Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the USB2512I-AEZG is determined by strict adherence to the following parameters:

• Base Product Number: Must be USB2512 to ensure functional equivalence as a dual-port USB 2.0 hub controller
• Package Type: Must be 36-VFQFN Exposed Pad with 36-QFN (6x6) supplier device package for PCB layout compatibility
• Interface Standard: Must support USB 2.0 protocol
• Voltage Supply Range: Must operate within 3V ~ 3.6V
• Operating Temperature Range: Must support -40°C ~ 85°C
• Compliance: Must maintain ROHS3 compliance and REACH unaffected status

The USB2512BI-AEZG meets all substitution criteria and is classified as a direct equivalent based on these parameters.

Engineering Selection Recommendations

The USB2512BI-AEZG is the direct substitute for the obsolete USB2512I-AEZG. Selection of this alternative is supported by:

• Product Status: The substitute part is active and in production, ensuring long-term availability and supply chain continuity
• Regulatory Compliance: Both parts maintain identical ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements
• Functional Equivalence: Identical base product number, interface standard, package type, and electrical operating parameters ensure drop-in compatibility
• Supply Availability: The substitute part has significantly higher inventory (6765 pcs) compared to the obsolete part (902 pcs), providing reliable sourcing

The USB2512BI-AEZG operates at a lower supply current (60mA versus 95mA), which represents an operational improvement without compromising functionality.

Frequently Asked Questions (FAQ)

Q: Can the USB2512BI-AEZG be used as a direct replacement for the USB2512I-AEZG?

A: Yes. Both parts share the same base product number (USB2512), identical package type (36-VFQFN Exposed Pad, 36-QFN 6x6), matching voltage supply range (3V ~ 3.6V), and equivalent operating temperature specifications (-40°C ~ 85°C). PCB layout and schematic integration require no modification.

Q: What is the difference in current supply between these parts?

A: The USB2512I-AEZG specifies 95mA supply current, while the USB2512BI-AEZG specifies 60mA. The lower current requirement of the substitute part does not affect functional capability and may reduce thermal load in the application circuit.

Q: Are there packaging differences between these parts?

A: The USB2512BI-AEZG is supplied in Tray packaging, while the USB2512I-AEZG packaging format is not specified. Both parts use identical 36-QFN (6x6) device packages suitable for surface-mount assembly.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the USB2512I-AEZG and USB2512BI-AEZG are ROHS3 compliant, REACH unaffected, and maintain identical Moisture Sensitivity Level 3 (168 Hours) specifications.

Q: Why is the USB2512I-AEZG classified as obsolete?

A: The USB2512I-AEZG is no longer in active production. The USB2512BI-AEZG is the active production equivalent and is the recommended selection for new designs and ongoing system support.
