Replacement verdict
Compatible functional replacement candidate
The AD5260BRUZ50 and AD5260BRU200 are functionally compatible digital potentiometers from the same AD5260 family, sharing identical package, interface, and operating characteristics. The primary distinction is the end-to-end resistance value, which directly affects the application's resistance range and must be validated against the target circuit requirements before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD5260BRUZ50 | AD5260BRU200 | Why it matters |
|---|---|---|---|
| End-to-End Resistance | 50 kΩ | 200 kΩ | Determines the nominal resistance range of the digital potentiometer and directly affects the current through and voltage across the wiper circuit in the target application. |
| Number of Positions | 256 | 256 | Defines the resolution of the potentiometer; identical resolution means both parts offer the same number of tap settings for adjustment. |
| Number of Taps | 256 | 256 | Confirms the wiper can be set to the same number of discrete positions, ensuring equivalent adjustment granularity. |
| Interface Type | SPI | SPI | Both devices use the same serial control interface, so they are drop-in compatible from a digital communication standpoint. |
| Supply Voltage (Single) | 4.5 V to 16.5 V | 4.5 V to 16.5 V | Identical operating supply range means either part can be used in the same power rail design without modification. |
| Supply Voltage (Dual) | ±4.5 V to ±16.5 V | ±4.5 V to ±16.5 V | Same dual-supply capability allows both parts to handle bipolar signals in identical circuit configurations. |
| Package / Mounting | 14-TSSOP | 14-TSSOP | Identical package and footprint means no PCB layout change is required when substituting one part for the other. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Same temperature rating ensures both parts meet the same environmental and reliability requirements. |
| Wiper Resistance | ~60 Ω typical | ~60 Ω typical | Wiper resistance contributes to the total resistance seen in the signal path; similar values help preserve signal integrity and matching behavior. |
| Resistance Tolerance | ±30% | ±30% | Tolerance affects absolute accuracy of the set resistance; matching tolerance means both parts have comparable end-to-end accuracy. |

Frequently asked questions
What is the main difference between the AD5260BRUZ50 and AD5260BRU200?
The primary difference is the end-to-end resistance value of the digital potentiometer. The AD5260BRUZ50 has a nominal resistance of 50 kΩ, while the AD5260BRU200 has a nominal resistance of 200 kΩ. Both are single-channel, 256-position digital potentiometers from Analog Devices in a 14-lead TSSOP package.
Are the AD5260BRUZ50 and AD5260BRU200 pin-compatible?
Yes. Both devices are offered in the same 14-lead TSSOP (RU-14) package and share the same pinout. This allows them to be used interchangeably on a PCB without layout changes, provided the resistance value is suitable for the application.
Can the AD5260BRUZ50 and AD5260BRU200 be used as drop-in replacements for each other?
They are package and pin compatible, but they are not electrically identical because the end-to-end resistance differs by a factor of four. A direct substitution is only acceptable after verifying that the circuit performance, such as wiper resistance effects, loading, and signal range, remains within specification for the new resistance value.
What is the resolution and number of positions for both the AD5260BRUZ50 and AD5260BRU200?
Both devices provide 256 positions (8-bit resolution) with a nominal end-to-end resistance of 50 kΩ and 200 kΩ respectively. The wiper can be set to any of the 256 discrete steps via the SPI-compatible serial interface.
Do the AD5260BRUZ50 and AD5260BRU200 have the same digital interface and supply requirements?
Yes. Both parts use a 3-wire SPI-compatible serial interface and operate from a single 2.7 V to 5.5 V supply, or from dual ±2.5 V supplies. The digital input logic thresholds and timing specifications are identical for both resistance options.
How does the wiper resistance compare between the AD5260BRUZ50 and AD5260BRU200?
The wiper resistance is typically 60 Ω for both devices. However, because the AD5260BRUZ50 has a lower end-to-end resistance (50 kΩ), the wiper resistance represents a larger percentage of the total resistance, which can affect linearity and temperature coefficient in some applications compared to the 200 kΩ version.
Which applications are better suited for the AD5260BRUZ50 versus the AD5260BRU200?
The AD5260BRUZ50 (50 kΩ) is often preferred for lower impedance signal paths, such as audio volume control or sensor trimming where lower thermal noise and faster settling are beneficial. The AD5260BRU200 (200 kΩ) is better for higher impedance circuits, such as low-power bias adjustments or applications where minimal loading of the source is required.
Are the AD5260BRUZ50 and AD5260BRU200 RoHS compliant and lead-free?
Yes. Both the AD5260BRUZ50 and AD5260BRU200 are RoHS-compliant and lead-free, as indicated by the "Z" suffix in the part number. They are specified for the industrial temperature range of −40°C to +85°C.
