VI-J3B-CW Equivalent & Substitute Parts Reference

Part Overview

The Vicor Corporation VI-J3B-CW is an isolated DC-DC converter module from the VI-J00™ (100W) Series. It provides one regulated 95V output at up to 1.05A from a 42V to 60V input and is rated for 100W output power. This module is obsolete, which necessitates the selection of alternative models to ensure ongoing design support and availability for maintenance, repair, or new production. The evaluation of equivalent or substitute parts is focused on exact matches for electrical performance, mechanical dimensions, and compliance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VI-J3B-CW are determined by matching all relevant electrical, thermal, and mechanical parameters, including input and output voltage, output current, power, features (such as OCP and SCP), isolation voltage, operating temperature, form factor, and compliance information. Only parts with compatible specifications in these fields are included as substitutes.

Key allowed parameters for substitution:

• Series
• Type
• Number of Outputs
• Voltage - Input (Min/Max)
• Voltage - Output 1
• Current - Output (Max)
• Power (Watts)
• Voltage - Isolation
• Features
• Operating Temperature
• Efficiency
• Mounting Type
• Package / Case
• Size / Dimension
• RoHS/Compliance Status
• REACH Status
• Base Product Number

Engineering Selection Recommendations

The VI-J3B-CW is designated as obsolete, while the VI-J3B-CW-F1 is active. Both modules are not RoHS compliant and share REACH unaffected status. Only parts sharing the same compliance and certification fields are suitable for direct replacement in designs that must maintain consistent environmental and regulatory conditions.

Frequently Asked Questions (FAQ)

Q1: Which parameters must match for direct substitution of the VI-J3B-CW?
A1: Direct substitution requires identical series, input and output voltage ranges, output current, power rating, isolation voltage, protection features, operating temperature, efficiency, mounting style, package/case type, compliance status, and base product number.

Q2: Can the VI-J3B-CW-F1 be used as a substitute for the VI-J3B-CW?
A2: The VI-J3B-CW-F1 matches the key electrical and mechanical parameters and compliance criteria required for substitution.

Q3: Are there mechanical differences that affect interchangeability?
A3: Both models use the Half Brick package and Through Hole mounting, but the width and height dimensions vary slightly. Dimensional compatibility should be verified against the specific end-application's mechanical constraints.

Q4: Do RoHS and REACH statuses impact substitution?
A4: Both parts are RoHS non-compliant and REACH unaffected. Substitution is suitable only for applications that do not require RoHS compliance.

Q5: Is the VI-J3B-CW-F1 available for ongoing production?
A5: VI-J3B-CW-F1 status is active, supporting current and future production, while VI-J3B-CW is obsolete.
