VI-22K-EW Equivalent & Substitute Parts Reference

Part Overview

The Vicor Corporation VI-22K-EW is a DC-DC converter from the VI-200™ (100W) series. This isolated module provides a single 40V output at up to 2.5A, supporting input voltages from 21V to 56V. With a maximum power rating of 100W and 3 kV isolation, it serves ITE (Commercial) applications and offers features including OCP, OTP, OVP, and SCP. The device is mounted in a full brick through-hole package. The product status is listed as obsolete, making it necessary for engineers to identify suitable alternative models, especially for ongoing manufacturing or maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected strictly based on the following matching key parameters: manufacturer, product series, type, number of outputs, input voltage range, output voltage, output current, power rating, isolation voltage, application, functional features, temperature range, efficiency, mounting type, and package. Only parts that align identically within these parameters qualify as valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

The main part VI-22K-EW is obsolete, while the substitute VI-22K-EW-B1 is active. Both parts share identical key electrical, mechanical, and regulatory parameters, including compliance and certifications. Both are RoHS non-compliant and REACH unaffected. Selection can be based on stock availability and active production status.

Frequently Asked Questions (FAQ)

Q1: What criteria are used for determining substitution compatibility in DC-DC converters?
A1: Substitution is determined by matching manufacturer, series, type, number of outputs, input voltage range, output voltage, output current, power rating, isolation voltage, application, features, operating temperature, efficiency, mounting type, and package.

Q2: Are there any compliance or regulatory considerations when selecting a substitute for VI-22K-EW?
A2: Both VI-22K-EW and VI-22K-EW-B1 are RoHS non-compliant and REACH unaffected, with the same ECCN and HTSUS classifications.

Q3: Is there a difference in form factor or mechanical dimensions between the main and substitute parts?
A3: Both parts use a full brick package with identical length and width. The height differs: VI-22K-EW is 0.50" high, while VI-22K-EW-B1 is 1.07" high.

Q4: Do the substitute parts maintain the same output power and electrical performance?
A4: Yes, both VI-22K-EW and VI-22K-EW-B1 provide 40V output at 2.5A with a maximum power of 100W, same input range, and identical electrical features.

Q5: Is there any change in mounting or application support between these parts?
A5: No, both are through-hole mounted and specified for ITE (Commercial) applications.
