ISO7720DWR Digital Isolator Equivalent & Substitute Parts

Part Overview

The ISO7720DWR is a general purpose digital isolator manufactured by Texas Instruments, featuring 5000Vrms isolation voltage with 2 channels and 100Mbps data rate in a 16-SOIC surface mount package. The device is Active product status and ROHS3 compliant. Alternative part numbers are necessary when specific packaging formats, channel configurations, or inventory availability require substitution while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISO7720DWR is determined by the following critical parameters:

Channel Configuration: The ISO7720DWR operates with 2 channels (Inputs - Side 1/Side 2: 2/0). The ISO7710DWR and ISO7710FDWR variants operate with 1 channel (Inputs - Side 1/Side 2: 1/0) and are functionally equivalent for single-channel isolation applications.

Packaging Format: The ISO7720DWR is supplied in Tape & Reel (TR) format. The ISO7720FDWR is supplied in Cut Tape (CT) & Digi-Reel® format. Both maintain identical electrical specifications and the same 16-SOIC package footprint.

Electrical Equivalence: All substitute parts maintain identical isolation voltage (5000Vrms), CMTI (85kV/µs), data rate (100Mbps), propagation delay (16ns max), supply voltage range (2.25V ~ 5.5V), and operating temperature range (-55°C ~ 125°C).

Compliance & Certifications: All parts are Active status, ROHS3 compliant, REACH unaffected, and carry identical MSL rating (2, 1 Year).

Parameter Comparison

Engineering Selection Recommendations

ISO7720FDWR: Select this part when the application requires 2-channel isolation with Cut Tape or Digi-Reel® packaging format. Electrical performance is identical to ISO7720DWR. All compliance certifications (ROHS3, REACH unaffected) are maintained.

ISO7710DWR or ISO7710FDWR: Select either variant when the application requires only 1-channel isolation. Both maintain identical electrical specifications to the main part. ISO7710DWR is supplied in Tape & Reel format; ISO7710FDWR is supplied in Cut Tape & Digi-Reel® format. Channel reduction does not affect isolation voltage, CMTI, data rate, or timing characteristics.

All substitute parts are Active status products with equivalent reliability and compliance profiles.

Frequently Asked Questions (FAQ)

Q: Can ISO7710DWR replace ISO7720DWR in a 2-channel isolation application? A: No. The ISO7710DWR provides only 1 channel of isolation. It is suitable only for single-channel isolation requirements. For 2-channel applications, use ISO7720DWR or ISO7720FDWR.

Q: What is the difference between ISO7720DWR and ISO7720FDWR? A: Both parts are electrically identical 2-channel digital isolators with 5000Vrms isolation. The difference is packaging format: ISO7720DWR is supplied in Tape & Reel (TR); ISO7720FDWR is supplied in Cut Tape (CT) & Digi-Reel®. The 16-SOIC package footprint is identical.

Q: Are all substitute parts ROHS3 compliant? A: Yes. ISO7710DWR, ISO7710FDWR, and ISO7720FDWR are all ROHS3 compliant with identical MSL rating (2, 1 Year) to the main part.

Q: Can I use ISO7710FDWR in place of ISO7710DWR? A: Yes, for single-channel applications. Both parts are electrically equivalent. The difference is packaging format: ISO7710DWR is Tape & Reel; ISO7710FDWR is Cut Tape & Digi-Reel®. The 16-SOIC package footprint is identical.

Q: Do all substitute parts operate at the same supply voltage range? A: Yes. All parts operate at 2.25V ~ 5.5V supply voltage with identical propagation delay, CMTI, and data rate specifications.
