Replacement verdict
Compatible functional replacement candidate
The ADR02ARZ-REEL7 and ADR02ARZ are functionally equivalent voltage reference ICs from the same manufacturer, sharing identical electrical specifications, package, and temperature grade. The only distinction is the packaging format, with the REEL7 variant supplied on tape and reel for automated assembly. Both parts are interchangeable in design and application, making either suitable as a direct functional replacement for the other.

Key electrical and mechanical differences between the two devices
| Parameter | ADR02ARZ-REEL7 | ADR02ARZ | Why it matters |
|---|---|---|---|
| Reference Voltage | 5.0 V | 5.0 V | The nominal output voltage must match for the parts to be functionally interchangeable in a given circuit. |
| Initial Accuracy | ±0.1% (max) | ±0.1% (max) | Initial tolerance determines the reference's output error at room temperature and directly affects system accuracy. |
| Temperature Coefficient | 3 ppm/°C (max) | 3 ppm/°C (max) | Drift over temperature governs how stable the reference remains across the operating range. |
| Output Current Capability | 10 mA (source/sink) | 10 mA (source/sink) | The load-driving capability must be sufficient for the downstream circuitry in the application. |
| Supply Voltage Range | 7 V to 40 V | 7 V to 40 V | The input supply range must accommodate the system rail while providing adequate headroom above the 5 V output. |
| Operating Temperature Range | -40°C to +125°C | -40°C to +125°C | The temperature range must cover the application's environmental conditions for reliable operation. |
| Package | 8-Lead SOIC | 8-Lead SOIC | Package compatibility ensures the part fits the same PCB footprint and thermal profile. |
| Packaging / Delivery Form | Tape & Reel (7-inch, 1000 pcs) | Tube | The delivery form affects assembly line handling, pick-and-place compatibility, and minimum order quantities. |

Frequently asked questions
What is the difference between ADR02ARZ-REEL7 and ADR02ARZ?
Both parts are the same ADR02 voltage reference die in the same 8-lead SOIC package (R suffix) with the same A-grade tolerance. The only difference is packaging format: ADR02ARZ is supplied in tube/tray quantities, while ADR02ARZ-REEL7 is supplied on a 7-inch tape-and-reel for automated assembly. Electrical specifications are identical.
Are ADR02ARZ-REEL7 and ADR02ARZ electrically interchangeable?
Yes. Both are ADR02 A-grade devices with a 5.000 V output, initial accuracy of ±0.1% maximum, and a specified temperature coefficient of 10 ppm/°C maximum over the −40°C to +125°C range. Because the die and grade are the same, they are electrically interchangeable; only the delivery format differs.
What package do ADR02ARZ and ADR02ARZ-REEL7 use?
Both devices are offered in an 8-lead SOIC package, indicated by the "R" in the ordering code. The package is RoHS-compliant and the pinout is identical between the two orderable part numbers.
What is the difference between the REEL7 suffix and no suffix on ADR02ARZ?
The "REEL7" suffix denotes a 7-inch tape-and-reel packing format intended for pick-and-place production lines. The unsuffixed ADR02ARZ is the standard tube or tray shipment. The reel quantity per 7-inch reel should be confirmed against the current Analog Devices datasheet or distributor packaging specification before ordering.
Can ADR02ARZ-REEL7 be used as a drop-in replacement for ADR02ARZ in an existing design?
Yes, from an electrical and footprint standpoint, since both share the same die, grade, and 8-lead SOIC package. The only consideration is the assembly process: the reel format is intended for automated placement, so hand-assembly or prototyping workflows may prefer the tube version.
What are the key specifications shared by ADR02ARZ and ADR02ARZ-REEL7?
Both are 5.000 V precision voltage references with ±0.1% maximum initial accuracy, 10 ppm/°C maximum temperature coefficient, low output noise, and operation over the −40°C to +125°C industrial temperature range. They are pin-compatible 8-lead SOIC devices suitable for precision data acquisition and instrumentation designs.
Which part number should be selected for high-volume automated assembly?
ADR02ARZ-REEL7 is the appropriate choice for high-volume automated assembly because it is supplied on 7-inch tape-and-reel, which is compatible with standard pick-and-place equipment. ADR02ARZ in tube/tray form is better suited to low-volume, prototyping, or hand-assembly requirements.
