Key Parameters

Substitute Part Grouping Explanation

Substitution of the AD8170ANZ is determined by the following critical parameters:

• Functional Equivalence: Both the main part and substitute must perform multiplexer with amplifier interface functions
• Supply Voltage Compatibility: Operating range of ±4V ~ 6V must be maintained
• Base Product Number: Parts sharing the AD8170 base product number are functionally equivalent
• Regulatory Compliance: ECCN and HTSUS classifications must align for trade and export purposes
• Moisture Sensitivity: MSL rating of 1 (Unlimited) applies across the product family

The AD8170ARZ qualifies as a direct functional substitute, sharing the same base product number, supply voltage range, application category, and regulatory classifications. The primary difference is packaging format: the main part uses through-hole 8-DIP mounting, while the substitute uses surface-mount 8-SOIC packaging.

Parameter Comparison

Engineering Selection Recommendations

The AD8170ARZ is the direct substitute for the AD8170ANZ. Both parts maintain identical electrical specifications, supply voltage requirements, and regulatory classifications. The AD8170ARZ offers the advantage of active product status, ensuring continued availability and manufacturing support.

Selection between these parts depends on board design requirements:

• Through-hole applications: The AD8170ANZ 8-DIP package is suitable for legacy designs or boards with through-hole assembly processes
• Surface-mount applications: The AD8170ARZ 8-SOIC package is appropriate for modern PCB designs utilizing surface-mount technology
• New designs: The AD8170ARZ is recommended due to its active product status and ROHS3 compliance certification

Both parts are classified under ECCN EAR99 and HTSUS 8542.39.0001, maintaining identical export and trade compliance profiles.

Frequently Asked Questions (FAQ)

Q: Can the AD8170ARZ directly replace the AD8170ANZ in existing designs?

A: Electrical and functional compatibility is confirmed. However, board-level integration requires assessment of mounting technology. Through-hole designs require redesign for surface-mount substitution, while surface-mount designs can directly accommodate the AD8170ARZ.

Q: What is the primary difference between these two parts?

A: The AD8170ANZ uses 8-DIP through-hole packaging (0.300" width), while the AD8170ARZ uses 8-SOIC surface-mount packaging (0.154" width). All electrical parameters, supply voltage ranges, and functional specifications remain identical.

Q: Why is the AD8170ANZ classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The AD8170ARZ, with active product status, represents the current manufacturing equivalent and is recommended for new designs.

Q: Are there compliance differences between these parts?

A: Both parts share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. The AD8170ARZ includes ROHS3 compliance certification, which is not specified for the AD8170ANZ.

Q: What is the moisture sensitivity level for these components?

A: Both the AD8170ANZ and AD8170ARZ carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
