ISO1042DWVR Equivalent & Substitute Parts

Part Overview

The ISO1042DWVR is a full-duplex CANbus transceiver manufactured by Texas Instruments, designed for automotive and industrial communication applications. This 8-SOIC surface-mount device operates across dual voltage ranges (1.71V–1.89V and 2.25V–5.5V) and supports data rates up to 5 Mbps with a receiver hysteresis of 120 mV. The part is currently in active production status with ROHS3 compliance and REACH unaffected classification. Equivalent substitute parts are identified based on matching electrical specifications, mechanical packaging, and functional performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISO1042DWVR are identified through parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must match identically:

• Protocol: CANbus full-duplex communication
• Driver/Receiver Configuration: 1/1 topology
• Data Rate: 5 Mbps maximum
• Receiver Hysteresis: 120 mV
• Supply Voltage Ranges: 1.71V–1.89V and 2.25V–5.5V
• Operating Temperature Range: −40°C to +125°C
• Package Type: 8-SOIC with 7.50mm width
• Surface Mount Mounting Type
• RoHS3 and REACH compliance status

The ISO1042BDWVR meets all these criteria and is classified as a parametric equivalent. Both parts share identical functional specifications, electrical performance characteristics, and physical packaging dimensions, enabling direct substitution in circuit designs without modification to PCB layouts or firmware implementations.

Parameter Comparison

Engineering Selection Recommendations

Both the ISO1042DWVR and ISO1042BDWVR are active production parts from Texas Instruments with identical electrical specifications and mechanical packaging. Selection between these parts should be based on inventory availability and supply chain considerations. The ISO1042BDWVR currently maintains higher inventory levels (61,419 pcs) compared to the ISO1042DWVR (17,954 pcs), making it suitable for high-volume production requirements where lead time and stock availability are critical factors.

Both parts carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for automotive and industrial applications. The 8-SOIC package format and surface-mount configuration are identical, eliminating any PCB redesign requirements. No firmware or circuit modifications are necessary when substituting between these parts.
