Replacement verdict
Compatible functional replacement candidate
The AD633ARZ-R7 and AD633ARZ are functionally equivalent four-quadrant analog multipliers from the same manufacturer, sharing identical core specifications, package, and pinout. The only meaningful distinction is the delivery format, with the -R7 suffix denoting tape-and-reel packaging versus the standard tube packaging of the AD633ARZ. Either part can serve as a direct functional substitute for the other in the same design, provided the assembly process accommodates the respective packaging format.

Key electrical and mechanical differences between the two devices
| Parameter | AD633ARZ-R7 | AD633ARZ | Why it matters |
|---|---|---|---|
| Function | Analog multiplier (four-quadrant) | Analog multiplier (four-quadrant) | Both parts perform the same core multiplication function, so they are functionally interchangeable in the circuit design. |
| Package / Case | 8-Lead SOIC (R-8) | 8-Lead SOIC (R-8) | Identical package ensures the same PCB footprint and assembly process can be used for either part. |
| Supply Voltage (dual) | ±8 V to ±18 V | ±8 V to ±18 V | Matching supply ranges confirm both parts operate under the same power conditions in the target design. |
| Total Error (multiplier) | ±1.0% of full scale (typical) | ±1.0% of full scale (typical) | Equivalent accuracy specifications mean the same signal-processing precision is achieved with either part. |
| Bandwidth (multiplier) | 1 MHz (typical) | 1 MHz (typical) | Same bandwidth supports identical high-frequency performance for modulation and multiplication applications. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Identical temperature ratings ensure both parts meet the same environmental requirements. |
| Packaging / Ordering Format | Tape and reel (R7 suffix), 750 units per reel | Tube / bulk (no reel suffix) | The R7 suffix denotes tape-and-reel packaging for automated pick-and-place assembly, while the base part is supplied in tubes; this affects manufacturing handling but not electrical performance. |
| Mounting Type | Surface mount | Surface mount | Both are surface-mount devices, so the same assembly technology applies. |

Frequently asked questions
What is the difference between AD633ARZ-R7 and AD633ARZ?
Both parts are the same AD633 analog multiplier IC in an 8-lead SOIC package (R-8 suffix). The only difference is packaging format: AD633ARZ is supplied in standard tube/rail packaging, while AD633ARZ-R7 is supplied on a 7-inch tape-and-reel for automated assembly. Electrical specifications and die are identical.
Are AD633ARZ-R7 and AD633ARZ electrically and functionally interchangeable?
Yes. Both share the same AD633 datasheet specifications, including the 8-lead SOIC (R-8) package, the same pinout, and the same multiplier/divider function. The -R7 suffix denotes reel packaging only, so they are interchangeable in circuit design.
What is the function of the AD633?
The AD633 is a four-quadrant analog multiplier that provides a scaled output W = (X1 − X2)(Y1 − Y2)/10 + Z. It can also be configured for squaring, division, square rooting, and modulation/demodulation functions using external components.
What package and pin configuration do AD633ARZ-R7 and AD633ARZ use?
Both are offered in the 8-lead SOIC package (R-8). The pinout includes X1, X2, Y1, Y2, Z, W, and supply pins VS+ and VS−, consistent with the AD633 datasheet.
What are the supply voltage requirements for the AD633?
The AD633 operates from dual supplies, typically ±15 V, with a specified operating range of ±8 V to ±18 V per the manufacturer datasheet. Both AD633ARZ-R7 and AD633ARZ share these supply requirements.
What is the operating temperature range for AD633ARZ-R7 and AD633ARZ?
The AD633ARZ grade is specified for the industrial temperature range of −40 °C to +85 °C, per the AD633 datasheet. Both the tube and reel versions share this rating.
Why would a designer choose AD633ARZ-R7 over AD633ARZ?
AD633ARZ-R7 is supplied on 7-inch tape-and-reel, which suits high-volume automated pick-and-place assembly lines. AD633ARZ in tubes is typically preferred for prototyping, low-volume runs, or manual assembly.
Do AD633ARZ-R7 and AD633ARZ differ in accuracy or performance grade?
No. Both carry the same "A" grade designation in the AD633 datasheet, indicating identical accuracy and performance specifications. The -R7 suffix refers only to tape-and-reel packaging and does not denote a different grade.
