VI-B7Y-CW Equivalent & Substitute Parts Reference
Part Overview
The Vicor Corporation VI-B7Y-CW is an isolated module DC-DC converter in the VI-200™ (100W) series. It delivers a single output of 3.3V at up to 20A, accepting a wide input voltage range from 100V to 375V. Designed for ITE (Commercial) applications, it features overcurrent, overtemperature, overvoltage, and short circuit protection. With a power rating of 66W, 3kV isolation, 90% efficiency, and robust through-hole mounting in a full brick package, this device has served a variety of systems. The product is currently marked as obsolete, which necessitates selection of substitute models for continued production, maintenance, or design-in requirements.

Substitute Part Grouping Explanation
Substitution is determined strictly by matching key electrical, mechanical, and compliance parameters between the VI-B7Y-CW and available alternatives. The allowed criteria for substitution are:
- Manufacturer
- Product Series
- Electrical Ratings (Input Voltage Range, Output Voltage & Current, Power Rating)
- Isolation Voltage
- Features and Protections
- Mechanical Properties (Package, Mounting type, Size/Dimension)
- Environmental Ratings (Operating Temperature, Efficiency)
- Compliance (RoHS, REACH, Product Status)
Only parts matching these critical parameters are considered technically substitutable.

Engineering Selection Recommendations
The VI-B7Y-CW is classified as obsolete, while VI-B7Y-CW-B1 remains active and in production. Both models are RoHS non-compliant and REACH unaffected. Electrical performance, mechanical attributes, and compliance ratings are matched between the two. Selection of VI-B7Y-CW-B1 as a substitute maintains compatibility for applications requiring identical electrical, mechanical, and environmental characteristics, subject only to the height difference noted.
Frequently Asked Questions (FAQ)
Q1: What are the essential criteria for substituting VI-B7Y-CW with another part in this category?
A1: Substitution requires matching electrical ratings, mechanical form factor, features, isolation voltage, and compliance attributes exactly as specified.
Q2: Does the substitute model VI-B7Y-CW-B1 differ dimensionally from VI-B7Y-CW?
A2: Yes. Both are full brick packages with the same length and width. VI-B7Y-CW-B1 has a height of 1.07" compared to VI-B7Y-CW’s 0.50".
Q3: Are both VI-B7Y-CW and VI-B7Y-CW-B1 compliant with RoHS and REACH standards?
A3: Both parts are RoHS non-compliant and REACH unaffected.
Q4: Do the substitute and main part offer the same protection and features?
A4: Yes. Both provide OCP (Overcurrent Protection), OTP (Overtemperature Protection), OVP (Overvoltage Protection), and SCP (Short Circuit Protection).
Q5: Is there any difference in input or output voltage, current, or power ratings between these parts?
A5: No. Both deliver 3.3V output at up to 20A, support 100V-375V input, and are rated at 66W maximum power.
Q6: What mounting type and package do these converters utilize?
A6: Both are through hole mounted in full brick cases.
Q7: What is the rationale for substituting VI-B7Y-CW with VI-B7Y-CW-B1?
A7: The main part is obsolete, and the substitute part matches all key parameters while remaining active in production.
