Equivalent & Substitute Parts Reference for Vicor VI-J4J-CZ DC DC Converter

Part Overview

The Vicor VI-J4J-CZ is an isolated DC DC converter module providing 1 output of 36V at up to 694mA with a 55V to 100V input voltage range and 25W maximum power. It features a 3 kV isolation voltage, ITE (Commercial) application rating, OCP and SCP protection, 90% efficiency, through hole mounting, and a half brick package. The product status is obsolete, necessitating identification of substitute models that match the electrical, mechanical, and compliance parameters for continued use in compatible designs.

Key Parameters

Substitute Part Grouping Explanation

Substitute components are identified solely by comparing the provided parameters for compatibility. Only parts meeting the following strict criteria are considered:

• Series
• Type
• Number of Outputs
• Voltage - Input (Min/Max)
• Voltage - Output 1
• Current - Output (Max)
• Power (Watts)
• Voltage - Isolation
• Operating Temperature
• Efficiency
• Mounting Type
• Package / Case
• Features
• Compliance (RoHS, REACH, ECCN, HTSUS)
• Applications

No additional criteria are used. All substitutes must meet or exceed each of these parameters as per the provided input.

Parameter Comparison

Engineering Selection Recommendations

The substitute part VI-J4J-CZ-F1 matches all electrical and mechanical parameters of the obsolete VI-J4J-CZ, including voltage and current ratings, power output, isolation, protection features, operating temperature, mounting type, half brick package format, and compliance. Both parts share a RoHS non-compliant status, REACH unaffected status, and the same ECCN and HTSUS codes. Inventory status indicates availability of new original units for the substitute, supporting continued use in legacy designs subject to the same regulatory status.

Frequently Asked Questions (FAQ)

Q1: Which electrical parameters must match for substitution in this DC DC converter category?
All input and output voltage ratings, output current, power (Watts), isolation voltage, protection features, and efficiency must match exactly.

Q2: Are both main and substitute Vicor DC DC converters suitable for ITE (Commercial) applications?
Yes. Both VI-J4J-CZ and VI-J4J-CZ-F1 list ITE (Commercial) as their designated application type.

Q3: Does the mounting and package format affect substitute compatibility?
Yes. Both parts use through hole mounting and half brick package format. However, dimensions differ and should be verified within the mechanical constraints of the application.

Q4: Is compliance status (RoHS, REACH) identical for both parts?
Yes. Both are RoHS non-compliant, REACH unaffected, with matching ECCN and HTSUS codes.

Q5: How does product status impact selection?
The main part VI-J4J-CZ is obsolete. Selecting VI-J4J-CZ-F1 ensures continued availability while maintaining all specified performance and regulatory criteria.
