Key Parameters

Substitute Part Grouping Explanation

Substitute part selection for the Vicor VI-B7L-MX DC DC converter is strictly based on matching crucial parameters: input voltage range (100V–375V), output voltage and current ratings (28V, 2.68A, 75W), isolation (3kV), operating temperature (-55°C to 85°C), electrical efficiency (90%), through-hole mounting, full brick package, and protection features. Compliance, inventory status, and dimensions are included as allowed by category specifications.

Parameter Comparison

Engineering Selection Recommendations

Selection between the Vicor VI-B7L-MX and VI-B7L-MX-B1 DC DC converters is determined by product status and regulatory compliance. VI-B7L-MX is obsolete; substitution by VI-B7L-MX-B1 is supported due to identical electrical and isolating parameters, application category, compliance status, and series grouping. Dimensional differences in height must be considered for mechanical integration.

Frequently Asked Questions (FAQ)

Q1: What substitution criteria are applied for Vicor DC DC converters in this category? A: Substitution is strictly based on input and output voltages, output current, total power rating, isolation voltage, operating temperature range, features, mounting method, package type, and regulatory compliance.

Q2: Are the electrical parameters of VI-B7L-MX and VI-B7L-MX-B1 identical? A: Yes, input voltage, output voltage, output current, isolation, efficiency, and operating temperature are identical.

Q3: Does the substitute part have a different package size? A: Yes, the VI-B7L-MX-B1 has a greater package height (1.07") compared to VI-B7L-MX (0.50"). Length and width are the same.

Q4: Is product status a critical factor in substitution? A: Yes, VI-B7L-MX is obsolete; VI-B7L-MX-B1 is active, which is important for sourcing and lifecycle planning.

Q5: Are there differences in compliance or certifications between the two parts? A: Both parts share identical RoHS non-compliance, REACH status, ECCN, and HTSUS codes.

Q6: Should mounting type be checked when substituting? A: Both parts use through-hole mounting, which supports compatibility for PCB assembly. Only the height dimension varies.
