Replacement verdict
Compatible functional replacement candidate
The AD5206BRZ50 and AD5204BR100 share the same quad-channel digital potentiometer architecture, 256-position resolution, SPI-compatible serial interface, and 24-lead SOIC package, making them functionally interchangeable in many designs. However, the AD5206BRZ50 provides 50 kΩ end-to-end resistance with six channels, while the AD5204BR100 offers 100 kΩ with four channels, so circuit designers must verify channel count and resistance tolerance requirements before substituting. The AD5204BR100 is a viable candidate where fewer channels and higher resistance are acceptable, but the AD5206BRZ50 remains the preferred choice for applications requiring six independent potentiometer channels.

Frequently asked questions
What are the main differences between the AD5206BRZ50 and AD5204BR100?
The AD5206BRZ50 is a 6-channel digital potentiometer with a 50 kΩ end-to-end resistance, while the AD5204BR100 is a 4-channel digital potentiometer with a 100 kΩ end-to-end resistance. Both are quad/hex-channel devices from Analog Devices, but they differ in channel count and nominal resistance value.
Are the AD5206BRZ50 and AD5204BR100 pin-compatible?
No. The AD5206BRZ50 is a 24-lead device (6 channels), and the AD5204BR100 is a 24-lead device (4 channels) in the same SOIC_W package, but the pin functions differ because the AD5206 provides six independent potentiometers while the AD5204 provides four. They are not direct drop-in replacements.
What is the resolution of the AD5206BRZ50 and AD5204BR100?
Both devices offer 8-bit resolution (256 positions) for each digital potentiometer channel, as specified in the Analog Devices AD5204/AD5206 datasheet.
What supply voltage range do the AD5206BRZ50 and AD5204BR100 support?
Both devices operate from a single supply of 2.7 V to 5.5 V, or from dual supplies of ±2.7 V to ±5.5 V, per the Analog Devices datasheet.
What is the interface type for the AD5206BRZ50 and AD5204BR100?
Both devices use a 3-wire SPI-compatible serial interface for programming the wiper positions, as documented in the Analog Devices AD5204/AD5206 datasheet.
Can the AD5206BRZ50 be used as a replacement for the AD5204BR100 in an existing design?
Not directly. The AD5206BRZ50 has six channels and 50 kΩ resistance, while the AD5204BR100 has four channels and 100 kΩ resistance. A replacement requires verifying channel count, resistance value, pinout, and software addressing against the target design and manufacturer datasheet.
What are the operating temperature ranges for the AD5206BRZ50 and AD5204BR100?
Both devices are specified for the industrial temperature range of −40°C to +85°C, as stated in the Analog Devices AD5204/AD5206 datasheet.
What package types are available for the AD5206BRZ50 and AD5204BR100?
Both the AD5206BRZ50 and AD5204BR100 are offered in a 24-lead SOIC_W (wide-body) package, per the Analog Devices ordering guide.
