Key Parameters

Substitute Part Grouping Explanation

Substitution of the IL 610-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Isolation voltage: 2500Vrms
• Number of channels: 1
• Channel configuration: Unidirectional (1 input, 0 outputs on isolated side)
• Common mode transient immunity: 15kV/µs minimum
• Supply voltage range: 3V to 5.5V
• Package type: 8-DIP (0.300", 7.62mm)
• Mounting type: Through Hole

Allowable Variation Parameters:

• Data rate: May exceed 40Mbps (backward compatible)
• Propagation delay: May be lower (improved performance)
• Pulse width distortion: May be lower (improved performance)
• Operating temperature range: May be narrower or wider
• Product status: Active status preferred for new designs
• RoHS compliance: Improved compliance acceptable

The IL 610-2E qualifies as a direct substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

IL 610-2E as Primary Substitute:

The IL 610-2E is the direct substitute for the IL 610-2. Both components share identical isolation voltage, channel configuration, CMTI rating, supply voltage range, and physical package specifications. The IL 610-2E provides superior electrical performance with 100Mbps data rate capability versus 40Mbps, reduced propagation delays (15ns versus 25ns), and lower pulse width distortion (5ns versus 10ns).

Product Status Consideration:

The IL 610-2 is classified as obsolete, while the IL 610-2E maintains active product status. For new designs and long-term system support, the IL 610-2E is the recommended selection.

Compliance Status:

The IL 610-2E achieves ROHS3 compliance, whereas the IL 610-2 is non-compliant. Applications subject to RoHS regulatory requirements must transition to the IL 610-2E.

Operating Temperature Range:

The IL 610-2 supports -55°C to 125°C operation, while the IL 610-2E operates within -40°C to 85°C. Applications requiring extended low-temperature operation below -40°C must verify compatibility with the narrower temperature range of the IL 610-2E.

Packaging:

Both components utilize identical 8-DIP (0.300", 7.62mm) through-hole packaging, enabling direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the IL 610-2E directly replace the IL 610-2 in existing designs?

A: Yes, the IL 610-2E is a direct substitute. Both components share identical isolation voltage (2500Vrms), channel configuration (1 unidirectional channel), CMTI rating (15kV/µs), supply voltage range (3V to 5.5V), and package type (8-DIP). The IL 610-2E provides improved electrical performance with higher data rate capability and faster propagation delays. Verify that the operating temperature range of -40°C to 85°C meets application requirements, as the IL 610-2 supports extended operation to -55°C.

Q: What are the key differences between IL 610-2 and IL 610-2E?

A: The primary differences are data rate (40Mbps versus 100Mbps), propagation delay (25ns versus 15ns), pulse width distortion (10ns versus 5ns), product status (obsolete versus active), RoHS compliance (non-compliant versus ROHS3 compliant), and operating temperature range (-55°C to 125°C versus -40°C to 85°C). All isolation and channel specifications remain identical.

Q: Are there any PCB layout modifications required when substituting IL 610-2E for IL 610-2?

A: No PCB layout modifications are required. Both components use identical 8-DIP (0.300", 7.62mm) through-hole packaging with the same pin configuration and spacing. Direct component substitution is possible without PCB redesign.

Q: Does the IL 610-2E support the same isolation voltage as the IL 610-2?

A: Yes, both components provide 2500Vrms galvanic isolation and support identical 15kV/µs common mode transient immunity.

Q: What is the significance of the IL 610-2 being classified as obsolete?

A: Obsolete classification indicates that the IL 610-2 is no longer in active production. For new designs, ongoing system support, and long-term component availability, transition to the IL 610-2E is necessary. The IL 610-2E maintains active product status and is the recommended selection for all new applications.

Q: Is the IL 610-2E suitable for applications requiring extended temperature operation below -40°C?

A: The IL 610-2E operates within -40°C to 85°C. Applications requiring operation below -40°C must verify compatibility with this narrower temperature range. The original IL 610-2 supports -55°C to 125°C operation; however, due to obsolete status, alternative components with extended low-temperature capability should be evaluated for such applications.
