Texas Instruments TCAN1042HGDR
TCAN1042HGDR variants from Texas Instruments
TCAN1042HGDR Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
Key Features
- Footprint / package: 8-VDFN Exposed PadSingle package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 3 distinct suffix patternsExamples: Q1, BRQ1, BTQ1. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Microcontrollers — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained
Ordering Variants
Compare 3 TCAN1042HGDR part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Package Type | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|---|
| TCAN1042HGDRQ1 | Automotive 70-V bus-fault-protected CAN transceiver with 5-Mbps flexible data-rate 8-SOIC -55 to 125 | - | Texas Instruments | Active | Compliant | In Stock | |
| TCAN1042HGDRBRQ1 | Package: 8-VDFN Exposed Pad | Mounting Type: Surface Mount, Wettable Flank | Supply Voltage: 4.5V ~ 5.5V | Data Rate: 5Mbps | Operating Temperature: -55°C ~ 125°C | 8-VDFN Exposed Pad | Texas Instruments | Active | Compliant | In Stock | |

How to Choose the Right TCAN1042HGDR Microcontrollers
Match the footprint first
Packages here: 8-VDFN Exposed Pad. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For TCAN1042HGDR, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "TCAN1042HGDR" — include the full suffix (e.g. Q1, BRQ1, BTQ1). RFQ with reel/tube preference and required date code.
