Vicor VI-BT3-EX Equivalent & Substitute Parts Reference
Part Overview
The Vicor VI-BT3-EX is an isolated DC DC converter module featuring a single 24V output at 2.08A with a 66V to 160V input range, rated for 75W power and designed for ITE (Commercial) applications. Its features include overcurrent protection (OCP), overtemperature protection (OTP), overvoltage protection (OVP), and short circuit protection (SCP). The VI-BT3-EX is now classified as Obsolete, making it necessary to identify substitute models with identical or matching parameters for continuity in engineering designs and maintenance.

Substitute Part Grouping Explanation
Substitution is determined strictly by the following key parameters: module type, number of outputs, input voltage range, output voltage and current, power rating, isolation voltage, application, feature set, operating temperature, efficiency, mounting type, package/case, physical dimensions, and regulatory compliance. Only parts matching all these parameters are classified as substitutes.

Engineering Selection Recommendations
Selection is based on product status and regulatory compliance fields provided. The VI-BT3-EX is Obsolete, while the VI-BT3-EX-B1 is Active. Both are RoHS non-compliant and REACH Unaffected, with Not Applicable Moisture Sensitivity Level. These compliance and status parameters are to be considered when selecting a substitute within the same application requirements.
Frequently Asked Questions (FAQ)
Q1: What criteria determine whether a substitute DC DC converter module is compatible with the VI-BT3-EX?
A1: Substitution is determined strictly by matching electrical parameters (input voltage range, output voltage, output current, power rating, isolation voltage), module type, features, application, package, mounting type, physical dimensions, operating temperature, efficiency, and regulatory compliance as provided.
Q2: Are the package or physical dimensions of the substitute part identical to the VI-BT3-EX?
A2: VI-BT3-EX-B1 has identical length and width but a different height (1.07" vs 0.50"), both in a full brick package.
Q3: Does using VI-BT3-EX-B1 require changes in regulatory or compliance documentation?
A3: Both modules are RoHS non-compliant and REACH Unaffected. Moisture Sensitivity Level is Not Applicable for both.
Q4: Can the substitute part be used in the same types of ITE (Commercial) applications?
A4: Application classification is identical for both modules.
Q5: Are there differences in electrical performance or protection features?
A5: There are no differences in input range, output voltage/current, power, efficiency, or features between VI-BT3-EX and VI-BT3-EX-B1 as per the provided data.
Q6: How does the product status affect substitution?
A6: VI-BT3-EX is Obsolete; VI-BT3-EX-B1 is Active. Current applications requiring an Active status should use VI-BT3-EX-B1.
