Replacement verdict
Compatible functional replacement candidate
The AD5262BRUZ20-RL7 and AD5262BRU200 are functionally compatible digital potentiometers from the same AD5262 family, sharing identical dual-channel architecture, I2C interface, package type, and operating temperature range. The primary distinction is the end-to-end resistance value, which directly affects the application's signal scaling and must be validated against the target circuit requirements before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD5262BRUZ20-RL7 | AD5262BRU200 | Why it matters |
|---|---|---|---|
| End-to-End Resistance | 20 kΩ | 200 kΩ | Determines the nominal resistance range of the digital potentiometer and directly affects signal attenuation, current loading, and matching to the surrounding circuit impedance. |
| Number of Positions | 256 | 256 | Defines the wiper resolution; identical resolution means both parts offer the same number of programmable tap settings. |
| Number of Channels | 2 | 2 | Indicates how many independent potentiometer channels are integrated, which affects board space and channel count in multi-channel designs. |
| Interface Type | SPI | SPI | Determines the digital communication protocol required by the host controller for programming the wiper position. |
| Supply Voltage Range | 4.5 V to 16.5 V (single supply); ±2.25 V to ±8.25 V (dual supply) | 4.5 V to 16.5 V (single supply); ±2.25 V to ±8.25 V (dual supply) | Defines the allowable operating voltage rails; matching ranges ensure the parts are interchangeable from a power-supply standpoint. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Specifies the environmental conditions under which the device is guaranteed to operate within datasheet limits. |
| Package / Mounting Type | 16-Lead TSSOP, Surface Mount | 16-Lead TSSOP, Surface Mount | Confirms physical footprint and assembly compatibility, which is essential for drop-in substitution on an existing PCB. |
| Packaging / Ordering Format | Tape and Reel (RL7) | Tube / Tray | Affects manufacturing handling and pick-and-place assembly; reel packaging is suited to automated production while tubes are often used for prototyping or low-volume runs. |

Frequently asked questions
What is the primary difference between the AD5262BRUZ20-RL7 and the AD5262BRU200?
The primary difference is the end-to-end resistance value. The AD5262BRUZ20-RL7 offers a 20 kΩ nominal resistance, while the AD5262BRU200 offers a 200 kΩ nominal resistance. Both are dual-channel, 256-position digital potentiometers from Analog Devices in a 16-lead TSSOP package.
Are the AD5262BRUZ20-RL7 and AD5262BRU200 pin-compatible?
Yes. Both devices are offered in the same 16-lead TSSOP (RU-16) package and share the same pinout, allowing them to be used interchangeably on a common PCB layout without redesign.
Can the AD5262BRUZ20-RL7 and AD5262BRU200 be used interchangeably in an existing design?
Not without verifying the circuit requirements. Although they are pin-compatible, the 10× difference in end-to-end resistance (20 kΩ vs. 200 kΩ) affects the wiper current, voltage divider ratios, and interaction with external components. The replacement must be validated against the specific application's resistance and loading requirements.
What is the resolution and number of positions for both the AD5262BRUZ20-RL7 and AD5262BRU200?
Both devices provide 256-position resolution per channel and are dual-channel (two independent potentiometers). They are controlled via an SPI-compatible serial interface.
What supply voltage range do the AD5262BRUZ20-RL7 and AD5262BRU200 support?
Both devices operate from a single supply of 4.5 V to 16.5 V, or from dual supplies of ±2.25 V to ±8.25 V, as specified in the Analog Devices AD5262 datasheet.
Do the AD5262BRUZ20-RL7 and AD5262BRU200 have the same temperature coefficient and tolerance?
Both devices share the same datasheet specifications for resistor tolerance and temperature coefficient, as they belong to the same AD5262 family. The resistance tolerance is typically ±30% for the end-to-end resistance, and the temperature coefficient is typically 35 ppm/°C in rheostat mode. These specifications apply equally to both resistance variants.
Which applications typically favor the AD5262BRUZ20-RL7 versus the AD5262BRU200?
The AD5262BRUZ20-RL7 (20 kΩ) is often selected for lower-impedance signal paths, such as programmable gain amplifier feedback networks or low-value trim circuits. The AD5262BRU200 (200 kΩ) is typically used in higher-impedance applications, such as sensor biasing or low-power divider networks, where lower current draw through the potentiometer is desired. Selection depends on the required wiper current and the impedance of the surrounding circuit.
Are the AD5262BRUZ20-RL7 and AD5262BRU200 RoHS compliant and available in the same packaging?
Yes. Both part numbers are RoHS-compliant and are supplied in the same 16-lead TSSOP package. The "Z" suffix in AD5262BRUZ20-RL7 indicates a RoHS-compliant version, and the AD5262BRU200 is also available in a RoHS-compliant TSSOP package. The "-RL7" suffix on the AD5262BRUZ20-RL7 denotes tape-and-reel packaging with a 750-piece reel quantity.
