Engineering Selection Recommendations
The VI-J7T-CY is categorized as Obsolete, while the VI-J7T-CY-F1 is Active. Both parts maintain an identical electrical profile, with consistent ratings and feature sets. Both are RoHS non-compliant and REACH unaffected. Given both modules’ non-compliance with RoHS, selection should remain within applications where this compliance is not required. The VI-J7T-CY-F1 is suitable for substitution strictly on the basis of availability and matching certifications and product status.
Frequently Asked Questions (FAQ)
Q: What criteria must substitute DC-DC converters meet for equivalency with VI-J7T-CY?
A: Substitute parts must match all key operational parameters such as series, input voltage range, output voltage and current, power rating, isolation voltage, mounting type, and environmental and regulatory status.
Q: Can the VI-J7T-CY-F1 be used as a direct replacement for VI-J7T-CY?
A: Yes. VI-J7T-CY-F1 matches all specified electrical, mechanical, and compliance parameters, qualifying as a direct substitute.
Q: Are there any considerations regarding footprint and mounting?
A: Both parts use a Half Brick package and Through Hole mounting. Verify dimensional compatibility regarding board layout as the VI-J7T-CY-F1 has different width and height.
Q: Is RoHS compliance affected by substituting VI-J7T-CY with VI-J7T-CY-F1?
A: Both parts are RoHS non-compliant, so there is no change in compliance status when substituting.
Q: Does product status affect substitution selection?
A: Yes. The VI-J7T-CY is Obsolete, while the substitute VI-J7T-CY-F1 is Active, supporting ongoing availability for new designs or replacements.
Q: Are certification and regulatory parameters matched?
A: Both parts are REACH unaffected and have the same ECCN classification. Compliance parameters are identical.
