Key Parameters

Substitute Part Grouping Explanation

Substitution of the ATR4253C-PVQW is determined by the following critical parameters:

• Package Compatibility: Both parts must use the 16-VQFN (3x3) Exposed Pad surface mount package to ensure PCB layout and thermal management compatibility
• Manufacturer Consistency: Microchip Technology maintains the ATR4253 base product family, ensuring design continuity and supply chain reliability
• Regulatory Compliance: RoHS3 compliance and REACH unaffected status must be maintained for regulatory adherence
• Moisture Sensitivity: MSL 3 rating (168 Hours) must be preserved for storage and handling requirements
• Frequency Coverage: The substitute part must support FM band operation with frequency range encompassing or exceeding the original 76MHz ~ 108MHz specification

The ATR4253C-PVQW-1 meets all substitution criteria as an active product variant within the same base product family, offering extended frequency coverage while maintaining identical package, compliance, and environmental specifications.

Parameter Comparison

Engineering Selection Recommendations

The ATR4253C-PVQW-1 is the direct substitute for the obsolete ATR4253C-PVQW. Both parts are manufactured by Microchip Technology and share identical package specifications, RoHS3 compliance, and moisture sensitivity ratings. The substitute part maintains active product status, ensuring long-term availability and supply chain continuity.

The ATR4253C-PVQW-1 provides extended frequency coverage (50MHz ~ 900MHz) compared to the original part's FM band specification (76MHz ~ 108MHz), offering broader application flexibility without compromising compatibility in FM-specific designs. Identical package geometry and exposed pad configuration ensure direct PCB layout compatibility.

Both parts meet ROHS3 and REACH regulatory requirements, maintaining compliance with current environmental and hazardous substance directives. The MSL 3 rating applies to both components, requiring identical storage and handling protocols.

Frequently Asked Questions (FAQ)

Q: Can the ATR4253C-PVQW-1 be used as a direct replacement for the ATR4253C-PVQW?

A: Yes. Both parts use the 16-VQFN (3x3) Exposed Pad package with identical pinout and thermal characteristics. The substitute part is manufactured by the same supplier and maintains all regulatory compliance certifications.

Q: What is the primary difference between these parts?
