Substitute Part Grouping Explanation

Substitution eligibility for the ADM1023ARQZ is determined by strict equivalence across the following critical parameters:

• Base product number (ADM1023)
• Sensor topology (Internal and External dual-sensor configuration)
• Temperature sensing range (0°C ~ 120°C)
• Accuracy specifications (±1°C Local, ±3°C Remote)
• Output interface (SMBus with alarm output)
• Supply voltage range (3V ~ 5.5V)
• Package form factor (16-SSOP)
• Mounting technology (Surface Mount)

The ADM1023ARQZ-REEL qualifies as a direct substitute based on identical electrical and mechanical specifications. The distinction between these part numbers lies exclusively in packaging configuration: the main part number uses standard packaging, while the substitute uses Tape & Reel (TR) packaging for automated assembly environments.

Parameter Comparison

Engineering Selection Recommendations

The ADM1023ARQZ-REEL is the qualified substitute for the obsolete ADM1023ARQZ. Both components share identical electrical specifications, thermal characteristics, and mechanical form factors. The primary distinction is product status: the substitute maintains active manufacturing status with onsemi, ensuring continued availability and supply chain reliability.

Selection between these part numbers should be based on procurement requirements and assembly methodology. The standard ADM1023ARQZ packaging is suitable for manual assembly or low-volume applications, while the ADM1023ARQZ-REEL Tape & Reel configuration is optimized for high-volume automated pick-and-place assembly processes.

Both variants comply with REACH regulations and carry identical moisture sensitivity ratings. The substitute part demonstrates superior compliance posture through active product status, making it the preferred choice for new designs and ongoing production support.

Frequently Asked Questions (FAQ)

Q: Can ADM1023ARQZ-REEL be used as a direct replacement for ADM1023ARQZ?

A: Yes. Both components are electrically and mechanically identical. The only difference is packaging configuration: standard versus Tape & Reel. Functional performance, thermal characteristics, and interface specifications are equivalent.

Q: What is the difference between standard packaging and Tape & Reel (TR) packaging?

A: Standard packaging is used for manual assembly or low-volume procurement. Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for automated assembly equipment. The component itself is identical; only the delivery format differs.

Q: Why is the main part number listed as obsolete?

A: The ADM1023ARQZ has reached end-of-life status with onsemi. The ADM1023ARQZ-REEL maintains active production status and serves as the current manufacturing equivalent for ongoing applications.

Q: Are there any compliance differences between these part numbers?

A: No. Both components carry identical REACH status (REACH Unaffected), moisture sensitivity ratings (MSL 1), and regulatory classifications (ECCN EAR99, HTSUS 8542.39.0001).

Q: What assembly method should determine my part number selection?

A: For manual assembly or prototype applications, either part number is acceptable. For high-volume production with automated pick-and-place equipment, the ADM1023ARQZ-REEL Tape & Reel configuration is the standard choice.

Q: Are the temperature sensing specifications identical?

A: Yes. Both components provide 0°C to 120°C external sensor monitoring with ±1°C local accuracy and ±3°C remote accuracy. SMBus output and alarm functionality are identical.
