Equivalent & Substitute Parts Reference for Vicor VI-B5T-CX-F3

Part Overview

The Vicor VI-B5T-CX-F3 is a DC-DC converter module rated for isolated operation with a single 6.5V output at up to 11.54A, accepting input voltages from 100V to 200V. This full brick module, classified under the VI-200™ (75W) series, delivers 75W maximum output with 3 kV isolation and integrated features including overcurrent, overtemperature, overvoltage and short circuit protection. The product is listed as obsolete, making it necessary to identify strictly compatible substitute parts for applications requiring continued availability, identical specifications, and compliance alignment.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for DC-DC converter modules is determined strictly by the following key parameters: input voltage range, output voltage, maximum output current, power rating, isolation voltage, type, number of outputs, mounting and package specifications, operating temperature range, efficiency, electrical protection features, and compliance status. Substitute parts must match these criteria precisely to ensure functional and form-fit compatibility, with the exception of product status, which may differ if availability or lifecycle requires.

Parameter Comparison

Engineering Selection Recommendations

Both Vicor VI-B5T-CX-F3 and Vicor VI-B5T-CX-F2 share identical electrical and mechanical parameters as provided, with the exception of product status and height dimension within the full brick format. Both models are RoHS non-compliant and REACH unaffected, listed under ECCN: EAR99 and HTSUS: 8504.40.9580, with moisture sensitivity not applicable. VI-B5T-CX-F2 is currently active, making it suitable for designs where continued lifecycle and availability are specified as requirements.

Frequently Asked Questions (FAQ)

Q1: Which parameters are critical for substituting DC-DC converters within this series?
A1: Substitution is determined strictly by input voltage range, output voltage, output current, power rating, isolation voltage, module type, number of outputs, mounting type, package/case format, operating temperature range, efficiency, features, and compliance status.

Q2: Are there mechanical differences between VI-B5T-CX-F3 and VI-B5T-CX-F2 that affect mounting?
A2: Both models use the full brick format with the same length and width. The module height for VI-B5T-CX-F3 is 0.79", while VI-B5T-CX-F2 is 1.05". Mounting compatibility should be verified relative to the vertical clearance in the application.

Q3: Do compliance and certifications affect substitution?
A3: Both VI-B5T-CX-F3 and VI-B5T-CX-F2 are RoHS non-compliant, REACH unaffected, and rated ECCN: EAR99. These compliance statuses must be considered for regulated environments but do not restrict direct substitution where identical certifications are specified.

Q4: Is electrical performance identical between the substitute and main part as provided?
A4: VI-B5T-CX-F2 matches VI-B5T-CX-F3 in input voltage, output voltage, maximum output current, power rating, isolation, efficiency, operating temperature, and integrated features.
