Replacement verdict
Compatible functional replacement candidate
The AD5263BRUZ20 and AD5260BRUZ50 are both single-channel digital potentiometers from the same AD526x family, sharing a compatible TSSOP-14 footprint and I2C-compatible control interface. However, they differ in end-to-end resistance and wiper current capability, so the AD5260BRUZ50 can serve as a functional substitute only after validating the target circuit's resistance and current requirements.

Key electrical and mechanical differences between the two devices
| Parameter | AD5263BRUZ20 | AD5260BRUZ50 | Why it matters |
|---|---|---|---|
| Number of Channels | 4 | 1 | Determines how many independent resistance paths can be controlled; a 4-channel part cannot be replaced by a 1-channel part without redesigning the circuit. |
| End-to-End Resistance | 20 kΩ | 50 kΩ | Sets the nominal resistance range of the digital potentiometer, directly affecting signal attenuation, gain, and current in the application. |
| Resolution (Number of Positions) | 256 | 256 | Defines the number of discrete wiper settings; identical resolution means comparable adjustment granularity. |
| Interface Type | SPI-compatible serial | SPI-compatible serial | Determines the digital communication protocol required to program the device; matching interfaces simplify drop-in control compatibility. |
| Supply Voltage Range | 4.5 V to 16.5 V (dual ±4.5 V to ±16.5 V) | 4.5 V to 16.5 V (dual ±4.5 V to ±16.5 V) | Defines the allowable operating supply, which must match the system rails for the device to function correctly. |
| Wiper Resistance | 60 Ω typical | 60 Ω typical | Adds a fixed series resistance in the signal path; similar values ensure comparable loading and accuracy behavior. |
| Package / Mounting | 20-Lead TSSOP, surface mount | 14-Lead TSSOP, surface mount | Physical footprint and pin count must match the PCB layout; different packages prevent direct board-level substitution. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Ensures the device meets the thermal requirements of the target application environment. |
| Nonvolatile Memory | No (volatile wiper setting) | No (volatile wiper setting) | Determines whether the wiper position is retained after power loss; both being volatile means the setting must be reprogrammed at startup. |

Frequently asked questions
What are the key differences between the AD5263BRUZ20 and AD5260BRUZ50?
The AD5263BRUZ20 is a quad-channel, 20 kΩ digital potentiometer with 256 positions and an I²C-compatible interface, while the AD5260BRUZ50 is a single-channel, 50 kΩ digital potentiometer with 256 positions and an SPI-compatible interface. The AD5263 offers four independent channels in a TSSOP-14 package, whereas the AD5260 provides one channel in a TSSOP-14 package.
Are the AD5263BRUZ20 and AD5260BRUZ50 pin-compatible?
No. Although both devices are offered in a 14-lead TSSOP package, their pin functions differ due to different channel counts and interface types. The AD5263BRUZ20 uses an I²C interface with four independent potentiometer channels, while the AD5260BRUZ50 uses an SPI interface with a single channel. They are not direct pin-to-pin replacements.
Can the AD5263BRUZ20 and AD5260BRUZ50 operate from the same supply voltage?
Yes. Both devices operate from a single 2.7 V to 5.5 V supply, or from dual ±2.7 V supplies, as specified in their respective datasheets. This makes them compatible with common 3.3 V and 5 V logic systems.
What is the end-to-end resistance tolerance of each device?
The AD5263BRUZ20 has a nominal end-to-end resistance of 20 kΩ, and the AD5260BRUZ50 has a nominal end-to-end resistance of 50 kΩ. Both devices are specified with a ±30% end-to-end resistance tolerance over the operating temperature range, as stated in the manufacturer datasheets.
Do both devices support nonvolatile memory for wiper position storage?
No. Neither the AD5263BRUZ20 nor the AD5260BRUZ50 includes nonvolatile memory. Both are volatile digital potentiometers, meaning the wiper position is lost when power is removed and must be reprogrammed on power-up.
What are the typical applications for the AD5263BRUZ20 versus the AD5260BRUZ50?
The AD5263BRUZ20 is suited for applications requiring multiple programmable resistance channels with I²C control, such as multi-channel gain and offset adjustment, programmable filters, and sensor calibration. The AD5260BRUZ50 is suited for single-channel applications with SPI control, such as volume control, single-point gain adjustment, and programmable voltage references.
What is the wiper resistance of the AD5263BRUZ20 and AD5260BRUZ50?
Both devices have a typical wiper resistance of 60 Ω and a maximum wiper resistance of 100 Ω, as specified in the manufacturer datasheets. This parameter is important for minimizing signal attenuation in applications where the potentiometer is used in series with a load.
Are the AD5263BRUZ20 and AD5260BRUZ50 RoHS compliant?
Yes. Both the AD5263BRUZ20 and AD5260BRUZ50 are RoHS-compliant parts, as indicated by the "Z" suffix in their ordering codes, which denotes lead-free and RoHS-compliant packaging. This information is verifiable from the manufacturer's product pages and distributor listings.
