Replacement verdict
Compatible functional replacement candidate
The AD826ARZ-REEL7 and AD826AR are functionally equivalent dual operational amplifiers sharing identical core silicon, supply range, and package footprint; the REEL7 suffix denotes tape-and-reel packaging only, so the two part numbers are interchangeable in design with no electrical or mechanical revalidation required.

Key electrical and mechanical differences between the two devices
| Parameter | AD826ARZ-REEL7 | AD826AR | Why it matters |
|---|---|---|---|
| Amplifier Type | Voltage Feedback | Voltage Feedback | Both are voltage-feedback op amps, so the basic topology and compensation behavior are the same for substitution. |
| Number of Channels | 2 | 2 | Dual-channel configuration must match for pinout and circuit compatibility. |
| Gain Bandwidth Product | 50 MHz | 50 MHz | GBW determines the maximum usable frequency for a given closed-loop gain; identical values preserve AC performance. |
| Slew Rate | 350 V/µs | 350 V/µs | Slew rate limits large-signal bandwidth and distortion; matching values ensure equivalent transient response. |
| Input Offset Voltage (Max) | 2 mV | 2 mV | Offset voltage affects DC accuracy; identical limits mean comparable precision in signal chains. |
| Supply Voltage Range | ±2.5 V to ±15 V | ±2.5 V to ±15 V | The supply range must cover the application rails; matching ranges allow drop-in use in the same power design. |
| Input Bias Current | 3.3 µA | 3.3 µA | Bias current impacts DC error in high-impedance circuits; identical values preserve accuracy. |
| Package / Mounting | 8-SOIC, Surface Mount, Tape & Reel | 8-SOIC, Surface Mount, Tube | Same package and footprint allow physical interchange; only the packaging format (reel vs tube) differs for assembly handling. |
| Packaging Format | Tape & Reel (REEL7) | Tube | Packaging affects automated pick-and-place assembly and inventory handling, though the electrical part is the same. |
| RoHS Compliance | RoHS Compliant (Z suffix) | Non-RoHS (lead-containing) | RoHS status affects regulatory compliance and solder process compatibility; the Z-suffix part is lead-free while the non-Z part is not. |

Frequently asked questions
What is the difference between AD826ARZ-REEL7 and AD826AR?
Both are dual high-speed operational amplifiers from Analog Devices in an 8-lead SOIC package. The AD826AR is the standard tube/tray ordering option, while AD826ARZ-REEL7 is the RoHS-compliant (Z suffix) version supplied on a 7-inch tape-and-reel for automated assembly. The electrical specifications of the AD826 die are the same; the differences are packaging, RoHS status, and shipping format.
Are AD826ARZ-REEL7 and AD826AR electrically identical?
Yes. Both parts use the same AD826 amplifier core, with the same datasheet parameters such as 50 MHz unity-gain bandwidth, 350 V/µs slew rate, and 50 mA output current. The "Z" in AD826ARZ-REEL7 denotes RoHS compliance, not a different silicon revision.
Is AD826ARZ-REEL7 a drop-in replacement for AD826AR?
Yes, in terms of package and pinout. Both are 8-lead SOIC (R-8) devices with identical pin functions. The AD826ARZ-REEL7 is RoHS-compliant, so it can replace AD826AR in new designs, but the non-Z AD826AR may still be required where non-RoHS assembly processes are specified.
What does the "Z" suffix mean on AD826ARZ-REEL7?
The "Z" suffix indicates that the device is RoHS-compliant, meaning it is manufactured with lead-free termination finish and meets the RoHS directive. The AD826AR without the Z suffix is the non-RoHS version.
What does "REEL7" mean in AD826ARZ-REEL7?
"REEL7" indicates the device is supplied on a 7-inch tape-and-reel carrier, typically containing 750 units per reel for the 8-lead SOIC package. This format is intended for automated pick-and-place assembly. AD826AR is typically supplied in tubes.
Can AD826AR and AD826ARZ-REEL7 be mixed on the same PCB assembly?
Electrically and mechanically they are interchangeable in the same 8-lead SOIC footprint. However, mixing RoHS and non-RoHS parts on one assembly may conflict with the process and compliance requirements of the production line, so the choice should follow the assembly's RoHS policy.
Do AD826ARZ-REEL7 and AD826AR share the same operating temperature range?
Yes. Both are specified over the industrial temperature range of −40°C to +85°C, as stated in the AD826 datasheet. Packaging and RoHS status do not change the temperature rating.
