Vicor VI-2WW-IW Equivalent & Substitute Parts Reference

Part Overview

The Vicor VI-2WW-IW is an isolated DC-DC converter module, providing a single 5.5V output at up to 18.18A from a 18V to 36V input, with a maximum power rating of 100 W. The module is designed for ITE (Commercial) applications, with built-in OCP, OTP, OVP, and SCP protection features. The product is currently obsolete. For applications requiring continued supply or on-going support, it is necessary to identify suitable alternative or substitute modules with matching key electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

The substitute part, Vicor VI-2WW-IW-B1, is identified strictly based on the following electrical and mechanical parameters, which are critical in DC-DC converter module selection:

• Input voltage range (18V to 36V)
• Output voltage (5.5V)
• Maximum output current (18.18A)
• Maximum power output (100 W)
• Voltage isolation (3 kV)
• Protection features (OCP, OTP, OVP, SCP)
• Mounting type (Through Hole)
• Package / case (Full Brick)
• Series affiliation (VI-200™ (100W))
• Operating temperature range (-40°C ~ 85°C)
• Efficiency (90%)
• RoHS and REACH compliance status

Only parts strictly matching these parameters and sharing mechanical compatibility are considered as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The main part number Vicor VI-2WW-IW is obsolete, while the substitute part Vicor VI-2WW-IW-B1 is active and available in inventory. Both parts are RoHS non-compliant and have REACH unaffected status. No change in product certifications or compliance is present between the two listed modules.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to determine if Vicor VI-2WW-IW-B1 is a substitute for Vicor VI-2WW-IW?
A1: Substitution is based strictly on matching electrical parameters (input voltage range, output voltage, output current, power, isolation voltage), protection features, mounting type, package size (full brick), and series. Compliance status and mechanical dimensions must also be considered.

Q2: Are there differences in form factor or footprint between VI-2WW-IW and VI-2WW-IW-B1?
A2: Both are Full Brick modules with identical length and width. The height differs, with VI-2WW-IW at 0.50" (12.7mm) and VI-2WW-IW-B1 at 1.07" (27.1mm). Footprint compatibility should be reviewed against mechanical height constraints.

Q3: Are compliance certifications affected when substituting with VI-2WW-IW-B1?
A3: Both the original and substitute part are RoHS non-compliant and REACH unaffected, with matching ECCN and HTSUS codes. There is no change in compliance certifications.

Q4: Does the active status of VI-2WW-IW-B1 influence selection?
A4: Yes, as VI-2WW-IW is obsolete and VI-2WW-IW-B1 is active, selecting the active part ensures ongoing availability.

Q5: Are there any features that differ in functionality between the two modules?
A5: Both modules provide OCP, OTP, OVP, and SCP protections. There are no differences in protection feature sets based on provided parameters.
