ISO7710FDWR Equivalent & Substitute Parts

Part Overview

The ISO7710FDWR 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 housed in a 16-SOIC surface mount package. The device is Active in product status and ROHS3 compliant, making it suitable for industrial and consumer applications requiring reliable isolation performance.

Substitute parts are identified when component availability is constrained or when design flexibility permits equivalent performance specifications across the same electrical and mechanical parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the ISO7710FDWR is determined by strict equivalence across the following critical parameters:

• Isolation voltage rating: 5000Vrms
• Channel configuration: 1 channel, unidirectional
• Data rate: 100Mbps
• Common mode transient immunity: 85kV/µs minimum
• Package type: 16-SOIC (0.295", 7.50mm Width)
• Supply voltage compatibility: 2.25V ~ 5.5V
• Operating temperature range: -55°C ~ 125°C
• Technology platform: Capacitive Coupling
• Compliance certifications: ROHS3, REACH Unaffected

The ISO7710DWR meets all specified electrical and mechanical parameters, establishing it as a parametric equivalent within the same product family and manufacturer ecosystem.

Parameter Comparison

Engineering Selection Recommendations

Both the ISO7710FDWR and ISO7710DWR are Active products from Texas Instruments with identical electrical specifications and mechanical packaging. Selection between these parts is based on availability and supply chain considerations rather than functional differentiation.

The ISO7710DWR currently maintains higher inventory levels (9320 Pcs) compared to the ISO7710FDWR (1633 Pcs), making it the preferred choice when supply continuity is a design consideration. Both devices carry ROHS3 compliance and REACH Unaffected status, ensuring regulatory alignment for industrial and consumer applications.

Frequently Asked Questions (FAQ)

Q: Can ISO7710DWR be used as a direct replacement for ISO7710FDWR in existing designs?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications, including isolation voltage, data rate, propagation delay, supply voltage range, operating temperature, and package configuration. No design modifications are required for substitution.

Q: What is the difference between ISO7710FDWR and ISO7710DWR?

A: The parts are functionally identical. The designation difference reflects packaging or manufacturing batch variations within the same product family. Both utilize capacitive coupling technology and meet identical performance criteria.

Q: Are there any compatibility concerns with the 16-SOIC package?

A: No. Both parts use the identical 16-SOIC (0.295", 7.50mm Width) package, ensuring footprint and pinout compatibility on PCB layouts. Moisture sensitivity level (MSL 2, 1 Year) is identical for both parts.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ISO7710FDWR and ISO7710DWR are ROHS3 compliant and REACH Unaffected, meeting equivalent regulatory requirements for industrial and consumer applications.

Q: What supply voltage range do these isolators support?

A: Both parts operate across 2.25V to 5.5V supply voltage range, providing flexibility for single-supply and dual-supply system designs.
