Frequently Asked Questions (FAQ)

Q: Can TUSB1105RTZR and TUSB1106RTZR be used interchangeably with TUSB1105RTZRG4?

A: Yes. Both parts are parametric equivalents meeting identical electrical and mechanical specifications. The primary differences are product status (active vs. discontinued) and packaging format (Cut Tape/Digi-Reel vs. Tape & Reel).

Q: What is the difference between the packaging formats offered by the substitute parts?

A: TUSB1105RTZR is supplied in Cut Tape (CT) and Digi-Reel® formats, suitable for lower-volume or mixed-component orders. TUSB1106RTZR is supplied in Tape & Reel (TR) format, optimized for high-speed automated pick-and-place assembly equipment.

Q: Are the substitute parts compliant with the same environmental and regulatory standards?

A: Yes. Both TUSB1105RTZR and TUSB1106RTZR maintain ROHS3 compliance, REACH unaffected status, and MSL Level 1 (Unlimited) rating, identical to the original TUSB1105RTZRG4.

Q: What is the physical package compatibility between these parts?

A: All three parts use the 16-WQFN (3x3) surface mount package with exposed pad. PCB footprints and assembly processes are identical across all variants.

Q: Why is the original TUSB1105RTZRG4 discontinued?

A: Product discontinuation is determined by the manufacturer and distributor. Active substitute parts TUSB1105RTZR and TUSB1106RTZR provide equivalent functionality and are recommended for new designs and component replenishment.
