric) package. The core material composition differs (Metal versus Metal Composite), but this variation does not affect the specified electrical performance parameters within the defined operating envelope.

Frequently Asked Questions (FAQ)

Q: Can the 252012CDMCDDS-4R7MC be used as a direct replacement for the 252012CDMCCDS-4R7MC in existing designs?

A: Yes. Both components share identical inductance values (4.7 µH), current ratings (1.4 A), operating temperature ranges (-55°C to 125°C), and package dimensions (1008 / 2520 Metric). The physical footprint and electrical performance are equivalent.

Q: What is the difference in core material between these two parts?

A: The main part uses a Metal core, while the substitute uses a Metal Composite core. Both configurations deliver the specified 4.7 µH inductance and support the 1.4 A current rating within the defined operating parameters.

Q: Why is the substitute part listed as active while the main part is discontinued?

A: The 252012CDMCDDS-4R7MC is currently in active production by Sumida America Components Inc., ensuring ongoing availability for procurement. The 252012CDMCCDS-4R7MC has been discontinued at DiGi Electronics, making the active substitute the recommended choice for new orders and design continuity.

Q: Are there any compliance differences between these parts?

A: The substitute part carries ROHS3 compliance certification. The main part's compliance status is not specified in the available documentation. For applications requiring specific regulatory certifications, the substitute part's ROHS3 status provides documented environmental compliance.

Q: Will the substitute part fit the same PCB layout?

A: Yes. Both components are housed in the 1008 (2520 Metric) package with identical dimensions: 0.098" L x 0.079" W (2.50mm x 2.00mm) and maximum seated height of 0.047" (1.20mm). No PCB redesign is required.

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

A: Both the main part and substitute are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
