ISO1050DUB Equivalent & Substitute Parts

Part Overview

The ISO1050DUB is a 1/1 transceiver for isolated half CANbus applications in an 8-SOP surface mount package. This part is designated as Last Time Buy, indicating end-of-life status. Identifying equivalent substitute parts is essential for design continuity, inventory management, and long-term product support when the original part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISO1050DUB is determined by strict equivalence across the following critical parameters:

• Functional Type: Transceiver, Isolated CANbus
• Channel Configuration: 1/1 (one driver, one receiver)
• Duplex Mode: Half duplex operation
• Data Rate: 1 Mbps maximum
• Supply Voltage Range: 3V ~ 5.5V
• Receiver Hysteresis: 150 mV
• Package: 8-SOP surface mount with gull wing leads
• Electrical Characteristics: Operating temperature range -55°C ~ 105°C
• Compliance: ROHS3 Compliant, REACH Unaffected

Only parts matching all these parameters across electrical function, pin configuration, and physical packaging qualify as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The ISO1050DUBR is the direct substitute for the ISO1050DUB. Both parts are manufactured by Texas Instruments and maintain identical electrical specifications, functional characteristics, and physical packaging. The primary distinction is product status: the ISO1050DUB is Last Time Buy, while the ISO1050DUBR is Active.

For new designs or ongoing production requiring CANbus isolation transceivers, the ISO1050DUBR should be selected. This part offers the same performance envelope with assured long-term availability. Both parts carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements.

The packaging difference (Tube versus Cut Tape & Digi-Reel) does not affect electrical or mechanical compatibility and reflects only the distribution format.

Frequently Asked Questions (FAQ)

Q: Can ISO1050DUBR be used as a direct replacement for ISO1050DUB in existing designs?

A: Yes. The ISO1050DUBR is electrically and mechanically identical to the ISO1050DUB. All electrical parameters, pin assignments, and package dimensions are equivalent. No circuit modifications are required.

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

A: Tube and Cut Tape are distribution formats only. They do not affect the component's electrical performance or physical characteristics. Tube packaging is typically used for lower-volume orders, while Cut Tape and Digi-Reel are standard for production quantities.

Q: Why is the ISO1050DUB marked as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer is discontinuing this part number. The ISO1050DUBR remains in active production and is the recommended long-term alternative.

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

A: No. Both parts carry identical ROHS3 compliance and REACH Unaffected status. Moisture sensitivity level and all regulatory classifications are the same.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts use the 8-SOP package with gull wing leads and are compatible with standard surface mount assembly processes. No design changes to PCB layout or assembly procedures are necessary.
