X9317WM8T1 is listed in the Digital Potentiometers range at ChipApex. The manufacturer field lists Renesas Electronics Corporation. Its product description is IC DGTL POT 10KOHM 100TAP 8MSOP. Review the specifications below when checking this part for your BOM.
The Renesas X9317WM8T1 is a single-channel digital potentiometer featuring 100 taps and a resistance value of 10 kOhms. It utilizes a non-volatile memory architecture to retain wiper settings upon power loss. The device operates with a 5V supply voltage and employs an Up/Down (U/D, INC, CS) serial interface for control. Housed in an MSOP-8 surface-mount package, it exhibits a linear taper and a typical temperature coefficient of ±300ppm/°C. The component supports a contact resistance of 200 Ohms and functions within an industrial temperature range of -40°C to +85°C.
Verify the specific suffix 'M8' against official Renesas documentation to confirm the MSOP-8 package and industrial temperature grade. Confirm RoHS compliance status as legacy variants may differ. Check current production status, as older suffixes may indicate end-of-life or replacement by updated series members.
Select this component when a 10kOhm resistance value and 100-step resolution are required. Ensure the design accommodates the 5V logic levels for the serial interface. Verify that the MSOP-8 footprint matches the PCB layout constraints. Consider the ±20% tolerance if precise absolute resistance is critical.
This part belongs to the XDCP™ family of digitally controlled potentiometers from Renesas. It shares core architectural features with other X9317 variants but differs in resistance value, package type, and temperature rating compared to standard commercial versions.
Direct substitutes include X9317WM8IZ for leaded/compliance updates. For pin-compatible alternatives, evaluate CAT5113ZI series from onsemi.
