Equivalent & Substitute Parts Reference for Vicor VI-B1L-CX

Part Overview

The Vicor VI-B1L-CX is an isolated module DC DC converter designed for ITE (Commercial) applications. It features a single output of 28V at a maximum current of 2.68A, with an input voltage range of 21V to 32V and 3 kV isolation. The product status is Obsolete, making it necessary to identify substitute parts for continued production, maintenance, or repair. Alternative models are sought to ensure compatibility with existing designs and to address long-term availability concerns.

Substitute Part Grouping Explanation

Substitute parts have been identified by matching all core electrical and mechanical parameters: input voltage range, output voltage, maximum output current, power rating, isolation voltage, module type, mounting type, package/case form factor, operating temperature range, and regulated features. Only parts with the same configuration, dimensional matching, and compliance attributes are considered. Part grouping is strictly based on equivalence in these fields.

Engineering Selection Recommendations

When selecting substitutes for the Vicor VI-B1L-CX, both the primary part and the substitute VI-B1L-CX-B1 match on all major electrical, mechanical, and regulatory parameters, except for the physical height dimension. Both components are RoHS non-compliant and REACH Unaffected, retaining consistent certification and compliance status. Product status should be prioritized for long-term supply assurance.

Frequently Asked Questions (FAQ)

Q1: What substitution criteria are used for VI-B1L-CX?

Substitution is based on matching key parameters, including input voltage range, output voltage, current rating, power, isolation voltage, type, output configuration, mounting type, package case, operating temperature, features, and compliance attributes.

Q2: Are VI-B1L-CX and VI-B1L-CX-B1 interchangeable in existing designs?

Electrical and compliance parameters are identical. The package dimensions differ in height (0.50" vs. 1.07"). Mechanical compatibility with the PCB and enclosure must be confirmed for the increased height.

Q3: Does the substitute maintain regulatory compliance?

Both VI-B1L-CX and VI-B1L-CX-B1 are RoHS non-compliant, REACH Unaffected, and hold the same ECCN and HTSUS codes.

Q4: What are the main considerations when selecting VI-B1L-CX-B1 as a substitute?

Consider product status, inventory, exact matching of electrical and mechanical parameters, and regulatory compliance. Dimensional differences must be accommodated within the end application.
