IL 613-3 Digital Isolator Equivalent & Substitute Parts

Part Overview

The IL 613-3 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 with a 2500Vrms isolation rating and 3 unidirectional channels. The IL 613-3 is classified as Obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The primary substitute maintains identical isolation voltage, channel configuration, and package form factor while offering enhanced performance characteristics and current product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IL 613-3 is determined by strict equivalence in the following critical parameters:

Mandatory Equivalence Parameters:

• Isolation voltage: 2500Vrms (identical)
• Number of channels: 3 (identical)
• Channel type: Unidirectional (identical)
• Package form factor: 16-SOIC (0.154", 3.90mm Width) (identical)
• Mounting type: Surface Mount (identical)
• Technology: GMR (Giant Magnetoresistive) (identical)
• Common Mode Transient Immunity: 15kV/µs minimum (identical)
• Supply voltage range: 3V to 5.5V (compatible)

Performance Enhancement Parameters: The substitute part IL 613-3E maintains all mandatory equivalence parameters while providing improved performance in data rate, propagation delay, and pulse width distortion. These enhancements do not compromise backward compatibility in applications designed for the IL 613-3 specifications.

Compliance Differentiation: The IL 613-3E is Active product status with ROHS3 compliance, whereas the IL 613-3 is Obsolete and RoHS non-compliant. This distinction is critical for new designs and regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The IL 613-3E is the direct substitute for IL 613-3 applications. Both parts share identical isolation voltage (2500Vrms), channel configuration (3 unidirectional), and package specifications (16-SOIC). The IL 613-3E is classified as Active product status, ensuring long-term availability and supply chain continuity.

For Regulatory Compliance: The IL 613-3E meets ROHS3 compliance requirements, whereas the IL 613-3 is RoHS non-compliant. New designs and production requiring RoHS certification must transition to IL 613-3E.

For Performance Enhancement: The IL 613-3E provides superior performance metrics: data rate increased from 40Mbps to 100Mbps, propagation delay reduced from 25ns to 15ns, and pulse width distortion reduced from 10ns to 5ns. These improvements are backward compatible with IL 613-3 application requirements.

Operating Temperature Consideration: The IL 613-3 operates from -55°C to 125°C, while IL 613-3E operates from -40°C to 85°C. Applications requiring extended low-temperature operation below -40°C must retain IL 613-3 or identify alternative solutions.

Frequently Asked Questions (FAQ)

Q: Can IL 613-3E directly replace IL 613-3 in existing designs?

A: Yes, IL 613-3E is a direct substitute for IL 613-3. Both parts maintain identical isolation voltage (2500Vrms), 3-channel unidirectional configuration, and 16-SOIC package form factor. The IL 613-3E provides enhanced performance without compromising backward compatibility.

Q: What is the primary reason to substitute IL 613-3 with IL 613-3E?

A: The IL 613-3 is classified as Obsolete, while IL 613-3E is Active. Substitution ensures long-term component availability, supply chain reliability, and access to current manufacturing processes. Additionally, IL 613-3E meets ROHS3 compliance.

Q: Are there any electrical parameter differences that affect circuit design?

A: The core isolation and channel specifications are identical. However, IL 613-3E offers improved propagation delay (15ns vs. 25ns) and pulse width distortion (5ns vs. 10ns), which may benefit high-speed applications. Operating temperature ranges differ: IL 613-3 supports -55°C to 125°C, while IL 613-3E supports -40°C to 85°C.

Q: Is the 16-SOIC package identical between both parts?

A: Yes, both IL 613-3 and IL 613-3E use the same 16-SOIC (0.154", 3.90mm Width) package. PCB layout and footprint compatibility are maintained.

Q: What is the difference in packaging between IL 613-3 and IL 613-3E?

A: IL 613-3 is supplied in bulk packaging, while IL 613-3E is supplied in tube packaging. This difference does not affect electrical or mechanical compatibility.

Q: Does IL 613-3E require design changes for integration?

A: No design changes are required. IL 613-3E maintains identical supply voltage range (3V to 5.5V), pin configuration, and functional specifications. Direct PCB substitution is possible.

Q: What certifications apply to IL 613-3E?

A: IL 613-3E is ROHS3 compliant and REACH unaffected. The IL 613-3 is RoHS non-compliant. For applications requiring environmental compliance, IL 613-3E is the appropriate selection.
