Engineering Selection Recommendations

The AD7655ACPZ serves as a direct substitute for the AD7655ACPZRL. Both parts are identical in electrical specifications, pin configuration, and package format. The primary distinction is product status and packaging format:

  • AD7655ACPZRL: Obsolete status, supplied in Reel packaging
  • AD7655ACPZ: Active status, supplied in Tray packaging

The AD7655ACPZ is the recommended selection for new designs and ongoing production due to its Active product status, ensuring continued manufacturer support and supply chain availability. For existing designs currently using the AD7655ACPZRL, direct substitution with AD7655ACPZ is electrically and mechanically compatible without design modification.

The AD7655ACPZ maintains ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic components in industrial and commercial applications.

Frequently Asked Questions (FAQ)
