Key Parameters

Substitute Part Grouping Explanation

Substitution of the USB5916T-I/KD is determined by the following critical parameters:

• Package Compatibility: Both main and substitute parts must use the 100-VQFN (12x12) form factor with exposed pad to ensure PCB layout compatibility without redesign.
• Functional Equivalence: The substitute must perform USB Hub Controller functionality with USB protocol support.
• Interface Support: The substitute must support I2C and SPI interfaces as minimum requirements for system integration.
• Voltage Supply Range: The substitute must operate within or encompass the supply voltage requirements of the original design.
• Operating Temperature Range: The substitute must maintain the -40°C ~ 85°C operating temperature specification.
• Regulatory Compliance: The substitute must maintain ROHS3 compliance and REACH unaffected status for regulatory continuity.

The USB5916CT-I/KD qualifies as a direct substitute based on these parameters while offering enhanced functionality and active product status.

Engineering Selection Recommendations

The USB5916CT-I/KD is the recommended substitute for the obsolete USB5916T-I/KD based on the following engineering criteria:

• Product Status: The substitute maintains active product status with Microchip Technology, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both components maintain identical ROHS3 compliance and REACH unaffected status, eliminating regulatory risk in substitution.
• Package Compatibility: Identical 100-VQFN (12x12) packaging with exposed pad ensures direct PCB layout compatibility without design modification.
• Functional Enhancement: The substitute supports additional interface protocols (SMBus, UART) and USB 2.0 standard alongside USB 3.1, providing backward compatibility and expanded system integration options.
• Voltage Supply Compatibility: The substitute voltage range (1.08V ~ 1.32V, 3V ~ 3.6V) encompasses the original specification (1.2V, 3.3V), ensuring power supply compatibility.
• Thermal Specification: Identical operating temperature range (-40°C ~ 85°C) maintains thermal design requirements.

Frequently Asked Questions (FAQ)

Q: Can the USB5916CT-I/KD be used as a direct replacement for the USB5916T-I/KD without PCB modifications?

A: Yes. Both components use the identical 100-VQFN (12x12) package with exposed pad configuration, enabling direct substitution without PCB layout changes.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete vs. active) and interface capabilities. The USB5916CT-I/KD adds SMBus and UART interface support and includes USB 2.0 standard support in addition to USB 3.1. The voltage supply range is specified as a continuous range (1.08V ~ 1.32V, 3V ~ 3.6V) rather than discrete values.

Q: Are there any compliance concerns when substituting the USB5916CT-I/KD for the USB5916T-I/KD?

A: No. Both components maintain identical ROHS3 compliance and REACH unaffected status, eliminating regulatory compliance concerns in the substitution.

Q: Does the substitute part support the same I2C and SPI interfaces as the original?

A: Yes. The USB5916CT-I/KD supports I2C and SPI interfaces as required by the original design, with additional SMBus and UART interface options available.

Q: What is the moisture sensitivity level for both parts?

A: Both the USB5916T-I/KD and USB5916CT-I/KD have an MSL rating of 3 (168 Hours), requiring identical handling and storage conditions.

Q: Is the operating temperature range identical between the two parts?

A: Yes. Both components operate across the -40°C ~ 85°C temperature range, maintaining thermal design compatibility.
