Key Parameters

Substitute Part Grouping Explanation

Substitute selection for DC-DC converter modules is determined by matching key electrical and mechanical parameters: input voltage range, output voltage, maximum output current, output power, isolation voltage, protection features, operating temperature, mounting type, and physical dimensions. These parameters are specified to ensure form, fit, and function equivalence. Compliance status, inventory, and product status are included strictly as provided.

Parameter Comparison

Engineering Selection Recommendations

Selection should be determined by product status and regulatory compliance. VI-B1N-EV is Obsolete and RoHS non-compliant; substitute part VI-B1N-EV-B1 is Active and also RoHS non-compliant. Both parts share identical electrical specifications, features, and certifications. REACH status and MSL are consistent across both parts. Inventory levels are provided for both parts. Dimension differences in height should be reviewed where mechanical clearance is a concern.

Frequently Asked Questions (FAQ)

Q1: What criteria are used to determine if VI-B1N-EV-B1 is an appropriate substitute for VI-B1N-EV?
A1: Substitution is based on matching input voltage range, output voltage, maximum output current, power rating, isolation voltage, operating temperature, mounting type, package, compliance status, inventory, and certifications.

Q2: Are VI-B1N-EV and VI-B1N-EV-B1 interchangeable in terms of electrical performance?
A2: Both parts provide equivalent electrical performance parameters as specified in the tables above.

Q3: What differences exist in the mechanical dimensions?
A3: Both parts share the same length and width, but VI-B1N-EV-B1 has a greater height (1.07" vs 0.50"). Mechanical fit in the target system should be verified based on this specification alone.

Q4: Is there any difference in compliance or regulatory status between the two parts?
A4: Both VI-B1N-EV and VI-B1N-EV-B1 are RoHS non-compliant and REACH unaffected. ECCN and HTSUS classifications are identical.

Q5: Is the mounting type the same for both parts?
A5: Both modules utilize Through Hole mounting and Full Brick package.

Q6: How should engineers approach selecting between these parts for legacy designs?
A6: When the original part is obsolete, selection should be made based on parameter equivalence and current product status. Inventory levels are relevant for procurement considerations.
