VI-26H-CX Equivalent & Substitute Parts

Part Overview

The Vicor Corporation VI-26H-CX is an Isolated Module DC-DC Converter from the VI-200™ (75W) series. It features 1 output at 52V 1.44A with an input range of 200V to 400V, delivering up to 75 W with 3 kV isolation and multiple protection features (OCP, OTP, OVP, SCP). Its package type is Full Brick, and it is designed for ITE (Commercial) applications. The VI-26H-CX is listed as obsolete, necessitating alternative component selection for both ongoing and new designs requiring its particular electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute part selection for DC-DC converters of this category must match all critical functional, electrical, and mechanical parameters. Substitution is permissible only when the following parameters are identical: input voltage range, output voltage, output current, power rating, isolation voltage, package type, mounting method, and feature set. Regulatory compliance, product status, and certifications provided must also be evaluated for alignment. These parameters have been explicitly provided and are the sole basis for substitution in this selection.

Key parameters for DC-DC converter substitution:

• Electrical: Voltage - Input (Min/Max), Voltage - Output, Current - Output (Max), Power (Watts), Voltage - Isolation, Efficiency
• Mechanical: Mounting Type, Package / Case, Size / Dimension
• Functional: Number of Outputs, Applications, Features, Operating Temperature
• Compliance: RoHS Status, MSL, REACH Status, ECCN, HTSUS
• Product status

Parameter Comparison

Engineering Selection Recommendations

The VI-26H-CX is categorized as obsolete, while the VI-26H-CX-B1 is active and meets all identical electrical, mechanical, and compliance parameters. Both parts are RoHS non-compliant and unaffected by REACH status. The substitute offers alignment in all regulatory and certification listings (ECCN: EAR99, HTSUS: 8504.40.9580). Dimensional and package differences are limited to height, which must be considered for mechanical compatibility in existing designs.

Frequently Asked Questions (FAQ)

Q1: Which parameters are critical for substituting the VI-26H-CX DC-DC converter?

• Only the explicitly listed input voltage range, output voltage, output current, power rating, isolation voltage, mounting type, package/case, features, efficiency, operating temperature, regulatory compliance, and physical dimensions are used to qualify substitutes.

Q2: Does VI-26H-CX-B1 offer direct electrical compatibility with VI-26H-CX?

• Yes. All electrical characteristics including input/output voltage ranges, current, power rating, isolation voltage, efficiency, protection features, and operating temperature are identical.

Q3: Are there mechanical differences between VI-26H-CX and VI-26H-CX-B1?

• Yes. The overall length and width are the same, while the height differs: 0.50" vs 1.07". This must be considered if mechanical envelope or clearance is a design constraint.

Q4: Is the substitute part RoHS compliant?

• It is RoHS non-compliant, matching the main part's compliance status.

Q5: What regulatory and exporting classifications apply to these parts?

• Both carry identical ECCN (EAR99) and HTSUS (8504.40.9580) classifications.

Q6: What is the recommended substitute if mechanical envelope can accommodate the increased height?

• VI-26H-CX-B1 is the substitute matching all explicit functional and compliance parameters, with noted dimensional height difference.
