Replacement verdict
Compatible functional replacement candidate
The AD5242BRZ10 and AD5242BR10 are functionally equivalent dual-channel digital potentiometers from Analog Devices, both offering 10 kΩ end-to-end resistance, 256-position resolution, and I²C-compatible interfaces. The primary distinction lies in the package and ordering format, with the BRZ10 suffix denoting RoHS-compliant lead-free construction. Designers should verify solder profile compatibility and inventory availability before substituting, but electrical performance and footprint remain interchangeable across both variants.

Frequently asked questions
What is the difference between the AD5242BRZ10 and the AD5242BR10?
The AD5242BRZ10 is the RoHS-compliant, lead-free version of the AD5242BR10. Both are dual-channel, 10 kΩ digital potentiometers from Analog Devices in a 16-lead SOIC package. The "Z" suffix in AD5242BRZ10 indicates Pb-free/RoHS compliance, while the AD5242BR10 is the non-RoHS version containing lead in the terminal finish. Functionally and electrically, they are identical.
Are the AD5242BRZ10 and AD5242BR10 pin-compatible?
Yes. Both devices use the same 16-lead SOIC (R-16) package with identical pinouts. The only difference is the terminal finish and RoHS compliance status, so they are pin-to-pin compatible in PCB layout.
Can the AD5242BRZ10 directly replace the AD5242BR10 in an existing design?
Yes, from a functional and pinout perspective, the AD5242BRZ10 can directly replace the AD5242BR10. However, if the design is required to be non-RoHS or if the assembly process is qualified only for leaded finishes, the substitution should be validated against the applicable manufacturing and regulatory requirements.
What is the resistance value and resolution of the AD5242BRZ10 and AD5242BR10?
Both the AD5242BRZ10 and AD5242BR10 are 10 kΩ digital potentiometers with 256-position resolution. They provide dual-channel (two independent potentiometers) operation with an I²C-compatible serial interface.
What supply voltage range do the AD5242BRZ10 and AD5242BR10 support?
Both devices operate from a single 2.7 V to 5.5 V supply, or from dual supplies of ±2.7 V. This makes them suitable for a wide range of low-voltage and portable applications.
What is the operating temperature range for the AD5242BRZ10 and AD5242BR10?
Both the AD5242BRZ10 and AD5242BR10 are specified for the industrial temperature range of −40°C to +85°C.
Do the AD5242BRZ10 and AD5242BR10 have the same digital interface?
Yes. Both devices use a 2-wire I²C-compatible serial interface supporting standard and fast modes (up to 400 kHz). The interface timing, addressing, and register map are identical between the two versions.
Which version should be selected for a new RoHS-compliant design?
For new designs requiring RoHS compliance, the AD5242BRZ10 should be selected. The AD5242BR10 is the non-RoHS version and is generally not recommended for new designs where lead-free manufacturing and environmental compliance are required.
