ISO1050DW Equivalent & Substitute Parts

Part Overview

The ISO1050DW is a 1/1 transceiver for isolated half CANbus applications, manufactured by Texas Instruments in a 16-SOIC surface mount package. This component is classified as Last Time Buy, indicating end-of-life status. Identifying equivalent substitute parts is essential for design continuity, long-term supply chain planning, and new production runs where the original part may become unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISO1050DW is determined by strict equivalence across the following critical parameters:

• Protocol and Functionality: CANbus half-duplex transceiver with 1/1 driver/receiver configuration
• Electrical Specifications: 1 Mbps data rate, 3V–5.5V supply voltage, 150 mV receiver hysteresis, -55°C to 105°C operating range
• Package Compatibility: 16-SOIC surface mount package with identical pinout and mechanical dimensions
• Compliance: ROHS3 compliance and MSL 2 rating maintained across substitutes
• Isolation Characteristics: Isolated transceiver topology

The ISO1050DWR qualifies as a direct substitute based on identical electrical performance, package specification, and compliance certifications. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The ISO1050DWR is the direct substitute for the ISO1050DW. Both parts are manufactured by Texas Instruments and maintain identical electrical specifications, thermal performance, and compliance certifications. The ISO1050DWR carries Active product status, ensuring continued availability and support, whereas the ISO1050DW is Last Time Buy.

Selection of the ISO1050DWR is appropriate for new designs and production runs requiring long-term supply assurance. The packaging format difference (Cut Tape & Digi-Reel versus Bulk) reflects standard distribution practices and does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ISO1050DWR be used as a direct replacement for the ISO1050DW in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The 16-SOIC package, pinout, electrical specifications, and operating parameters are equivalent. No circuit modifications are required.

Q: What is the difference between the Bulk and Cut Tape packaging formats?

A: Bulk packaging is typically used for high-volume orders and manual assembly processes. Cut Tape & Digi-Reel packaging is standard for automated pick-and-place assembly and lower-volume orders. The component itself is identical.

Q: Why is the ISO1050DW marked as Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing this specific packaging variant. The ISO1050DWR, with identical specifications but in Cut Tape & Digi-Reel format, remains in active production.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts maintain ROHS3 compliance, MSL 2 rating, and identical REACH and ECCN classifications for their respective product lines.

Q: What is the maximum data rate supported by these CANbus transceivers?

A: Both the ISO1050DW and ISO1050DWR support a maximum data rate of 1 Mbps, consistent with standard CANbus half-duplex operation.
