Equivalent & Substitute Parts Reference: Vicor VI-25F-CX
Part Overview
The Vicor VI-25F-CX is an isolated module DC-DC converter designed for commercial ITE applications, featuring a single output of 72V at 1.04A from a 100V–200V input range and providing 75W power. The product is obsolete, making it necessary to identify substitute models for continued production support, maintenance, or replacement needs.

Substitute Part Grouping Explanation
Substitute parts are grouped strictly based on matching electrical and mechanical parameters. The key substitution criteria are:
- Manufacturer consistency (Vicor Corporation)
- Identical series and part family (VI-200™ (75W))
- Same input and output ratings (voltage, current, power)
- Matching isolation voltage, number of outputs, application suitability, and protection features
- Equivalent operating temperature range and efficiency
- Same mounting type and package / case format
- Compliance fields (RoHS, REACH, ECCN) considered only as provided in the input

Engineering Selection Recommendations
Selection between VI-25F-CX and VI-25F-CX-B1 is dictated by product status and available certifications. VI-25F-CX is obsolete, while VI-25F-CX-B1 is active. Both models are RoHS non-compliant and REACH unaffected; these compliance statuses must be considered in regulated environments. ECCN and HTSUS codes remain unchanged for both parts. No electrical or mechanical compatibility deviations are present except dimensional height, which should be reviewed for system mechanical fit.
Frequently Asked Questions (FAQ)
Q1: What parameters are critical for substituting the Vicor VI-25F-CX?
Key factors include identical input/output voltages, output current, power rating, isolation voltage, application type, operating temperature, features, mounting type, and package / case.
Q2: Are there mechanical differences between VI-25F-CX and VI-25F-CX-B1?
Yes, the physical height differs: VI-25F-CX is 0.50" high, whereas VI-25F-CX-B1 is 1.07" high. Both share the same footprint and package format.
Q3: Are the certifications and compliance statuses the same?
Both parts are RoHS non-compliant, REACH unaffected, and have the same ECCN and HTSUS codes.
Q4: Is the substitute VI-25F-CX-B1 still in production?
VI-25F-CX-B1 is listed as active, while VI-25F-CX is obsolete.
Q5: Do electrical parameters differ between the two parts?
No. Input and output voltages, current, power, features, and efficiency are identical.
Q6: What should be considered regarding package compatibility?
Confirm that the dimensional height of VI-25F-CX-B1 (1.07") can be accommodated in the target assembly, as it differs from the main part (0.50").
