Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified by matching specified functional and mechanical parameters. For isolated module DC-DC converters, key substitution criteria include: input voltage range, output voltage and current ratings, power capacity, isolation voltage, mounting type, package/case, efficiency, operating temperature range, and compliance designations. Substitutes must align precisely across these attributes to ensure electrical and mechanical compatibility for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

Selection between VI-J2M-CY and VI-J2M-CY-B1 is determined primarily by product status and compliance. The VI-J2M-CY is obsolete, and the VI-J2M-CY-B1 is active. Both models maintain identical key electrical and mechanical specifications, including RoHS non-compliance and REACH unaffected status. The substitute part provides continued availability within the same compliance framework and certifications relevant for inventory and supported applications.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting VI-J2M-CY in a design?
A1: Substitution requires matching input voltage range (21V–56V), output voltage (10V), output current (5A), power rating (50W), isolation voltage (3kV), mounting type (Through Hole), package/case (Half Brick), features, efficiency, and compliance status.

Q2: Is the package size of VI-J2M-CY-B1 fully interchangeable with VI-J2M-CY?
A2: The package/case is Half Brick for both, but mechanical dimensions differ. Review physical compatibility with existing layouts.

Q3: Are there differences in compliance designations between the parts?
A3: Both models are RoHS non-compliant and REACH unaffected. Selection will not impact environmental certification status for the listed criteria.

Q4: Can substitute parts be used in identical ITE (Commercial) applications?
A4: Both are specified for ITE (Commercial) applications under identical electrical and mechanical parameters. Compatibility is maintained for those criteria.

Q5: What should be considered regarding product status when selecting a substitute?
A5: The obsolete status of VI-J2M-CY requires transition to the active VI-J2M-CY-B1 to maintain availability and support for ongoing production.

Q6: Do features like OCP (Overcurrent Protection) and SCP (Short Circuit Protection) remain consistent?
A6: Both models specify OCP and SCP, ensuring identical feature sets.
