FT232RL-REEL Equivalent & Substitute Parts

Part Overview

The FT232RL-REEL is a USB to UART interface bridge IC manufactured by FTDI in a 28-SSOP package with Cut Tape and Digi-Reel packaging. This device implements USB 2.0 Full Speed connectivity with UART serial interface capability, operating across a 3.3V to 5.25V supply range. The FT232RL-REEL is classified as "Not For New Designs," indicating it has been superseded in FTDI's product portfolio. Equivalent and substitute parts are necessary for applications requiring active product status, alternative packaging formats, or optimized electrical characteristics while maintaining functional compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FT232RL-REEL is determined by the following critical parameters: USB protocol implementation (USB 2.0), functional classification (USB to UART bridge), UART interface support, supply voltage compatibility (3.3V ~ 5.25V or subset thereof), operating temperature range (-40°C ~ 85°C), and regulatory compliance (ROHS3, REACH Unaffected, EAR99 ECCN classification).

Substitute parts are grouped into two categories:

Manufacturer Recommended Substitutes: Parts that maintain identical or superior electrical specifications and active product status. These include FT231XS-R and FT232RNL-REEL, which preserve core USB-to-UART functionality while offering either reduced package size or active lifecycle status.

Similar Packaging Variants: Parts that maintain identical electrical and functional specifications but differ in packaging format. FT232RL-TUBE represents the same die and electrical performance as FT232RL-REEL but supplied in Tube packaging instead of Cut Tape and Digi-Reel format.

Parameter Comparison

Engineering Selection Recommendations

For Active Product Lifecycle: FT231XS-R and FT232RNL-REEL both carry Active product status, making them suitable for new designs. FT231XS-R operates at reduced supply current (8mA versus 15mA) and features a smaller 20-SSOP package footprint, beneficial for power-constrained or space-limited applications. FT232RNL-REEL maintains identical electrical specifications to FT232RL-REEL while providing active lifecycle support, making it the direct functional equivalent for applications requiring the 28-SSOP form factor.

For Packaging Compatibility: FT232RL-TUBE provides identical electrical and functional performance to FT232RL-REEL but in Tube packaging format. This substitution applies only when Tube packaging meets assembly and handling requirements.

For Legacy System Maintenance: FT232RL-REEL and FT232RL-TUBE remain available for existing designs. Both maintain ROHS3 compliance and identical electrical specifications, supporting continued production of established products.

All substitute parts maintain USB 2.0 compliance, ROHS3 certification, and REACH Unaffected status, ensuring regulatory consistency across substitution scenarios.

Frequently Asked Questions (FAQ)

Q: Can FT231XS-R directly replace FT232RL-REEL in existing designs?

A: FT231XS-R maintains USB 2.0 protocol, USB-to-UART bridge function, and UART interface compatibility. However, it uses a 20-SSOP package versus the 28-SSOP package of FT232RL-REEL. Pin count and layout differ, requiring PCB redesign. Supply voltage range is 3.3V to 5V (versus 3.3V to 5.25V), and supply current is reduced to 8mA. Functional substitution is possible only with circuit board modification.

Q: What is the difference between FT232RL-REEL and FT232RL-TUBE?

A: Both parts are electrically and functionally identical. The difference is packaging format: FT232RL-REEL is supplied in Cut Tape and Digi-Reel format, while FT232RL-TUBE is supplied in Tube format. Selection depends on assembly equipment compatibility and handling requirements.

Q: Why is FT232RNL-REEL recommended over FT232RL-REEL?

A: FT232RNL-REEL carries Active product status, while FT232RL-REEL is classified as "Not For New Designs." Both maintain identical electrical specifications, 28-SSOP package format, and Cut Tape/Digi-Reel packaging. For new designs, FT232RNL-REEL provides assured long-term availability and manufacturer support.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. FT231XS-R, FT232RNL-REEL, and FT232RL-TUBE all carry ROHS3 Compliant status with Moisture Sensitivity Level 3 (168 Hours), matching FT232RL-REEL compliance requirements.

Q: What supply voltage range applies to FT231XS-R?

A: FT231XS-R operates across 3.3V to 5V. This is narrower than FT232RL-REEL (3.3V to 5.25V). Applications requiring operation above 5V cannot use FT231XS-R as a substitute.
