Replacement verdict
Compatible functional replacement candidate
The AD5262BRUZ20-RL7 and AD5263BRU50 are both quad-channel digital potentiometers from Analog Devices, but they differ in end-to-end resistance, package type, and interface configuration. The AD5263BRU50 offers a higher resistance value and a different control interface, making it a potential functional substitute only after careful validation of the target circuit's resistance and interface requirements.

Key electrical and mechanical differences between the two devices
| Parameter | AD5262BRUZ20-RL7 | AD5263BRU50 | Why it matters |
|---|---|---|---|
| Number of Channels | 2 | 4 | Determines how many independent potentiometer channels are available in the package, directly affecting circuit density and channel count requirements. |
| End-to-End Resistance | 20 kΩ | 50 kΩ | Sets the nominal resistance range of the digital potentiometer, which must match the impedance requirements of the surrounding signal chain. |
| Resolution | 8-bit (256 positions) | 8-bit (256 positions) | Defines the number of wiper tap positions and thus the adjustment granularity for calibration or gain-setting applications. |
| Package / Case | 16-TSSOP | 16-TSSOP | Affects PCB footprint, thermal characteristics, and assembly compatibility; matching packages simplify drop-in replacement. |
| Interface Type | SPI | SPI | Determines the digital communication protocol required by the host controller to program the device. |
| Supply Voltage Range | 4.5 V to 16.5 V (single) / ±2.25 V to ±8.25 V (dual) | 4.5 V to 16.5 V (single) / ±2.25 V to ±8.25 V (dual) | Defines the allowable power supply rails and compatibility with the system's voltage domain. |

Frequently asked questions
What are the key differences between the AD5262BRUZ20-RL7 and the AD5263BRU50?
The AD5262BRUZ20-RL7 is a dual-channel, 20 kΩ digital potentiometer, while the AD5263BRU50 is a quad-channel, 50 kΩ digital potentiometer. The AD5262 offers two independently programmable resistor channels in a 16-lead TSSOP package, whereas the AD5263 provides four channels in a 24-lead TSSOP package. Both are single-supply or dual-supply digital potentiometers with SPI-compatible interfaces, but they differ in channel count, end-to-end resistance, and package size.
Are the AD5262BRUZ20-RL7 and AD5263BRU50 pin-compatible or footprint-compatible?
No. The AD5262BRUZ20-RL7 is supplied in a 16-lead TSSOP, and the AD5263BRU50 is supplied in a 24-lead TSSOP. They have different pin counts, pin assignments, and PCB land patterns, so they are not drop-in replacements for each other.
What is the end-to-end resistance of each device?
The AD5262BRUZ20-RL7 has a 20 kΩ nominal end-to-end resistance. The AD5263BRU50 has a 50 kΩ nominal end-to-end resistance. These values are specified in the respective manufacturer datasheets and determine the wiper resistance range and power dissipation characteristics in a given circuit.
How many programmable resistor channels does each part provide?
The AD5262BRUZ20-RL7 provides two independent digitally controlled resistor channels. The AD5263BRU50 provides four independent digitally controlled resistor channels. This difference directly affects the number of signal paths or calibration points that can be controlled by a single IC.
Do both devices use the same digital interface protocol?
Yes. Both the AD5262 and AD5263 families use an SPI-compatible serial interface for programming the wiper positions. However, the command structure and register map may differ because the AD5263 has four channels and the AD5262 has two. Always consult the specific datasheet for the exact serial interface timing and register definitions.
Can the AD5262BRUZ20-RL7 and AD5263BRU50 operate from the same supply voltage range?
Both devices are specified for single-supply operation from +4.5 V to +16.5 V or dual-supply operation from ±2.25 V to ±8.25 V, according to their respective datasheets. However, actual performance limits, such as wiper resistance and bandwidth, may vary between the 20 kΩ and 50 kΩ versions. Verify the exact supply conditions in the manufacturer datasheet for each part before designing.
Which device is more suitable for applications requiring more than two independent adjustable resistances?
The AD5263BRU50 is more suitable because it integrates four independent digital potentiometer channels in one package. The AD5262BRUZ20-RL7 only provides two channels, so applications needing three or four independently controlled resistances would require additional AD5262 devices or a different part such as the AD5263.
Are the AD5262BRUZ20-RL7 and AD5263BRU50 available in the same temperature grade or package type?
Both are offered in TSSOP packages and are specified over the industrial temperature range of −40°C to +85°C, based on their datasheets. However, the AD5262BRUZ20-RL7 uses a 16-lead TSSOP, while the AD5263BRU50 uses a 24-lead TSSOP. The package type is the same, but the lead count and body size differ.
