Substitute Part Grouping Explanation

Substitution of the SN65C1168EPW is determined by strict equivalence across the following critical parameters:

• Protocol support: RS422 and RS485 full-duplex operation
• Channel configuration: 2 drivers and 2 receivers
• Receiver hysteresis: 60 mV threshold
• Supply voltage range: 4.5V to 5.5V
• Operating temperature range: -40°C to 85°C
• Package form factor: 16-TSSOP surface mount
• Compliance certifications: ROHS3, REACH Unaffected, EAR99

All identified substitute parts maintain identical electrical and mechanical specifications across these parameters, enabling direct functional replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

SN65C1168EPWR (MFR Recommended): This Texas Instruments part carries Active product status and is available in Cut Tape and Digi-Reel packaging formats with 18,041 units in stock. It is the manufacturer-recommended substitute for the SN65C1168EPW and provides the highest availability for new designs and ongoing production.

ADM4168EBRUZ (Cross-Manufacturer Alternative): The Analog Devices Inc. equivalent maintains full parametric compatibility and Active product status with 18,142 units available. This option is suitable for applications where multi-source qualification is required or where Analog Devices supply chain relationships are established.

SN65C1168PW (Texas Instruments Alternative): This variant shares the same base product number as the SN65C1168EPW but carries Last Time Buy status with 3,170 units in stock. It is functionally equivalent but offers lower availability compared to the SN65C1168EPWR.

Frequently Asked Questions (FAQ)

Q: Can SN65C1168EPWR be used as a direct replacement for SN65C1168EPW?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications, package form factor, and compliance certifications. The primary difference is product status and packaging format. SN65C1168EPWR is in Active status and available in Cut Tape/Digi-Reel, while SN65C1168EPW is Last Time Buy in Tube packaging.

Q: What is the difference between the Texas Instruments and Analog Devices versions?

A: The ADM4168EBRUZ is manufactured by Analog Devices Inc. rather than Texas Instruments but maintains identical electrical and mechanical parameters. Both are ROHS3 compliant and rated for the same supply voltage, temperature range, and package specifications. Selection between manufacturers depends on supply chain strategy and existing qualification documentation.

Q: Are all substitute parts available in the same package?

A: All substitute parts use the 16-TSSOP surface mount package with identical dimensions (0.173" width, 4.40mm). Packaging format differs: SN65C1168EPW and SN65C1168PW are supplied in Tube, while SN65C1168EPWR is available in Cut Tape and Digi-Reel formats.

Q: Why is SN65C1168EPW in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this specific part number variant. The SN65C1168EPWR is the active replacement and should be used for new designs and future procurement.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All substitute parts share identical pinout, electrical characteristics, and package dimensions. No PCB layout modifications are required for substitution.
