Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FT232RQ-TRAY is determined by the following critical parameters:

Primary Compatibility Criteria:

• USB 2.0 protocol and USB to UART bridge function
• UART interface type
• Operating temperature range: -40°C ~ 85°C
• RoHS3 compliance and REACH unaffected status
• Moisture Sensitivity Level 3 (168 Hours)

Secondary Compatibility Criteria:

• Voltage supply range overlap (minimum 3.3V support required)
• Package type and pin count compatibility
• Tray packaging format

The FT232RQ-TRAY has two identified substitutes within the FTDI USBmadeEZ-UART series:

1. FT232RNQ-TRAY - Direct functional equivalent with identical electrical specifications and package footprint. Maintains Active product status.

2. FT231XQ-T - Functional equivalent with reduced pin count (20-QFN vs 32-QFN) and lower supply current (8mA vs 15mA). Represents a more integrated design within the FT-X/X-Chip series.

Parameter Comparison

Engineering Selection Recommendations

FT232RNQ-TRAY is the primary substitute for direct replacement applications. This part maintains identical electrical specifications, package footprint, and pin configuration as the FT232RQ-TRAY while offering Active product status. No PCB redesign is required. Both parts are ROHS3 compliant and REACH unaffected, with equivalent moisture sensitivity ratings.

FT231XQ-T is suitable for applications where PCB redesign is feasible. This part reduces board space requirements through a smaller 20-QFN package and decreases power consumption to 8mA. The voltage supply range is slightly reduced to 3.3V ~ 5V, requiring verification that application power supplies meet this specification. The FT231XQ-T is part of the newer FT-X/X-Chip series and carries Active product status.

Selection between FT232RNQ-TRAY and FT231XQ-T depends on design constraints: choose FT232RNQ-TRAY for drop-in replacement without redesign; choose FT231XQ-T for new designs or redesigns prioritizing reduced power consumption and board space.

Frequently Asked Questions (FAQ)

Q: Can FT232RNQ-TRAY replace FT232RQ-TRAY without PCB modifications?

A: Yes. FT232RNQ-TRAY is electrically and mechanically identical to FT232RQ-TRAY, with the same 32-QFN (5x5) package footprint, pin configuration, voltage supply range (3.3V ~ 5.25V), and supply current (15mA). No PCB redesign is necessary.

Q: What are the key differences between FT232RNQ-TRAY and FT231XQ-T?

A: FT232RNQ-TRAY maintains the 32-QFN (5x5) package with 15mA supply current. FT231XQ-T uses a smaller 20-QFN (4x4) package with reduced supply current of 8mA and a slightly narrower voltage supply range (3.3V ~ 5V vs 3.3V ~ 5.25V). FT231XQ-T requires PCB redesign due to different package dimensions and pin count.

Q: Are all three parts RoHS3 compliant?

A: Yes. FT232RQ-TRAY, FT232RNQ-TRAY, and FT231XQ-T are all ROHS3 compliant and REACH unaffected.

Q: What is the moisture sensitivity level for these parts?

A: All three parts have Moisture Sensitivity Level 3 with a 168-hour floor life rating.

Q: Which substitute should I choose for a new design?

A: For new designs, either FT232RNQ-TRAY or FT231XQ-T are appropriate, both carrying Active product status. FT232RNQ-TRAY is recommended if your existing design uses the 32-QFN package. FT231XQ-T is recommended if you can accommodate the 20-QFN package and benefit from reduced power consumption.

Q: Is the voltage supply range difference between FT232RNQ-TRAY and FT231XQ-T significant?

A: FT232RNQ-TRAY supports 3.3V ~ 5.25V while FT231XQ-T supports 3.3V ~ 5V. If your application requires operation above 5V, FT232RNQ-TRAY is required. For standard 3.3V or 5V supply applications, both parts are compatible.
