TUSB564RNQR Equivalent & Substitute Parts

Part Overview

The TUSB564RNQR is a crosspoint switch IC manufactured by Texas Instruments, designed for 1 x 4:4 signal routing applications. This logic component operates with a single supply voltage of 3V to 3.6V and is housed in a 40-WQFN (6x4) surface mount package with exposed pad. The device is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical specifications, package geometry, and functional circuit configurations are maintained across different packaging or tape formats.

Substitute Part Grouping Explanation

Substitute parts for the TUSB564RNQR are determined by strict equivalence in the following critical parameters:

• Electrical Specifications: Identical circuit configuration (1 x 4:4), voltage supply range (3V ~ 3.6V), and operating temperature range (0°C ~ 70°C)
• Package Geometry: Same physical package type (40-WQFN with exposed pad, 6x4 dimensions)
• Functional Classification: Same device type (Crosspoint Switch) with identical independent circuit count
• Compliance & Certifications: Matching RoHS status (ROHS3 Compliant) and MSL rating (1)
• Manufacturer Consistency: Same manufacturer (Texas Instruments) to ensure design validation and process consistency

The primary distinction between the main part and its substitute is the packaging format: the TUSB564RNQR is supplied in standard packaging, while the TUSB564RNQT is supplied in Tape & Reel (TR) format. Both variants share the identical base product number (TUSB564) and are functionally interchangeable at the component level.

Parameter Comparison

Engineering Selection Recommendations

Both TUSB564RNQR and TUSB564RNQT are active production devices from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts should be based on procurement and assembly requirements:

The TUSB564RNQR in standard packaging is suitable for applications requiring manual component handling, small-volume production, or evaluation purposes. The TUSB564RNQT in Tape & Reel format is optimized for automated pick-and-place assembly processes and high-volume manufacturing environments where tape-fed component delivery reduces handling time and improves assembly efficiency.

Both variants maintain full compliance with ROHS3 regulations and REACH directives, ensuring regulatory compatibility across applications. The MSL 1 rating indicates unlimited shelf life under standard storage conditions, eliminating moisture-related reflow constraints for both packaging formats.

Frequently Asked Questions (FAQ)

Q: Are TUSB564RNQR and TUSB564RNQT electrically identical?

A: Yes. Both parts share identical electrical specifications including circuit configuration (1 x 4:4), voltage supply range (3V ~ 3.6V), operating temperature range (0°C ~ 70°C), and functional performance as crosspoint switches.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. TUSB564RNQR is supplied in standard packaging, while TUSB564RNQT is supplied in Tape & Reel (TR) format for automated assembly processes. The physical component and pin configuration remain identical.

Q: Can I substitute TUSB564RNQT for TUSB564RNQR in my design?

A: Yes, at the component level. Both parts are functionally equivalent and will perform identically in the circuit. Substitution feasibility depends on your assembly process: standard packaging suits manual handling, while Tape & Reel format is designed for automated pick-and-place equipment.

Q: Are both parts RoHS compliant?

A: Yes. Both TUSB564RNQR and TUSB564RNQT are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for electronics manufacturing.

Q: What does MSL 1 rating mean for these parts?

A: MSL 1 indicates unlimited moisture sensitivity level, meaning these components have no moisture-related reflow constraints and can be stored indefinitely under standard conditions without requiring special desiccant packaging or baking procedures.

Q: Which part should I specify for high-volume production?

A: TUSB564RNQT in Tape & Reel format is recommended for high-volume manufacturing due to compatibility with automated assembly equipment and improved production efficiency.
