Ordering Code Difference
TUSB3410IRHB vs TUSB3410VFG4: What Is the Difference?
The TUSB3410 family has several ordering variants that mainly differ by package, temperature range, packing format, and environmental suffix. This page helps compare TUSB3410IRHB, TUSB3410IRHBT, TUSB3410IRHBR, and TUSB3410RHBG4 for sourcing and replacement decisions.

|---|---|---|---|
This PartTUSB3410IRHB | Base reference | USB-to-Serial Port Controller, QFN-32, Industrial Temp (-40°C~85°C) | |
TUSB3410VFG4 | Same core device as TUSB3410VF, with G4 environmental/lead-free ordering suffix | Usually interchangeable with TUSB3410VF if RoHS and traceability requirements are confirmed. |
The TUSB3410 family has four primary ordering variants that mainly differ by package, temperature range, and packing format. For the RHB package versions, TUSB3410IRHB is the base industrial-temperature 32-VQFN option, while TUSB3410IRHBT and TUSB3410IRHBR are packing variants used for tape-and-reel ordering. The G4 suffix, such as in TUSB3410RHBG4, historically indicates a Green / lead-free / RoHS-related ordering version and does not normally change the device function.
For replacement or sourcing, always confirm the same base device, package code, temperature range, packing requirement, and RoHS / compliance status before approval.

The TUSB3410 family has four primary variants differing in package and temperature range:
- VF — TSSOP-32, Commercial (0~70°C)
- RHB — QFN-32, Commercial (0~70°C)
- IVF — TSSOP-32, Industrial (-40~85°C)
- IRHB — QFN-32, Industrial (-40~85°C)
"I" = industrial temp. TSSOP for prototyping, QFN for space-constrained designs.
