Replacement verdict
Compatible functional replacement candidate
The AD620ARZ and AD620AR-REEL are functionally equivalent implementations of the same instrumentation amplifier die, differing only in packaging format and ordering quantity. Both share identical electrical specifications, package outline, and temperature range, making them interchangeable in design and production. The primary distinction is the delivery form: the AD620ARZ is supplied in tube format while the AD620AR-REEL is supplied on tape and reel for automated assembly. Selection between the two should be driven by manufacturing handling requirements rather than electrical performance.

Frequently asked questions
What is the difference between AD620ARZ and AD620AR-REEL?
Both are the same AD620 instrumentation amplifier die in an 8-lead SOIC package with identical electrical specifications. The difference is packaging format: AD620ARZ is supplied in tube/tray quantities, while AD620AR-REEL is supplied on tape-and-reel for automated assembly. The AD620AR-REEL is the reel-packaged variant of the AD620AR grade.
Are AD620ARZ and AD620AR-REEL electrically identical?
Yes. Both use the AD620AR grade specification: gain set by a single external resistor (G = 1 to 10,000), 0.15% maximum gain error at G = 10, 10 ppm/°C gain drift, 50 µV maximum input offset voltage, 0.6 µV/°C offset drift, 1.0 nA maximum input bias current, 100 dB minimum CMRR at G = 10, and 18 nV/√Hz input voltage noise at 1 kHz. Package and die are the same; only the shipping format differs.
Can AD620ARZ and AD620AR-REEL be used interchangeably in a design?
Yes, from an electrical and footprint standpoint they are interchangeable because both are the same AD620AR-grade device in an 8-lead SOIC (R-8) package. The choice depends on assembly method: AD620AR-REEL is intended for pick-and-place reel-fed production, while AD620ARZ is typically used for tube-fed or low-volume/prototype assembly.
What package do AD620ARZ and AD620AR-REEL use?
Both are offered in the 8-lead SOIC package (Analog Devices R-8 suffix), with the same pinout: pin 1 and pin 8 for the gain resistor, pins 2 and 3 for inverting and non-inverting inputs, pin 4 for negative supply, pin 5 for output, pin 6 for reference, and pin 7 for positive supply.
What supply voltage range do AD620ARZ and AD620AR-REEL support?
Both operate from dual supplies of ±2.3 V to ±18 V, corresponding to a total supply span of 4.6 V to 36 V. They are specified for operation over the −40 °C to +85 °C temperature range.
How is gain set on the AD620ARZ and AD620AR-REEL?
Gain is programmed with a single external resistor RG connected between pins 1 and 8, using the relationship G = 49.4 kΩ / RG + 1. With RG open, the device operates at G = 1. This applies equally to both the AD620ARZ and AD620AR-REEL.
Which variant should be selected for high-volume automated PCB assembly?
AD620AR-REEL is the appropriate choice for high-volume automated assembly because it is supplied on tape-and-reel, which is compatible with standard pick-and-place feeders. AD620ARZ, supplied in tubes, is generally preferred for prototyping, low-volume runs, or manual assembly.
Do AD620ARZ and AD620AR-REEL carry the same moisture sensitivity and handling requirements?
Both are the same 8-lead SOIC body and are classified under the same moisture sensitivity level for that package family per the manufacturer's datasheet. Reel packaging does not change the MSL classification of the device itself; both should be handled according to the MSL and reflow profile stated in the Analog Devices datasheet and packaging information.
