MCP2544WFDT-H/SN Equivalent & Substitute Parts

Part Overview

The MCP2544WFDT-H/SN is a CANbus transceiver IC manufactured by Microchip Technology, designed for single-channel (1/1) communication applications. This Surface Mount device operates within the 4.5V to 5.5V supply voltage range and supports data rates up to 8Mbps across an operating temperature range of -40°C to 150°C. The component is currently in Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same functional category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MCP2544WFDT-H/SN is determined by strict equivalence across the following critical parameters:

• Protocol Compatibility: CANbus transceiver functionality
• Channel Configuration: 1/1 driver/receiver configuration
• Electrical Specifications: 8Mbps data rate, 200 mV receiver hysteresis, 4.5V to 5.5V supply voltage range
• Temperature Range: -40°C to 150°C operating temperature
• Package Compatibility: 8-SOIC form factor with 0.154" (3.90mm) width
• Compliance Standards: ROHS3 compliance, MSL Level 1

The MCP2562FDT-H/SN meets all these criteria and is classified as a parametric equivalent. Packaging format differences (Tape & Reel versus Cut Tape & Digi-Reel) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the MCP2544WFDT-H/SN and MCP2562FDT-H/SN are Active status components manufactured by Microchip Technology with identical electrical and mechanical specifications. Selection between these parts may be based on packaging format availability and supply chain considerations. Both components maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The MCP2562FDT-H/SN currently maintains higher inventory availability (4400 Pcs) compared to the MCP2544WFDT-H/SN (630 Pcs).

Frequently Asked Questions (FAQ)

Q: Can the MCP2562FDT-H/SN directly replace the MCP2544WFDT-H/SN in existing designs?

A: Yes. Both components share identical electrical specifications (8Mbps data rate, 200 mV receiver hysteresis, 4.5V to 5.5V supply voltage), identical package geometry (8-SOIC, 0.154" width), and identical operating temperature range (-40°C to 150°C). No circuit modifications are required.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging?

A: These are packaging and delivery formats only. Tape & Reel is supplied on continuous tape for automated assembly lines. Cut Tape & Digi-Reel is supplied in smaller quantities on cut tape segments. The electrical and mechanical properties of the components are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the MCP2544WFDT-H/SN and MCP2562FDT-H/SN are ROHS3 compliant and carry MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: What does MSL Level 1 mean?

A: MSL Level 1 indicates unlimited shelf life without moisture bake-out requirements. These components can be stored indefinitely under standard conditions without special handling.

Q: Are there any temperature or voltage derating considerations between these parts?

A: No. Both components operate identically across the full -40°C to 150°C temperature range and 4.5V to 5.5V supply voltage range.
