VI-2NJ-EX Equivalent & Substitute Parts Reference

Part Overview

The Vicor Corporation VI-2NJ-EX is a DC DC converter module categorized as an Isolated Module. It operates with a single output of 36V at a maximum current of 2.08A, accepting a wide input voltage range from 36V to 76V. It delivers up to 75 W power and features a 3 kV isolation voltage with integrated protection functions (OCP, OTP, OVP, SCP). The product is obsolete, which necessitates identification of alternative models for ongoing repair, replacement, or design-in to maintain equipment compatibility and supply continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute grouping is based exclusively on exact matching of electrical characteristics, mechanical compatibility, and compliance status. The allowed parameters for substitution in this product category include: manufacturer, series, electrical ratings (input/output voltage, current, power, isolation voltage), output configuration, protection features, efficiency, operating temperature range, mounting type, package, size/dimension, and regulatory status (RoHS, REACH, ECCN, HTSUS).

Parameter Comparison

Engineering Selection Recommendations

Selection between VI-2NJ-EX and VI-2NJ-EX-B1 can be based on product status and compliance information. VI-2NJ-EX is obsolete, while VI-2NJ-EX-B1 is active. Both parts are RoHS non-compliant and REACH unaffected. No differences exist regarding ECCN or HTSUS. All specified electrical and mechanical parameters match, with the exception of the height dimension. Select VI-2NJ-EX-B1 where active status is required and compliance requirements align.

Frequently Asked Questions (FAQ)

Q1: What criteria are strictly used for finding an equivalent or substitute DC DC converter in the VI-200™ (75W) series?
A1: Matching parameters include series, input and output voltage range, output current, power, isolation voltage, operating temperature, efficiency, mounting type, package case, dimensional compatibility, protection features, regulatory status (RoHS, REACH), and inventory status.

Q2: Is the VI-2NJ-EX-B1 a drop-in equivalent for VI-2NJ-EX?
A2: All electrical parameters, operating temperature range, package case, and mounting type are identical, with the only mechanical variation in the overall height dimension.

Q3: How does product status affect substitute selection?
A3: Selection is based on availability; VI-2NJ-EX is obsolete, making VI-2NJ-EX-B1, which is active, suitable where ongoing support is necessary.

Q4: Are there compliance or environmental consideration differences between VI-2NJ-EX and VI-2NJ-EX-B1?
A4: Both parts are RoHS non-compliant and REACH unaffected.

Q5: Does the package difference between 0.50" and 1.07" height impact substitution?
A5: Only the overall module height differs. All other mechanical parameters match.

Q6: Are special precautions needed for mounting or MSL (Moisture Sensitivity Level)?
A6: Both parts have through hole mounting and MSL classified as Not Applicable. No additional precautions are defined in the parameters provided.
