Substitute Part Grouping Explanation

Substitution of the AD7224KP is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute part, AD7224KPZ, maintains identical specifications across the following critical parameters:

• Resolution: 8-bit DAC architecture
• Output configuration: Single buffered voltage output channel
• Interface protocol: Parallel data input
• Reference input: External reference requirement
• Settling performance: 20µs maximum settling time
• Conversion architecture: R-2R ladder network
• Electrical operating ranges: Identical analog and digital supply voltage specifications
• Accuracy: Identical INL/DNL specifications (±1 LSB maximum)
• Package form factor: 20-PLCC (9x9) surface mount configuration
• Temperature operating range: -40°C to 85°C

The AD7224KPZ differs from the AD7224KP only in product status (Active vs. Obsolete) and packaging format (Tube vs. unspecified), with no changes to functional or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

The AD7224KPZ is the direct functional equivalent of the AD7224KP. Selection of AD7224KPZ is appropriate for new designs and component replacement applications due to its Active product status and current availability. The AD7224KPZ carries ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements for electronic component procurement.

For applications requiring the AD7224KP specifically, the AD7224KPZ provides identical electrical performance and mechanical compatibility without design modification. The transition from obsolete to active product status ensures long-term supply chain viability and manufacturing support.

Frequently Asked Questions (FAQ)

Q: Can AD7224KPZ replace AD7224KP in existing designs? A: Yes. The AD7224KPZ is electrically and mechanically identical to the AD7224KP. No circuit modifications or PCB redesign is required.
