Equivalent & Substitute Parts for Vicor VI-22T-CY DC DC Converter
Part Overview
The Vicor VI-22T-CY is an obsolete isolated module DC-DC converter. It provides a single 6.5V output at up to 7.69A with wide input range (21V–56V), 50W power rating, 3kV isolation, and commercial ITE feature set. The series is VI-200™ (50W), with through-hole, full brick packaging. Due to its obsolete status and ongoing commercial demand, identifying compatible substitute models is essential to maintain supply and system continuity.

Engineering Selection Recommendations
The Vicor VI-22T-CY has an obsolete status and is RoHS non-compliant. The substitute part VI-22T-CY-B1 is active, matches all provided compliance, REACH, ECCN, and MSL parameters, and is also RoHS non-compliant. Both parts have identical electrical characteristics and are in the VI-200™ (50W) series. For direct substitution, verify mechanical compatibility where package height varies.
Frequently Asked Questions (FAQ)
Q: What criteria are used for selecting substitute DC-DC converters for VI-22T-CY?
A: Substitutes must match manufacturer, series, input and output voltage ranges, output current, power rating, isolation voltage, features, mounting type, operating temperature, and compliance parameters.
Q: Does the VI-22T-CY-B1 differ in electrical performance from VI-22T-CY?
A: All provided electrical and functional parameters are identical. The only provided difference is package height.
Q: Are there any compatibility considerations for mounting or fitting?
A: Both parts use the full brick through-hole package, but VI-22T-CY-B1 has a greater height (1.07" vs. 0.50"). Ensure sufficient clearance for the increased height.
Q: Are both parts RoHS compliant?
A: Both VI-22T-CY and VI-22T-CY-B1 are RoHS non-compliant according to provided parameters.
Q: Is there any difference in environmental certification or moisture sensitivity?
A: Both parts have identical REACH, ECCN, and MSL status. No differences are provided in these areas.
