Equivalent & Substitute Parts for Vicor VI-B6Z-CW DC-DC Converter

Part Overview

Vicor Corporation’s VI-B6Z-CW is a DC-DC converter from the VI-200™ (100W) series. This isolated module features a single output delivering 2V at up to 20A, with an input voltage range of 200V to 400V. It provides 40W output power and is designed for applications in ITE (Commercial) environments, with features including Over Current Protection (OCP), Over Temperature Protection (OTP), Over Voltage Protection (OVP), and Short Circuit Protection (SCP).

The VI-B6Z-CW model is currently marked as “Obsolete.” Users requiring ongoing production support or direct replacements must evaluate alternative parts that match all specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are determined by matching all key electrical and mechanical parameters to maintain compatibility. The following parameters are mandatory for substitution in the DC-DC converter product category: part series, input and output voltage range, output current, power rating, isolation voltage, protection features, operating temperature, mounting type, package/case, and overall dimensions. Regulatory statuses such as RoHS and REACH, as well as product status (active or obsolete), are included for compliance and sourcing considerations.

Parameter Comparison

Engineering Selection Recommendations

The main part, VI-B6Z-CW, is marked as obsolete. For continued production or maintenance applications requiring equivalent circuit and mechanical characteristics, VI-B6Z-CW-B1 provides a direct substitute from the same manufacturer, series, and specification set. Both variants are RoHS non-compliant and REACH unaffected, with identical electrical parameters and mounting options. Dimensional variation is limited to package height (0.50" for VI-B6Z-CW versus 1.07" for VI-B6Z-CW-B1). ECCN and HTSUS codes remain unchanged across parts.

Frequently Asked Questions (FAQ)

Q1: What are the required matching parameters for substituting Vicor VI-B6Z-CW in critical applications?
A1: Required parameters include series, input voltage range, output voltage and current, power rating, isolation voltage, protection features, operating temperature, mounting type, package/case, dimensions, and compliance statuses.

Q2: Is VI-B6Z-CW-B1 mechanically compatible with designs utilizing VI-B6Z-CW?
A2: Both use full brick modules with identical length and width; the height of VI-B6Z-CW-B1 is increased (1.07" versus 0.50"). Mechanical fit must be evaluated based on available clearance in the target design.

Q3: Do both parts share the same electrical features and protection functions?
A3: Yes. The parts provide equivalent electrical performance including OCP, OTP, OVP, and SCP features.

Q4: Are there differences in environmental or compliance certifications between the two?
A4: Both are RoHS non-compliant and REACH unaffected, with no differences in ECCN or HTSUS classification.

Q5: What is the significance of product status when selecting substitutes?
A5: “Obsolete” status indicates supply limitations and end-of-life. Choosing an “Active” part ensures ongoing availability and support for new designs.
