ISO1450DWR Equivalent & Substitute Parts

Part Overview

The ISO1450DWR is an isolated half-duplex transceiver manufactured by Texas Instruments, designed for RS422 and RS485 communication protocols. This surface-mount interface IC integrates a single driver and receiver pair in a 16-SOIC package, operating across multiple supply voltage ranges with a maximum data rate of 50 Mbps. The device is classified as Active product status and maintains full compliance with ROHS3 and REACH standards. Substitute parts are identified to provide alternative sourcing options when the primary part number becomes unavailable or when packaging preferences differ.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISO1450DWR are identified based on strict electrical and mechanical parameter equivalence. The substitution logic is based on the following critical parameters:

Electrical Parameters:

• Protocol compatibility: RS422 and RS485
• Driver/Receiver configuration: 1/1 (single driver, single receiver)
• Duplex mode: Half-duplex operation
• Receiver hysteresis: 30 mV
• Data rate: 50 Mbps maximum
• Supply voltage ranges: 1.71V ~ 1.89V, 2.25V ~ 5.5V, 3V ~ 5.5V
• Operating temperature range: -40°C ~ 125°C

Mechanical Parameters:

• Package type: 16-SOIC
• Package dimensions: 0.295" width, 7.50mm width
• Mounting type: Surface Mount
• Supplier device package: 16-SOIC

Compliance Parameters:

• RoHS3 Compliance
• REACH Unaffected status
• Moisture Sensitivity Level: 2 (1 Year)

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both the ISO1450DWR and ISO1450BDWR are Active product status devices manufactured by Texas Instruments with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply chain requirements rather than functional differences.

ISO1450DWR is suitable for applications requiring standard packaging formats with current inventory of 6200 pieces available.

ISO1450BDWR is suitable for applications requiring Cut Tape (CT) or Digi-Reel® packaging formats, with current inventory of 8100 pieces available.

Both parts maintain full ROHS3 compliance and REACH Unaffected status, meeting regulatory requirements for industrial and commercial applications. The identical electrical specifications, including 50 Mbps data rate, 30 mV receiver hysteresis, and multi-range supply voltage support, ensure functional interchangeability in RS422 and RS485 half-duplex communication circuits.

Frequently Asked Questions (FAQ)

Q: Are ISO1450DWR and ISO1450BDWR electrically identical?

A: Yes. Both parts share identical electrical specifications including protocol support (RS422/RS485), driver/receiver configuration (1/1), duplex mode (half), data rate (50 Mbps), receiver hysteresis (30 mV), supply voltage ranges (1.71V ~ 1.89V, 2.25V ~ 5.5V, 3V ~ 5.5V), and operating temperature range (-40°C ~ 125°C).

Q: What is the difference between ISO1450DWR and ISO1450BDWR?

A: The primary difference is packaging format. ISO1450DWR uses standard packaging, while ISO1450BDWR is supplied in Cut Tape (CT) and Digi-Reel® formats. Both use identical 16-SOIC packages with 0.295" width and 7.50mm dimensions.

Q: Can I substitute ISO1450BDWR for ISO1450DWR in my circuit design?

A: Yes. The parts are parametric equivalents with identical electrical and mechanical specifications. Substitution is valid for all RS422 and RS485 half-duplex communication applications operating within the specified voltage and temperature ranges.

Q: Are both parts RoHS compliant?

A: Yes. Both ISO1450DWR and ISO1450BDWR are ROHS3 Compliant and REACH Unaffected, meeting regulatory requirements for industrial and commercial applications.

Q: What is the Moisture Sensitivity Level for these parts?

A: Both parts have Moisture Sensitivity Level (MSL) 2 with a 1-year shelf life rating, requiring standard moisture control handling during storage and assembly.

Q: Which part should I select based on my supply chain requirements?

A: Selection depends on packaging preference and inventory availability. ISO1450DWR is available in standard packaging with 6200 pieces in stock. ISO1450BDWR is available in Cut Tape (CT) and Digi-Reel® formats with 8100 pieces in stock. Both are Active status products suitable for immediate procurement.
