IL 612-2 Digital Isolator Equivalent & Substitute Parts

Part Overview

The IL 612-2 is a general purpose digital isolator manufactured by NVE Corp/Isolation Products, utilizing Giant Magnetoresistive (GMR) technology. This component provides 2500Vrms isolation across 2 channels with a maximum data rate of 40Mbps and 15kV/µs common mode transient immunity. The IL 612-2 is classified as obsolete product status, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical isolation specifications, channel configuration, and physical package compatibility while meeting current compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IL 612-2 is determined by strict equivalence across the following critical parameters:

Mandatory Equivalence Criteria:

• Voltage isolation rating: 2500Vrms minimum
• Number of channels: 2 channels
• Channel configuration: Unidirectional
• Common mode transient immunity: 15kV/µs minimum
• Package type: 8-DIP (0.300", 7.62mm) through-hole
• Supply voltage range: 3V to 5.5V compatible
• Technology platform: GMR-based isolation

Allowable Variations:

• Data rate may exceed 40Mbps (backward compatible)
• Propagation delay may be lower (improved performance)
• Operating temperature range may be narrower (acceptable if application requirements are met)
• Product status transition from obsolete to active (required for new production)
• RoHS compliance upgrade (required for current manufacturing standards)

The IL 612-2E qualifies as a direct substitute based on identical isolation voltage, channel count, CMTI rating, package configuration, and supply voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

IL 612-2E as Primary Substitute:

The IL 612-2E is the direct equivalent for IL 612-2 applications. Both components share identical isolation voltage (2500Vrms), channel configuration (2 unidirectional channels), CMTI rating (15kV/µs), package type (8-DIP through-hole), and supply voltage range (3V to 5.5V).

The IL 612-2E provides performance enhancements over the original IL 612-2: data rate increases from 40Mbps to 100Mbps, propagation delay decreases from 25ns to 15ns, and pulse width distortion reduces from 10ns to 5ns. These improvements are backward compatible with IL 612-2 designs.

Compliance Considerations:

The IL 612-2 is classified as obsolete and RoHS non-compliant. The IL 612-2E is active product status and ROHS3 compliant, meeting current manufacturing and environmental standards. Both components maintain identical REACH and ECCN classifications.

Operating Temperature Range:

The IL 612-2 operates across -55°C to 125°C, while IL 612-2E operates across -40°C to 85°C. Applications requiring operation below -40°C or above 85°C must retain the IL 612-2 or identify alternative isolators with extended temperature specifications. For standard industrial and commercial temperature ranges, IL 612-2E is suitable.

Packaging and Inventory:

IL 612-2E is supplied in tube packaging with 985 pieces in stock. IL 612-2 inventory of 776 pieces is available as obsolete stock. New designs must transition to IL 612-2E for long-term supply assurance.

Frequently Asked Questions (FAQ)

Q: Can IL 612-2E directly replace IL 612-2 in existing PCB designs?

A: Yes. Both components use identical 8-DIP (0.300", 7.62mm) through-hole package configuration with matching pinout. No PCB layout modifications are required. The IL 612-2E provides improved electrical performance (higher data rate, lower propagation delay) while maintaining backward compatibility.

Q: What are the key differences between IL 612-2 and IL 612-2E?

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. ROHS3 compliant), data rate (40Mbps vs. 100Mbps), propagation delay (25ns vs. 15ns), and operating temperature range (-55°C to 125°C vs. -40°C to 85°C). Isolation voltage, channel count, CMTI rating, and package type remain identical.

Q: Are there applications where IL 612-2 cannot be substituted with IL 612-2E?

A: Applications requiring operation below -40°C or above 85°C must use IL 612-2 or identify alternative isolators with extended temperature specifications. IL 612-2E is suitable for standard industrial (-40°C to 85°C) and commercial temperature ranges.

Q: What is the impact of IL 612-2 obsolescence on supply chain?

A: IL 612-2 is classified as obsolete product. Existing inventory of 776 pieces is available as new original stock. For new production and long-term designs, IL 612-2E (active status, 985 pieces in stock) is the required transition path. IL 612-2E ensures supply continuity and compliance with current manufacturing standards.

Q: Does IL 612-2E require different circuit design considerations?

A: No. IL 612-2E maintains identical isolation voltage (2500Vrms), supply voltage range (3V to 5.5V), and CMTI rating (15kV/µs). Circuit design, PCB layout, and application schematics developed for IL 612-2 are directly compatible with IL 612-2E. The improved performance characteristics (higher data rate, lower propagation delay) do not introduce design constraints.

Q: What certifications and compliance standards apply to IL 612-2E?

A: IL 612-2E is ROHS3 compliant and REACH unaffected. Both IL 612-2 and IL 612-2E share identical ECCN (5A991A) and HTSUS (8542.39.0001) classifications. Moisture sensitivity level is 1 (unlimited) for both components.

Q: Can IL 612-2E be used in high-speed applications exceeding 40Mbps?

A: Yes. IL 612-2E supports data rates up to 100Mbps, enabling use in applications requiring higher bandwidth than the original IL 612-2 (40Mbps maximum). Propagation delay of 15ns (vs. 25ns for IL 612-2) and pulse width distortion of 5ns (vs. 10ns for IL 612-2) provide improved timing performance for high-speed signal isolation.
