Replacement verdict
Compatible functional replacement candidate
The AD627BRZ and AD627BR-REEL are functionally equivalent implementations of the same AD627 instrumentation amplifier, differing only in packaging format and shipment configuration. Both parts share identical electrical specifications, die, and grade, making them interchangeable for design and qualification purposes; the choice between them is driven solely by assembly and procurement requirements rather than by any performance or functional distinction.

Key electrical and mechanical differences between the two devices
| Parameter | AD627BRZ | AD627BR-REEL | Why it matters |
|---|---|---|---|
| Amplifier Type | Instrumentation Amplifier | Instrumentation Amplifier | Confirms both parts are the same functional device type, ensuring substitutability in the target circuit. |
| Number of Channels | 1 | 1 | Channel count must match for the parts to be interchangeable in single-channel signal conditioning designs. |
| Supply Voltage Range | 2.2 V to 36 V (single), ±1.1 V to ±18 V (dual) | 2.2 V to 36 V (single), ±1.1 V to ±18 V (dual) | The supply range determines compatibility with the system power rails; identical ranges allow drop-in replacement. |
| Gain Range | 1 to 1000 (set by external resistor) | 1 to 1000 (set by external resistor) | Matching gain capability ensures the same signal scaling can be achieved without redesigning the gain network. |
| Input Offset Voltage (max) | ±150 µV | ±150 µV | Offset voltage directly affects DC accuracy; identical limits preserve measurement precision after substitution. |
| Gain Bandwidth Product | 80 kHz (G = 1) | 80 kHz (G = 1) | Bandwidth determines the maximum signal frequency the amplifier can handle; matching values ensure equivalent dynamic performance. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | The temperature range must cover the application environment; identical ratings confirm equal environmental robustness. |
| Package / Mounting Type | 8-Lead SOIC (Surface Mount) | 8-Lead SOIC (Surface Mount) | Package and mounting must match for physical PCB compatibility; identical packages allow direct board replacement. |
| Packaging / Delivery Form | Tube | Tape & Reel | Delivery form affects manufacturing handling and assembly line compatibility; tube vs. reel matters for automated pick-and-place production. |

Frequently asked questions
What is the difference between AD627BRZ and AD627BR-REEL?
Both parts are the same AD627BR-grade micropower instrumentation amplifier in an 8-lead SOIC package. The difference is packaging format: AD627BRZ is supplied in tube/tray quantities, while AD627BR-REEL is supplied on tape-and-reel for automated assembly. Electrical specifications are identical.
Are AD627BRZ and AD627BR-REEL electrically interchangeable?
Yes. Both are the same AD627BR die in the same 8-lead SOIC (R-8) package with identical pinout and specified performance, so they are electrically and functionally interchangeable. The only difference is the shipping container.
What are the key specifications of the AD627BR grade?
The AD627 is a micropower instrumentation amplifier with a supply range of 2.2 V to 36 V (single supply) or ±1.1 V to ±18 V (dual supply), a quiescent current of 60 µA typical, and a gain set by a single external resistor (G = 5 + 200 kΩ/RG). The B grade offers 25 µV maximum input offset voltage and 0.1% maximum gain error.
Which package do AD627BRZ and AD627BR-REEL use?
Both are offered in the 8-lead SOIC package (R-8 suffix), with an operating temperature range of −40°C to +85°C.
When should I choose AD627BR-REEL instead of AD627BRZ?
Choose AD627BR-REEL when using automated pick-and-place assembly lines that require tape-and-reel packaging. Choose AD627BRZ for prototyping, low-volume builds, or manual assembly where tube/tray packaging is sufficient.
Do both parts share the same datasheet and qualification data?
Yes. Both variants are covered by the same Analog Devices AD627 datasheet and the same qualification and reliability data for the AD627BR grade in the 8-lead SOIC package; only the packaging quantity and format differ.
What is the gain configuration for both variants?
Both use the same single-resistor gain setting: G = 5 + 200 kΩ/RG, with gains from 5 to 1000 achievable using an external resistor RG connected between the RG pins. The gain equation and resistor values are identical for AD627BRZ and AD627BR-REEL.
