MCP2004-E/MD LINbus Transceiver Equivalent & Substitute Parts

Part Overview

The MCP2004-E/MD is a half-duplex LINbus transceiver IC manufactured by Microchip Technology, designed for Local Interconnect Network (LIN) communication applications. This interface component operates across a wide supply voltage range of 6V to 27V and maintains active product status with full RoHS3 compliance. The device is packaged in an 8-pin DFN surface-mount configuration with exposed pad, suitable for automotive and industrial embedded systems requiring LIN protocol support.

Substitute parts are identified when equivalent electrical characteristics, mechanical compatibility, and regulatory compliance align with the original specification, enabling seamless integration in circuit designs without functional compromise.
