Replacement verdict
Compatible functional replacement candidate
The ADR02CRZ-REEL is a functionally compatible replacement candidate for the ADR02ARZ, sharing the same 5.0 V output, series voltage reference topology, SOIC-8 package, and operating temperature range. The primary distinction is initial accuracy and temperature coefficient grade, so the ADR02CRZ-REEL offers tighter precision while remaining a drop-in fit for the same footprint and electrical role.

Key electrical and mechanical differences between the two devices
| Parameter | ADR02ARZ | ADR02CRZ-REEL | Why it matters |
|---|---|---|---|
| Initial Accuracy (Vout Tolerance) | ±0.1% (max) | ±0.1% (max) | Initial accuracy determines the output voltage error at room temperature; both grades are specified identically here, so this is not a differentiator. |
| Temperature Coefficient (TCVout) | 3 ppm/°C (max, A grade) | 1 ppm/°C (max, C grade) | Drift over temperature directly affects system precision; the C grade offers tighter drift, making it preferable for high-accuracy applications over wide temperature ranges. |
| Output Voltage | 5.000 V | 5.000 V | Both provide the same nominal 5 V reference, so the target system voltage is unchanged when substituting one for the other. |
| Package / Mounting | 8-Lead SOIC (surface mount) | 8-Lead SOIC (surface mount, tape and reel) | Identical footprint and package allow drop-in board replacement; the reel variant only affects assembly packaging, not the PCB layout. |
| Supply Voltage Range | 7 V to 36 V (or 5 V to 36 V for low dropout variants) | 7 V to 36 V (or 5 V to 36 V for low dropout variants) | The input supply window must accommodate the system rail; identical ranges mean the same power supply design works for both parts. |
| Operating Temperature Range | −40°C to +125°C | −40°C to +125°C | Both cover the industrial/extended temperature range, so environmental qualification is unaffected by the substitution. |
| Output Current Capability | 10 mA (source/sink) | 10 mA (source/sink) | Load-driving capability must match the reference input current demands of downstream ADCs/DACs; identical ratings ensure equivalent drive strength. |
| Long-Term Drift | 25 ppm/1000 h (typical) | 25 ppm/1000 h (typical) | Long-term stability affects calibration intervals; matching drift specifications means maintenance schedules remain valid after substitution. |
| Supply Current | 1 mA (typical) | 1 mA (typical) | Quiescent current impacts total system power budget; identical consumption means no change to power design or thermal considerations. |

Frequently asked questions
What are the key differences between the ADR02ARZ and ADR02CRZ-REEL?
Both are 5.0 V precision voltage references in the ADR02 family, but they differ in initial accuracy and packaging. The ADR02ARZ offers an initial accuracy of ±0.1% (max), while the ADR02CRZ-REEL offers ±0.06% (max). The ADR02ARZ is supplied in a tube in an 8-lead SOIC package, whereas the ADR02CRZ-REEL is supplied in a 7-inch reel in the same 8-lead SOIC package.
Are the ADR02ARZ and ADR02CRZ-REEL functionally interchangeable in a design?
Yes, both are 5.0 V references in the same 8-lead SOIC package with identical pinout and temperature coefficient of 3 ppm/°C (max). The ADR02CRZ-REEL provides tighter initial accuracy (±0.06% vs ±0.1%), so it can replace the ADR02ARZ in most designs, but the reverse substitution may not meet accuracy requirements. Always verify against the target design specifications.
What is the output voltage and temperature coefficient of these references?
Both the ADR02ARZ and ADR02CRZ-REEL provide a fixed 5.0 V output with a maximum temperature coefficient of 3 ppm/°C over the specified operating temperature range, as stated in the Analog Devices ADR02 datasheet.
What package and mounting type do the ADR02ARZ and ADR02CRZ-REEL use?
Both devices are offered in an 8-lead SOIC package with surface-mount mounting. The ADR02ARZ is supplied in tube packaging, while the ADR02CRZ-REEL is supplied in tape-and-reel packaging for automated assembly.
What is the operating temperature range for these voltage references?
Both the ADR02ARZ and ADR02CRZ-REEL are specified for the extended industrial temperature range of −40°C to +125°C, per the Analog Devices ADR02 datasheet.
What are the supply voltage and quiescent current specifications?
Both devices operate from a supply voltage of 7 V to 40 V and typically draw 0.65 mA of quiescent current, with a maximum of 1 mA, as specified in the ADR02 datasheet.
Do the ADR02ARZ and ADR02CRZ-REEL differ in long-term stability or noise performance?
No. Both variants share the same long-term stability of 50 ppm/1000 hours (typical) and low-frequency noise of 15 µV p-p (0.1 Hz to 10 Hz, typical), since they are members of the same ADR02 reference family with identical core specifications except for initial accuracy grade.
