PIN-TO-PIN ALTERNATIVE
SIT1050QT is a Chinese-manufactured pin-to-pin drop-in replacement for TJA1050T (NXP).
A textbook domestic CAN cross-reference: same pins, same rating, better ESD, available now.
SIT1050QT — Alternative to TJA1050T
SIT1050QT from SIT {BRAND} is supplied by JTDZ Tech (Shenzhen Jingteng Electronics) as a cost-effective, short-lead-time alternative to the imported TJA1050T (NXP). Chinese-sourced semiconductors have moved well beyond "cheap substitute" status: the parts below are production-validated in industrial, automotive and consumer designs, and they remove both the allocation risk and the long lead times that come with imported.

What to check before substituting SIT1050QT for TJA1050T
- Pin definitions, supply voltage, data rate, temperature range, bus withstand voltage and common-mode voltage all match the TJA1050, so it is a true pin-to-pin swap with no PCB change.
- Fully compliant with ISO 11898. Dominant timeout is included.
- Silent mode means a node that is not powered does not disturb the bus.
- Bus fault voltage of -40 V to +40 V exceeds some international equivalents.
- Can also serve as a TJA1051 substitute in a number of applications.
Typical Applications
- Automotive body and powertrain networks
- Truck and bus systems
- Industrial control, PLC and servo drives
- Inverters, touch panels and power supplies
