Linear taper means the resistance between the wiper and terminal B changes by a constant step of about 390 Ohm per tap — no log scaling, so this part is suited for voltage dividers, programmable gain amplifiers, and calibration trims rather than audio volume control. Non-volatile memory stores the wiper position at power-off via internal EEPROM — the IC powers up at the last programmed tap, eliminating the need for a firmware re-initialization routine on every POR cycle. The I²C interface supports a selectable address pin, allowing up to four devices on the same bus without an external I²C mux. Supply range spans 1.8V to 5.5V, covering 1.8V MCU rails and 3.3V or 5V mixed-signal domains from a single supply. The -40°C to 125°C operating range qualifies the part for industrial and under-hood automotive environments — not just commercial temperature bins. ## Package and thermal — 10-DFN exposed pad, 3x3 mm Housed in a 10-VFDFN exposed-pad package, supplier device package 10-DFN (3x3 mm). Tape and reel packaging — 3,000 units per reel, standard for pick-and-place. Reflow profile per JEDEC J-STD-020 for MSL level 1 (no floor-life limit before reflow). ## Active lifecycle — no obsolescence risk Product status is Active — no NRND, no EOL notice, no last-time-buy deadline. Microchip continues to manufacture and support the MCP4662T-104E/MF through authorized distribution.

The MCP4662T-104E/MF offers two channels, 100 kOhm, 257 taps, non-volatile memory, and an I²C interface — it is a different pinout and package (10-DFN vs SOT-23-5), so it will not drop into a board designed for the MCP4014T-103E/OT without a PCB layout change."},{"question":"What is the wiper resistance and temperature coefficient?","answer":"Typical wiper resistance is 75 Ohm. Temperature coefficient is 150 ppm/°C, meaning the end-to-end resistance drifts about 15 Ohm per 100°C shift — the wiper voltage ratio tracks linearly regardless of absolute resistance tolerance."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/MCP4662T-104E-MF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/MCP4662T-104E-MF when reusing this data.
