Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISO7820DWR are identified based on the following critical parameters that determine functional equivalence:

Isolation Voltage: 5700Vrms minimum requirement Common Mode Transient Immunity: 100kV/µs minimum Data Rate: 100Mbps minimum Supply Voltage Range: 2.25V ~ 5.5V compatibility Package Type: 16-SOIC form factor Technology: Capacitive coupling isolation method Product Status: Active manufacturing status Compliance: ROHS3 compliance requirement

The ISO7810DWR qualifies as a parametric equivalent within this product category. While the channel configuration differs (1 channel versus 2 channels), all electrical performance parameters, isolation specifications, timing characteristics, supply voltage range, operating temperature range, package form factor, and compliance certifications remain identical or equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the ISO7820DWR and ISO7810DWR maintain active product status with full manufacturing support from Texas Instruments. Both components carry ROHS3 compliance certification and REACH unaffected status, meeting current regulatory requirements for industrial and commercial applications.

Selection between these parts depends on circuit requirements for channel count. The ISO7820DWR provides 2-channel isolation in a single package, while the ISO7810DWR provides 1-channel isolation. All electrical performance metrics, timing characteristics, isolation voltage ratings, and environmental operating ranges are identical between the two parts.

Both components are available in 16-SOIC surface mount packaging with identical pinout compatibility within their respective channel configurations. Supply voltage requirements, common mode transient immunity specifications, and data rate capabilities are equivalent across both parts.

Frequently Asked Questions (FAQ)

Q: Can ISO7810DWR replace ISO7820DWR in all applications?

A: The ISO7810DWR can replace the ISO7820DWR only in applications requiring single-channel isolation. All electrical performance parameters, isolation voltage, timing characteristics, and environmental specifications are identical. Circuit design must accommodate the reduced channel count.

Q: Are the package dimensions identical between these parts?

A: Both parts use 16-SOIC (0.295", 7.50mm Width) surface mount packaging. Physical dimensions and PCB footprints are identical, allowing direct board-level substitution where channel requirements permit.

Q: What is the isolation voltage rating for both parts?

A: Both ISO7820DWR and ISO7810DWR provide 5700Vrms isolation voltage with 100kV/µs common mode transient immunity, meeting high-voltage isolation requirements in industrial control and power management applications.

Q: Are there supply voltage compatibility differences?

A: Both parts operate across the identical supply voltage range of 2.25V to 5.5V. No supply voltage adjustments are required when substituting between these components.

Q: What is the data rate specification for these isolators?

A: Both the ISO7820DWR and ISO7810DWR support 100Mbps data rate with identical propagation delay characteristics of 16ns maximum for both rising and falling edges.

Q: Do both parts meet current compliance standards?

A: Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use in regulated industries.
