ISO7710DWR Digital Isolator Equivalent & Substitute Parts

Part Overview

The ISO7710DWR is a general purpose digital isolator manufactured by Texas Instruments, designed for applications requiring galvanic isolation with high common mode transient immunity. This single-channel capacitive coupling isolator operates at 5000Vrms isolation voltage and supports data rates up to 100Mbps. The device is currently in active production status and widely used in industrial control, power management, and communication interface applications where electrical isolation is critical.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when supply chain constraints occur, or when design flexibility is required for procurement optimization while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISO7710DWR is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Isolation voltage: 5000Vrms
• Common mode transient immunity: 85kV/µs minimum
• Data rate: 100Mbps
• Supply voltage range: 2.25V ~ 5.5V
• Operating temperature range: -55°C ~ 125°C
• Channel configuration: 1 channel, unidirectional
• Propagation delay specifications: 16ns maximum (tpLH and tpHL)
• Pulse width distortion: 4.9ns maximum

Mechanical Equivalence Criteria:

• Package type: 16-SOIC (0.295", 7.50mm Width)
• Mounting type: Surface Mount
• Supplier device package: 16-SOIC

Compliance Equivalence Criteria:

• RoHS3 compliance
• Moisture sensitivity level: 2 (1 Year)
• Product status: Active

The ISO7710FDWR meets all these criteria and is therefore a direct parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the ISO7710DWR and ISO7710FDWR are active production devices from Texas Instruments with identical electrical and mechanical specifications. Selection between these parts is based on availability and procurement requirements rather than technical differentiation.

The ISO7710DWR currently maintains higher inventory levels (9320 pieces) compared to the ISO7710FDWR (1633 pieces). Both devices carry ROHS3 compliance certification and REACH unaffected status, making them suitable for regulated applications in industrial, automotive, and consumer electronics markets.

For applications where the primary part number becomes unavailable, the ISO7710FDWR provides direct substitution without design modification, PCB layout changes, or firmware updates. The identical package footprint, pin configuration, and electrical performance ensure drop-in compatibility.

Frequently Asked Questions (FAQ)

Q: Can ISO7710FDWR replace ISO7710DWR in existing designs?

A: Yes. The ISO7710FDWR is a direct parametric equivalent with identical electrical specifications, package type, and pin configuration. No design changes are required for substitution.

Q: Are there differences in isolation voltage or data rate between these parts?

A: No. Both parts operate at 5000Vrms isolation voltage with 100Mbps data rate capability and 85kV/µs common mode transient immunity.

Q: Do both parts use the same package footprint?

A: Yes. Both the ISO7710DWR and ISO7710FDWR use the 16-SOIC (0.295", 7.50mm Width) surface mount package. PCB layouts are fully compatible without modification.

Q: What is the significance of the different part number suffixes (DWR vs FDWR)?

A: The suffix variation indicates different manufacturing batches or internal product line designations within Texas Instruments. Both parts meet identical electrical and mechanical specifications and are functionally interchangeable.

Q: Are both parts RoHS compliant?

A: Yes. Both the ISO7710DWR and ISO7710FDWR are ROHS3 compliant with MSL 2 (1 Year) moisture sensitivity rating.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection should be based on current availability and supply chain lead times. Both parts carry active production status and identical performance characteristics.
