Replacement verdict
Compatible functional replacement candidate
The AD633ARZ and AD633JRZ-RL are functionally equivalent analog multiplier ICs sharing the same core architecture, package, and pinout, making them viable substitutes in most designs. The primary distinction lies in their specified operating temperature ranges and corresponding grade classifications, so the AD633JRZ-RL should be validated against the target application's thermal profile before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD633ARZ | AD633JRZ-RL | Why it matters |
|---|---|---|---|
| Temperature Grade / Operating Range | Industrial (-40°C to +85°C) | Commercial (0°C to +70°C) | The industrial grade supports wider ambient temperatures, so it can be used in harsher environments where the commercial grade may not be specified. |
| Package / Mounting | 8-Lead SOIC (tube) | 8-Lead SOIC (tape and reel) | Both use the same SOIC footprint, but the packing differs; tape-and-reel suits automated high-volume assembly while tubes suit low-volume or prototyping. |
| Function | Four-quadrant analog multiplier | Four-quadrant analog multiplier | Identical core function confirms the parts are functionally interchangeable for multiplication, squaring, and division circuits. |
| Supply Voltage Range | ±8 V to ±18 V (dual supply) | ±8 V to ±18 V (dual supply) | Matching supply ranges mean the same power rails can be used without redesign. |
| Total Error (Multiplier) | ±1.0% of full scale (typical) | ±1.0% of full scale (typical) | Equivalent accuracy ensures comparable computational performance in signal-processing applications. |
| Bandwidth | 1 MHz (typical, small signal) | 1 MHz (typical, small signal) | Same bandwidth supports the same frequency range of operation for modulation and multiplication tasks. |
| Slew Rate | 20 V/µs (typical) | 20 V/µs (typical) | Identical slew rate preserves dynamic response and large-signal behavior. |
| Input Offset Voltage | ±5 mV (typical) | ±5 mV (typical) | Matching offset keeps DC accuracy consistent between the two parts. |
| Supply Current | 4 mA (typical) | 4 mA (typical) | Equal quiescent current means no change in power budget when substituting. |

Frequently asked questions
What are the key differences between the AD633ARZ and AD633JRZ-RL?
Both are AD633 four-quadrant analog multipliers from Analog Devices in an 8-lead SOIC package. The primary difference is the specified operating temperature range and grade: the AD633ARZ is specified over the industrial temperature range of −40°C to +85°C, while the AD633JRZ-RL is specified over the commercial temperature range of 0°C to +70°C. The AD633JRZ-RL is also supplied in tape-and-reel packaging, whereas the AD633ARZ is typically supplied in tube packaging.
Are the AD633ARZ and AD633JRZ-RL functionally interchangeable in a design?
Functionally, both devices implement the same multiplier transfer function (W = (X1 − X2)(Y1 − Y2)/10 V + Z) and share the same pinout and 8-lead SOIC footprint. However, substitution must account for the narrower 0°C to +70°C temperature rating of the AD633JRZ-RL versus the −40°C to +85°C rating of the AD633ARZ. A direct swap is only appropriate if the application's operating temperature remains within the commercial range and the packaging format is acceptable.
Do the AD633ARZ and AD633JRZ-RL have the same package and pinout?
Yes. Both parts are offered in the same 8-lead SOIC (R-8) package with an identical pin configuration, including the X1, X2, Y1, Y2, Z, W, and supply pins. This common footprint allows PCB layout reuse, but electrical and temperature-grade differences should still be verified before interchange.
What is the difference in packaging between the AD633ARZ and AD633JRZ-RL?
The AD633ARZ is typically supplied in tube packaging for through-hole or low-volume assembly handling, while the AD633JRZ-RL suffix indicates tape-and-reel packaging intended for automated surface-mount assembly. The "RL" designation on the AD633JRZ-RL refers to reel packaging. Buyers should confirm the exact packaging quantity and format from the distributor or manufacturer datasheet before ordering.
Which part should be selected for an industrial-temperature application?
For applications that must operate down to −40°C or up to +85°C, the AD633ARZ is the appropriate choice because it is specified over the industrial temperature range. The AD633JRZ-RL is specified only from 0°C to +70°C and should not be used outside that range without additional validation, as operation beyond the rated temperature is not guaranteed by the manufacturer.
Are the electrical specifications of the AD633ARZ and AD633JRZ-RL identical?
Both devices are AD633 multipliers sharing the same core architecture and typical performance characteristics, such as the 10 V nominal scale factor and four-quadrant operation. However, because they are different temperature grades, the guaranteed specifications are stated at their respective rated temperature ranges. Designers should consult the Analog Devices AD633 datasheet for the exact guaranteed limits applicable to each grade rather than assuming identical worst-case specifications.
Can the AD633JRZ-RL be used as a drop-in replacement for the AD633ARZ in existing assemblies?
A drop-in replacement is only valid if the assembly's operating temperature stays within 0°C to +70°C and the tape-and-reel packaging is compatible with the production process. Because the AD633JRZ-RL has a narrower temperature rating than the AD633ARZ, replacing an industrial-grade part with the commercial-grade part in an application exposed to temperatures below 0°C or above +70°C is not supported by the manufacturer's specifications.
Where can verified technical data for the AD633ARZ and AD633JRZ-RL be obtained?
Verified parameters, including temperature grades, package details, and packaging formats, are available from the Analog Devices official AD633 datasheet and from authorized distributors such as DigiKey, Mouser, and TTI. Designers should confirm grade, packaging suffix, and temperature range against these sources before finalizing a bill of materials.
