IL 716 Digital Isolator Equivalent & Substitute Parts

Part Overview

The IL 716 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 four channels. The IL 716 is classified as an active product and is suitable for applications requiring robust common-mode transient immunity and high-speed digital signal isolation in industrial and consumer electronics.

Substitute parts are identified when electrical performance parameters, mechanical compatibility, and functional specifications remain equivalent across different packaging configurations or compliance certifications.

Substitute Part Grouping Explanation

Substitution eligibility for the IL 716 is determined by strict equivalence across the following critical parameters:

Electrical Performance Criteria:

• Isolation voltage rating: 2500Vrms
• Number of isolated channels: 4
• Data rate: 110Mbps
• Common mode transient immunity: 100kV/µs minimum
• Propagation delay specifications: 15ns maximum (both rising and falling edges)
• Pulse width distortion: 3ns maximum
• Supply voltage range: 3V to 5.5V
• Operating temperature range: -40°C to 100°C

Mechanical Compatibility Criteria:

• Package type: 16-SOIC (0.295", 7.50mm Width)
• Mounting type: Surface Mount
• Pin configuration: 2 inputs per side, 2 outputs per side (unidirectional channels)

Functional Criteria:

• Technology: GMR-based isolation
• Type: General Purpose digital isolator
• Series: IsoLoop®

Substitute parts must match all electrical performance parameters, mechanical dimensions, and functional specifications. Variations in packaging format (such as tube versus tape-and-reel) or compliance certifications do not affect functional substitutability when all technical parameters remain identical.

Engineering Selection Recommendations

IL 716 (Base Part Number)

The IL 716 is suitable for applications where RoHS compliance is not a regulatory requirement. This variant maintains full electrical and mechanical equivalence with the IL 716E. Selection of this part is appropriate for legacy designs, non-regulated markets, or applications where RoHS3 compliance is not mandated.

IL 716E (Substitute Part Number)

The IL 716E is the ROHS3-compliant variant of the IL 716 and is recommended for new designs, regulated markets, and applications subject to environmental compliance requirements. The IL 716E provides identical electrical performance, isolation characteristics, and mechanical compatibility while meeting modern regulatory standards. The tube packaging format of the IL 716E is suitable for automated assembly processes and component handling in high-volume manufacturing environments.

Selection Basis:

Both parts are active products from the same manufacturer and series. The choice between IL 716 and IL 716E should be determined by:

1. Regulatory compliance requirements (RoHS3 certification)
2. Supply chain availability and lead times
3. Packaging format requirements (tube versus alternative formats)
4. End-market or application-specific compliance mandates

All electrical performance parameters, isolation ratings, timing specifications, and mechanical dimensions are identical between both variants, ensuring direct functional interchangeability in circuit design and PCB layout.

Frequently Asked Questions (FAQ)

Q: Can IL 716E be used as a direct replacement for IL 716 in existing designs?

A: Yes. The IL 716E is electrically and mechanically equivalent to the IL 716. All critical parameters including isolation voltage (2500Vrms), data rate (110Mbps), propagation delay (15ns), common mode transient immunity (100kV/µs), supply voltage range (3V–5.5V), and operating temperature range (-40°C to 100°C) are identical. The 16-SOIC package dimensions and pin configuration are unchanged. Direct substitution is possible without circuit redesign or PCB layout modification.

Q: What is the difference between IL 716 and IL 716E?

A: The primary differences are packaging format and RoHS compliance status. The IL 716E is supplied in tube packaging and meets ROHS3 compliance requirements, while the IL 716 does not specify RoHS compliance. All electrical performance specifications and mechanical dimensions remain identical.

Q: Are there any timing or performance differences between IL 716 and IL 716E?

A: No. Both parts share identical specifications for propagation delay (15ns maximum for both rising and falling edges), pulse width distortion (3ns maximum), rise/fall time (1ns typical), and all other electrical parameters. Performance in circuit operation is equivalent.

Q: What packaging formats are available for these parts?

A: The IL 716E is specified with tube packaging. The IL 716 packaging format is not explicitly specified in the provided data. For specific packaging requirements (tape-and-reel, tube, or alternative formats), consult the manufacturer's current product documentation or contact the supplier.

Q: Can these parts be used interchangeably in automated assembly?

A: Yes, provided the packaging format is compatible with the assembly equipment. The IL 716E tube packaging is suitable for automated pick-and-place systems. Both parts use identical 16-SOIC surface-mount packages with the same footprint and pin spacing, ensuring compatibility with standard PCB assembly processes.

Q: What is the isolation voltage rating, and is it sufficient for my application?

A: Both IL 716 and IL 716E provide 2500Vrms isolation voltage. This rating determines the maximum voltage differential that can be safely maintained between the isolated sides of the device. Verify that your application's isolation requirements do not exceed this specification.

Q: Are these parts suitable for high-speed digital signal isolation?

A: Yes. Both parts support data rates up to 110Mbps with a maximum propagation delay of 15ns and common mode transient immunity of 100kV/µs, making them suitable for high-speed digital isolation applications in industrial control, power conversion, and communication systems.

Q: What is the operating temperature range?

A: Both IL 716 and IL 716E operate across -40°C to 100°C. Verify that your application's thermal environment remains within this range during normal operation and worst-case conditions.

Q: What supply voltage range is supported?

A: Both parts operate with supply voltages between 3V and 5.5V. Ensure that your power supply design maintains voltage within this range under all operating conditions, including transient events and load variations.
