IL 717T-3E Digital Isolator Equivalent & Substitute Parts

Part Overview

The IL 717T-3E is a general purpose digital isolator manufactured by NVE Corp/Isolation Products, part of the IsoLoop® series. This component provides galvanic isolation for digital signals using Giant Magnetoresistive (GMR) technology. The device features 4 channels with 2500Vrms isolation rating, supporting data rates up to 110Mbps with high common mode transient immunity of 100kV/µs. The IL 717T-3E is classified as an active product with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance, isolation voltage, channel configuration, and package specifications align with the main part, enabling direct replacement in circuit designs where the specific performance characteristics are met.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IL 717T-3E is determined by the following critical parameters:

Mandatory Matching Criteria:

• Isolation voltage rating of 2500Vrms
• 4-channel configuration with 3 inputs and 1 output (unidirectional)
• 16-SOIC package format (0.154", 3.90mm Width)
• Data rate of 110Mbps or higher
• Supply voltage range compatibility (3V to 5.5V)
• Propagation delay specifications of 15ns or better
• Pulse width distortion of 3ns or lower

Allowable Parameter Variations:

• Common Mode Transient Immunity: Substitute parts may have lower CMTI values than the main part (100kV/µs) while maintaining functional isolation performance
• Operating temperature range: Substitute parts may have extended lower temperature limits
• Inventory availability and packaging format (Tube)

The HCPL-092J-000E meets all mandatory matching criteria and qualifies as a direct substitute based on electrical and mechanical compatibility.

Engineering Selection Recommendations

IL 717T-3E (NVE Corp/Isolation Products):

• Primary selection for applications requiring 100kV/µs common mode transient immunity
• Active product status with established supply chain
• Operating temperature range -40°C to 125°C suitable for standard industrial applications
• RoHS3 compliant and REACH unaffected

HCPL-092J-000E (Broadcom Limited):

• Direct substitute where 15kV/µs common mode transient immunity is acceptable
• Extended operating temperature range (-55°C to 125°C) for low-temperature environments
• Active product status with high inventory availability (750,400 pcs)
• RoHS3 compliant and REACH unaffected
• Identical electrical performance in propagation delay, pulse width distortion, and data rate specifications

Both parts maintain full compliance with RoHS3 and REACH regulations. Selection between these parts depends on application-specific requirements for common mode transient immunity and operating temperature range. The 16-SOIC package format ensures mechanical compatibility in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-092J-000E replace the IL 717T-3E in all applications?

A: The HCPL-092J-000E is electrically compatible for applications where the common mode transient immunity requirement is 15kV/µs or lower. If your circuit design requires 100kV/µs CMTI performance, the IL 717T-3E is the appropriate selection. Both parts share identical isolation voltage, channel configuration, data rate, propagation delay, and package specifications.

Q: What is the significance of the different CMTI values?

A: Common Mode Transient Immunity (CMTI) specifies the maximum rate of change of common mode voltage that the isolator can withstand without causing errors. The IL 717T-3E supports 100kV/µs while the HCPL-092J-000E supports 15kV/µs. Applications with high-speed switching or high dV/dt environments may require the higher CMTI rating of the IL 717T-3E.

Q: Are the 16-SOIC packages identical between these parts?

A: Yes. Both the IL 717T-3E and HCPL-092J-000E use the 16-SOIC (0.154", 3.90mm Width) package format. Pin-to-pin compatibility and PCB footprint requirements are identical, enabling direct board-level substitution without layout modifications.

Q: What is the operating temperature difference between these parts?

A: The IL 717T-3E operates from -40°C to 125°C, while the HCPL-092J-000E operates from -55°C to 125°C. The HCPL-092J-000E provides extended low-temperature capability, making it suitable for applications requiring operation in cold environments below -40°C.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the IL 717T-3E and HCPL-092J-000E are RoHS3 compliant, REACH unaffected, classified as EAR99, and carry MSL 1 (unlimited) moisture sensitivity ratings. Regulatory and environmental compliance is equivalent between the two parts.

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

A: Both parts support 110Mbps (IL 717T-3E) and 110MBd (HCPL-092J-000E) data rates. These specifications are functionally equivalent for digital isolation applications. Propagation delay is 15ns for both tpLH and tpHL in both parts.

Q: How do I determine which part to use in my design?

A: Evaluate your application against these criteria: (1) Required common mode transient immunity—if 100kV/µs is necessary, use IL 717T-3E; if 15kV/µs is sufficient, either part is acceptable; (2) Operating temperature range—if operation below -40°C is required, use HCPL-092J-000E; (3) Supply voltage (both support 3V to 5.5V); (4) Isolation voltage requirement (both provide 2500Vrms). All other electrical and mechanical specifications are identical.
