VI-J0K-CZ Equivalent & Substitute Parts Engineering Reference

Part Overview

The VI-J0K-CZ is a Vicor Corporation DC-DC converter from the VI-J00™ (25W) series, designed as an isolated module with 1 output, providing 40V at up to 625mA from a 10V to 20V DC input with 25W output power. This model is classified as obsolete, making it essential to identify equivalent or substitute parts with strictly matching electrical and mechanical parameters for ongoing product maintenance, system longevity, and direct component replacement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute part selection is based strictly on matching the provided electrical and mechanical parameters. The substitute part listed, VI-J0K-CZ-B1, originates from the same manufacturer and series as VI-J0K-CZ, ensuring compatibility in type, input and output voltage range, output current, output power, isolation, protection features (OCP, SCP), mounting type, and compliance statuses. Size and dimension differences are specified, but both maintain the Half Brick package requirement.

Parameter Comparison

Engineering Selection Recommendations

Selection of VI-J0K-CZ-B1 as a substitute for VI-J0K-CZ is appropriate when the original part is obsolete and continued use of RoHS non-compliant, REACH unaffected DC-DC converters is allowed in the application. Both parts share the identical compliance status, series, power rating, features, and mounting method, with the only variations being dimension values within the same package type (Half Brick) and product status (active versus obsolete).

Frequently Asked Questions (FAQ)

Q1: What key electrical parameters ensure the VI-J0K-CZ-B1 is a valid equivalent to the VI-J0K-CZ?
A1: Voltage input range (10V–20V), output voltage (40V), output current (625mA), power rating (25W), and voltage isolation (3kV) are all identical.

Q2: Are there any compliance or environmental differences between the VI-J0K-CZ and VI-J0K-CZ-B1?
A2: Both parts are RoHS non-compliant and REACH unaffected. No compliance differences are present based on provided data.

Q3: Are package or size differences relevant for direct substitution?
A3: Both parts use a Half Brick package type. Physical size may differ, so exact dimensions should be reviewed for mechanical fit within the enclosure.

Q4: Do both parts provide the same protection features?
A4: Yes. Both feature Overcurrent Protection (OCP) and Short Circuit Protection (SCP).

Q5: Can the substitute be used in the same operating temperature range as the main part?
A5: Yes. Both VI-J0K-CZ and VI-J0K-CZ-B1 have an operating temperature range of -25°C to +100°C.
