Replacement verdict
Compatible functional replacement candidate
The ADR02WARZ-REEL is a functionally compatible candidate for the ADR02BRZ, sharing the same 5.0 V output, series voltage reference topology, and SOIC-8 footprint. The primary distinction is the grade-level initial accuracy and temperature coefficient, where the ADR02BRZ offers tighter B-grade tolerances while the ADR02WARZ-REEL provides A-grade specifications. Designers should validate that the wider initial accuracy and drift window of the ADR02WARZ-REEL satisfies the target application's error budget before substituting in precision-critical circuits.

Key electrical and mechanical differences between the two devices
| Parameter | ADR02BRZ | ADR02WARZ-REEL | Why it matters |
|---|---|---|---|
| Initial Accuracy | ±0.06% (max) | ±0.13% (max) | Tighter initial tolerance directly affects output voltage precision at power-up, which is critical for high-accuracy ADC/DAC references. |
| Temperature Coefficient | 3 ppm/°C (max) | 10 ppm/°C (max) | Lower tempco reduces voltage drift over temperature, essential for precision instrumentation and industrial measurement accuracy. |
| Output Voltage | 5.0 V | 5.0 V | Both provide the same nominal 5 V reference, so the output voltage is functionally interchangeable in most designs. |
| Package / Mounting | 8-SOIC (surface mount) | 8-SOIC (surface mount, tape and reel) | Identical package footprint allows drop-in board replacement; the reel variant only affects assembly packaging, not function. |
| Supply Voltage Range | 7 V to 36 V | 7 V to 36 V | Same input supply window ensures both parts operate under identical system power conditions. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Matching temperature ratings confirm both parts suit the same industrial and automotive-grade environments. |
| Output Current Capability | 10 mA (source/sink) | 10 mA (source/sink) | Equal drive capability means both can supply the same reference load without functional difference. |
| Grade / Accuracy Class | B grade (high precision) | A grade (standard precision) | The B grade offers tighter specs than the A grade, so substituting one for the other changes achievable system accuracy. |

Frequently asked questions
What are the key differences between the ADR02BRZ and ADR02WARZ-REEL?
Both devices are 5.0 V precision voltage references in the ADR02 family, but they differ in grade and packaging. The ADR02BRZ is a B-grade device in an 8-lead SOIC tube package, offering tighter initial accuracy and lower temperature coefficient, while the ADR02WARZ-REEL is an A-grade device in the same 8-lead SOIC supplied on tape and reel for automated assembly. The W suffix denotes the A-grade temperature coefficient and the REEL suffix denotes tape-and-reel packaging.
What initial output voltage accuracy does each grade specify?
The ADR02B grade provides an initial accuracy of ±0.06% maximum, while the ADR02A grade (used in the ADR02WARZ-REEL) provides ±0.1% maximum. Both are specified at 5.000 V nominal output.
How do the temperature coefficient specifications compare?
The ADR02B grade is specified with a temperature coefficient of 3 ppm/°C maximum, whereas the ADR02A grade is specified at 5 ppm/°C maximum over the operating temperature range. This makes the B grade preferable for applications requiring tighter drift performance.
Are the ADR02BRZ and ADR02WARZ-REEL pin-compatible?
Yes. Both devices are offered in the same 8-lead SOIC package with identical pin functions, so they are pin-compatible and share the same PCB land pattern. The difference is the accuracy grade and the delivery format (tube vs. tape and reel).
What is the difference between the Z and REEL suffixes?
The Z suffix indicates RoHS-compliant, lead-free (Pb-free) construction in an 8-lead SOIC package. The REEL suffix indicates the devices are supplied on tape and reel for high-volume automated pick-and-place assembly. The ADR02BRZ is supplied in tubes, while the ADR02WARZ-REEL is supplied on tape and reel.
Can the ADR02WARZ-REEL be used as a drop-in replacement for the ADR02BRZ?
Because both are pin-compatible 5.0 V references in the same 8-lead SOIC package, the ADR02WARZ-REEL can be used in place of the ADR02BRZ where the looser A-grade accuracy (±0.1% initial, 5 ppm/°C) is acceptable. Designs requiring the tighter B-grade specifications should retain the ADR02BRZ.
What are the operating temperature ranges for these references?
Both the ADR02BRZ and ADR02WARZ-REEL are specified for the extended industrial temperature range of −40°C to +125°C, making them suitable for industrial and automotive-adjacent applications.
Which grade should be selected for a high-volume production line?
For high-volume automated assembly, the ADR02WARZ-REEL is preferable because it is supplied on tape and reel, which supports pick-and-place equipment. If the design requires the tighter B-grade accuracy and drift performance, the ADR02BRZ should be selected, with tube packaging handled accordingly.
