Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TUSB1004RNQT are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters that define functional interchangeability:

Electrical Parameters:

• Data Rate (Max): 10 Gbps
• Number of Channels: 4
• Input/Output Configuration: Differential
• Delay Time: 300 ps
• Signal Conditioning: Input Equalization, Output De-Emphasis
• Capacitance - Input: 10 pF
• Voltage - Supply: 3V ~ 3.6V
• Operating Temperature: 0°C ~ 70°C (TA)

Mechanical Parameters:

• Package / Case: 40-WFQFN Exposed Pad
• Supplier Device Package: 40-WQFN (6x4)
• Mounting Type: Surface Mount

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• REACH Status: REACH Unaffected

All substitute parts must maintain identical values across these parameters to ensure direct replacement capability without circuit redesign or performance impact.

Parameter Comparison

Engineering Selection Recommendations

Both the TUSB1004RNQT and TUSB1004RNQR are Active status products from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts should be based on inventory availability and supply chain considerations.

The TUSB1004RNQR offers higher inventory availability at 3964 pieces compared to 1101 pieces for the TUSB1004RNQT. Both components maintain full compliance with ROHS3 and REACH requirements, with MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage and handling.

For applications requiring 10 Gbps USB 3.2 signal conditioning with 4-channel differential buffering and ReDriver functionality, either part provides equivalent performance in the 40-WQFN (6x4) surface mount package. The identical delay time of 300 ps, input equalization, and output de-emphasis characteristics ensure consistent signal integrity across both options.
