Engineering Selection Recommendations
The VI-22N-EX is obsolete. The VI-22N-EX-F2 is active and matches all provided electrical and regulatory parameters. Both parts are RoHS non-compliant with REACH unaffected status and Moisture Sensitivity Level not applicable. ECCN and HTSUS classifications are the same. Package type is full brick through hole; however, size/dimensions differ and must be confirmed for mechanical fit. No additional technical or compliance criteria are available in the provided data.
Frequently Asked Questions (FAQ)
Q1: What are the key criteria for substituting the VI-22N-EX DC-DC converter?
A1: Key substitution criteria are identical input voltage range, output voltage and current, power rating, isolation voltage, efficiency, features, operating temperature, compliance status (RoHS, REACH), and mounting package.
Q2: Is the VI-22N-EX-F2 functionally identical to the VI-22N-EX?
A2: All specified electrical, environmental, and compliance parameters match between the two parts. The only difference in the provided data is their size/dimension.
Q3: Can the VI-22N-EX-F2 be directly replaced in all applications where VI-22N-EX was used?
A3: Electrical and application parameters align. The mechanical fit depends on the package dimensions; users should confirm compatibility with the existing mechanical layout.
