VI-22Z-IW Equivalent & Substitute Parts Reference

Part Overview

The Vicor Corporation VI-22Z-IW is an isolated module DC-DC converter providing a single 2V output at up to 20A with a wide input voltage range of 21V to 56V. Part of the VI-200™ (100W) series, the converter delivers up to 40W power and is designed for ITE (Commercial) applications. This model features overcurrent, overtemperature, overvoltage, and short circuit protection and achieves 90% efficiency. The VI-22Z-IW has an obsolete status, making it essential to identify suitable alternative models for ongoing designs or maintenance requiring this electrical and mechanical form factor.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are determined based on exact matching of key electrical parameters and mechanical specifications, as provided. The criteria for qualification as a substitute include: identical series, product type, number of outputs, input and output voltage ratings, output current, power rating, isolation voltage, application, protection features, operating temperature range, efficiency, mounting method, package type, and compliance status as specified (RoHS, REACH, ECCN, HTSUS). Only alternatives matching these parameters are qualified for consideration.

Parameter Comparison

Engineering Selection Recommendations

The VI-22Z-IW is obsolete; continued use in new designs or maintenance applications is not supported by ongoing production. The VI-22Z-IW-B1 provides an active alternative with identical electrical specifications and protection features. Both parts are RoHS non-compliant and have matching REACH status and ECCN classification. The primary mechanical difference is the height dimension; users must verify physical fit in the intended assembly based strictly on size. Selection of a substitute must ensure continued compliance with application RoHS requirements and dimensional allowances.

Frequently Asked Questions (FAQ)

Q1: What criteria determine if VI-22Z-IW-B1 is a valid substitute for VI-22Z-IW?
A1: Substitution is determined by identical voltage and current ratings, output configuration, series, efficiency, protection features, application classification, mounting type, package form factor, compliance status, and size parameters as provided.

Q2: Are the VI-22Z-IW and VI-22Z-IW-B1 mechanically interchangeable?
A2: Both use the Full Brick package with the same length and width. The VI-22Z-IW-B1 has a greater height (1.07" vs. 0.50"); confirm there are no height constraints in the targeted design location.

Q3: Are both parts RoHS compliant?
A3: Both VI-22Z-IW and VI-22Z-IW-B1 are RoHS non-compliant according to the provided data.

Q4: Is the electrical performance identical between VI-22Z-IW and VI-22Z-IW-B1?
A4: Both parts have 2V output at up to 20A, 21V–56V input range, 40W output power, and 3kV isolation.

Q5: Can VI-22Z-IW-B1 be used in commercial ITE applications?
A5: The application field for both parts specifies ITE (Commercial).

Q6: What is the key distinction between the two models for engineering selection?
A6: The primary distinction is product status (Obsolete for VI-22Z-IW, Active for VI-22Z-IW-B1) and package height. Verify assembly compatibility using the height value.
