VI-B70-EX-B1 Equivalent & Substitute Parts Reference
Part Overview
The Vicor Corporation VI-B70-EX-B1 is an isolated DC-DC converter module delivering a single 5V output at 15A, with a wide input voltage range from 100V to 375V. Part of the VI-200™ (75W) series, it is no longer in production and is classified as obsolete. Finding substitute models is necessary for continued system maintenance or new designs requiring similar electrical and mechanical characteristics due to product discontinuation.

Engineering Selection Recommendations
The VI-B70-EX-B1 is obsolete and no longer available from the manufacturer, while the VE-B60-EX-B1 is currently active. Both parts are ROHS3 Compliant, with unaffected REACH status, and certified for CE, cURus, and cTUVus standards. Selection between these two should be based on availability and compliance status. All specified certifications and environmental compliance parameters must be matched as listed.
Frequently Asked Questions (FAQ)
Q1: What are the substitution criteria for VI-B70-EX-B1?
Substitution is determined by matching output voltage, output current, isolation voltage, application type, operating temperature, efficiency, and compliance with RoHS and REACH statuses.
Q2: How does the input voltage range affect compatibility?
Only parts with input voltage ranges within the original specifications are interchangeable. VE-B60-EX-B1 has a minimum input voltage of 200V and a maximum of 400V, differing from the VI-B70-EX-B1.
Q3: Are the mechanical dimensions and mounting types critical for substitution?
Physical footprint and mounting type (Chassis Mount vs. Through Hole) should match system requirements exactly. Size and mounting must be considered to maintain system integrity.
Q4: Are certifications and compliance status matched in substitutes?
Both parts are ROHS3 Compliant and REACH Unaffected, with identical certifications and regulatory classifications.
Q5: Does the substitute support the same operating temperature and efficiency?
Operating temperature and efficiency (88%) are matched between VI-B70-EX-B1 and VE-B60-EX-B1.
