Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISO7720D digital isolator are selected strictly based on the following key parameters: technology (capacitive coupling), category (digital isolator), isolation voltage (3000Vrms), data rate (100Mbps), common mode transient immunity (≥85kV/μs), electrical channel configuration, package type (8-SOIC), supply voltage range (2.25V ~ 5.5V), operating temperature (-55°C ~ 125°C), mounting type (surface mount), and compliance (RoHS, REACH). Groupings are determined by exact electrical and mechanical matching within these parameters.

Parameter Comparison

Engineering Selection Recommendations

The ISO7720D digital isolator is in "Last Time Buy" status. Selection of substitute parts such as ISO7720DR and ISO7720FD is supported by active product status, matching electrical characteristics, mechanical compatibility (8-SOIC surface mount package), and certification (ROHS3, REACH). ISO7710FD presents a parametric equivalent with single-channel functionality and matching electrical and regulatory parameters.

Frequently Asked Questions (FAQ)

Q1: What key parameters must match when selecting a substitute for ISO7720D?
A1: Substitution requires matching technology, number of channels, channel type, voltage isolation, supply voltage, package type, data rate, transient immunity, and regulatory certifications.

Q2: Are ISO7720DR and ISO7720FD direct substitutes for ISO7720D?
A2: ISO7720DR and ISO7720FD are direct substitutes with identical electrical specifications and package compatibility.

Q3: Is the package and mounting type consistent across substitutes?
A3: All substitutes utilize the 8-SOIC (0.154", 3.90mm Width) surface mount package, ensuring mechanical compatibility.

Q4: What consideration applies to ISO7710FD as a substitute?
A4: ISO7710FD matches all parameters except channel count, offering a single channel in the same package with equivalent electrical and compliance characteristics.

Q5: Are all listed substitute parts compliant with ROHS and REACH?
A5: All substitutes are ROHS3 compliant and REACH unaffected, aligning with standard environmental and safety requirements for electronic components.
