Replacement verdict
Compatible functional replacement candidate
The AD826ARZ-REEL and AD826AR are functionally equivalent dual high-speed operational amplifiers sharing identical core die specifications, including dual channel count, ±5 V to ±15 V supply range, 50 MHz gain-bandwidth product, and 350 V/µs slew rate. The AD826ARZ-REEL is the RoHS-compliant, tape-and-reel packaged variant of the AD826AR, making it a direct functional replacement candidate for automated assembly environments, provided the reel packaging format and lead-free solder process compatibility are validated against the target board's manufacturing requirements.

Key electrical and mechanical differences between the two devices
| Parameter | AD826ARZ-REEL | AD826AR | Why it matters |
|---|---|---|---|
| Amplifier Type | Voltage Feedback | Voltage Feedback | Both are voltage-feedback op amps, so the fundamental topology and compensation behavior are the same. |
| Number of Channels | 2 | 2 | Dual-channel configuration determines board layout and pin count; identical here for direct substitution. |
| Gain Bandwidth Product | 50 MHz | 50 MHz | GBW sets the achievable closed-loop bandwidth; matching values preserve AC performance. |
| Slew Rate | 350 V/µs | 350 V/µs | Slew rate limits large-signal response; identical slew rate ensures equivalent transient behavior. |
| Input Offset Voltage (max) | 2 mV | 2 mV | Offset voltage affects DC accuracy; matching maximum offset maintains precision in DC-coupled designs. |
| Supply Voltage Range | ±2.5 V to ±15 V | ±2.5 V to ±15 V | Operating supply range determines compatibility with the system rails; identical range allows drop-in use. |
| Supply Current per Amplifier | 6.6 mA | 6.6 mA | Quiescent current impacts power budget and thermal design; equal values keep power consumption unchanged. |
| Package / Mounting | 8-SOIC, Surface Mount | 8-SOIC, Surface Mount | Package and mounting style must match for PCB footprint compatibility; both are 8-lead SOIC. |
| Packaging / Reel | Tape & Reel | Tube / Bulk | Packaging differs for automated assembly versus prototyping; the reel suffix indicates tape-and-reel supply. |
| Lead-Free / RoHS Status | RoHS Compliant, Lead-Free | Non-RoHS (leaded) | The "Z" suffix denotes lead-free/RoHS construction; this affects regulatory compliance and solder process requirements. |

Frequently asked questions
What is the difference between AD826ARZ-REEL and AD826AR?
Both are the same AD826 dual high-speed operational amplifier die in an 8-lead SOIC package. The AD826ARZ-REEL is supplied in tape-and-reel packaging (typically 2,500 units per reel) for automated assembly, while the AD826AR is the tube/rail-packaged version. The "Z" suffix in AD826ARZ-REEL denotes RoHS-compliant lead-free construction, whereas the AD826AR is the non-RoHS legacy ordering code.
Are AD826ARZ-REEL and AD826AR electrically and functionally interchangeable?
Yes. Both order codes refer to the same AD826 amplifier with identical electrical specifications (50 MHz unity-gain bandwidth, 350 V/µs slew rate, 50 mA output current, ±5 V to ±15 V supply range). The only differences are packaging format and RoHS compliance, so they are functionally interchangeable in the same PCB footprint.
Do AD826ARZ-REEL and AD826AR use the same package and pinout?
Yes. Both are offered in the 8-lead SOIC (R-8) package with the standard dual op-amp pinout: 1 = OUT A, 2 = -IN A, 3 = +IN A, 4 = V-, 5 = +IN B, 6 = -IN B, 7 = OUT B, 8 = V+. The PCB land pattern is identical for both order codes.
Is AD826ARZ-REEL RoHS compliant, and is AD826AR non-compliant?
AD826ARZ-REEL carries the "Z" suffix indicating RoHS-compliant, lead-free construction per the manufacturer's ordering guide. The AD826AR is the older non-RoHS ordering code. Designs requiring RoHS compliance should specify the AD826ARZ-REEL or the equivalent RoHS tube version (AD826ARZ).
Can AD826ARZ-REEL be used as a drop-in replacement for AD826AR in an existing design?
Yes, from an electrical and footprint standpoint the two are drop-in compatible because they share the same die, package, and pinout. The only consideration is that AD826ARZ-REEL is RoHS-compliant and supplied on tape-and-reel, so reflow profile and assembly handling should follow lead-free soldering requirements.
What are the key specifications shared by AD826ARZ-REEL and AD826AR?
Both share the AD826 datasheet specifications: 50 MHz unity-gain bandwidth, 350 V/µs slew rate, 50 mA minimum output current, 15 nV/√Hz input voltage noise, 0.07% differential gain and 0.03° differential phase error, operating on ±5 V to ±15 V dual supplies, in an 8-lead SOIC package over the -40°C to +85°C industrial temperature range.
Why would a design choose AD826ARZ-REEL over AD826AR?
AD826ARZ-REEL is preferred for high-volume automated SMT assembly because tape-and-reel packaging feeds pick-and-place equipment directly, and its RoHS-compliant construction satisfies current environmental and regulatory requirements. AD826AR (tube packaging, non-RoHS) is typically selected only for legacy designs or prototyping where RoHS is not required.
