Vicor VI-2TH-CV Equivalent & Substitute Parts Reference

Part Overview

The Vicor VI-2TH-CV is an obsolete isolated module DC-DC converter delivering a single 52V output at 2.88A, within a 66V to 160V input range, rated at 150W output power. It features 3kV isolation, OCP, OTP, OVP, SCP protections, and through-hole, full-brick mounting format. The product status is obsolete, creating a requirement to find a functionally equivalent substitute for continued system maintenance, repair, or production.

Parameter Comparison

Engineering Selection Recommendations

The recommended substitute for the obsolete Vicor VI-2TH-CV is the Vicor VI-2TH-CV-B1. The substitute part matches all key electrical characteristics, protections, and mounting type. Both parts are RoHS non-compliant and are designed for ITE (Commercial) applications. The substitute part is currently active, ensuring continued availability. Attention should be given to the mechanical size/dimension change, specifically the height.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for determining a substitute for the Vicor VI-2TH-CV?
A1: The main criteria are number of outputs, input voltage range, output voltage and current, power, isolation voltage, mounting style, package type, efficiency, protection features, temperature range, and compliance status.

Q2: Is the Vicor VI-2TH-CV-B1 package compatible with the original VI-2TH-CV?
A2: Both parts use the full brick package format and through-hole mounting. The primary dimensional difference is the height: VI-2TH-CV-B1 is 1.07" (27.1mm) versus 0.50" (12.7mm) for the VI-2TH-CV.

Q3: Are there differences in electrical performance between VI-2TH-CV and VI-2TH-CV-B1?
A3: Based on the provided parameters, all specified electrical performance attributes are identical.

Q4: What compliance considerations apply when substituting these parts?
A4: Both the original and substitute parts are RoHS non-compliant and REACH unaffected. No changes in compliance status should be expected.

Q5: Can the substitute part be directly installed in the same PCB footprint?
A5: The full brick format and through-hole mounting are compatible; only the increased height of the VI-2TH-CV-B1 should be verified against mechanical enclosure or stacking constraints.

Q6: Do the thermal or environmental ratings differ?
A6: Both parts specify an identical operating temperature range of -25°C to 85°C.
