Replacement verdict
Compatible functional replacement candidate
The AD8170ARZ and AD8170AR-REEL are functionally equivalent implementations of the same AD8170 8-lead SOIC multiplexer-amplifier, differing only in packaging format and ordering quantity. Both share identical die, pinout, electrical specifications, and operating conditions, making them interchangeable in a given design provided the tape-and-reel or tube delivery format aligns with the assembly process.

Frequently asked questions
What is the difference between AD8170ARZ and AD8170AR-REEL?
Both parts are the same AD8170 8-lead SOIC (R-8) multiplexer-amplifier die and package. The AD8170ARZ is the RoHS-compliant tube/rail version, while AD8170AR-REEL is the tape-and-reel packaging variant. The "Z" suffix denotes RoHS compliance; the "-REEL" suffix denotes tape-and-reel shipment. Electrical performance is identical.
Are AD8170ARZ and AD8170AR-REEL electrically and functionally identical?
Yes. Both are the AD8170, a 2:1 multiplexer with an integrated high-speed current-feedback amplifier in an 8-lead SOIC package. They share the same datasheet specifications, pinout, and operating supply range of ±5 V to ±15 V (or single-supply operation). The only difference is packaging and RoHS status.
Is AD8170AR-REEL RoHS compliant?
No. The AD8170AR-REEL uses the non-RoHS "AR" grade designation without the "Z" suffix, indicating it is not lead-free/RoHS compliant. AD8170ARZ is the RoHS-compliant equivalent. Designers requiring RoHS compliance should specify AD8170ARZ or its tape-and-reel RoHS counterpart.
Can AD8170ARZ be used as a drop-in replacement for AD8170AR-REEL?
Yes, from an electrical and footprint standpoint they are interchangeable because both use the same 8-lead SOIC (R-8) package and identical pinout. The substitution is only constrained by RoHS compliance requirements and packaging format (tube vs. tape-and-reel) for automated assembly.
What is the supply voltage range for the AD8170?
The AD8170 operates from ±5 V to ±15 V dual supplies, and also supports single-supply operation. Designers should verify the exact recommended operating conditions in the official Analog Devices AD8170 datasheet before finalizing the supply rail design.
What package do AD8170ARZ and AD8170AR-REEL use?
Both devices are supplied in the 8-lead SOIC package, designated "R-8" in the Analog Devices ordering code. The package is surface-mount and suitable for automated pick-and-place assembly, with AD8170AR-REEL provided on tape-and-reel for high-volume production.
Which version should be selected for automated high-volume assembly?
AD8170AR-REEL is supplied in tape-and-reel format, which is preferred for automated pick-and-place lines. However, if RoHS compliance is required, the RoHS-compliant tape-and-reel ordering variant should be selected instead, since AD8170AR-REEL is the non-RoHS reel option.
Do AD8170ARZ and AD8170AR-REEL share the same datasheet specifications?
Yes. Both ordering codes refer to the same AD8170 silicon and package, so all datasheet parameters—such as bandwidth, slew rate, gain flatness, and supply current—apply equally. Only the ordering suffix (RoHS status and packaging) differs between the two part numbers.
