VI-2WW-MW Equivalent & Substitute Parts Reference

Part Overview

The Vicor Corporation VI-2WW-MW is a DC DC converter within the VI-200™ (100W) series. It is an isolated module providing a single 5.5V output at up to 18.18A, operating from an 18V to 36V input range, and delivering up to 100W of output power. This model is designed for ITE (Commercial) applications, features through-hole mounting, and includes advanced protections such as OCP, OTP, OVP, and SCP. The VI-2WW-MW is classified as obsolete, necessitating the identification of alternative models with equivalent parameters to ensure ongoing design continuity and support for existing assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified strictly according to the following parameters: input voltage range, output voltage, output current, output power, voltage isolation rating, function (isolated module), protections/features present, mounting style, package/case type and size, efficiency, application category, and environmental ratings. The substitute part VI-2WW-MW-B1 matches all critical parameters required for functional and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Product status is a primary factor in substitution. The main part, VI-2WW-MW, is classified as obsolete, while VI-2WW-MW-B1 is active. Both models share identical compliance status (RoHS non-compliant, REACH unaffected) and hold the same environmental and application ratings, ensuring alignment in regulatory and usage contexts. Select VI-2WW-MW-B1 for direct substitution where product status or lifecycle is critical.

Frequently Asked Questions (FAQ)

Q1: What parameters determine if VI-2WW-MW-B1 can substitute VI-2WW-MW?
A1: Key parameters include input voltage range, output voltage, output current, power rating, voltage isolation, protections/features, mounting type, package/case, efficiency, operating temperature, and compliance status.

Q2: Is there any mechanical difference between VI-2WW-MW and VI-2WW-MW-B1?
A2: The base footprint (length and width) is identical; the height differs, with VI-2WW-MW-B1 at 1.07" and VI-2WW-MW at 0.50".

Q3: Are there compliance differences between the parts?
A3: Both VI-2WW-MW and VI-2WW-MW-B1 are RoHS non-compliant and REACH unaffected.

Q4: Can VI-2WW-MW-B1 be used in the same applications as VI-2WW-MW?
A4: Both parts are rated for ITE (Commercial) applications and have matching electrical and mechanical parameters except for height.

Q5: What package or mounting considerations apply for substitution?
A5: Both parts use a full brick, through-hole package; only the overall height differs.

Q6: Does the operating temperature differ?
A6: Both parts have the same operating temperature range: -55°C to 85°C.

Q7: Does the substitution require any changes in approvals or certifications?
A7: Both parts are ECCN EAR99 and share the same HTSUS code; no differences in provided regulatory status.
