Equivalent & Substitute Parts for Vicor VI-20V-CY

Part Overview

The Vicor VI-20V-CY is an isolated module DC DC converter featuring a single output of 5.8V at up to 8.62A, designed for ITE (commercial) applications. It is housed in a full brick through-hole package and delivers up to 50W of power with 3 kV isolation. As this product is listed with an "Obsolete" status, sourcing alternative models with strictly matching electrical and mechanical specifications is necessary for continued system function and supply assurance.

Key Parameters

Substitute Part Grouping Explanation

Substitution grouping is based strictly on identical key parameters required for compatible performance: input voltage range, output voltage, output current, power rating, isolation voltage, number of outputs, features, operating temperature, efficiency, mounting type, case style, and application category. Substitute models are selected only if all these parameters explicitly match those of the main part.

Parameter Comparison

Engineering Selection Recommendations

Based on the product status, the VI-20V-CY is obsolete while the VI-20V-CY-F1 is active. Both parts are RoHS non-compliant and REACH unaffected. The substitute VI-20V-CY-F1 matches all provided electrical, mechanical, and compliance parameters. Selection between these parts can be made with assurance of identical functional, environmental, and regulatory characteristics, subject to mechanical size considerations noted in the provided dimensions.

Frequently Asked Questions (FAQ)

Which parameters must match for substitution of DC DC converters like the VI-20V-CY?
Only the explicitly provided parameters can be used for substitution. These include input voltage range, output voltage, output current, power rating, isolation voltage, number of outputs, features, operating temperature, efficiency, mounting type, package style, dimensions, application category, and compliance status.

What compliance and certification factors should be considered when selecting substitutes?
Selections must be based on the provided RoHS status, REACH status, ECCN, and HTSUS codes. For VI-20V-CY and VI-20V-CY-F1, both parts are RoHS non-compliant and REACH unaffected.

Are mechanical package differences relevant for substitution?
Mechanical dimensions and mounting type must match or be accommodated within the system. Both substitutes are full brick and through-hole, but dimensions differ (VI-20V-CY: 4.60" x 2.40" x 0.50"; VI-20V-CY-F1: 4.60" x 1.86" x 0.79"). Verification of compatibility with system requirements based strictly on provided dimensions is necessary.

Does the operational temperature range affect substitutability?
Both parts share the same operating temperature range, -25°C ~ 85°C, allowing for direct substitution within this parameter.

Is the substitute part VI-20V-CY-F1 suitable as a drop-in replacement for VI-20V-CY?
VI-20V-CY-F1 is suitable as a substitute based strictly on matching electrical, mechanical, and compliance characteristics provided. System fit should be evaluated against the listed size/dimension parameters.
