Replacement verdict
Compatible functional replacement candidate
The AD5252BRUZ1 and AD5252BRU10 are functionally compatible digital potentiometers from the same AD5252 family, sharing identical architecture, interface, and package. The primary distinction is the end-to-end resistance value, which directly affects circuit behavior and must be validated against the target application requirements before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD5252BRUZ1 | AD5252BRU10 | Why it matters |
|---|---|---|---|
| End-to-End Resistance | 1 kΩ | 10 kΩ | Determines the nominal resistance range of the digital potentiometer, directly affecting the current and voltage levels in the target circuit. |
| Number of Positions | 256 | 256 | Defines the resolution of the potentiometer; identical resolution means both parts offer the same wiper adjustment granularity. |
| Number of Channels | 2 | 2 | Indicates how many independent potentiometer channels are available, which must match the circuit's channel count requirement. |
| Interface Type | I²C | I²C | Determines the digital communication protocol used to control the device; both parts use the same bus, ensuring host compatibility. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Specifies the allowable power supply window; matching ranges allow the same power rail to be used for either part. |
| Operating Temperature Range | -40 °C to +105 °C | -40 °C to +105 °C | Defines the environmental conditions under which the device operates reliably; identical ranges ensure equivalent thermal robustness. |
| Package / Mounting Type | 14-TSSOP, Surface Mount | 14-TSSOP, Surface Mount | Ensures physical and footprint compatibility on the PCB, allowing drop-in replacement without layout changes. |
| Nonvolatile Memory | Yes (EEPROM) | Yes (EEPROM) | Indicates whether the wiper setting is retained after power loss; both parts preserve settings, ensuring consistent power-up behavior. |

Frequently asked questions
What are the key differences between the AD5252BRUZ1 and AD5252BRU10?
The AD5252BRUZ1 and AD5252BRU10 are both dual-channel, 256-position digital potentiometers from Analog Devices. The primary difference is the end-to-end resistance: the AD5252BRUZ1 has a 1 kΩ nominal resistance, while the AD5252BRU10 has a 10 kΩ nominal resistance. Both are offered in a 14-lead TSSOP package and share the same I²C interface, nonvolatile memory, and general specifications.
Are the AD5252BRUZ1 and AD5252BRU10 pin-compatible?
Yes. Both devices are specified in the same 14-lead TSSOP (RU-14) package and share an identical pinout. This allows them to be used interchangeably on the same PCB footprint, provided the resistance value is appropriate for the application.
Can the AD5252BRUZ1 and AD5252BRU10 be used as direct substitutes for each other?
They are not direct substitutes in all cases because the end-to-end resistance differs by a factor of ten (1 kΩ vs. 10 kΩ). Circuit performance, such as wiper resistance effects, power dissipation, and the resulting RC time constants or voltage divider ratios, will differ. A substitution should only be made after verifying that the new resistance value meets the design requirements.
What is the resolution and number of positions for these digital potentiometers?
Both the AD5252BRUZ1 and AD5252BRU10 are 256-position devices, providing 8-bit resolution. The wiper can be set to any of 256 discrete steps between the A and B terminals.
Do the AD5252BRUZ1 and AD5252BRU10 have nonvolatile memory?
Yes. Both devices include nonvolatile EEPROM memory that stores the wiper setting. This allows the wiper position to be retained across power cycles without requiring reprogramming by the host controller.
What is the interface type for the AD5252BRUZ1 and AD5252BRU10?
Both devices use a 2-wire I²C-compatible serial interface. They support standard and fast I²C modes, allowing communication with most microcontrollers and digital signal processors.
What are the operating voltage and temperature ranges for these devices?
The AD5252 series operates from a single 2.7 V to 5.5 V supply. The specified operating temperature range for both the AD5252BRUZ1 and AD5252BRU10 is −40°C to +105°C, making them suitable for industrial and automotive applications.
How does the wiper resistance compare between the 1 kΩ and 10 kΩ versions?
Wiper resistance is a fixed parasitic resistance in series with the wiper terminal and is typically around 50 Ω to 100 Ω for both devices. However, its relative impact is much greater in the 1 kΩ version (AD5252BRUZ1) than in the 10 kΩ version (AD5252BRU10), which can affect the linearity and available adjustment range in low-resistance applications.
