VI-B5F-MU Equivalent & Substitute Parts Reference

Part Overview

The Vicor Corporation VI-B5F-MU is an isolated DC-DC converter module, categorized under full brick power supplies with a single 72V/2.78A output, input range of 100–200V DC, and a total output power of 200W. The device offers output isolation of 3 kV, through-hole mounting, and incorporates output protection features such as overcurrent (OCP), overtemperature (OTP), overvoltage (OVP), and short-circuit protection (SCP). The product is marked obsolete, making identification of direct substitutes necessary for active designs, maintenance, and repairs.

Key Parameters

Substitute Part Grouping Explanation

Substitution is strictly determined by identical key electrical and mechanical parameters, including input voltage range, output voltage and current, isolation voltage, efficiency, protection features, package type, mounting type, and environmental ratings. Compliance and status parameters such as RoHS, REACH, and ECCN are also matched as per the provided information. Differences in size or inactive product status are highlighted for engineering review.

Parameter Comparison

Engineering Selection Recommendations

Selection between VI-B5F-MU and VI-B5F-MU-B1 shall be based on product availability and active status. Both are RoHS non-compliant, share identical compliance statuses, and have matching key electrical and operational parameters. Mechanical differences in height (0.50" vs. 1.07") must be reviewed for physical fit and thermal management within the application.

Frequently Asked Questions (FAQ)

Q: Are VI-B5F-MU and VI-B5F-MU-B1 electrically compatible as DC-DC converter module substitutes?
A: Both modules have identical electrical parameters, including input/output ranges, power rating, isolation voltage, protection features, and efficiency.

Q: Do the size and mounting type differ between VI-B5F-MU and VI-B5F-MU-B1?
A: Both are full brick, through-hole modules. The primary size difference is in height (0.50" for VI-B5F-MU; 1.07" for VI-B5F-MU-B1).

Q: Is there any difference in environmental, compliance, or regulatory status between the two modules?
A: Both modules are RoHS non-compliant, REACH unaffected, and share the same ECCN and HTSUS codes.

Q: Can VI-B5F-MU-B1 replace VI-B5F-MU in legacy designs?
A: Substitution is feasible with regard to electrical and compliance parameters. Physical fit must be evaluated due to the difference in module height.

Q: Are both modules suitable for ITE (Commercial) applications as per their categorization?
A: Yes, both are specified for ITE (Commercial) use in the provided parameters.
