Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected when they match all electrical, mechanical, and functional parameters necessary for direct replacement. Primary selection criteria include: identical input voltage range, output voltage and current rating, power handling, isolation rating, protection features, mounting type, package dimensions or compatible form factor, and operational temperature. Only those parts matching every key parameter above are considered substitutes.

Parameter Comparison

Engineering Selection Recommendations

The primary driver for substituting the VI-22V-CW is its obsolete status. The substitute part VI-22V-CW-B1 matches the main part across all defined electrical, mechanical, and performance characteristics except for enclosure height. Both parts are RoHS non-compliant and have matching compliance certifications. Selection should be based on the Product Status and regulatory requirements, considering the similarity in physical, environmental, and safety parameters provided.

Frequently Asked Questions (FAQ)

Q1: What criteria are used for identifying substitute parts in the VI-200™ DC-DC converter category?
A1: Substitute parts are identified by matching input/output voltage, output current, power rating, isolation voltage, efficiency, protection features, package type, mounting style, operational temperature range, and size/dimensions as specified.

Q2: Are there any significant mechanical differences between VI-22V-CW and VI-22V-CW-B1?
A2: The only mechanical difference provided is in the height dimension: VI-22V-CW is 0.50" high, while VI-22V-CW-B1 is 1.07" high. All other footprint dimensions are identical.

Q3: Does the RoHS status differ between the main part and the substitute?
A3: No, both VI-22V-CW and VI-22V-CW-B1 are RoHS non-compliant.

Q4: Are features such as overcurrent, overtemperature, overvoltage, and short-circuit protection present in both parts?
A4: Yes, both parts include OCP, OTP, OVP, and SCP according to the provided data.

Q5: Is mounting interchangeability impacted?
A5: Both modules utilize through hole mounting in a full brick package, indicating mounting compatibility based on the input parameters.
