Replacement verdict
Compatible functional replacement candidate
AD620AR and AD620AR-REEL7 are the same AD620 instrumentation amplifier die in the same 8-lead SOIC package, differing only in packaging format: AD620AR is supplied in tubes, while AD620AR-REEL7 is supplied on a 7-inch tape-and-reel carrier. Electrical specifications, pinout, footprint, and temperature range are identical, so the two part numbers are functionally interchangeable; the only decision point is board-assembly packaging compatibility.

Frequently asked questions
What is the difference between AD620AR and AD620AR-REEL7?
Both parts are the same AD620 instrumentation amplifier die in the same 8-lead SOIC (R-8) package with identical electrical specifications. The difference is packaging format: AD620AR is supplied in standard tube/tray packaging, while AD620AR-REEL7 is supplied on a 7-inch tape-and-reel carrier for automated pick-and-place assembly.
Are AD620AR and AD620AR-REEL7 electrically and functionally identical?
Yes. Both are the AD620, a low-cost, low-power instrumentation amplifier with a gain set by a single external resistor (G = 1 to 10,000), 0.15% maximum gain error at G = 10, 50 µV maximum input offset voltage, 0.6 µV/°C maximum offset drift, 100 dB minimum CMRR at G = 10, and 1.3 mA maximum supply current. The reel suffix does not change device performance.
Can AD620AR-REEL7 be used as a drop-in replacement for AD620AR?
Yes, from an electrical and footprint standpoint the devices are interchangeable because both use the same 8-lead SOIC (R-8) body and pinout. The only practical consideration is assembly: AD620AR-REEL7 is optimized for reel-fed automated placement, while AD620AR is intended for tube-based handling.
What package and pinout do AD620AR and AD620AR-REEL7 use?
Both are offered in the 8-lead SOIC (R-8) package. The pinout is: 1 = RG, 2 = -IN, 3 = +IN, 4 = -VS, 5 = REF, 6 = OUTPUT, 7 = +VS, 8 = RG. Gain is programmed with a single resistor between pins 1 and 8.
What are the key supply and power specifications shared by both parts?
Both operate from dual supplies of ±2.3 V to ±18 V (or a single supply of 4.6 V to 36 V), with 1.3 mA maximum supply current and 0.8 mA typical. These ratings are identical for AD620AR and AD620AR-REEL7 because they are the same device.
Do AD620AR and AD620AR-REEL7 differ in temperature range or grade?
No. Both are the "A" grade specified over the -40°C to +85°C industrial temperature range. The "R" in the part number denotes the 8-lead SOIC package, and "REEL7" denotes 7-inch tape-and-reel packing; neither suffix indicates a different grade or temperature range.
Which part should be selected for high-volume automated PCB assembly?
AD620AR-REEL7 is the appropriate choice for high-volume automated assembly because it is supplied on 7-inch tape-and-reel compatible with standard pick-and-place equipment. AD620AR in tube packaging is typically used for prototyping, low-volume runs, or manual assembly.
Are AD620AR and AD620AR-REEL7 RoHS compliant?
RoHS compliance status must be confirmed against the specific manufacturer datasheet and ordering guide for the exact orderable part number, since compliance can vary by production lot and ordering code. Verify the current RoHS/lead-free designation for each part number with the manufacturer or an authorized distributor before finalizing a design or procurement decision.
