Equivalent & Substitute Parts for Vicor Corporation VI-2NT-CW

Part Overview

The Vicor Corporation VI-2NT-CW is an isolated DC-DC converter module with a single 6.5V output at up to 15.38A (100W) and a wide input range of 36V to 76V. It features a full brick through-hole package and offers various protections such as OCP, OTP, OVP, and SCP. This model is classified as obsolete. When a DC-DC converter reaches obsolete status, finding alternative models with strict compliance to electrical, mechanical, and regulatory specifications is necessary to ensure long-term product maintenance and compatibility in electronic systems.

Engineering Selection Recommendations

Selection between VI-2NT-CW and VI-2NT-CW-B1 can be based on product status and compliance factors. VI-2NT-CW is classified as obsolete, while VI-2NT-CW-B1 is active. Both models are RoHS non-compliant and unaffected by REACH regulations. The package height differs; mechanical fit should be verified according to system requirements.

Frequently Asked Questions (FAQ)

Q1: What are the primary criteria for selecting a substitute for VI-2NT-CW?
A1: The substitute must have matching input voltage range, output voltage, output current, output power, isolation voltage, efficiency, operating temperature, mounting type, package, and feature set.

Q2: Are there package differences between VI-2NT-CW and VI-2NT-CW-B1?
A2: Both are full brick through-hole modules, but the VI-2NT-CW-B1 has a greater height at 1.07" compared to 0.50" for the VI-2NT-CW.

Q3: Is there any difference in electrical performance between the two models?
A3: All listed electrical parameters are identical between the two models.

Q4: How do RoHS and REACH status affect selection?
A4: Both models have identical compliance status: RoHS non-compliant and REACH unaffected. This must align with application regulatory requirements.

Q5: Why is substitution necessary for VI-2NT-CW?
A5: The VI-2NT-CW is obsolete; selecting an equivalent active model is necessary to ensure continued availability and support.
