VI-24K-CX Equivalent & Substitute Parts Reference

Part Overview

The Vicor Corporation VI-24K-CX is a DC-DC converter classified as an isolated module with a single 40V output at up to 1.88A and a 75W power rating. It operates from a 55V to 100V DC input and provides a 3 kV isolation voltage. The product status is obsolete, making it necessary to identify substitute models that offer identical or equivalent electrical and mechanical characteristics for continued use in existing designs and maintenance.

Key Parameters

Substitute Part Grouping Explanation

The substitution logic is strictly based on equivalency in key electrical and mechanical parameters: input voltage range, output voltage, output current capability, power rating, isolation voltage, efficiency, operating temperature, features, mounting type, and package size. Only parts matching all these criteria are eligible as substitutes. The main parameter differences noted are confined to mechanical height within the full brick package format.

Parameter Comparison

Engineering Selection Recommendations

Product status and compliance are critical for component selection. The VI-24K-CX is obsolete, while the substitute VI-24K-CX-B1 has an active product status. Both are RoHS non-compliant and REACH unaffected. Mechanical height differs between the two, but both share the full brick format and primary electrical performance parameters.

Frequently Asked Questions (FAQ)

Q1: On what basis can VI-24K-CX-B1 be used as a substitute for VI-24K-CX?
A1: Substitution is based on matching input voltage range, output voltage, output current, power rating, isolation voltage, application type, protection features, efficiency, mounting type, package, and compliance statuses.

Q2: Are there any dimensional differences to consider when substituting VI-24K-CX with VI-24K-CX-B1?
A2: Both are full brick modules; however, the VI-24K-CX-B1 has increased height (1.07" compared to 0.50" for VI-24K-CX), which may affect mechanical fit in certain assemblies.

Q3: Do both parts meet the same regulatory and compliance listings?
A3: Both components are RoHS non-compliant and REACH unaffected.

Q4: Can the substitute part be used in applications originally designed for VI-24K-CX?
A4: From an electrical performance and protection features perspective, both parts are identical. Mechanical fit should be evaluated with reference to the height difference.

Q5: Does the change from obsolete to active status affect product availability?
A5: The substitute VI-24K-CX-B1 has an active product status, which supports ongoing procurement and maintenance needs.
