Equivalent & Substitute Parts for Vicor VI-B50-EX-F2

Part Overview

The Vicor Corporation VI-B50-EX-F2 is an isolated DC-DC converter module providing a single 5V output at up to 15A with 75W of rated power. It is classified under the VI-200™ (75W) series and designed for ITE (Commercial) applications. Key features include overcurrent, overtemperature, overvoltage, and short circuit protection. The VI-B50-EX-F2 is obsolete, making it necessary to identify compatible substitute models that strictly satisfy replacement criteria within its product category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected by matching the following explicit parameters: input voltage range (100V–200V), output voltage (5V), output current (15A), power rating (75W), isolation voltage (3kV), number of outputs (1), environmental features (OCP, OTP, OVP, SCP), mounting type (Through Hole), package (Full Brick), and dimensions. Only series, regulatory, and application-specific parameters are used. Substitution is made when all these fields are strictly identical or compatible as per provided data. Obsolescence of the original part is the substitution driver.

Parameter Comparison

Engineering Selection Recommendations

The VI-B50-EX-F2 part is obsolete. The VI-B50-EX-F3 is active and matches all primary electrical and mechanical parameters. Both models are RoHS non-compliant and REACH unaffected, with equivalent regulatory status and classification (ECCN, HTSUS). The only dimensional difference is height (1.05" vs 0.79"). Selection should be limited to parts with matching compliance profiles and physical dimensions as per application requirements.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for substituting VI-B50-EX-F2 with VI-B50-EX-F3?
A1: The primary criteria are identical electrical ratings (input voltage, output voltage, output current, power, isolation), package type, mounting style, and environmental ratings, as shown in the parameter comparison.

Q2: Is the substitution compatible with the same mounting and enclosure?
A2: Both parts use the Full Brick format and Through Hole mounting. The height differs (1.05" for VI-B50-EX-F2, 0.79" for VI-B50-EX-F3), which may affect vertical clearance in some designs.

Q3: Are there certification or regulatory differences that would prevent substitution?
A3: Both parts are RoHS non-compliant and REACH unaffected. There are no differences in regulatory codes (ECCN: EAR99; HTSUS: 8504.40.9580).

Q4: Is feature compatibility maintained between the original and substitute?
A4: Both feature OCP, OTP, OVP, SCP protections. Operating temperature range and efficiency are identical.

Q5: How critical is the height difference for system integration?
A5: The only dimensional variance is the module height. System fit must be verified against enclosure and stack-up constraints based strictly on this provided measurement.
