VI-2WJ-EX Equivalent & Substitute Parts Reference
Part Overview
The Vicor Corporation VI-2WJ-EX is a DC DC Converter with an isolated module design, delivering 36V output at 2.08A from an 18V to 36V input voltage range. It supports 75 W power and features comprehensive protection (OCP, OTP, OVP, SCP), 3 kV isolation voltage, and mounts in a full brick through hole package. The device was designed for ITE (Commercial) applications. The product status is Obsolete, necessitating identification of direct alternative models for sustained system compatibility and procurement continuity.

Substitute Part Grouping Explanation
Substitute parts are identified strictly by matching the following parameters: manufacturer, series, product type, output configuration, input and output voltage ranges, current and power rating, isolation voltage, protection features, application suitability, efficiency, mounting type, package style, and size and compliance/certification parameters. Only alternatives with equivalent or identical performance in all these aspects are listed as substitutes.

Engineering Selection Recommendations
The VI-2WJ-EX is classified as Obsolete, and is RoHS non-compliant and REACH Unaffected. The substitute VI-2WJ-EX-B1 is Active, also RoHS non-compliant and REACH Unaffected. Only status differentiation exists, with electrical, mechanical, and compliance characteristics remaining consistent except for height dimension within the full brick package family.
Frequently Asked Questions (FAQ)
Q1: Which key parameters must match when selecting a substitute DC DC Converter for VI-2WJ-EX?
A1: Manufacturer, series, input voltage range, output voltage and current, power rating, isolation voltage, number of outputs, protection features, application category, mounting type, efficiency, package type, and compliance status.
Q2: Are there dimension differences between VI-2WJ-EX and its substitutes?
A2: The VI-2WJ-EX and VI-2WJ-EX-B1 both use a full brick package, but their heights differ, with VI-2WJ-EX at 0.50" (12.7mm) and VI-2WJ-EX-B1 at 1.07" (27.1mm).
Q3: Is RoHS compliance maintained in substitute parts?
A3: Both VI-2WJ-EX and VI-2WJ-EX-B1 are RoHS non-compliant.
Q4: Does the change in product status affect selection?
A4: The obsolete status of VI-2WJ-EX prompts the selection of the active VI-2WJ-EX-B1 for continued product availability.
Q5: Are application suitability and electrical protection features retained?
A5: All listed application categories and features (OCP, OTP, OVP, SCP) are identical across both parts.
