TL16C752CIPFBR Equivalent & Substitute Parts

Part Overview

The TL16C752CIPFBR is a dual-channel UART interface IC manufactured by Texas Instruments, designed for RS485 serial communication applications. This 48-TQFP surface-mount device integrates dual universal asynchronous receiver-transmitter (DUART) functionality with 64-byte FIFO buffers, supporting data rates up to 3 Mbps. The part is currently in active production status with 1802 units in stock.

Substitute parts become necessary when the primary part experiences supply constraints, when design requirements demand enhanced performance specifications, or when alternative packaging formats are required for manufacturing optimization.

Substitute Part Grouping Explanation

Substitute parts for the TL16C752CIPFBR are classified into two categories based on functional and compliance alignment:

Parametric Equivalent (Direct Substitution): The TL16C752CIPFBRQ1 maintains identical electrical specifications and package configuration as the primary part. This variant adds automotive-grade qualification (AEC-Q100) and is suitable for applications requiring automotive compliance. All core parameters—channel count, FIFO size, protocol support, voltage range, and data rate—remain unchanged.

Manufacturer-Recommended Alternatives (Enhanced Performance): The XR16L2750IM-F, XR16M752IM48-F, XR68M752IM48-F, and XR68M752IM48TR-F are MaxLinear alternatives that maintain the same 48-TQFP package footprint and dual-channel DUART architecture. These parts expand protocol support to include RS232 and RS422 in addition to RS485, and offer higher maximum data rates (6.25 Mbps to 16 Mbps). Voltage supply ranges vary by model. The XR68M752IM48TR-F is available in Tape & Reel packaging, matching the primary part's format.

Substitution eligibility is determined by:

• Identical package type (48-TQFP)
• Dual-channel UART architecture
• 64-byte FIFO buffer
• RS485 protocol support (minimum requirement)
• Compatible supply voltage overlap
• Surface-mount technology

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (No Design Changes Required): The TL16C752CIPFBRQ1 is the optimal choice when automotive-grade qualification is required. This part maintains 100% electrical and mechanical compatibility with the primary part while adding AEC-Q100 certification for automotive applications. Both parts share identical supply voltage ranges (1.62V ~ 5.5V) and performance specifications.

For Enhanced Performance Applications: The XR68M752IM48TR-F offers the best compatibility match among MaxLinear alternatives when Tape & Reel packaging is required. This part maintains the same packaging format as the primary part while providing 16 Mbps data rate capability and expanded protocol support (RS232, RS422, RS485). The supply voltage range (1.62V ~ 3.63V) overlaps with the primary part's lower operating range.

For Tray-Packaged Alternatives: The XR16L2750IM-F provides a mid-range performance option with 6.25 Mbps data rate and dual protocol support (RS232, RS485). The XR16M752IM48-F and XR68M752IM48-F both deliver 16 Mbps performance with comprehensive protocol support (RS232, RS422, RS485) but operate within a narrower voltage range (1.62V ~ 3.63V).

Compliance Considerations: All substitute parts maintain ROHS3 compliance. The primary part and TL16C752CIPFBRQ1 feature MSL-2 rating (1 Year), while MaxLinear alternatives carry MSL-3 rating (168 Hours), requiring adjusted moisture handling procedures during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can the TL16C752CIPFBRQ1 be used as a direct drop-in replacement? A: Yes. The TL16C752CIPFBRQ1 maintains identical electrical specifications, package configuration, and pin assignments. The only difference is the addition of AEC-Q100 automotive qualification. No circuit modifications are required.

Q: What are the key differences between Texas Instruments and MaxLinear UART options? A: MaxLinear alternatives offer higher data rates (6.25 Mbps to 16 Mbps versus 3 Mbps) and expanded protocol support. However, some MaxLinear variants operate within a narrower supply voltage range (1.62V ~ 3.63V). Verify your application's voltage requirements before substitution.

Q: Is the XR68M752IM48TR-F compatible with the primary part's packaging format? A: Yes. The XR68M752IM48TR-F is supplied in Tape & Reel format, matching the TL16C752CIPFBR's packaging. Other MaxLinear alternatives are supplied in Tray format and may require different handling procedures.

Q: What is the impact of different MSL ratings on component handling? A: The primary part and TL16C752CIPFBRQ1 have MSL-2 rating (1 Year shelf life). MaxLinear alternatives have MSL-3 rating (168 Hours shelf life). MSL-3 components require more stringent moisture control during storage and must be baked before reflow soldering if shelf life is exceeded.

Q: Can MaxLinear parts support RS485-only applications? A: Yes. All MaxLinear substitute parts support RS485 protocol. The additional RS232 and RS422 support does not interfere with RS485-only designs. Protocol selection is typically configured through firmware or pin strapping.

Q: What supply voltage range should I use for MaxLinear substitutes? A: The XR16L2750IM-F operates at 2.25V ~ 5.5V. The XR16M752IM48-F, XR68M752IM48-F, and XR68M752IM48TR-F operate at 1.62V ~ 3.63V. Ensure your application's supply voltage falls within the selected part's operating range.

Q: Are all substitute parts currently in active production? A: Yes. All listed substitute parts maintain active product status with current inventory availability.
