Substitute Part Grouping Explanation

Substitute parts for the TJA1044VT/3Z are identified based on strict equivalence across the following critical parameters:

• Protocol: CANbus
• Number of Drivers/Receivers: 1/1
• Duplex: Half
• Data Rate: 5 Mbps
• Voltage - Supply: 4.75V ~ 5.25V
• Operating Temperature: -40°C ~ 150°C (TJ)
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Base Product Number: TJA1044
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitutes maintain identical electrical specifications, thermal operating range, and physical packaging. Substitution is valid when these parameters remain constant across part variants.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TJA1044VT/3Z, TJA1044T,118, and TJA1044T/1Z—are active products from NXP USA Inc. with identical electrical and mechanical specifications. Selection between these variants is based on availability and packaging designation. Each part maintains AEC-Q100 automotive qualification and ROHS3 compliance, ensuring suitability for automotive CANbus interface applications. The parts are functionally interchangeable in circuit designs where the 8-SOIC package, half-duplex CANbus protocol, and specified voltage and temperature ranges are required.

Frequently Asked Questions (FAQ)

Q: Can TJA1044T,118 be used as a direct replacement for TJA1044VT/3Z?

A: Yes. Both parts share identical electrical parameters, including protocol (CANbus), data rate (5 Mbps), supply voltage (4.75V ~ 5.25V), operating temperature range (-40°C ~ 150°C), and physical packaging (8-SOIC). The part number suffix indicates packaging designation only and does not affect functional performance.

Q: What is the difference between TJA1044VT/3Z and TJA1044T/1Z?

A: The parts are electrically and mechanically equivalent. Differences in part number suffixes (VT/3Z versus T/1Z) reflect packaging and tape reel configurations but do not alter transceiver functionality, electrical specifications, or thermal characteristics.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q100 automotive qualification and are graded for automotive use. Each operates across the full automotive temperature range of -40°C to 150°C junction temperature.

Q: Do these parts require different PCB layouts or design considerations?

A: No. All three parts use the identical 8-SOIC package with 0.154" width and 3.90mm body dimensions. PCB footprints, trace routing, and design considerations remain unchanged across all variants.

Q: What is the significance of the MSL rating for these parts?

A: All three parts carry MSL 1 (Unlimited), indicating unlimited shelf life without moisture absorption concerns. This simplifies inventory management and storage requirements for automotive manufacturing environments.
