ISO1430DWR Equivalent & Substitute Parts

Part Overview

The ISO1430DWR is an isolated half-duplex RS422/RS485 transceiver manufactured by Texas Instruments, classified as an Interface integrated circuit. This component functions as a 1/1 transceiver with integrated isolation, designed for industrial communication applications requiring galvanic isolation between logic and bus domains. The part is currently in active production status with 1872 units available in new original inventory. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and compliance certifications are maintained across alternative packaging or distribution formats.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISO1430DWR is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Protocol support: RS422 and RS485
• Driver/Receiver configuration: 1/1 topology
• Duplex mode: Half-duplex operation
• Data rate: 12 Mbps minimum
• Receiver hysteresis: 30 mV
• Supply voltage ranges: 1.71V ~ 1.89V, 2.25V ~ 5.5V, 3V ~ 5.5V
• Operating temperature: -40°C ~ 125°C

Mechanical Compatibility Requirements:

• Package type: 16-SOIC (0.295", 7.50mm Width)
• Mounting type: Surface Mount
• Base product number: ISO1430

Compliance Requirements:

• RoHS3 compliance
• MSL rating: 2 (1 Year)
• REACH unaffected status
• ECCN: EAR99

The ISO1430BDWR meets all substitution criteria as a parametric equivalent with identical electrical specifications and mechanical form factor, differing only in packaging format (Cut Tape and Digi-Reel distribution).

Parameter Comparison

Engineering Selection Recommendations

Both the ISO1430DWR and ISO1430BDWR are active production components from Texas Instruments with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on procurement and supply chain requirements rather than functional or electrical differences.

ISO1430DWR is appropriate for applications where standard packaging and distribution formats are specified or preferred.

ISO1430BDWR is appropriate for high-volume production environments or applications where Cut Tape and Digi-Reel packaging formats provide supply chain advantages. This variant maintains identical electrical performance and mechanical compatibility while offering higher inventory availability (4300 units versus 1872 units).

Both parts satisfy identical design requirements for isolated half-duplex RS422/RS485 transceiver applications operating across the specified voltage and temperature ranges. Component selection should be based on packaging format compatibility with assembly equipment and procurement logistics.

Frequently Asked Questions (FAQ)

Q: Can ISO1430BDWR be used as a direct replacement for ISO1430DWR in production?

A: Yes. The ISO1430BDWR is a parametric equivalent with identical electrical specifications, data rates, voltage ranges, temperature ratings, and 16-SOIC package dimensions. The only difference is the packaging format (Cut Tape and Digi-Reel distribution). Both parts are suitable for identical PCB assembly processes and circuit applications.

Q: What is the difference between the packaging formats?

A: ISO1430DWR uses standard packaging, while ISO1430BDWR is supplied in Cut Tape (CT) and Digi-Reel formats. These are distribution and handling formats that do not affect the electrical or mechanical properties of the component itself. Selection depends on compatibility with your assembly equipment and procurement preferences.

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

A: No. Both parts carry identical ROHS3 compliance, REACH unaffected status, ECCN EAR99 classification, and MSL 2 (1 Year) moisture sensitivity ratings. They meet the same regulatory and environmental standards.

Q: What are the critical parameters that must match for substitution?

A: The following parameters must be identical for substitution: RS422/RS485 protocol support, 1/1 driver/receiver configuration, half-duplex operation, 12 Mbps data rate, 30 mV receiver hysteresis, supply voltage ranges (1.71V ~ 1.89V, 2.25V ~ 5.5V, 3V ~ 5.5V), operating temperature range (-40°C ~ 125°C), and 16-SOIC package form factor.

Q: Can these parts be used in applications requiring full-duplex communication?

A: No. Both ISO1430DWR and ISO1430BDWR are half-duplex transceivers. Applications requiring simultaneous bidirectional communication require full-duplex transceiver variants.

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

A: Both parts support a maximum data rate of 12 Mbps for RS422 and RS485 communication protocols.

Q: Are these parts suitable for isolated applications?

A: Yes. Both ISO1430DWR and ISO1430BDWR include integrated galvanic isolation between the logic side and the RS422/RS485 bus side, making them suitable for applications requiring electrical isolation between domains.
