Replacement verdict
Compatible functional replacement candidate
The AD5162BRMZ10 and AD5161BRM5-RL7 are both single-channel 10 kΩ digital potentiometers from Analog Devices with compatible I²C interfaces and similar volatile memory architectures, making the AD5162BRMZ10 a viable functional replacement candidate for the AD5161BRM5-RL7 in many designs. However, the differing package footprints and wiper resistance characteristics require careful validation before committing to a drop-in substitution.

Frequently asked questions
What are the key differences between the AD5162BRMZ10 and AD5161BRM5-RL7 digital potentiometers?
The AD5162BRMZ10 is a dual-channel, 10 kΩ, 256-position digital potentiometer in a 10-lead MSOP package, while the AD5161BRM5-RL7 is a single-channel, 5 kΩ, 256-position digital potentiometer in a 10-lead MSOP package. The AD5162 offers two independent potentiometers, whereas the AD5161 provides one.
Are the AD5162BRMZ10 and AD5161BRM5-RL7 pin-compatible?
No. Although both are in 10-lead MSOP packages, their pin functions differ because the AD5162 is a dual potentiometer and the AD5161 is a single potentiometer. Pin assignments and internal terminal connections are not interchangeable.
What is the end-to-end resistance of each device?
The AD5162BRMZ10 has a 10 kΩ end-to-end resistance. The AD5161BRM5-RL7 has a 5 kΩ end-to-end resistance. These values are specified in the respective manufacturer datasheets.
How many positions do these digital potentiometers support?
Both the AD5162BRMZ10 and AD5161BRM5-RL7 provide 256 positions, which corresponds to 8-bit resolution for wiper adjustment.
What digital interface do the AD5162BRMZ10 and AD5161BRM5-RL7 use?
Both devices use a 3-wire SPI-compatible serial interface for programming the wiper position. This interface is documented in the Analog Devices datasheets for each part.
Can the AD5161BRM5-RL7 be used as a drop-in replacement for the AD5162BRMZ10?
No. The AD5161BRM5-RL7 is a single-channel 5 kΩ device, while the AD5162BRMZ10 is a dual-channel 10 kΩ device. They differ in channel count, resistance, and internal architecture, so a direct drop-in replacement is not possible without design changes.
What are the typical operating voltage ranges for these digital potentiometers?
Both the AD5162BRMZ10 and AD5161BRM5-RL7 operate from a single 2.7 V to 5.5 V supply, as specified in their respective Analog Devices datasheets.
What package type and pin count do these devices use?
Both the AD5162BRMZ10 and AD5161BRM5-RL7 are offered in a 10-lead MSOP (Mini Small Outline Package). The package code "RM" in the part numbers indicates MSOP.
