Replacement verdict
Compatible functional replacement candidate
The AD627BRZ and AD627BR-REEL7 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 performance characteristics, making them interchangeable for design and qualification purposes. The primary distinction is the delivery form: the AD627BRZ is supplied in tube packaging, while the AD627BR-REEL7 is supplied on tape and reel for automated assembly. Selection between the two should be driven by manufacturing logistics rather than electrical or functional requirements.

Key electrical and mechanical differences between the two devices
| Parameter | AD627BRZ | AD627BR-REEL7 | Why it matters |
|---|---|---|---|
| Amplifier Type | Instrumentation Amplifier | Instrumentation Amplifier | Confirms both parts are the same functional amplifier type, so they are directly substitutable in the same circuit role. |
| Number of Channels | 1 | 1 | Both are single-channel devices, so channel count does not affect interchangeability. |
| Supply Voltage Range | 2.2 V to 36 V (single supply), ±1.1 V to ±18 V (dual supply) | 2.2 V to 36 V (single supply), ±1.1 V to ±18 V (dual supply) | Identical supply range means either part works in the same power rail configuration. |
| Gain Range | 1 to 1000 (set by external resistor) | 1 to 1000 (set by external resistor) | Same programmable gain range ensures the same signal scaling behavior in the application. |
| Input Offset Voltage (max) | ±125 µV | ±125 µV | Matching offset voltage means DC accuracy is unchanged when swapping parts. |
| Input Bias Current (max) | 27 nA | 27 nA | Identical bias current keeps errors in high-impedance sensor interfaces consistent. |
| Gain Bandwidth Product | 80 kHz | 80 kHz | Same bandwidth supports the same frequency response and stability in the circuit. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Identical temperature range ensures both parts meet the same environmental requirements. |
| Package / Mounting | 8-Lead SOIC (tube) | 8-Lead SOIC (tape and reel, 7-inch reel) | Same SOIC package and footprint, but different packaging format affects assembly handling and inventory, not electrical substitutability. |

Frequently asked questions
What is the difference between AD627BRZ and AD627BR-REEL7?
Both parts are the same AD627BR-grade instrumentation amplifier in an 8-lead SOIC package; the difference is packaging format. AD627BRZ is supplied in tube/tray packaging, while AD627BR-REEL7 is supplied on a 7-inch tape-and-reel for automated assembly. The electrical specifications are identical.
Are AD627BRZ and AD627BR-REEL7 electrically identical?
Yes. Both are the AD627BR grade with the same datasheet specifications, including gain range of 5 to 1000 set by a single external resistor, supply range of 2.2 V to 36 V (dual ±1.1 V to ±18 V), and the same 8-lead SOIC pinout. Only the shipping packaging differs.
Can AD627BR-REEL7 be used as a drop-in replacement for AD627BRZ?
Yes, from an electrical and footprint standpoint they are interchangeable because both use the same 8-lead SOIC (R-8) package and pinout. The only practical consideration is that AD627BR-REEL7 is provided on tape-and-reel, which suits automated pick-and-place lines, whereas AD627BRZ is supplied in tubes.
What package do AD627BRZ and AD627BR-REEL7 use?
Both devices are offered in the 8-lead SOIC package (R-8 suffix in the ordering code). The "Z" suffix in AD627BRZ indicates RoHS-compliant lead-free construction, consistent with the AD627BR-REEL7 ordering code.
What is the gain range and gain-setting method for these parts?
The AD627BRZ and AD627BR-REEL7 provide a gain range of 5 to 1000, set by a single external resistor connected between the RG pins. This single-resistor gain programming is a key feature of the AD627 instrumentation amplifier family.
What supply voltage range do AD627BRZ and AD627BR-REEL7 support?
Both parts operate from a single supply of 2.2 V to 36 V, or from dual supplies of ±1.1 V to ±18 V, making them suitable for low-voltage and battery-powered instrumentation applications.
Which packaging option should be selected for production versus prototyping?
AD627BR-REEL7 (7-inch tape-and-reel) is typically selected for automated SMT production lines, while AD627BRZ (tube/tray) is often used for prototyping, low-volume builds, or manual assembly. Both contain the same AD627BR-grade die and package.
