Equivalent & Substitute Parts Reference for Vicor VI-22V-CY
Part Overview
The Vicor Corporation VI-22V-CY is an isolated DC-DC converter module, offering a single output of 5.8V at up to 8.62A with a 21V–56V input range and a power rating of 50W. It is classified as ITE (Commercial), features comprehensive protections (OCP, OTP, OVP, SCP), and is available in through-hole, full brick packaging. The product is currently listed as obsolete, making identification of substitute models necessary for ongoing design support and maintenance, particularly for applications requiring identical electrical, mechanical, and compliance characteristics.

Substitute Part Grouping Explanation
Substitution is determined strictly using core electrical, mechanical, and compliance parameters. The substitute part must match the following: input voltage range, output voltage and current, power rating, isolation voltage, operating temperature range, mounting style, package type, dimensions, and compliance status. These parameters ensure proper functionality, safety, and suitability for the same application and board footprint as the original part.

Engineering Selection Recommendations
Given the obsolete status of Vicor VI-22V-CY, selection of substitute models should be based on matching electrical performance, package dimensions, and compliance profile. VI-22V-CY-B1 provides identical input/output voltage, current, protection features, isolation voltage, operating temperature range, mounting type, and compliance status but differs in height dimension. Both are listed as RoHS non-compliant and REACH unaffected. Usage should be confirmed based on form factor compatibility.
Frequently Asked Questions (FAQ)
Q1: What parameters define compatibility for DC-DC converter substitutes in the VI-200™ (50W) series?
A1: Compatibility is determined by matching input voltage range, output voltage and current, power rating, isolation voltage, operating temperature, protection features, mounting type, package type, physical dimensions, and compliance status.
Q2: Are there differences in package dimensions between VI-22V-CY and VI-22V-CY-B1?
A2: Yes. VI-22V-CY is 0.50" height; VI-22V-CY-B1 is 1.07" height. Both share the same length and width.
Q3: Does the VI-22V-CY-B1 meet the same safety and compliance criteria as VI-22V-CY?
A3: Both parts are RoHS non-compliant and REACH unaffected; both provide 3 kV isolation and the same ECCN and HTSUS classifications.
Q4: Can VI-22V-CY-B1 be used as a direct replacement in an existing PCB design?
A4: Review physical envelope, especially the increased height of VI-22V-CY-B1, to ensure mechanical clearance and assembly compatibility.
Q5: Are operating conditions and feature sets identical between these two models?
A5: Yes. Input and output specifications, protections, efficiency, operating temperature range, and intended commercial application match exactly.
