Replacement verdict
Compatible functional replacement candidate
The AD627ARZ and AD627AR-REEL are functionally equivalent implementations of the same AD627 instrumentation amplifier, differing only in packaging format. The AD627ARZ is supplied in an anti-static tube for through-hole or low-volume assembly, while the AD627AR-REEL is delivered on tape-and-reel for automated pick-and-place production. Both share identical electrical specifications, die, and SOIC-8 footprint, making them interchangeable for design purposes; selection should be driven by assembly method and inventory handling requirements rather than electrical performance.

Frequently asked questions
What is the difference between AD627ARZ and AD627AR-REEL?
Both parts are the same AD627 instrumentation amplifier die in an 8-lead SOIC package. The difference is packaging format: AD627ARZ is supplied in tube/tray quantities, while AD627AR-REEL is supplied on tape-and-reel for automated assembly. Electrical specifications are identical.
Are AD627ARZ and AD627AR-REEL electrically interchangeable?
Yes. Both are the AD627 in the same 8-lead SOIC (R-8) package with identical pinout and specified performance, so they are electrically and functionally interchangeable. The choice depends on the assembly method (manual/tube vs. automated reel feed).
What are the key specifications of the AD627?
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 approximately 60 µA maximum, a gain set by a single external resistor (G = 5 + 200 kΩ/RG), and a gain range of 5 to 1000. It is specified for the −40 °C to +85 °C industrial temperature range.
What package do AD627ARZ and AD627AR-REEL use?
Both are offered in the 8-lead SOIC package (R-8 suffix), with an industry-standard SOIC footprint and pinout. The "Z" suffix in AD627ARZ denotes lead-free (RoHS-compliant) construction, consistent with the reel variant.
Can AD627ARZ and AD627AR-REEL be used in new designs?
Both are active, catalogued Analog Devices parts available through authorized distributors. Designers should confirm current lifecycle status and availability with the manufacturer or an authorized distributor before committing to volume production.
Which variant should be selected for automated SMT production?
AD627AR-REEL is the tape-and-reel option intended for automated pick-and-place assembly. AD627ARZ in tube/tray form is better suited to manual assembly, prototyping, or low-volume runs.
Do both variants share the same operating temperature range and supply requirements?
Yes. Since both are the same AD627AR die in the same package, they share the same specified operating temperature range (−40 °C to +85 °C) and the same supply voltage range (2.2 V to 36 V single supply, ±1.1 V to ±18 V dual supply).
