VI-J4K-CZ Equivalent & Substitute Parts Reference

Part Overview

The Vicor Corporation VI-J4K-CZ is an isolated DC-DC converter module featuring a single output of 40V at 625mA with a power rating of 25W. It is designed for ITE (Commercial) applications and incorporates overcurrent protection (OCP) and short-circuit protection (SCP). The module operates within an input voltage range of 55V to 100V and provides a 3 kV isolation barrier. The product status for VI-J4K-CZ is "Obsolete," necessitating identification and evaluation of equivalent or substitute models for ongoing designs and maintenance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute part selection for VI-J4K-CZ is based strictly on matching the foundational parameters: output voltage (40V), output current (625mA), input voltage range (55V–100V), power rating (25W), isolation voltage (3 kV), output quantity (1), efficiency (90%), electrical features (OCP, SCP), operating temperature range (–25°C to 100°C), mounting type (Through Hole), and package/case type (Half Brick). Only parts aligning precisely with these characteristics are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

The VI-J4K-CZ-F1 DC-DC converter from Vicor Corporation matches all provided electrical and mechanical parameters of the obsolete VI-J4K-CZ model. Both devices share the same input and output voltage ranges, output current, efficiency, protection features, and mounting style. Key compliance and regulatory statuses—including RoHS non-compliance, REACH unaffected, ECCN EAR99, and HTSUS 8504.40.9580—are consistent between both the obsolete and active models. Dimensional variations should be noted for design integration. Only substitute parts meeting all specified criteria and regulatory statuses are considered equivalent.

Frequently Asked Questions (FAQ)

Q1: Which parameters must be identical for a substitute part to be used in place of VI-J4K-CZ?
A1: Output voltage, output current, input voltage range, isolation voltage, power rating, protection features, efficiency, operating temperature range, number of outputs, mounting type, package type, compliance statuses, and size/dimensions must match.

Q2: Is VI-J4K-CZ-F1 dimensionally identical to VI-J4K-CZ?
A2: Both are Half Brick through-hole modules but have different dimensions: VI-J4K-CZ (2.28" x 2.40" x 0.50") and VI-J4K-CZ-F1 (2.28" x 1.86" x 0.79"). Mechanical fit in the application should be evaluated using only the provided information.

Q3: Do both parts support the same compliance and certification requirements?
A3: VI-J4K-CZ and VI-J4K-CZ-F1 are RoHS non-compliant, REACH unaffected, and classified as EAR99 under ECCN, with HTSUS 8504.40.9580.

Q4: Does a change from "Obsolete" to "Active" status affect interchangeability?
A4: The active status of VI-J4K-CZ-F1 allows ongoing procurement, whereas VI-J4K-CZ is only available from residual inventory. Substitution is based solely on matching electrical, mechanical, and compliance parameters.

Q5: Are installation procedures impacted by differences in package dimensions?
A5: Installation in existing designs should consider the dimensional differences indicated for each Half Brick module and ensure compatibility with the intended application using only the specified mounting type and package details.
