Vicor VI-B5R-EV Equivalent & Substitute Parts Reference

Part Overview

The Vicor VI-B5R-EV is an isolated module DC-DC converter that provides a single 7.5V output at a maximum current of 20A, supporting input voltages from 100V to 200V. It is designed for ITE (Commercial) applications and features integrated protections including OCP, OTP, OVP, and SCP. The VI-B5R-EV has been classified as obsolete, making it necessary to identify alternative models for designs requiring continued manufacturing support or repair. Appropriate substitute selection is critical to maintain system performance and reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are strictly grouped based on electrical and mechanical parameters that are critical for DC-DC converter interchangeability. These key parameters include manufacturer and series, input voltage range, output voltage and current, power rating, isolation voltage, application, protection features, efficiency, mounting type, package/case, and size/dimensions. Only parts with matching values in these criteria are considered suitable substitutes.

Parameter Comparison

Engineering Selection Recommendations

The main part VI-B5R-EV is obsolete and RoHS non-compliant. The substitute VI-B5R-EV-B1 is active and also RoHS non-compliant. Both units share identical electrical and mechanical specifications, including input range, output characteristics, protection features, operating temperature, mounting type, and application compatibility. The only dimensional difference is the height, which should be verified against design enclosure constraints. Compliance status for MSL and REACH remains unchanged.

Frequently Asked Questions (FAQ)

Q1: Which parameters are mandatory for substitution compatibility?
Electrical compatibility (input voltage range, output voltage and current, power rating, isolation voltage), mechanical form factor (package/case type, mounting), and protection features are mandatory for substitution.

Q2: Is the VI-B5R-EV-B1 footprint compatible with the VI-B5R-EV?
Both models utilize the Full Brick package and through hole mounting. The substitute (VI-B5R-EV-B1) has a greater height (1.07" vs 0.50"), which must be accommodated in mechanical design.

Q3: Are there differences in compliance or safety approvals?
Both parts are RoHS non-compliant and REACH unaffected. ECCN and HTSUS codes are identical.

Q4: Does the change in product status affect supply strategy?
The substitute VI-B5R-EV-B1 is active, supporting ongoing procurement and long-term maintenance requirements, whereas VI-B5R-EV is obsolete.

Q5: Are there any differences in environmental tolerances?
The substitute part matches the operating temperature range and protection features of the main part.

Q6: What application environments are supported?
Both parts are designed for ITE (Commercial) environments.
