Equivalent & Substitute Parts Reference: Vicor VI-22J-CY

Part Overview

The Vicor Corporation VI-22J-CY is an isolated module DC-DC converter, designed to provide a regulated 36V/1.39A output from a 21V–56V input, with 50W power capability and 3 kV isolation. With integrated protection features and a full brick through-hole package, it is intended for ITE (Commercial) applications. The product is now categorized as "Obsolete," necessitating identification of equivalent or substitute models that can fulfill replacement or ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute selection for VI-22J-CY is based strictly on matching the following parameters: manufacturer, electrical ratings, function, package, compliance, and thermal/environmental ratings. Only substitute models with identical or compatible specifications for input/output voltage range, output current, power rating, isolation voltage, series, features, mounting type, and package/case dimensions (as listed) are considered valid equivalents.

Parameter Comparison

Engineering Selection Recommendations

Substitution from Vicor VI-22J-CY (Obsolete) to Vicor VI-22J-CY-B1 (Active) is supported by identical electrical performance, input/output ratings, feature set, compliance characteristics, and manufacturer. Both units are RoHS non-compliant and REACH unaffected. The only dimensional distinction concerns the physical height of the full brick package, which should be verified for mechanical fit in system assemblies where vertical clearance is critical. No technical variations are present in operational electrical parameters.

Frequently Asked Questions (FAQ)

Q: What electrical criteria must match between VI-22J-CY and its substitute?
A: Input voltage range, output voltage and current, power capability, isolation rating, features, efficiency, and application suitability must be identical across both parts, as specified.

Q: Are mechanical specifications relevant for substitution?
A: Yes. The full brick form factor and mounting type must match. The substitute VI-22J-CY-B1 has a greater package height (1.07" vs. 0.50"), requiring consideration for board or enclosure fit.

Q: Is regulatory compliance different between the original and substitute component?
A: No. Both units are RoHS non-compliant, REACH unaffected, and share ECCN and HTSUS codes.

Q: Can the substitute part be used in the same applications as the original?
A: Yes. Both are designed for ITE (Commercial) use and offer identical electrical features relevant to commercial power system applications.

Q: Do environmental ratings differ between the substitute and original?
A: No. Both parts are rated for -25°C ~ 85°C operating temperature range. The Moisture Sensitivity Level (MSL) is Not Applicable for both.

Q: Are there any feature differences between the substitute and original part?
A: No. Both provide overcurrent protection (OCP), overtemperature protection (OTP), overvoltage protection (OVP), and short circuit protection (SCP).

Q: Does the change in product status affect availability and procurement?
A: Yes. The original VI-22J-CY is obsolete, while the VI-22J-CY-B1 is active and available, supporting ongoing design-in and replacement activities.
