Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI3USB9281AGEEX is determined by strict equivalence across the following critical parameters:

• Functional classification: USB 2.0 port detection PMIC
• Electrical specifications: 3V to 5.5V supply voltage range
• Thermal operating range: -40°C to 85°C
• Package form factor: 15-CSP (1.5x2.0mm) with 15-XFBGA, WLCSP case designation
• Compliance standards: ROHS3 compliance, REACH unaffected status
• Moisture sensitivity: MSL 1 (unlimited shelf life)
• Base product family: PI3USB9281 series

The PI3USB9281CGEEX meets all these criteria and maintains identical electrical and mechanical specifications while offering active product status and current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

The PI3USB9281CGEEX is the direct equivalent substitute for the obsolete PI3USB9281AGEEX. Both components share identical electrical specifications, thermal ratings, package geometry, and compliance certifications. The primary distinction is product lifecycle status: the PI3USB9281CGEEX maintains active manufacturing status with current inventory availability, whereas the PI3USB9281AGEEX is obsolete.

For new designs and production continuity, the PI3USB9281CGEEX is the appropriate selection. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for mobile communications applications. The MSL 1 rating ensures unlimited shelf life for both variants, eliminating moisture-related storage constraints.

Frequently Asked Questions (FAQ)

Q: Can the PI3USB9281CGEEX directly replace the PI3USB9281AGEEX in existing designs?

A: Yes. The PI3USB9281CGEEX is a direct functional and mechanical equivalent. All electrical parameters, package dimensions, pin configurations, and compliance certifications are identical. No design modifications are required.

Q: What is the difference between the AGEEX and CGEEX part number suffixes?

A: The suffix designates manufacturing revision or product lifecycle stage within the PI3USB9281 base product family. Both variants maintain identical specifications for the USB 2.0 port detection function.

Q: Are there any supply chain considerations when transitioning from PI3USB9281AGEEX to PI3USB9281CGEEX?
