Equivalent & Substitute Parts Reference for Vicor VI-22P-CY

Part Overview

The Vicor VI-22P-CY is an isolated DC-DC converter module designed for ITE (commercial) applications. It features one output channel with a regulated 13.8V output voltage and a maximum output current of 3.62A, supporting input voltages from 21V to 56V. The module delivers up to 50W of power, with 3 kV isolation and integrated OCP, OTP, OVP, SCP protections. It comes in a through-hole, full brick package sized 4.60" x 2.40" x 0.50" (116.8mm x 61.0mm x 12.7mm). The VI-22P-CY model is designated as Obsolete, requiring identification of alternatives to ensure design continuity and maintenance for assemblies using this part.

Key Parameters

Substitute Part Grouping Explanation

Substitute part selection is determined strictly by comparison of the following required parameters: manufacturer, series, product type, number of outputs, input voltage range, output voltage, output current rating, output power, isolation voltage, application, integrated features, efficiency, mounting type, package type, size/dimension, compliance status, operating temperature range, and inventory status. The substitute part must match all functional and mechanical parameters relevant for direct interchangeability within the DC-DC converter module category.

Parameter Comparison

Engineering Selection Recommendations

When selecting substitute parts for the Vicor VI-22P-CY, priority must be given to product status, inventory availability, and applicable compliance designations. The substitute part VI-22P-CY-B1 maintains active product status and shares identical electrical and most mechanical specifications with the main part number. Both models are RoHS non-compliant and REACH unaffected; therefore, compliance profiles are equivalent for regulatory and environmental requirements. Package dimensions differ in height, which must be verified for compatibility with mechanical constraints in the target assembly.

Frequently Asked Questions (FAQ)

Q: Are the electrical specifications matched between VI-22P-CY and VI-22P-CY-B1 for DC-DC converter applications?
A: Electrical specifications including input voltage range, output voltage, output current, power rating, isolation voltage, and integrated protection features are identical for both parts.

Q: Does the substitute part fit into the same mounting footprint as the original VI-22P-CY DC-DC converter module?
A: Both parts use the full brick package type with the same length and width; however, there is a difference in height (VI-22P-CY: 0.50", VI-22P-CY-B1: 1.07"). This must be considered for enclosure or cooling system compatibility.

Q: Are there differences in regulatory compliance between the main and substitute part numbers?
A: Both parts are RoHS non-compliant and carry REACH unaffected status; ECCN and HTSUS codes are matched.

Q: Is the substitute part, VI-22P-CY-B1, suitable for ongoing production in commercial ITE applications?
A: VI-22P-CY-B1 maintains active product status, matching all core parameters required for substitution except for mechanical height.

Q: What considerations must be addressed when replacing an obsolete Vicor VI-22P-CY converter with VI-22P-CY-B1?
A: All electrical parameters are matched; ensure the increased package height aligns with system design tolerances and applicable standards for mechanical integration.
