Equivalent & Substitute Parts for Vicor VI-B5B-EV DC-DC Converter

Part Overview

The Vicor Corporation VI-B5B-EV is a DC-DC converter isolated module in the VI-200™ (150W) series. It provides a single 95V output at up to 1.58A from a 100V – 200V DC input. The module features isolation of 3 kV, includes OCP, OTP, OVP, and SCP protection, and is designed for ITE (Commercial) applications. It is mounted via through-hole in a Full Brick case. The product status is Obsolete, making it necessary to identify alternative models for system designs requiring continued availability or direct replacement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Vicor VI-B5B-EV are grouped based strictly on matching key electrical and mechanical parameters, including: input voltage range (100V–200V), output voltage (95V), maximum output current (1.58A), power rating (150W), isolation voltage (3 kV), features (OCP, OTP, OVP, SCP), operating temperature (-10°C ~ 85°C), efficiency (88%), mounting type (Through Hole), and package/case type (Full Brick). Only parts having identical or equivalent values for these parameters are considered valid substitutes.

Parameter Comparison

Engineering Selection Recommendations

Substitution is determined by the matching of all electrical and mechanical parameters, product status, and compliance information. VI-B5B-EV-B1 is an appropriate substitute for VI-B5B-EV, matching all key parameters and featuring an Active status. Both parts are RoHS non-compliant and REACH unaffected. Users must ensure physical compatibility, specifically the height dimension, as that is the only differentiator among the shared parameters provided.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for substituting the Vicor VI-B5B-EV DC-DC converter?
A1: Substitution is based on identical input and output voltage ranges, output current, power rating, isolation voltage, protection features, efficiency, operating temperature, mounting type, package/case, and compliance status.

Q2: Is the VI-B5B-EV-B1 a direct electrical substitute for the VI-B5B-EV?
A2: Yes; the VI-B5B-EV-B1 matches all critical electrical specifications, including input range, output voltage, output current, power, isolation, and features.

Q3: Are there package differences between VI-B5B-EV and VI-B5B-EV-B1?
A3: Yes; both use a Full Brick package, but the height differs: VI-B5B-EV is 0.50" high, while VI-B5B-EV-B1 is 1.07" high.

Q4: Do both models have the same compliance status?
A4: Yes; both are RoHS non-compliant and REACH unaffected.

Q5: What should be considered for mechanical compatibility?
A5: When substituting, the primary consideration is the height dimension if space constraints are present. Both models utilize a Full Brick footprint.
