Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: USB5744/2GTB

The USB5744/2GTB is the manufacturer-recommended substitute for the obsolete USB5744/2GTA. This part maintains full electrical and mechanical compatibility while offering Active product status, ensuring long-term availability and supply chain stability. The USB5744/2GTB carries REACH Unaffected compliance certification, supporting regulatory requirements for new designs and production.

Secondary Recommendations: USB5744/2GD02 and USB5744T/2GD02

Both USB5744/2GD02 and USB5744T/2GD02 are parametric equivalents that satisfy all electrical and mechanical substitution criteria. These parts are Active products with REACH Unaffected status. The USB5744T/2GD02 variant may represent a temperature-grade or tape-and-reel packaging option within the same functional specification.

Selection Basis:

Component selection should prioritize Active product status parts to ensure sustained availability. All three substitute options provide identical electrical performance, interface capability, and package compatibility. REACH Unaffected certification status supports compliance with environmental and regulatory standards for manufacturing and distribution.

Frequently Asked Questions (FAQ)

Q: Can the USB5744/2GTB directly replace the USB5744/2GTA in existing designs?

A: Yes. The USB5744/2GTB maintains identical electrical specifications, interface protocols (USB 2.0, USB 3.2, Serial, SMBus, SPI), supply voltage ranges (1.08V ~ 1.32V, 3V ~ 3.6V), operating temperature range (0°C ~ 70°C), and 56-VQFN (7x7) package configuration. No design modifications are required.

Q: What is the difference between USB5744/2GD02 and USB5744T/2GD02?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The designation difference may indicate packaging format or temperature-grade variants. Consult the specific datasheet for packaging and delivery format details.

Q: Are all substitute parts REACH compliant?

A: The USB5744/2GTB, USB5744/2GD02, and USB5744T/2GD02 all carry REACH Unaffected status. This certification confirms compliance with REACH regulatory requirements for substances of concern.

Q: Does the package type remain the same across all substitute parts?

A: Yes. All substitute parts use the 56-VQFN (7x7) package with exposed pad. Pin count, pitch, and mechanical dimensions are identical, ensuring PCB layout compatibility without modification.

Q: Why is the USB5744/2GTA marked as Obsolete?

A: Obsolete status indicates the part is no longer in active production. Substitute parts with Active status provide equivalent functionality while ensuring ongoing availability and manufacturer support.

Q: Can I use USB5744/2GD02 and USB5744T/2GD02 interchangeably?

A: Both parts meet identical electrical and mechanical specifications. Interchangeability depends on specific packaging and delivery requirements. Verify packaging format and lead time availability for your production schedule.
