Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TJA1145ATK/FD/0Z is determined by strict equivalence across the following critical parameters:

• Protocol specification (CANbus)
• Channel configuration (1/1 drivers/receivers)
• Duplex mode (Full)
• Data rate capability (5 Mbps)
• Supply voltage range (4.5V to 5.5V)
• Operating temperature range (-40°C to 150°C)
• Receiver hysteresis (800 mV)
• Package type (14-VDFN Exposed Pad / 14-HVSON 3x4.5)
• Automotive grade and AEC-Q100 qualification
• RoHS3 compliance

The TJA1145ATK/0Z meets all substitution criteria as a parametric equivalent, differing only in packaging designation suffix while maintaining identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the TJA1145ATK/FD/0Z and TJA1145ATK/0Z are active production parts from NXP USA Inc. with identical electrical specifications and automotive qualification. Selection between these parts should be based on:

• Inventory availability and lead time requirements
• Packaging designation requirements specific to your supply chain documentation
• Compliance with your organization's approved parts list (APL) or engineering change order (ECO) procedures

Both parts maintain full AEC-Q100 automotive qualification and ROHS3 compliance, ensuring equivalent reliability and regulatory status for automotive applications.

Frequently Asked Questions (FAQ)

Q: Can TJA1145ATK/0Z be used as a direct replacement for TJA1145ATK/FD/0Z?

A: Yes. Both parts are parametric equivalents with identical electrical performance, operating characteristics, and package specifications. The difference in part number suffix reflects packaging designation only and does not affect functional compatibility.

Q: Are there any differences in automotive qualification between these parts?

A: No. Both parts carry AEC-Q100 qualification and are rated for automotive-grade applications across the full temperature range of -40°C to 150°C.

Q: What is the significance of the packaging suffix in the part number?

A: The suffix designates the packaging format and distribution method. Both suffixes represent the same 14-HVSON (3x4.5) physical package and 14-VDFN Exposed Pad case type.

Q: Are both parts RoHS3 compliant?

A: Yes. Both TJA1145ATK/FD/0Z and TJA1145ATK/0Z are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the maximum data rate supported by these transceivers?

A: Both parts support a maximum data rate of 5 Mbps on the CANbus protocol.

Q: Can these parts operate outside the 4.5V to 5.5V supply range?

A: No. Both parts are specified for operation within the 4.5V to 5.5V supply voltage range only.
