Engineering Selection Recommendations

The ICL7622DCPD+ serves as the direct functional equivalent to the obsolete ICL7622DCPD. Selection between these parts is determined by regulatory and procurement requirements rather than electrical performance.

For New Designs and Ongoing Production: The ICL7622DCPD+ is the appropriate selection. This part maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. The transition from RoHS non-compliant to ROHS3 compliant status reflects current manufacturing standards and regulatory requirements.

For Legacy System Support: The ICL7622DCPD remains available in inventory (2000 units) for applications where existing documentation or qualification specifically references the original part number. The ICL7622DCPD+ provides an alternative path for procurement when the original part becomes unavailable.

Packaging Consideration: The ICL7622DCPD+ is supplied in Tube packaging, whereas the original part number does not specify packaging format. Both parts utilize identical 14-PDIP through-hole package geometry and are mechanically interchangeable on printed circuit boards.

Frequently Asked Questions (FAQ)

Q: Can the ICL7622DCPD+ be used as a direct replacement for the ICL7622DCPD?

A: Yes. The ICL7622DCPD+ is electrically and mechanically identical to the ICL7622DCPD across all specified parameters. Both devices feature identical slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, supply voltage range, and operating temperature specifications.
