Equivalent & Substitute Parts for Vicor VI-B4B-CW DC-DC Converter
Part Overview
The Vicor Corporation VI-B4B-CW is an isolated module DC-DC converter designed for ITE (Commercial) applications. The module delivers a single 95V output at up to 1.05A, with an input voltage range of 55V to 100V and a maximum power output of 100W. The product is part of the VI-200™ (100W) series, providing key protection features such as overcurrent, overtemperature, overvoltage, and short circuit protection. The VI-B4B-CW is now listed as obsolete, making it necessary to identify alternative models with matching electrical and mechanical specifications to support ongoing designs or maintenance.

Substitute Part Grouping Explanation
Substitute parts are grouped strictly by matching all key electrical and mechanical parameters for DC-DC converters. The parameters used for substitution are: input voltage range (55V to 100V), output voltage (95V), output current (1.05A), power rating (100W), voltage isolation (3kV), module type, number of outputs, protection features, efficiency, operating temperature, mounting type, package size, and compliance status. Only parts with all provided values identical to the main part are listed as substitutes.

Engineering Selection Recommendations
The VI-B4B-CW-B1 is an active product with technical parameters identical to the VI-B4B-CW in all key electrical, thermal, mechanical, and feature specifications, except for the height of the module. Both parts are RoHS non-compliant and share the same certifications and compliance status. Selection should be based on identical compliance requirements and compatibility with system certifications and assembly processes.
Frequently Asked Questions (FAQ)
Q: What are the main criteria for substituting the VI-B4B-CW DC-DC converter?
A: The main criteria are identical electrical parameters (input voltage range, output voltage, current, and power), mechanical form factor, protection features, operating temperature, mounting type, and compliance/certification status.
Q: Does the VI-B4B-CW-B1 fit as a direct mechanical replacement?
A: The VI-B4B-CW-B1 has an enlarged height dimension (1.07" vs. 0.50"). Mechanical compatibility must be verified for stack-up or enclosure constraints.
Q: Are there differences in electrical performance between the VI-B4B-CW and VI-B4B-CW-B1?
A: No. The input and output voltage ranges, current rating, efficiency, protection features, and all other specified electrical parameters are identical.
Q: Are both parts compliant with RoHS and REACH regulations?
A: Both the VI-B4B-CW and VI-B4B-CW-B1 are RoHS non-compliant and REACH unaffected.
Q: Can the same through-hole mounting process be used for both parts?
A: Yes. Both parts utilize the through-hole mounting type.
Q: What is the principal reason for requiring a substitute part?
A: The principal reason is the obsolete status of the VI-B4B-CW, necessitating a drop-in replacement with matching technical and compliance parameters.
Q: Is the active substitute part available with the same inventory level?
A: The available inventory is specific to each part and is not a selection criterion based on electrical or mechanical equivalence.
