ISO7710DW Digital Isolator Equivalent & Substitute Parts

Part Overview

The ISO7710DW is a general purpose digital isolator manufactured by Texas Instruments, designed for galvanic isolation applications requiring 5000Vrms isolation voltage. This single-channel, unidirectional isolator operates at 100Mbps data rate with 85kV/µs common mode transient immunity and is packaged in 16-SOIC surface mount configuration.

The ISO7710DW carries Last Time Buy status, indicating discontinued production. Equivalent and substitute parts are available to support ongoing design requirements and procurement needs. Substitute parts maintain identical electrical performance and mechanical compatibility while offering different packaging formats or active product status.

Substitute Part Grouping Explanation

Substitute parts for the ISO7710DW are classified based on packaging format while maintaining identical electrical specifications and mechanical compatibility. Substitution eligibility is determined by the following criteria:

Mandatory Matching Parameters:

• Isolation Voltage: 5000Vrms
• Number of Channels: 1
• Channel Type: Unidirectional
• Data Rate: 100Mbps
• Common Mode Transient Immunity: 85kV/µs (minimum)
• Propagation Delay: 16ns maximum (both directions)
• Pulse Width Distortion: 4.9ns maximum
• Supply Voltage Range: 2.25V ~ 5.5V
• Operating Temperature: -55°C ~ 125°C
• Package / Case: 16-SOIC (0.295", 7.50mm Width)
• Technology: Capacitive Coupling
• RoHS Status: ROHS3 Compliant

Variable Parameters (Substitution Basis):

• Packaging Format: Tube vs. Tape & Reel (TR)
• Product Status: Last Time Buy vs. Active

All substitute parts maintain 100% electrical and mechanical compatibility with the ISO7710DW within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

ISO7710DWR (Tape & Reel Format): Select this substitute when procurement specifications require Tape & Reel packaging for automated assembly processes. This part carries Active product status, ensuring long-term availability and supply chain continuity. Electrical and mechanical specifications are identical to ISO7710DW. Inventory availability is 9320 units.

ISO7710FDW (Tube Format): Select this substitute when tube packaging is required and Active product status is preferred over Last Time Buy designation. This part maintains identical electrical performance and 16-SOIC package compatibility with ISO7710DW. Inventory availability is 2914 units.

ISO7710DW (Original Part): This part remains available with 3088 units in stock despite Last Time Buy status. Selection is appropriate for existing designs with established supply agreements or when specific procurement documentation references this exact part number.

All three parts are ROHS3 compliant and REACH unaffected, meeting regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can ISO7710DWR be used as a direct replacement for ISO7710DW in PCB assembly?

A: Yes. ISO7710DWR is electrically and mechanically identical to ISO7710DW. The only difference is packaging format: ISO7710DWR uses Tape & Reel (TR) format while ISO7710DW uses Tube format. Both mount identically in 16-SOIC footprints. Tape & Reel format is optimized for high-volume automated assembly, while Tube format is suitable for lower-volume or manual assembly processes.

Q: What is the difference between ISO7710DW and ISO7710FDW?

A: Both parts are identical in electrical specifications and package type (16-SOIC). The difference lies in product status: ISO7710DW is Last Time Buy (discontinued production), while ISO7710FDW is Active (ongoing production). ISO7710FDW is recommended for new designs requiring long-term component availability.

Q: Are all three parts pin-compatible?

A: Yes. All three parts (ISO7710DW, ISO7710DWR, ISO7710FDW) use the same 16-SOIC package with identical pin assignments. They are fully interchangeable at the PCB level without layout modifications.

Q: Which substitute should I select for high-volume production?

A: ISO7710DWR (Tape & Reel format) is optimized for high-volume automated assembly. This format reduces handling time and improves pick-and-place efficiency compared to Tube packaging.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry identical Moisture Sensitivity Level (MSL) rating of 2 (1 Year). They meet the same regulatory and environmental requirements.

Q: What is the isolation voltage specification, and does it apply to all substitutes?

A: All parts provide 5000Vrms galvanic isolation. This specification is identical across ISO7710DW, ISO7710DWR, and ISO7710FDW, ensuring equivalent isolation performance in all applications.

Q: Can I mix packaging formats in the same production run?

A: Yes. Since all parts are electrically and mechanically identical, mixing Tube (ISO7710DW, ISO7710FDW) and Tape & Reel (ISO7710DWR) formats is technically feasible. However, assembly process optimization typically favors consistent packaging format within a single production batch.
