Replacement verdict
Compatible functional replacement candidate
The AD829ARZ and AD829AR-REEL are functionally equivalent, sharing the same die, package, and specified performance characteristics; the only distinction is the delivery format, with the REEL variant supplied on tape and reel for automated assembly. Either part number can be used interchangeably in the same circuit design, and selection should be driven by production packaging requirements rather than electrical or functional differences.

Key electrical and mechanical differences between the two devices
| Parameter | AD829ARZ | AD829AR-REEL | Why it matters |
|---|---|---|---|
| Manufacturer | Analog Devices Inc. | Analog Devices Inc. | Same manufacturer ensures consistent design, process, and quality standards between the two parts. |
| Amplifier Type | Voltage Feedback Amplifier | Voltage Feedback Amplifier | The amplifier topology determines the external compensation and feedback network design, so matching types preserves circuit behavior. |
| Number of Circuits | 1 | 1 | Single-channel configuration must match for pin-compatible drop-in substitution. |
| Package / Case | 8-SOIC | 8-SOIC | Identical package footprint allows the parts to be used interchangeably on the same PCB layout. |
| Mounting Type | Surface Mount | Surface Mount | Same mounting style is required for physical compatibility in assembly. |
| Supply Voltage Range | ±4.5 V to ±18 V (dual) | ±4.5 V to ±18 V (dual) | Matching supply range ensures the part operates correctly in the target power rail design. |
| Gain Bandwidth Product | 120 MHz | 120 MHz | Bandwidth determines achievable signal frequency and closed-loop response; identical values preserve AC performance. |
| Slew Rate | 230 V/µs | 230 V/µs | Slew rate limits large-signal transient response; matching values keeps dynamic behavior consistent. |
| Input Offset Voltage | 0.5 mV (typ) | 0.5 mV (typ) | Offset voltage affects DC accuracy; identical typical values preserve precision in signal chains. |
| Packaging / Delivery Form | Tube | Tape & Reel | Delivery form differs for automated assembly versus manual handling, but the electrical part is the same. |

Frequently asked questions
What is the difference between AD829ARZ and AD829AR-REEL?
Both parts are the same AD829 operational amplifier die in an 8-lead SOIC package (R-8 suffix). The AD829ARZ is supplied in tube/tray packaging, while the AD829AR-REEL is supplied on tape-and-reel for automated assembly. The "Z" suffix on AD829ARZ denotes RoHS-compliant lead finish, whereas AD829AR-REEL reflects the reel packaging option of the same device family.
Are AD829ARZ and AD829AR-REEL electrically and functionally identical?
Yes. Both are the AD829, a low-noise, high-speed operational amplifier with a 120 MHz gain bandwidth product, 230 V/µs slew rate, and 1.7 nV/√Hz input voltage noise. The electrical specifications are the same; the only difference is the shipping packaging (tube vs. tape-and-reel).
What package do AD829ARZ and AD829AR-REEL use?
Both devices are offered in an 8-lead SOIC (Small Outline Integrated Circuit) package, identified by the "R" suffix in the part number. The package is RoHS-compliant for the AD829ARZ variant.
Can AD829ARZ and AD829AR-REEL be used interchangeably in a design?
Yes, from an electrical and footprint standpoint they are interchangeable because they share the same die and 8-lead SOIC package. The choice between them depends on the assembly method: AD829ARZ for hand or low-volume assembly, and AD829AR-REEL for automated pick-and-place production lines.
What are the key performance specifications of the AD829?
The AD829 is a low-noise, high-speed op amp with 120 MHz gain bandwidth, 230 V/µs slew rate, 1.7 nV/√Hz input voltage noise at 1 kHz, and 0.02% differential gain error. It operates from ±5 V to ±15 V supplies and is used in video, imaging, and instrumentation applications.
Why would a designer choose the AD829AR-REEL over the AD829ARZ?
The AD829AR-REEL is supplied on tape-and-reel, which is compatible with automated surface-mount assembly equipment. This packaging reduces handling and improves throughput for high-volume production, while the AD829ARZ tube packaging is better suited to prototyping and low-volume builds.
Do AD829ARZ and AD829AR-REEL differ in temperature range or grade?
No. Both are the "A" grade of the AD829 in the 8-lead SOIC package and share the same specified operating temperature range and performance grade. The suffix differences relate only to RoHS compliance (Z) and packaging format (REEL).
