Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSU6712YFPRB is determined by compatibility across the following critical parameters:

Package Compatibility: Both the main part and substitute must utilize the 25-DSBGA package format to ensure mechanical and electrical fit within existing PCB layouts.

Interface Protocol Support: The substitute must support the same communication protocols (I2C, UART, USB 2.0) required by the application.

Operating Temperature Range: The substitute must maintain the -40°C to 85°C operating temperature specification to ensure reliability across the intended thermal environment.

Surface Mount Capability: The substitute must be available in surface mount configuration to align with modern manufacturing processes.

Compliance Standards: Both components must maintain ROHS3 compliance and MSL Level 1 rating to satisfy regulatory and environmental requirements.

The TSU6721YFFR is identified as a manufacturer-recommended substitute based on these parameters, though with notable differences in switch circuit configuration and supply voltage range that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The TSU6721YFFR is available as an active product from Texas Instruments, providing supply chain continuity for applications currently using the obsolete TSU6712YFPRB. Both components maintain identical operating temperature specifications (-40°C to 85°C) and equivalent compliance certifications (ROHS3, MSL Level 1, REACH Unaffected).

Critical design considerations exist due to parameter differences. The TSU6721YFFR operates at a higher supply voltage range (4V to 6.5V) compared to the TSU6712YFPRB (1.65V to 3.6V), requiring voltage regulation adjustments in the power delivery network. The switch circuit configuration differs from SP4T to SP3T, and channel count increases from 1 to 2, necessitating firmware or application logic modifications to accommodate the expanded switching capability.

Both components share the 25-DSBGA package format and surface mount configuration, enabling direct PCB layout compatibility. The TSU6721YFFR introduces additional features including Charger Detection and ID Pass Switch functionality, which may provide enhanced capability for USB power delivery applications.

Frequently Asked Questions (FAQ)

Q: Can the TSU6721YFFR be used as a direct pin-for-pin replacement for the TSU6712YFPRB?

A: Both components utilize the 25-DSBGA package, providing mechanical compatibility. However, the supply voltage range differs significantly (1.65V–3.6V versus 4V–6.5V), requiring power supply circuit modifications. The switch circuit configuration change from SP4T to SP3T and increased channel count from 1 to 2 necessitate application-level firmware or logic adjustments.

Q: What are the key electrical differences between these components?

A: The primary electrical differences are supply voltage range and switch circuit topology. The TSU6712YFPRB operates at lower voltages (1.65V–3.6V) with single-channel SP4T switching, while the TSU6721YFFR requires higher supply voltages (4V–6.5V) and provides dual-channel SP3T switching with additional charger detection and ID pass switch features.

Q: Are both components compliant with current regulatory standards?

A: Both the TSU6712YFPRB and TSU6721YFFR maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status, satisfying current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the packaging format for both components?

A: Both components are supplied in 25-DSBGA (25-pin Dual Small Ball Grid Array) packages in surface mount configuration. The TSU6712YFPRB uses 25-XFBGA variant, while the TSU6721YFFR uses 25-UFBGA variant, maintaining compatibility with standard BGA assembly processes.

Q: Why is the TSU6712YFPRB classified as obsolete?

A: The TSU6712YFPRB is no longer in active production. The TSU6721YFFR represents the active product line continuation from Texas Instruments, offering enhanced functionality and ongoing supply availability for new designs and legacy system support.
