Substitute Part Grouping Explanation

The 78250JVC qualifies as a direct substitute for the 78250MVC based on the following critical parameters:

• Inductance: Both parts specify 2 mH, ensuring equivalent magnetic performance
• Isolation Voltage Rating: Both rated for 4 kVDC isolation
• Mounting Type: Both are surface mount components with identical package dimensions (0.354" L x 0.375" W x 0.260" H)
• Application Compatibility: Both are designated for use with MAX250 and MAX251 modules
• Regulatory Compliance: Both meet ROHS3 and REACH requirements
• Moisture Sensitivity: Both classified as MSL 1 (Unlimited)

The primary distinction is product status: the 78250JVC is Active, while the 78250MVC is Not For New Designs. The 78250JVC represents the current production equivalent within the 78250 series.

Frequently Asked Questions (FAQ)

Q: Can the 78250JVC be used as a direct replacement for the 78250MVC in existing designs?

A: Yes. The 78250JVC provides electrical and mechanical equivalence. Both parts share identical inductance (2 mH), isolation voltage (4 kVDC), surface mount package dimensions, and regulatory compliance status. No circuit or layout changes are required.

Q: What is the significance of the "Not For New Designs" status on the 78250MVC?

A: This designation indicates the part is in mature or end-of-life phase. Murata Power Solutions recommends using the Active 78250JVC for new applications and ongoing production to ensure long-term availability and manufacturer support.

Q: Are the package dimensions identical between these parts?

A: Yes. Both the 78250MVC and 78250JVC measure 0.354" L x 0.375" W x 0.260" H (9.00mm x 9.52mm x 6.60mm), ensuring identical PCB footprint compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, and classified as Moisture Sensitivity Level 1 (Unlimited).

Q: What applications are these transformers designed for?

A: Both parts are specified for use with Murata MAX250 and MAX251 power supply modules, providing 4 kVDC isolation in compact surface mount form factors.
