IL 611A-2 Digital Isolator Equivalent & Substitute Parts

Part Overview

The IL 611A-2 is a general purpose digital isolator manufactured by NVE Corp/Isolation Products, part of the IsoLoop® series. This component provides 2500Vrms isolation across 2 channels with a data rate of 10Mbps and 15kV/µs common mode transient immunity. The device utilizes Giant Magnetoresistive (GMR) technology and is housed in an 8-DIP (0.300", 7.62mm) through-hole package.

The IL 611A-2 carries an obsolete product status. Locating equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this isolator.

• Number of Channels: 2
• Channel Type: Unidirectional
• Voltage - Isolation: 2500Vrms
• Data Rate: 10Mbps
• Common Mode Transient Immunity: 15kV/µs
• Voltage - Supply Range: 3V ~ 5.5V
• Package / Case: 8-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole

The IL 611A-2E qualifies as a direct substitute based on identical electrical specifications and package configuration. Differences in product status, operating temperature range, and compliance certifications do not affect functional interchangeability within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

IL 611A-2E as Primary Substitute:

The IL 611A-2E is the direct equivalent substitute for the obsolete IL 611A-2. Both components share identical electrical performance specifications, including isolation voltage, data rate, common mode transient immunity, and supply voltage range. The 8-DIP through-hole package is identical, ensuring direct PCB compatibility without layout modifications.

The IL 611A-2E carries active product status, ensuring ongoing availability and supply chain support. The component is ROHS3 compliant, meeting current regulatory requirements for new designs and manufacturing environments. Both parts maintain REACH unaffected status and identical export control classifications (ECCN 5A991A).

The operating temperature range differs between the two parts: the IL 611A-2 operates from -55°C to 125°C, while the IL 611A-2E operates from -40°C to 85°C. This difference must be evaluated against specific application temperature requirements. For applications operating within the -40°C to 85°C range, the IL 611A-2E provides full functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can the IL 611A-2E directly replace the IL 611A-2 in existing designs?

A: The IL 611A-2E is electrically and mechanically equivalent to the IL 611A-2 across all critical parameters: isolation voltage, data rate, common mode transient immunity, supply voltage, and package configuration. Direct PCB substitution is possible without design modifications. Operating temperature range differences must be verified against application requirements.

Q: What is the difference between IL 611A-2 and IL 611A-2E?

A: The primary differences are product status, compliance certifications, and operating temperature range. The IL 611A-2 is obsolete and RoHS non-compliant, while the IL 611A-2E is active and ROHS3 compliant. The IL 611A-2 operates from -55°C to 125°C; the IL 611A-2E operates from -40°C to 85°C. Electrical specifications and package configuration are identical.

Q: Are there packaging differences between these parts?

A: Both parts use the 8-DIP (0.300", 7.62mm) through-hole package with identical pin configurations. The IL 611A-2E is supplied in tube packaging, while the IL 611A-2 packaging format is not specified. Both are suitable for through-hole PCB assembly.

Q: What certifications apply to the IL 611A-2E?

A: The IL 611A-2E is ROHS3 compliant and REACH unaffected. Both parts share identical ECCN (5A991A) and HTSUS (8542.39.0001) classifications. Moisture sensitivity level is 1 (unlimited) for both components.

Q: Is the IL 611A-2E suitable for high-temperature applications?

A: The IL 611A-2E operates from -40°C to 85°C. Applications requiring operation above 85°C or below -40°C must evaluate alternative components or confirm that the IL 611A-2E meets specific thermal requirements.
