Engineering Selection Recommendations
The main part, Vicor VI-24J-CY, is obsolete. The substitute part, Vicor VI-24J-CY-B1, is active and retains all key functional and electrical parameters, compliance declarations, and application suitability. Both parts are RoHS non-compliant and have the same REACH and ECCN status. The principal consideration for substitution is the difference in component height, as the substitute is 1.07" high relative to the original's 0.50". Application-specific mechanical constraints must be verified using the exact dimensional data provided.
Frequently Asked Questions (FAQ)
Q1: What criteria are used for determining compatible substitute DC-DC converters in the VI-200™ (50W) series?
A1: Compatibility is determined by matching input voltage range, output voltage and current, output power, isolation voltage, protection features, environmental ratings, package type, and regulatory statuses.
Q2: Is the VI-24J-CY-B1 a form-fit substitute for VI-24J-CY?
A2: The VI-24J-CY-B1 matches all electrical and regulatory parameters. Its package footprint is the same; however, the component height is different (1.07" vs 0.50"). Dimensional compatibility for system integration should be checked using the dimensions provided.
Q3: Are there any differences in environmental or safety compliance between the two parts?
A3: Both parts are RoHS non-compliant, REACH unaffected, and share the same ECCN code and MSL status.
Q4: How should mounting and layout considerations be addressed when substituting these DC-DC converters?
A4: Both models use through-hole mounting and full brick packages, ensuring compatibility with standard full brick layouts. The difference in height can impact enclosure or airflow constraints.
Q5: Do the substitute and original parts share the same protection and performance features?
A5: Both models provide overcurrent, overtemperature, overvoltage, and short-circuit protection with equivalent input/output ratings and efficiency.
