Vicor VI-B3Y-EW Equivalent & Substitute Parts Reference

Part Overview

The Vicor VI-B3Y-EW is an isolated module DC DC converter designed for ITE (commercial) applications, offering a single 3.3V output at up to 20A from a 42V – 60V input range. This 66W power converter is configured in a full brick through-hole package and features protections such as OCP, OTP, OVP, and SCP. The VI-B3Y-EW is currently obsolete. As this part is no longer in production, finding equivalent substitute parts with matching electrical and mechanical parameters is necessary for ongoing design and maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution in the DC DC converter isolated module category is determined by matching critical electrical and mechanical parameters to ensure compatibility. The substitute part listed meets the following matching key parameters: manufacturer, series, type, input voltage range, output voltage, output current, power rating, isolation voltage, functional protections, applications, operating temperature, efficiency, mounting type, package size, compliance status, and certifications. This ensures direct interchangeability without deviation from provided specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary selection should be based on product status and compliance with RoHS and REACH requirements. The VI-B3Y-EW is obsolete; the VI-B3Y-EW-B1 is listed as active. Both parts are not RoHS compliant but have unaffected REACH status and identical ECCN codes. Certifications and compliance statuses are equivalent between main and substitute parts under the provided parameters.

Frequently Asked Questions (FAQ)

Q1: What electrical parameters dictate direct substitution for DC DC converter isolated modules?
A1: Input voltage range, output voltage, output current, power rating, isolation voltage, protections, efficiency, and operating temperature must match exactly.

Q2: Are mounting type and package dimensions relevant for substitution?
A2: Yes. Both VI-B3Y-EW and its substitute VI-B3Y-EW-B1 use through-hole mounting in a full brick case, with only height differing. All other dimensions are identical.

Q3: Is regulatory compliance the same for both models?
A3: Both parts are RoHS non-compliant and REACH unaffected. ECCN code EAR99 applies to both.

Q4: Is the substitute part active and available?
A4: The VI-B3Y-EW-B1 is active and in inventory per provided data.

Q5: Can this substitution be made without changing existing system electrical or mechanical designs?
A5: Electrical substitution is valid; mechanical fit must confirm with the height difference specified (0.50" vs 1.07"). All other key parameters are matched.
