Replacement verdict
Compatible functional replacement candidate
The ADR02ARZ and ADR02AR-REEL7 are functionally equivalent voltage reference ICs sharing the same core die, electrical specifications, and package footprint; the only distinction is the delivery format, with the ADR02AR-REEL7 supplied on tape and reel for automated assembly. Either part can serve as a direct substitute for the other in the same design, provided the procurement format matches the production requirement.

Key electrical and mechanical differences between the two devices
| Parameter | ADR02ARZ | ADR02AR-REEL7 | Why it matters |
|---|---|---|---|
| Reference Type | Series Voltage Reference | Series Voltage Reference | Both are series-mode references, so the regulation topology and external component requirements are the same. |
| Output Voltage | 5.0 V | 5.0 V | The nominal reference voltage must match the target system's ADC/DAC full-scale requirement. |
| Initial Accuracy | ±0.1% (max) | ±0.1% (max) | Initial tolerance directly affects absolute system accuracy before calibration. |
| Temperature Coefficient | 3 ppm/°C (max) | 3 ppm/°C (max) | Drift over temperature determines accuracy stability in real operating environments. |
| Output Current Capability | 10 mA (source/sink) | 10 mA (source/sink) | Determines how much load the reference can drive while maintaining regulation. |
| Supply Voltage Range | 7 V to 36 V | 7 V to 36 V | Must be compatible with the available system rail and headroom above the 5 V output. |
| Operating Temperature Range | -40°C to +125°C | -40°C to +125°C | Confirms the part is rated for the intended industrial/automotive thermal environment. |
| Package / Mounting | 8-SOIC (surface mount) | 8-SOIC (surface mount) | Same footprint and mounting style allow direct PCB drop-in substitution. |
| Packaging / Ordering Format | Tube | Tape & Reel (7-inch reel) | Packaging differs for automated assembly vs. manual/prototype handling, but the die and electrical performance are identical. |

Frequently asked questions
What are the ADR02ARZ and ADR02AR-REEL7?
Both are ADR02 precision 5.0 V voltage references from Analog Devices. The ADR02ARZ is supplied in a tube/tray format, while the ADR02AR-REEL7 is the same device supplied on a 7-inch tape-and-reel for automated assembly.
Are the ADR02ARZ and ADR02AR-REEL7 electrically identical?
Yes. Both share the same ADR02 die and grade, offering a 5.000 V output with initial accuracy of ±0.1% (max) and a temperature coefficient of 3 ppm/°C (max) over the −40°C to +125°C range, per the Analog Devices ADR02 datasheet.
What package do these devices use?
Both are offered in an 8-lead SOIC package (SOIC_N, R-8 suffix). The ADR02ARZ and ADR02AR-REEL7 differ only in shipping/packaging format, not in package type or pinout.
What is the difference between the ADR02ARZ and ADR02AR-REEL7?
The only difference is the packaging format: ADR02ARZ is supplied in standard tube/tray packaging, while ADR02AR-REEL7 is supplied on a 7-inch tape-and-reel (typically 750 units per reel) intended for pick-and-place production lines.
Can the ADR02ARZ and ADR02AR-REEL7 be used interchangeably in a design?
Yes. Because they are the same die, grade, and package, they are electrically and mechanically interchangeable. The choice between them is driven by manufacturing handling (manual/tube vs. automated tape-and-reel), not by performance.
What are the key operating parameters of these references?
Per the Analog Devices ADR02 datasheet: 5.000 V output, ±0.1% initial accuracy (max), 3 ppm/°C temperature coefficient (max), low dropout operation, and a supply range of 7 V to 40 V, with a quiescent current of approximately 1 mA.
Which packaging option should be selected for production?
For automated SMT production lines, the ADR02AR-REEL7 tape-and-reel format is preferred for pick-and-place feeders. For prototyping, low-volume, or manual assembly, the ADR02ARZ tube/tray format is typically more convenient.
