Substitute Part Grouping Explanation
Substitute selection for DC DC converter modules in this category is strictly determined by identical input and output voltage ranges, output current and power ratings, isolation rating, feature set, operating temperature range, mechanical packaging, and compliance status. All substitute parts listed here maintain these specified parameters. Substitution is permitted only where every key electrical and mechanical parameter matches the main part.

Engineering Selection Recommendations
Selection should be based on product status, compliance, and certifications as specified. VI-22R-CY is obsolete; VI-22R-CY-B1 is active and is therefore suitable where continued availability is required and identical compliance profiles (RoHS non-compliance, REACH unaffected) are acceptable.
Frequently Asked Questions (FAQ)
Q1: What are the key criteria for selecting a substitute for Vicor VI-22R-CY?
A1: Substitution requires matching input voltage range, output voltage and current ratings, power capability, isolation voltage, package type and dimensions, feature set, operating temperature range, and compliance status.
Q2: Are there any differences in package dimensions between VI-22R-CY and VI-22R-CY-B1?
A2: VI-22R-CY-B1 maintains the same length and width but has a greater height (1.07" versus 0.50").
Q3: Is substitute part VI-22R-CY-B1 compatible with existing designs that use VI-22R-CY?
A3: Compatibility is determined by matching all the key electrical, mechanical, and compliance parameters. Only the height varies; confirm that height fits the allocated design envelope.
Q4: Do both parts share the same compliance status?
A4: Both VI-22R-CY and VI-22R-CY-B1 are RoHS non-compliant and REACH unaffected.
Q5: What applications are supported by both parts?
A5: Both are suitable for ITE (Commercial) use cases as specified.
