Substitute Part Grouping Explanation

Substitution is determined strictly by matching key parameters such as input voltage range, output voltage and current, power rating, isolation voltage, package type, features, efficiency, operating temperature, mounting type, and compliance. For isolated DC-DC converter modules, both electrical and mechanical specifications must be identical for a part to be considered a legitimate substitute.

Engineering Selection Recommendations

Main part VI-B7H-CW is classified as obsolete, whereas substitute part VI-B7H-CW-B1 is active and available. Both parts are RoHS non-compliant and unaffected by REACH. ECCN and HTSUS codes are identical, and moisture sensitivity level is not applicable. Selection is governed by product status and certifications provided in the parameters.

Frequently Asked Questions (FAQ)

Q1: What are the electrical parameters that must match for DC-DC converter substitutions?
A1: Input voltage range, output voltage, output current, rated power, isolation voltage, and application type are mandatory match criteria.

Q2: Is package size or case type relevant in substitution?
A2: Package style and dimensions must correspond to ensure mechanical compatibility and successful mounting.

Q3: How does RoHS or REACH compliance affect part selection?
A3: Both VI-B7H-CW and VI-B7H-CW-B1 are RoHS non-compliant. REACH status is unaffected. Selection must adhere to the compliance status stated.

Q4: Can substitute parts with different thickness within the same case style be used interchangeably?
A4: Only the specific dimensions provided determine compatibility. The substitute part VI-B7H-CW-B1 has increased height, which may impact mechanical fit.

Q5: Is product status a critical selection parameter?
A5: Yes. When the main part is obsolete, an active part with identical key parameters and compliance status is required for substitution.
