Replacement verdict
Compatible functional replacement candidate
The AD8602DRZ and AD8602AR-REEL are functionally interchangeable dual operational amplifiers from the same AD8602 family, sharing identical core electrical characteristics. The primary distinction lies in package and ordering format, so the AD8602DRZ can serve as a compatible functional replacement for the AD8602AR-REEL provided the board layout accommodates the SOIC-8 footprint and reel-to-tube handling differences are acceptable.

Frequently asked questions
What are the key differences between the AD8602DRZ and AD8602AR-REEL?
Both are dual, precision, low-noise operational amplifiers from Analog Devices based on the same AD8602 core. The primary differences are package type and ordering format: the AD8602DRZ is supplied in an 8-lead SOIC (R-8) tube/rail package, while the AD8602AR-REEL is supplied in an 8-lead SOIC (R-8) tape-and-reel format for automated assembly. Electrical performance is identical since both use the same die.
Are the AD8602DRZ and AD8602AR-REEL electrically interchangeable?
Yes. Both devices share the same AD8602 silicon die, so the electrical specifications—including supply voltage range (2.7 V to 5.5 V), input offset voltage, gain bandwidth (8 MHz typical), and low noise (8 nV/√Hz typical)—are identical. They differ only in packaging/ordering format, not in electrical behavior.
What package do the AD8602DRZ and AD8602AR-REEL use?
Both parts are offered in an 8-lead SOIC package (Analog Devices R-8 suffix). The "D" and "A" grade designations refer to the same SOIC body; the "Z" suffix indicates RoHS-compliant lead-free construction, and "REEL" indicates tape-and-reel shipment. Pinout and footprint are the same for both.
What is the difference between the "DRZ" and "AR-REEL" suffixes?
The "DRZ" suffix denotes an 8-lead SOIC package in RoHS-compliant (Z) form, typically shipped in tubes/rails. The "AR-REEL" suffix denotes the same 8-lead SOIC package supplied on tape-and-reel for high-volume pick-and-place assembly. The "A" and "D" grade codes both correspond to the standard AD8602 grade; consult the Analog Devices datasheet to confirm grade-specific specifications.
Can the AD8602AR-REEL be used as a drop-in replacement for the AD8602DRZ?
Yes, from an electrical and footprint standpoint they are drop-in compatible because both are the same AD8602 die in the same 8-lead SOIC package. The only practical consideration is the delivery format: the REEL version is intended for automated assembly, while the DRZ is typically supplied in tubes. Verify the specific grade and RoHS status against the manufacturer datasheet before substitution.
What are the key specifications of the AD8602?
The AD8602 is a dual, precision, low-noise CMOS operational amplifier with a supply range of 2.7 V to 5.5 V, typical gain bandwidth of 8 MHz, low input offset voltage, and low noise of approximately 8 nV/√Hz. It is rail-to-rail input and output and is suited for precision signal conditioning, sensor interfaces, and portable instrumentation. Confirm exact limits in the Analog Devices AD8602 datasheet.
Which part should be selected for high-volume automated PCB assembly?
The AD8602AR-REEL is the appropriate choice for high-volume automated assembly because it is supplied on tape-and-reel, which is compatible with pick-and-place equipment. The AD8602DRZ, typically supplied in tubes, is better suited to prototyping or low-volume runs. Both share identical electrical performance.
