FT600Q-T USB 3.0 FIFO Interface IC Equivalent & Substitute Parts

Part Overview

The FT600Q-T is a USB Bridge interface IC manufactured by FTDI that provides USB 3.0 to FIFO connectivity in a 56-QFN package. This component functions as a USB to FIFO bridge, enabling high-speed data transfer between USB 3.0 host systems and FIFO-based applications. The FT600Q-T is currently discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FT600Q-T are identified based on strict electrical and mechanical parameter matching within the FT60x series. The primary substitution criterion is functional equivalence across the following parameters:

• USB 3.0 protocol compliance
• FIFO interface architecture
• 56-QFN (7x7) package with exposed pad
• Supply voltage range: 1.65V ~ 3.6V
• Operating temperature range: -40°C ~ 85°C
• RoHS3 compliance and REACH unaffected status
• Moisture sensitivity level MSL 3

The FT600Q-B-T qualifies as a direct substitute based on identical electrical specifications, package geometry, and functional characteristics. The primary distinction is packaging format (Tray vs. standard packaging) and product status (Active vs. Discontinued).

Parameter Comparison

Engineering Selection Recommendations

The FT600Q-B-T is a direct functional equivalent to the FT600Q-T. Both components share identical electrical specifications, package geometry, and interface characteristics. The FT600Q-B-T is currently in active production status, whereas the FT600Q-T is discontinued at DiGi Electronics.

Selection of the FT600Q-B-T for new designs or replacement applications is supported by:

• Identical USB 3.0 FIFO bridge functionality
• Matching 56-QFN (7x7) package footprint and pinout
• Equivalent supply voltage and operating temperature ranges
• Identical RoHS3 and REACH compliance certifications
• Active product status ensuring ongoing availability and supply chain continuity

The only distinction is packaging format (Tray for FT600Q-B-T). This difference does not affect electrical or mechanical compatibility in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the FT600Q-B-T be used as a direct replacement for the FT600Q-T?

A: Yes. Both parts are electrically and mechanically identical. They share the same USB 3.0 FIFO bridge function, 56-QFN package, supply voltage range (1.65V ~ 3.6V), and operating temperature range (-40°C ~ 85°C). The FT600Q-B-T is the active production equivalent.

Q: What is the difference between FT600Q-T and FT600Q-B-T?

A: The primary difference is packaging format. The FT600Q-T uses standard packaging, while the FT600Q-B-T is supplied in Tray format. Product status also differs: FT600Q-T is discontinued at DiGi Electronics, while FT600Q-B-T is active. All electrical and functional specifications are identical.

Q: Are the pinouts identical between these parts?

A: Yes. Both components use the 56-QFN (7x7) package with exposed pad. The pinout and footprint are identical, enabling direct PCB-level substitution without layout modifications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both FT600Q-T and FT600Q-B-T are ROHS3 compliant, REACH unaffected, and carry MSL 3 (168 Hours) moisture sensitivity ratings.

Q: Which part should be selected for new designs?

A: The FT600Q-B-T should be selected for new designs due to its active production status and guaranteed supply chain availability.
