MCP4241T-103E/ST Equivalent & Substitute Parts Reference

Part Overview

The MCP4241T-103E/ST from Microchip Technology is a digital potentiometer IC in the Data Acquisition category. It provides 10k Ohm resistance with 129 taps across 2 circuits, accessible via an SPI interface in a 14-TSSOP surface-mount package. This device is active and offered in Tape & Reel (TR) packaging for automated assembly applications.
Alternative models are often required to ensure supply chain flexibility, maintain inventory continuity, and respond to packaging or procurement constraints.
