If your design needs to push diagnostic data or firmware-over-CAN at the faster CAN FD payload phase, this part handles it without dropping frames. The 1/1 driver/receiver count covers a single CAN node — one bus line in, one bus line out, no redundant channels. If your BOM calls for AEC-Q100 on the CAN bus interface, this part checks that box without a waiver. The wettable flank feature allows automated optical inspection (AOI) of the solder joint on the side of the package, which is a requirement on many automotive assembly lines that cannot inspect a bottom-only termination. For the procurement file, this keeps the BOM line green on lifecycle reviews. ## Provenance and authentication considerations As an active, in-production automotive-grade part from TI, the TCAN1042DRBRQ1 is widely available through authorized distribution. The date-code laser etch on the 8-VSON package is a consistent, clean TI font — any lot with mismatched or sanded markings should raise a red flag. When sourcing through independent channels, the wettable flank package makes X-ray inspection straightforward: the exposed pad and side-wettable terminations show a clear, uniform solder fillet on genuine parts. Counterfeit risk on this part is low given the active status and volume, but the usual checks — date-code consistency across a reel, package marking alignment, and electrical parametric verification — still apply before committing a production run.","metaTitle":"TI TCAN1042DRBRQ1 CAN FD Transceiver, 5 Mbps, AEC-Q100","metaDescription":"Texas Instruments TCAN1042DRBRQ1 CAN FD transceiver, 5 Mbps data rate, AEC-Q100 qualified, -55°C to 125°C range, 8-VSON package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Interface & Transceivers"],"specifications":{"Mfr":"Texas Instruments","Type":"Transceiver","Duplex":"-","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Protocol":"CANbus","Data Rate":"5Mbps","Mounting Type":"Surface Mount, Wettable Flank","Package / Case":"8-VDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Voltage - Supply":"4.5V ~ 5.5V","Base Product Number":"TCAN1042","Operating Temperature":"-55°C~125°C","Supplier Device Package":"8-VSON (3x3)","Number of Drivers/Receivers":"1/1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3a364d689f0172292325d2d55ebef86f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TCAN1042DRBRQ1/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TCAN1042DRBRQ1 and TCAN1042DRBR?","answer":"The TCAN1042DRBRQ1 and TCAN1042DRBR share the same base CAN FD transceiver die and 5 Mbps data rate.
