Replacement verdict
Compatible functional replacement candidate
The AD8170ARZ and AD8170AR-REEL7 are functionally equivalent, sharing the same 8-lead SOIC package, 2:1 multiplexer architecture, and specified operating temperature range. The only meaningful distinction is packaging format: the AD8170ARZ is supplied in tube form, while the AD8170AR-REEL7 is supplied on tape and reel for automated assembly. Either part can serve as a direct functional substitute for the other, with the choice driven by production handling requirements rather than electrical or mechanical differences.

Frequently asked questions
What is the difference between AD8170ARZ and AD8170AR-REEL7?
Both parts are the same AD8170 8-lead SOIC (R-8) analog multiplexer IC. The AD8170ARZ is the standard tube/rail packaging orderable part number, while AD8170AR-REEL7 is the same die and package supplied on a 7-inch tape-and-reel carrier for automated assembly. The "Z" suffix on AD8170ARZ denotes RoHS-compliant lead finish per Analog Devices nomenclature.
Are AD8170ARZ and AD8170AR-REEL7 electrically and functionally identical?
Yes. Both orderable part numbers refer to the same AD8170 device in the 8-lead SOIC package, so the electrical specifications, pinout, and functional behavior are identical. The only documented difference is the shipping/packaging format (tube vs. 7-inch tape-and-reel).
What is the AD8170 and what are its key verified parameters?
The AD8170 is a high-speed, low-power 2:1 analog multiplexer with an integrated output amplifier, manufactured by Analog Devices. Verified datasheet parameters include a -3 dB bandwidth of 250 MHz (G = +2), 0.1 dB gain flatness to 70 MHz, a slew rate of 1000 V/µs, and operation on ±5 V or single +5 V supplies. It is specified for the industrial temperature range of -40°C to +85°C.
Can AD8170ARZ and AD8170AR-REEL7 be used interchangeably in a design?
Yes, from an electrical and footprint standpoint they are interchangeable because they are the same device in the same 8-lead SOIC package. The choice between them is a manufacturing/logistics decision: AD8170ARZ is supplied in tubes, and AD8170AR-REEL7 is supplied on 7-inch tape-and-reel for pick-and-place assembly.
What package does the AD8170ARZ / AD8170AR-REEL7 use?
Both part numbers use the 8-lead SOIC package (Analog Devices package code R-8), with a body width of 3.90 mm (0.154 in) and 1.27 mm lead pitch. This package is compatible with standard SOIC-8 PCB land patterns.
Does the "Z" suffix on AD8170ARZ indicate RoHS compliance?
Yes. Per Analog Devices part-numbering conventions, the "Z" suffix designates a RoHS-compliant part with a lead-free (matte tin) finish. Designers should confirm the specific orderable part number's compliance status against the current manufacturer datasheet or product page before final qualification.
What supply voltage and temperature range do these parts support?
The AD8170 operates from dual ±5 V supplies or a single +5 V supply, and both AD8170ARZ and AD8170AR-REEL7 are specified over the industrial temperature range of -40°C to +85°C. These parameters are identical for both orderable part numbers because they are the same silicon device.
Which part number should be selected for high-volume automated assembly?
AD8170AR-REEL7 is the appropriate choice for high-volume automated pick-and-place assembly because it is supplied on 7-inch tape-and-reel. AD8170ARZ in tubes is typically used for prototyping, low-volume runs, or manual assembly. Selection should be based on the assembly line's feeder and packaging requirements.
