AD667KP Equivalent & Substitute Parts

Part Overview

The AD667KP is a 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc., designed for data acquisition applications requiring voltage output conversion. This component features a single DAC channel with buffered voltage output, parallel data interface, and support for both external and internal reference configurations. The AD667KP is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitute parts for the AD667KP are identified based on strict electrical and mechanical parameter matching. The primary substitution criterion is functional equivalence across all critical parameters: 12-bit resolution, single DAC channel, buffered voltage output, parallel data interface, 4µs settling time, R-2R architecture, identical supply voltage range (±11.4V ~ 16.5V), matching INL/DNL specifications (±0.25 LSB), and identical package configuration (28-LCC J-Lead surface mount).

The AD667KPZ qualifies as a direct substitute because it maintains all electrical specifications and mechanical compatibility with the original AD667KP. The key differentiator is product status: AD667KPZ is active and available, whereas AD667KP is obsolete. Both parts share the same base product number (AD667) and are manufactured by Analog Devices Inc.

Parameter Comparison

Engineering Selection Recommendations

The AD667KPZ is the direct equivalent for the obsolete AD667KP. Both components are manufactured by Analog Devices Inc. and provide identical electrical performance and mechanical compatibility. Selection between these parts is determined by availability and product status rather than technical performance.

For new designs or system replacements, AD667KPZ is the appropriate choice due to its active product status and current availability. The AD667KPZ carries ROHS3 compliance and REACH unaffected status, meeting modern environmental and regulatory requirements.

The difference in Moisture Sensitivity Level (MSL 1 versus MSL 3) reflects packaging differences: AD667KP uses standard packaging with unlimited shelf life, while AD667KPZ uses tube packaging with 168-hour moisture exposure limits. This distinction affects storage and handling procedures but does not impact electrical performance or functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can AD667KPZ directly replace AD667KP in existing designs? A: Yes. The AD667KPZ is electrically and mechanically identical to the AD667KP. All electrical parameters, pin configurations, and functional specifications match exactly. Direct substitution is possible without circuit modifications.

Q: What is the difference between AD667KP and AD667KPZ? A: The primary differences are product status and packaging. AD667KP is obsolete; AD667KPZ is active. AD667KP uses standard packaging (MSL 1), while AD667KPZ uses tube packaging (MSL 3). Electrical specifications are identical.

Q: Are there any compliance differences between these parts? A: AD667KPZ includes ROHS3 compliance and REACH unaffected status certifications. AD667KP specifications do not include these certifications. Both parts carry the same ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Q: What does MSL 3 (168 Hours) mean for AD667KPZ? A: Moisture Sensitivity Level 3 indicates the component can be exposed to moisture for up to 168 hours before soldering. Proper storage in dry conditions and handling procedures are required. This is standard for tube-packaged surface mount components.

Q: Is the 28-PLCC package the same for both parts? A: Yes. Both AD667KP and AD667KPZ use the 28-LCC (J-Lead) package with dimensions 11.51x11.51mm. PCB footprints and mounting procedures are identical.

Q: Can I use AD667KPZ in applications originally designed for AD667KP? A: Yes. The AD667KPZ is a direct functional equivalent. No design changes, circuit modifications, or firmware updates are required. Existing PCB layouts and schematics remain valid.
