Equivalent & Substitute Parts Reference: Vicor VI-J4M-EZ DC-DC Converter

Part Overview

The Vicor VI-J4M-EZ is an Isolated Module DC-DC Converter designed for ITE (Commercial) applications. The converter provides a single 10V output at up to 2.5A with a wide input voltage range of 55V to 100V, 25W power output, and 3 kV isolation. It is housed in a half brick through-hole package with On/Off, OCP (Over Current Protection), and SCP (Short Circuit Protection) features. The VI-J4M-EZ is designated as obsolete by the manufacturer, making identification of suitable equivalent or substitute models necessary for equipment sustainment, repair, or redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitute DC-DC converters are selected based strictly on identical or matching key parameters, as required for the Isolated Module DC-DC Converter product category. Allowed parameters for substitution include: input voltage range (55V-100V), output voltage (10V), output current (2.5A), output power (25W), isolation voltage (3 kV), output count (1), efficiency (88%), features (OCP, SCP), operating temperature (-10°C to 100°C), mounting type (Through Hole), package/case (Half Brick), and manufacturer's certification and compliance attributes. All parameter values must match those of the main part or fall within the defined boundaries.

Parameter Comparison

Engineering Selection Recommendations

The Vicor VI-J4M-EZ is obsolete and RoHS non-compliant. Its listed substitute, the Vicor VI-J4M-EZ-F1, is active and RoHS non-compliant. Both units are classified as EAR99 for export, have the same series, electrical specifications, and compliance attributes except for an updated size/dimension in the substitute. Substitution can be based directly on product status (active vs. obsolete) and binary RoHS and ECCN criteria, consistent across both models.

Frequently Asked Questions (FAQ)

Q1: What electrical parameters are required for substituting the Vicor VI-J4M-EZ DC-DC Converter?
A1: Substitution requires matching input voltage range (55V-100V), output voltage (10V), output current (2.5A), output power (25W), voltage isolation (3 kV), number of outputs (1), and efficiency (88%).

Q2: Are the VI-J4M-EZ and VI-J4M-EZ-F1 compatible in terms of features and compliance?
A2: Both parts have identical features (OCP, SCP), RoHS status (non-compliant), and ECCN classification (EAR99).

Q3: Is there any mechanical difference between the main part and its substitute?
A3: Both models use a half brick through-hole package, but their size/dimensions differ. Vi-J4M-EZ measures 2.28" L x 2.40" W x 0.50" H while VI-J4M-EZ-F1 measures 2.28" L x 1.86" W x 0.79" H.

Q4: Does substitution affect operating temperature range or mounting method?
A4: Both parts operate from -10°C to 100°C and utilize through-hole mounting.

Q5: Is the substitute part compliant with current RoHS regulations?
A5: Both the main and substitute part are RoHS non-compliant.

Q6: How should inventory status influence selection?
A6: The main part (VI-J4M-EZ) is obsolete, making the substitute (VI-J4M-EZ-F1, active status) the preferred selection for designs requiring new procurement or continued support.
