Vicor VI-B7Y-EW Equivalent & Substitute Parts Reference

Part Overview

The Vicor VI-B7Y-EW is categorized as an isolated DC-DC converter module featuring one output of 3.3V at up to 20A, suitable for ITE (commercial) applications. The module operates over a wide input voltage range from 100V to 375V, with 3kV isolation and support for protection features such as OCP, OTP, OVP, and SCP. The product has an efficiency of 88%, mounts via through-hole in a full brick package, and dimensions of 4.60" x 2.40" x 0.50". Its series is VI-200™ (100W), and it is currently listed as obsolete. When a product reaches obsolete status, it is necessary to identify alternative models to ensure continuity of supply and maintain design compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Vicor VI-B7Y-EW are identified by matching the following key parameters: manufacturer, series, type, input voltage range, output specifications, isolation voltage, feature set, applications, mounting type, package size, and compliance status. All parameters must align exactly to ensure the substitute provides equivalent electrical and mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The main part VI-B7Y-EW is obsolete, while the substitute VI-B7Y-EW-B1 is active. Both parts are RoHS non-compliant, REACH unaffected, and classified under ECCN EAR99. For applications requiring continued product availability, the selection should be based on maintaining identical electrical, mechanical, and compliance characteristics. The substitute VI-B7Y-EW-B1 complies with all matched criteria except for a different height (1.07" vs. 0.50" for the main part). This dimensional variation should be considered in mechanical integration.

Frequently Asked Questions (FAQ)

Q1: What electrical specifications must match when selecting a substitute for the Vicor VI-B7Y-EW?
A1: Substitute selection requires identical input voltage range, output voltage and current, power rating, isolation voltage, and feature set.

Q2: Can VI-B7Y-EW-B1 be used directly as a replacement for VI-B7Y-EW?
A2: VI-B7Y-EW-B1 shares all electrical parameters and features, with only a difference in physical height.

Q3: How does the package difference affect the selection?
A3: Both parts use the full brick package but differ in height (0.50" vs. 1.07"). Application-specific clearance should be verified.

Q4: Are there any differences in compliance or certifications?
A4: Both parts are RoHS non-compliant, REACH unaffected, and have identical ECCN and HTSUS codes.

Q5: Does product status matter in substitute selection?
A5: Yes. The VI-B7Y-EW is obsolete, and the VI-B7Y-EW-B1 is active, making the latter suitable for ongoing designs.

Q6: Is it necessary to match the exact manufacturer and series for DC-DC converter substitutions?
A6: Matching manufacturer and series ensures compatibility regarding electrical, mechanical, and feature specifications within the same product line.
