ISO1042BDWVR Equivalent & Substitute Parts

Part Overview

The ISO1042BDWVR is a full-duplex CANbus transceiver manufactured by Texas Instruments, designed for interface applications requiring reliable CAN communication. This 1/1 transceiver is packaged in an 8-SOIC surface-mount configuration and operates across dual voltage supply ranges (1.71V–1.89V and 2.25V–5.5V). The part maintains Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when identical electrical specifications, mechanical packaging, and compliance certifications are maintained across the product line.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISO1042BDWVR is limited to parts maintaining identical electrical and mechanical specifications. The critical parameters determining substitutability are: CANbus protocol compliance, 1/1 driver/receiver configuration, full-duplex operation, 5 Mbps data rate, 120 mV receiver hysteresis, dual voltage supply ranges (1.71V–1.89V and 2.25V–5.5V), −40°C to +125°C operating temperature range, and 8-SOIC surface-mount packaging. The ISO1042DWVR meets all these requirements and is classified as a parametric equivalent within the Texas Instruments ISO1042 base product family.

Parameter Comparison

Engineering Selection Recommendations
