Vicor VI-B2P-EW Equivalent & Substitute Parts Reference

Part Overview

The Vicor VI-B2P-EW is a DC-DC isolated module in the VI-200™ (100W) product series. It provides a single 13.8V output at up to 7.25A from a 21V–56V input. The module supports features such as over-current, over-temperature, and over-voltage protection. The device utilizes a full brick through-hole package and is designed for ITE (Commercial) applications requiring high isolation voltage (3kV). The VI-B2P-EW is currently obsolete, making it necessary to identify equivalent or substitute parts to ensure ongoing support for maintenance, production, or system design continuity.

Substitute Part Grouping Explanation

Substitute DC-DC isolated modules must match the main device's electrical and mechanical parameters. Allowed substitutions require identical or compatible values for input voltage range (21V–56V), output voltage (13.8V), output current (7.25A), power rating (100W), isolation voltage (3kV), protection features (OCP, OTP, OVP, SCP), efficiency (88%), and mounting/package dimensions. In this device category, only modules matching these criteria and compliance parameters are listed as functional equivalents.

Key substitution parameters:

Manufacturer and series
Input voltage range
Output voltage and output current
Power rating
Isolation voltage
Protection features
Efficiency
Mounting, package, and physical dimensions
Compliance and environmental status

Engineering Selection Recommendations

The Vicor VI-B2P-EW-B1 offers identical electrical and environmental characteristics as the obsolete VI-B2P-EW, with only a difference in module height (1.07" vs. 0.50"). Both parts are RoHS non-compliant and are unaffected by REACH status. Both are classified under ECCN EAR99 and HTSUS 8504.40.9580. Selection must be based on the product status (active or obsolete) and compliance requirements. For applications requiring an active status module, the VI-B2P-EW-B1 is suitable if the height increase does not affect system integration.

Frequently Asked Questions (FAQ)

Q1: What are the main compatibility requirements when substituting Vicor VI-B2P-EW?
A1: Compatibility is determined by matching input voltage range, output voltage and current, power capacity, isolation voltage, mounting type, protection features, efficiency, and package size.

Q2: Does the substitute part VI-B2P-EW-B1 require modifications to the PCB footprint?
A2: Both parts use the full brick package and through-hole mounting; only the height dimension is increased (1.07" vs. 0.50").

Q3: Are both parts RoHS and REACH compliant?
A3: Both are RoHS non-compliant and REACH unaffected.

Q4: Is there any difference in electrical performance between VI-B2P-EW and VI-B2P-EW-B1?
A4: The electrical parameters, features, and environmental ratings are identical for both parts.

Q5: Can the part be used in applications requiring ECCN EAR99 and HTSUS 8504.40.9580 classification?
A5: Both VI-B2P-EW and VI-B2P-EW-B1 meet ECCN EAR99 and HTSUS 8504.40.9580 classifications.

Q6: What is the significance of the product status for selection?
A6: The main part VI-B2P-EW is obsolete; the substitute VI-B2P-EW-B1 is active, enabling ongoing sourcing and support.
