Vicor VI-22M-EX Equivalent & Substitute Parts Reference

Part Overview

The Vicor VI-22M-EX is an isolated DC-DC converter module with a single output of 10V at up to 7.5A, supporting a 21V to 56V input range and delivering up to 75W. It features overcurrent, overtemperature, overvoltage, and short-circuit protection and is primarily used in ITE (Commercial) applications. The VI-22M-EX is now classified as obsolete, making it necessary to identify alternative models strictly matching its key electrical, mechanical, and compliance specifications for direct substitution in existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Vicor VI-22M-EX is determined by strict matching of electrical and mechanical parameters, including: manufacturer, series, type, number of outputs, input voltage range, output voltage, maximum output current, power rating, isolation voltage, efficiency, operating temperature range, mounting type, package, dimensions, protection features, RoHS and REACH status, and product status. Only parts where all these specifications are directly equivalent are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

When selecting a substitute for the Vicor VI-22M-EX DC-DC converter module, evaluate product status, RoHS and REACH compliance, and inventory status. The VI-22M-EX is obsolete, while the VI-22M-EX-B1 is active and shares equivalent compliance and certification characteristics. Mechanical dimensions should be reviewed to ensure suitability for the application due to height variation.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for direct substitution of a DC-DC converter module?
A1: Key parameters include input voltage range, output voltage, maximum output current, power rating, isolation voltage, features, efficiency, operating temperature, package type, mounting, size, and compliance status (RoHS, REACH).

Q2: Are the VI-22M-EX and VI-22M-EX-B1 mechanically identical?
A2: Both parts share identical length and width, but the VI-22M-EX-B1 is taller (1.07" vs 0.50"). Mechanical fit must be confirmed for the intended application.

Q3: Do both parts have matching certifications?
A3: Both the VI-22M-EX and VI-22M-EX-B1 are RoHS non-compliant and REACH unaffected.

Q4: Is the VI-22M-EX-B1 a drop-in replacement for the VI-22M-EX?
A4: The VI-22M-EX-B1 matches all electrical, protection, and compliance parameters. Mechanical compatibility should be verified due to the difference in height.

Q5: Why is substitution necessary for the VI-22M-EX?
A5: Substitution is required due to the obsolete product status of the VI-22M-EX. Active equivalents with matching parameters are required for ongoing designs and maintenance.
