Equivalent & Substitute Parts Reference: Vicor VI-26D-CX DC DC Converter

Part Overview

Manufacturer Part Number: VI-26D-CX
The Vicor VI-26D-CX is an isolated module DC-DC converter featuring a single 85V output at 882mA, designed for input voltages between 200V and 400V. The module provides 75W output power with 3 kV isolation and includes standard protection features such as OCP, OTP, OVP, and SCP. It is housed in a full brick through-hole package with dimensions of 4.60" L x 2.40" W x 0.50" H. This product is currently classified as obsolete, making it necessary to identify alternative models with strictly compatible electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute or equivalent parts are grouped strictly by matching the following key parameters: manufacturer part number, input voltage range, output voltage, output current, isolation voltage, output power, protection features, operating temperature, efficiency, mounting type, package form factor, RoHS status, and mechanical size. Only parts meeting all these specified criteria within the product category can be considered substitutes for the VI-26D-CX DC-DC converter.

Parameter Comparison

Engineering Selection Recommendations

Substitute parts are selected based on equivalent electrical and mechanical parameters, matching certifications, and compliance statuses. The VI-26D-CX-B1 provides identical electrical specifications and regulatory information. The main difference is in the physical height of the package (0.50" vs. 1.07" H), which may impact system integration where height constraints are critical. Both parts are RoHS non-compliant and REACH unaffected. The product status for VI-26D-CX is obsolete, while VI-26D-CX-B1 is active, making the latter suitable for continued use where regulatory and form factor criteria are met.

Frequently Asked Questions (FAQ)

Q1: What parameters must match for a DC DC converter to be considered a substitute?
A1: Input voltage range, output voltage, output current, isolation voltage, power rating, operating temperature, efficiency, mounting type, package form factor, protection features, RoHS status, and size must all match.

Q2: What is the primary difference between VI-26D-CX and VI-26D-CX-B1?
A2: The only difference is the package height: VI-26D-CX is 0.50" H, while VI-26D-CX-B1 is 1.07" H. All other electrical and compliance parameters are identical.

Q3: Does the substitute part VI-26D-CX-B1 meet the same compliance requirements as VI-26D-CX?
A3: Yes, both parts have the same RoHS status (non-compliant), REACH status (unaffected), ECCN, and HTSUS codes.

Q4: Are there any performance differences between VI-26D-CX and VI-26D-CX-B1?
A4: There are no performance differences based on the provided parameters; both deliver the same electrical characteristics.

Q5: Is the mounting type compatible between the original and substitute parts?
A5: Both parts use the same through-hole mounting type and full brick package style, making them compatible except for height constraints.

Q6: Should package height differences be considered for mechanical fit?
A6: Yes, ensure that the system can accommodate the increased height of the substitute part if height is a critical constraint.
