Equivalent & Substitute Parts Reference for VI-BT4-EW-F1

Part Overview

The Vicor Corporation VI-BT4-EW-F1 is an isolated DC-DC converter module within the VI-200™ (100W) Series. It is designed for ITE (Commercial) applications, providing a single 48V output at 1.04A from a 66V to 160V DC input, delivering up to 100W output power. With 3 kV isolation, multiple protection features, and through-hole mounting in a full brick package, this module has historically served critical roles in power conversion designs. As the VI-BT4-EW-F1 is now obsolete, it is necessary to identify alternative models with matching electrical, mechanical, and compliance parameters to ensure continuity in affected designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute part selection for isolated DC-DC converter modules requires strict adherence to key parameters including input voltage range, output voltage, output current, power rating, isolation voltage, operational features, efficiency, application category, temperature rating, mounting type, package size, and compliance status (RoHS, REACH, MSL, ECCN). Only modules matching these specified criteria qualify as legitimate functional substitutes.

Parameter Comparison

Engineering Selection Recommendations

The main part, VI-BT4-EW-F1, is classified as obsolete. The VI-BT4-EW-F2 is active, and all provided compliance markings (RoHS non-compliance, REACH unaffected, MSL, ECCN, HTSUS) are consistent between both parts. Both units share identical electrical, mechanical, and application specifications, with the exception of module height. Selection based on regulatory, certification, and inventory status should favor the active part VI-BT4-EW-F2 when the package height is compatible with system constraints.

Frequently Asked Questions (FAQ)

Q1: What are the required criteria for selecting a substitute for VI-BT4-EW-F1?
A1: Required criteria include matching input voltage range, output voltage, output current, output power, isolation voltage, features, operating temperature, efficiency, mounting type, form factor, and compliance marks.

Q2: Are there any physical differences between VI-BT4-EW-F1 and VI-BT4-EW-F2 impacting direct replacement?
A2: The primary physical difference is height; VI-BT4-EW-F1 is 0.79" high, while VI-BT4-EW-F2 is 1.05". Width and length are identical.

Q3: Is there any difference in regulatory compliance between these parts?
A3: Both parts are RoHS non-compliant, REACH unaffected, and share the same ECCN and HTSUS codes.

Q4: Does the difference in product status affect qualification for listed applications?
A4: Product status only affects long-term supply; operational and compliance qualifications remain unchanged between the active and obsolete versions.

Q5: Should application designers be concerned about other performance differences?
A5: According to the provided parameters, electrical, mechanical (except height), and compliance specifications are identical. No distinction in performance exists outside those parameters.
