The non-volatile memory stores the wiper position at power-off, so the calibration value is present on the next power-up — no host reload required after a brownout or reset cycle. This makes it a fit for bias trimming, offset nulling, or volume control in systems where the microcontroller is not always running. ## SPI control and 129-tap resolution The SPI interface writes the wiper register directly — no up/down counter, no pulse-train timing to manage. With 129 taps, the step size on a 10 kΩ part is roughly 78 Ω per tap, giving finer granularity than a 64-tap device for the same resistance range. The wiper resistance is 75 Ω typical, which adds a fixed series offset at the wiper terminal; account for this when the wiper drives a low-impedance load directly. ## Through-hole DIP-8 for prototyping and low-volume production The 8-pin PDIP package is a through-hole footprint that fits standard 0.300-inch-wide sockets. For a bench prototype or a low-volume board that avoids SMT assembly, this package is straightforward to hand-solder and rework. The tolerance is ±20%, which is typical for semiconductor pots — the end-to-end resistance can vary from 8 kΩ to 12 kΩ, but the ratiometric divider accuracy (tap-to-end) is much tighter because it depends on the internal resistor matching, not the absolute value. ## Sourcing posture The active lifecycle means there is no supply discontinuity risk from an imminent EOL, and the standard PDIP package has broad second-source compatibility for socket-fit alternatives.","metaTitle":"Microchip MCP4141-103E/P Digital Pot, 10kΩ, 129 Taps, DIP-8","metaDescription":"Active-production MCP4141-103E/P digital potentiometer from Microchip. 10kΩ linear taper, 129 taps, SPI, non-volatile wiper memory. -40°C to +125°C.

The key difference is memory type: the MCP41010 uses volatile memory (wiper position resets to mid-scale on power-up), while the MCP4141 uses non-volatile WiperLock™ memory that retains the last wiper setting. The MCP41010 also offers 256 taps vs the MCP4141's 129 taps.
