IL 711T-2E Digital Isolator Equivalent & Substitute Parts

Part Overview

The IL 711T-2E is a General Purpose Digital Isolator manufactured by NVE Corp/Isolation Products, part of the IsoLoop® series. This component provides galvanic isolation using Giant Magnetoresistive (GMR) technology with a 2500Vrms isolation rating across 2 channels. The device is Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when design requirements permit reduction in channel count or when inventory constraints necessitate alternative sourcing while maintaining critical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the IL 711T-2E is limited to the IL 710T-2E based on the following criteria:

Substitution Logic: The IL 710T-2E qualifies as a parametric equivalent substitute when the application requires only single-channel isolation. Both devices share identical electrical performance in the following critical parameters:

• Isolation voltage: 2500Vrms
• Data rate: 110Mbps
• Common Mode Transient Immunity: 100kV/µs (minimum)
• Propagation delay: 15ns (maximum, both directions)
• Pulse width distortion: 3ns (maximum)
• Supply voltage range: 3V to 5.5V
• Operating temperature: -40°C to +125°C
• Package: 8-DIP (0.300", 7.62mm) through-hole
• Technology: GMR (Giant Magnetoresistive)
• Series: IsoLoop®
• Compliance: RoHS3, REACH Unaffected, MSL 1

Key Differentiator: The IL 710T-2E provides 1 channel (1 input on Side 1) versus the IL 711T-2E's 2 channels (2 inputs on Side 1). This reduction in channel count is the only functional difference. Substitution is valid only when the application circuit requires single-channel isolation.

Engineering Selection Recommendations

Primary Selection Criteria:

1. Channel Requirement: Select IL 711T-2E when the circuit design requires dual-channel isolation on a single device. Select IL 710T-2E only when single-channel isolation is sufficient for the application.

2. Product Status: Both IL 711T-2E and IL 710T-2E maintain Active product status with NVE Corp/Isolation Products, ensuring continued manufacturing support and availability.

3. Compliance Alignment: Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for industrial and commercial applications. MSL 1 rating (unlimited moisture sensitivity) applies to both devices.

4. Electrical Performance: When channel count permits substitution, the IL 710T-2E delivers identical electrical performance across all timing, isolation, and transient immunity specifications. No performance degradation occurs in single-channel applications.

5. Package Compatibility: Both devices use identical 8-DIP (0.300", 7.62mm) through-hole packaging. PCB layout and footprint remain unchanged during substitution, provided the application uses only one isolation channel.

6. Inventory Considerations: IL 710T-2E maintains 714 pieces in stock versus IL 711T-2E's 940 pieces. Substitution may be considered when IL 711T-2E availability is constrained and single-channel operation is acceptable.

Frequently Asked Questions (FAQ)

Q: Can IL 710T-2E replace IL 711T-2E in all applications?

A: No. IL 710T-2E is a valid substitute only when the circuit design requires single-channel isolation. Applications requiring two independent isolation channels must use IL 711T-2E or equivalent dual-channel devices.

Q: Are the electrical performance specifications identical between these parts?

A: Yes. Both devices share identical data rate (110Mbps), isolation voltage (2500Vrms), common mode transient immunity (100kV/µs minimum), propagation delay (15ns maximum), and pulse width distortion (3ns maximum) specifications.

Q: Do both parts use the same package footprint?

A: Yes. Both IL 711T-2E and IL 710T-2E use 8-DIP (0.300", 7.62mm) through-hole packaging. PCB footprints are identical, and no layout modifications are required for substitution.

Q: What is the key difference between these two parts?

A: The IL 711T-2E provides 2 isolation channels with 2 inputs on Side 1, while the IL 710T-2E provides 1 isolation channel with 1 input on Side 1. All other electrical and mechanical specifications are identical.

Q: Are both parts RoHS3 compliant?

A: Yes. Both IL 711T-2E and IL 710T-2E are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating and REACH unaffected status.

Q: What is the operating temperature range for both devices?

A: Both devices operate across -40°C to +125°C. Temperature performance is identical between IL 711T-2E and IL 710T-2E.

Q: Can I use IL 711T-2E as a substitute for IL 710T-2E?

A: Yes. IL 711T-2E can replace IL 710T-2E in any application. The additional channel in IL 711T-2E provides expanded functionality while maintaining full backward compatibility with single-channel designs.

Q: What supply voltage range do these isolators support?

A: Both devices operate with supply voltage from 3V to 5.5V. No voltage regulation differences exist between IL 711T-2E and IL 710T-2E.
