Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the USB2514I-AEZG is determined by the following critical parameters:

• USB 2.0 protocol compliance
• Hub controller function classification
• Voltage supply range: 3V ~ 3.6V
• Operating temperature range: -40°C ~ 85°C
• 36-QFN package footprint compatibility
• RoHS3 compliance and MSL 3 rating

The USB2513BI-AEZG qualifies as a parametric equivalent based on matching voltage supply, operating temperature, package dimensions, and regulatory compliance. The primary functional difference is port count: the USB2514I-AEZG provides 4 ports, while the USB2513BI-AEZG provides 3 ports. This distinction requires design-level evaluation to determine suitability for specific applications.

Parameter Comparison

Engineering Selection Recommendations

The USB2513BI-AEZG is available in active product status with 17,934 units in stock, compared to the obsolete USB2514I-AEZG with 1,304 units available. Both components maintain ROHS3 compliance and identical electrical operating parameters.

Selection of the USB2513BI-AEZG requires confirmation that the 3-port configuration meets application requirements. The reduced port count represents the primary design consideration. Both components share identical voltage supply ranges, temperature operating windows, package footprints, and regulatory certifications, supporting electrical and thermal compatibility.

Frequently Asked Questions (FAQ)

Q: Can the USB2513BI-AEZG directly replace the USB2514I-AEZG in existing designs?

A: Electrical and thermal compatibility is supported. The 3-port versus 4-port configuration difference requires design-level assessment. PCB layout and firmware may require modification to accommodate the port count reduction.

Q: Are the package dimensions identical between these parts?

A: Both components use 36-QFN (6x6) packages with exposed pads. The footprint is compatible for PCB placement. Verify supplier device package specifications with your component distributor.

Q: What is the significance of the product status difference?

A: The USB2514I-AEZG is classified as obsolete, indicating discontinued manufacturing. The USB2513BI-AEZG maintains active product status with current manufacturing support and higher inventory availability.

Q: Do both parts meet the same compliance requirements?

A: Both components are ROHS3 compliant with MSL 3 (168 Hours) ratings. Regulatory certifications and environmental compliance are equivalent.

Q: What supply voltage is required for operation?

A: Both the USB2514I-AEZG and USB2513BI-AEZG operate within the 3V to 3.6V supply range. Verify your system power delivery design supports this voltage specification.
