MCP2003A-E/MD LINbus Transceiver Half Equivalent & Substitute Parts

Part Overview

The MCP2003A-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. Alternative equivalent parts are necessary when addressing inventory constraints, lead time requirements, or design flexibility across compatible LINbus transceiver architectures.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCP2003A-E/MD is determined by strict equivalence across the following critical parameters:

• Protocol: LINbus half-duplex communication standard
• Number of Drivers/Receivers: 1/1 configuration
• Duplex Mode: Half-duplex operation
• Receiver Hysteresis: 175 mV threshold specification
• Voltage - Supply: 6V ~ 27V operating range
• Operating Temperature: -40°C ~ 125°C range
• Package / Case: 8-VDFN Exposed Pad form factor
• Supplier Device Package: 8-DFN (4x4) footprint
• Mounting Type: Surface Mount technology
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The MCP2003A-E/MD has two parametric equivalents: MCP2003-E/MD and MCP2004A-E/MD. Both parts maintain identical electrical specifications, thermal ratings, packaging dimensions, and compliance certifications. The primary distinction lies in the base product number designation (MCP2003 versus MCP2004), which reflects internal architectural variations within the Microchip LINbus transceiver family while preserving full functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—MCP2003A-E/MD, MCP2003-E/MD, and MCP2004A-E/MD—maintain active product status with Microchip Technology, ensuring continued manufacturing support and supply chain stability. Each part carries ROHS3 compliance and REACH Unaffected certification, meeting current environmental and regulatory requirements for industrial and automotive LINbus applications.

Selection between these equivalents should be based on inventory availability and lead time considerations. The MCP2004A-E/MD currently maintains the highest inventory level at 2193 pieces, followed by MCP2003-E/MD at 1335 pieces, and MCP2003A-E/MD at 1082 pieces. All parts are supplied in tube packaging and are new original stock.

Frequently Asked Questions (FAQ)

Q: Can MCP2003-E/MD and MCP2004A-E/MD be used interchangeably with MCP2003A-E/MD?

A: Yes. All three parts share identical electrical specifications, thermal operating ranges, package dimensions, and compliance certifications. The base product number variation (MCP2003 versus MCP2004) does not affect functional compatibility in LINbus half-duplex transceiver applications.

Q: Are there any package or footprint differences between these parts?

A: No. All three parts use the 8-VDFN Exposed Pad package with 8-DFN (4x4) footprint specifications. PCB layout and component placement remain identical across all three part numbers.

Q: What determines whether a part qualifies as a substitute for the MCP2003A-E/MD?

A: Substitution eligibility requires strict equivalence in protocol (LINbus), driver/receiver configuration (1/1), duplex mode (half), receiver hysteresis (175 mV), supply voltage range (6V ~ 27V), operating temperature range (-40°C ~ 125°C), package type (8-VDFN Exposed Pad), and compliance certifications (ROHS3, REACH Unaffected).

Q: Are all substitute parts manufactured by Microchip Technology?

A: Yes. MCP2003-E/MD and MCP2004A-E/MD are both manufactured by Microchip Technology, ensuring consistent quality standards and technical support.

Q: What is the moisture sensitivity level for these parts?

A: All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions during storage or handling.
