IL 717T Digital Isolator - Equivalent & Substitute Parts

Part Overview

The IL 717T 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 717T is actively produced and maintains 681 pieces in current inventory stock.

Digital isolators are essential in applications requiring electrical isolation between circuits operating at different voltage potentials or ground references. The IL 717T serves this function in systems requiring high-speed signal isolation with robust common-mode transient immunity. Substitute parts are identified to address packaging preferences, compliance requirements, or inventory availability while maintaining identical electrical and functional performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IL 717T is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Isolation voltage rating: 2500Vrms
• Number of channels: 4
• Channel configuration: 3 inputs / 1 output (unidirectional)
• Data rate: 110Mbps
• Common mode transient immunity: 100kV/µs minimum
• Propagation delay specifications: 15ns maximum (both rising and falling edges)
• Supply voltage range: 3V ~ 5.5V
• Operating temperature range: -40°C ~ 125°C

Mechanical Equivalence Criteria:

• Package type: 16-SOIC (0.295", 7.50mm Width)
• Mounting type: Surface Mount
• Base product number: IL 717

Functional Equivalence:

• Technology platform: GMR (Giant Magnetoresistive)
• Series designation: IsoLoop®
• Type classification: General Purpose

Parts meeting all electrical, mechanical, and functional criteria are classified as parametric equivalents and direct substitutes. Packaging format (tube versus standard packaging) does not affect electrical or functional compatibility and represents a logistics variable only.

Parameter Comparison

Engineering Selection Recommendations

IL 717T Selection Criteria:

The IL 717T is the appropriate choice when standard packaging format is required and RoHS non-compliant components are acceptable for the application. This variant carries ECCN classification 5A991A, which may affect export documentation requirements depending on destination jurisdiction.

IL 717TE Selection Criteria:

The IL 717TE is the appropriate choice when ROHS3 compliance is mandated by design specifications, procurement standards, or end-use regulations. This variant carries EAR99 export classification, which typically simplifies export documentation compared to the 5A991A classification. The IL 717TE is supplied in tube packaging format and maintains significantly higher inventory availability (6035 pieces versus 681 pieces for IL 717T).

Substitution Logic:

Both parts are parametric equivalents across all electrical, functional, and mechanical specifications. Selection between IL 717T and IL 717TE depends on:

1. Regulatory Compliance Requirements: If ROHS3 compliance is specified, IL 717TE is required. If RoHS compliance is not a constraint, either part is acceptable.

2. Export Control Requirements: If EAR99 classification is preferred for supply chain simplification, IL 717TE is indicated. If 5A991A classification is acceptable, IL 717T is acceptable.

3. Inventory and Lead Time: IL 717TE maintains substantially higher stock levels, reducing procurement lead time risk.

4. Packaging Preference: IL 717TE is supplied in tube format; IL 717T uses standard packaging. Tube packaging may be preferred for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Are IL 717T and IL 717TE electrically identical?

A: Yes. Both parts are parametric equivalents with identical electrical specifications across all measured parameters: isolation voltage (2500Vrms), channel count (4), data rate (110Mbps), propagation delay (15ns), CMTI (100kV/µs), and supply voltage range (3V ~ 5.5V). They are functionally interchangeable in circuit applications.

Q: What is the difference between IL 717T and IL 717TE?

A: The primary differences are: (1) RoHS compliance status—IL 717TE is ROHS3 compliant while IL 717T is non-compliant; (2) export classification—IL 717TE carries EAR99 classification while IL 717T carries 5A991A; (3) packaging format—IL 717TE is supplied in tube packaging; (4) inventory availability—IL 717TE has significantly higher stock (6035 vs. 681 pieces).

Q: Can I substitute IL 717TE for IL 717T in my design?

A: Yes, IL 717TE is a direct parametric substitute for IL 717T. All electrical, mechanical, and functional specifications are identical. If your design does not require RoHS non-compliance specifically, IL 717TE is the preferred choice due to higher compliance status and inventory availability.

Q: Can I substitute IL 717T for IL 717TE?

A: IL 717T is a parametric equivalent to IL 717TE. However, if your application or procurement specification mandates ROHS3 compliance, IL 717T is not acceptable. Verify compliance requirements before substituting IL 717T for IL 717TE.

Q: Does packaging format (tube vs. standard) affect electrical performance?

A: No. Packaging format is a logistics variable only and does not affect electrical performance, signal integrity, or functional operation. Both tube and standard packaging contain identical components with identical specifications.

Q: What does the "TE" suffix in IL 717TE indicate?

A: The "TE" suffix indicates tube packaging format and ROHS3 compliance status. The base product number IL 717 identifies the core component design; suffix variations indicate packaging and compliance differences only.

Q: Are there any temperature or voltage derating differences between IL 717T and IL 717TE?

A: No. Both parts operate across the identical temperature range (-40°C ~ 125°C) and supply voltage range (3V ~ 5.5V). Derating curves and thermal characteristics are identical.

Q: Which part should I specify for new designs?

A: IL 717TE is the recommended choice for new designs due to ROHS3 compliance alignment with current regulatory trends and significantly higher inventory availability, reducing supply chain risk.
