Replacement verdict
Compatible functional replacement candidate
The AD633ARZ and AD633ARZ-RL are functionally identical four-quadrant analog multipliers from Analog Devices, differing only in packaging format. The AD633ARZ is supplied in a tube, while the AD633ARZ-RL is the same die and grade delivered on tape and reel for automated assembly. Both share identical electrical specifications, pinout, and SOIC-8 footprint, making them interchangeable for design and procurement purposes; selection should be driven solely by the assembly method and inventory packaging preference.

Key electrical and mechanical differences between the two devices
| Parameter | AD633ARZ | AD633ARZ-RL | 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 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. |
| Supply Voltage (Dual) | ±8 V to ±18 V | ±8 V to ±18 V | Same operating supply range means the parts can be dropped into the same power rail design. |
| Total Error (Multiplier) | ±1.0% of full scale (typical) | ±1.0% of full scale (typical) | Matching accuracy specifications confirm equivalent signal-processing performance. |
| Bandwidth (Multiplier) | 1 MHz (typical) | 1 MHz (typical) | Same bandwidth supports the same frequency range of operation in the target application. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Identical temperature ratings ensure the same environmental robustness. |
| Packaging / Delivery Form | Tube | Tape & Reel | The only difference is the shipping format; -RL denotes reel packaging suited to automated high-volume assembly, while the base part is supplied in tubes. |
| Mounting Type | Surface Mount | Surface Mount | Same mounting style confirms compatibility with the same assembly technology. |

Frequently asked questions
What is the difference between AD633ARZ and AD633ARZ-RL?
Both parts are the same AD633 analog multiplier die in an 8-lead SOIC package (R-8 suffix). The "-RL" suffix denotes tape-and-reel packaging, while AD633ARZ is supplied in tube/tray format. Electrical specifications are identical; only the shipping packaging and order quantity differ.
Are AD633ARZ and AD633ARZ-RL electrically and functionally interchangeable?
Yes. Both are the same AD633JN/AR grade device (A grade, 8-lead SOIC) with identical pinout, transfer function W = (X1 − X2)(Y1 − Y2)/10 + Z, and specified performance over the 0°C to +70°C commercial temperature range. They differ only in packaging format.
What is the function of the AD633?
The AD633 is a four-quadrant analog multiplier that computes W = (X1 − X2)(Y1 − Y2)/10 + Z. It provides a 10 V full-scale output, ±1% typical total error, and a 1 MHz bandwidth, and is used for multiplication, division, squaring, modulation, and signal processing.
What package and pinout do AD633ARZ and AD633ARZ-RL use?
Both are offered in an 8-lead SOIC (R-8) package. The pinout is: 1 = X1, 2 = X2, 3 = Y1, 4 = Y2, 5 = Z, 6 = W, 7 = V−, 8 = V+. The same land pattern and footprint apply to both variants.
What supply voltage and temperature range do these parts support?
Both AD633ARZ and AD633ARZ-RL operate from dual supplies of ±8 V to ±18 V (typically ±15 V) and are specified over the commercial temperature range of 0°C to +70°C.
Why would a designer choose the -RL tape-and-reel version over the tube version?
The -RL variant is supplied on tape and reel, which is compatible with automated pick-and-place assembly lines and high-volume production. The tube version (AD633ARZ) is typically used for prototyping, low-volume runs, or manual assembly.
Do AD633ARZ and AD633ARZ-RL share the same datasheet and specifications?
Yes. Both variants are covered by the same Analog Devices AD633 datasheet. The "-RL" designation is a packaging/ordering code only and does not change any electrical, thermal, or mechanical specification of the device.
