Key Parameters

Substitute Part Grouping Explanation

Substitution of the USB5734/MRD01 is based on the following critical parameters:

Package Compatibility: The substitute part must utilize the same 64-VFQFN Exposed Pad package format with 9x9 millimeter dimensions to ensure mechanical and thermal compatibility with existing PCB layouts and assembly processes.

Manufacturer Continuity: Microchip Technology remains the authorized manufacturer for equivalent parts, ensuring consistent design support, documentation, and supply chain reliability.

Functional Category: The substitute must operate within the Interface category to maintain electrical and protocol compatibility with system architecture.

Product Status: The substitute part must carry an Active product status to guarantee ongoing availability, technical support, and manufacturing continuity.

The USB5734/MRD02 meets all substitution criteria through identical package specifications, same manufacturer origin, and active production status.

Parameter Comparison

Engineering Selection Recommendations

The USB5734/MRD02 is the manufacturer-recommended substitute for the obsolete USB5734/MRD01. Selection of the active part is justified by the following factors:

Product Status Alignment: The USB5734/MRD02 carries Active product status, ensuring manufacturer support, continued availability, and compliance with current supply chain requirements. The obsolete status of the original part creates risk for future procurement and technical support.

Package Specification Compliance: Both parts share identical 64-VFQFN Exposed Pad package specifications with 9x9 millimeter dimensions, enabling direct PCB layout compatibility without redesign.

Manufacturer Continuity: Microchip Technology manufactures both parts, maintaining consistent design documentation, application support, and supply chain relationships.

REACH Compliance: The USB5734/MRD02 carries REACH Unaffected status, confirming compliance with current environmental and regulatory requirements applicable to electronic components.

Frequently Asked Questions (FAQ)

Q: Can the USB5734/MRD02 be used as a direct replacement for the USB5734/MRD01?

A: The USB5734/MRD02 is the manufacturer-recommended substitute. Both parts share identical package specifications (64-VFQFN Exposed Pad, 9x9 millimeter dimensions), enabling mechanical and thermal compatibility.
