IL 613 Digital Isolator Equivalent & Substitute Parts

Part Overview

The IL 613 is a general purpose digital isolator manufactured by NVE Corp/Isolation Products, featuring 3-channel unidirectional isolation at 2500Vrms with GMR (Giant Magnetoresistive) technology. The device operates at 40Mbps data rate with 15kV/µs common mode transient immunity in a 16-SOIC surface mount package.

The IL 613 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this isolator.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IL 613 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Isolation voltage rating of 2500Vrms or higher
• Minimum 3 channels with unidirectional input configuration (3 inputs, 0 outputs)
• 16-SOIC surface mount package compatibility
• Supply voltage range overlap with 3V to 5.5V
• Common mode transient immunity of 15kV/µs or greater

Secondary Compatibility Considerations:

• Data rate performance (minimum 40Mbps for direct functional replacement)
• Propagation delay characteristics
• Operating temperature range coverage
• RoHS and regulatory compliance status

Two substitute parts meet the primary compatibility criteria:

1. IL 613E (NVE Corp/Isolation Products) – Direct manufacturer upgrade with enhanced performance specifications while maintaining identical isolation voltage, channel configuration, and package format.

2. ACSL-6300-00TE (Broadcom Limited) – Cross-manufacturer alternative using optoisolator technology instead of GMR, meeting isolation voltage and channel requirements but with different output architecture and reduced data rate performance.

Engineering Selection Recommendations

IL 613E – Recommended Direct Replacement

The IL 613E is the preferred substitute for IL 613 applications. Both devices share identical isolation voltage (2500Vrms), channel configuration (3 unidirectional inputs), and package footprint (16-SOIC 0.295" width). The IL 613E offers superior performance with 100Mbps data rate versus 40Mbps, reduced propagation delay (15ns vs. 25ns), and improved pulse width distortion (5ns vs. 10ns). The IL 613E maintains active product status and achieves ROHS3 compliance, addressing regulatory requirements for new designs and production continuity.

The primary design consideration is the reduced operating temperature range of IL 613E (-40°C to 85°C) compared to IL 613 (-55°C to 125°C). Applications requiring operation below -40°C or above 85°C must evaluate thermal requirements against system specifications.

ACSL-6300-00TE – Cross-Manufacturer Alternative

The ACSL-6300-00TE provides an alternative isolation solution when IL 613E availability is constrained. This Broadcom optoisolator maintains 2500Vrms isolation and 3-channel configuration with active product status and ROHS3 compliance. However, significant performance differences require engineering evaluation:

• Data rate is reduced to 15MBd (37.5% of IL 613 specification)
• Propagation delay increases to 100ns (4× IL 613 specification)
• Common mode transient immunity is 10kV/µs (33% reduction from IL 613)
• Output architecture differs (open collector with Schottky clamping vs. digital logic output)
• Package width is 0.154" (3.90mm) versus 0.295" (7.50mm), requiring PCB layout modification

The ACSL-6300-00TE is suitable only for applications where reduced data rate and increased propagation delay do not compromise system performance. Circuit-level redesign may be necessary to accommodate output impedance and current drive characteristics.

Frequently Asked Questions (FAQ)

Q: Can IL 613E be used as a direct pin-for-pin replacement for IL 613?

A: Yes. Both devices use identical 16-SOIC (0.295", 7.50mm) packaging with matching pinout for 3-channel unidirectional input configuration. PCB layout and footprint remain unchanged. No circuit modification is required for basic substitution.

Q: What is the primary limitation when substituting IL 613E for IL 613?

A: The IL 613E operating temperature range (-40°C to 85°C) is narrower than IL 613 (-55°C to 125°C). Applications requiring operation at temperatures below -40°C or above 85°C must verify thermal compatibility. High-temperature applications above 85°C cannot use IL 613E without design modification.

Q: Is ACSL-6300-00TE a suitable replacement for high-speed applications?

A: No. The ACSL-6300-00TE data rate of 15MBd is significantly lower than IL 613 (40Mbps) and IL 613E (100Mbps). Propagation delay of 100ns versus 25ns (IL 613) introduces timing constraints. This device is suitable only for low-speed isolation applications where data rate and timing margins are not critical.

Q: What are the key differences between IL 613 and IL 613E technology?

A: Both devices use GMR (Giant Magnetoresistive) technology and share identical isolation voltage (2500Vrms) and CMTI (15kV/µs). The IL 613E represents a performance enhancement with doubled data rate (100Mbps vs. 40Mbps), reduced propagation delay (15ns vs. 25ns), and improved pulse width distortion (5ns vs. 10ns). Both maintain identical supply voltage range (3V to 5.5V) and package format.

Q: Why does ACSL-6300-00TE use different technology than IL 613?

A: ACSL-6300-00TE is an optoisolator using LED and photodiode technology, whereas IL 613 uses GMR magnetic isolation. Both technologies achieve 2500Vrms isolation but with different performance characteristics. Optoisolators typically exhibit higher propagation delay and lower data rates but provide alternative isolation mechanisms for specific application requirements.

Q: Are there PCB layout considerations when substituting ACSL-6300-00TE?

A: Yes. ACSL-6300-00TE uses 16-SOIC (0.154", 3.90mm width) packaging versus IL 613 (0.295", 7.50mm width). The narrower package requires PCB footprint modification. Additionally, open collector output architecture requires external pull-up resistors and may require circuit redesign compared to digital logic output of IL 613.

Q: What is the RoHS compliance status for each device?

A: IL 613 is RoHS non-compliant. IL 613E and ACSL-6300-00TE are both ROHS3 compliant. For new designs or applications subject to RoHS regulations, IL 613E or ACSL-6300-00TE must be selected.

Q: Can IL 613 be used in new production designs?

A: No. IL 613 carries obsolete product status. New designs must use IL 613E (recommended) or ACSL-6300-00TE (alternative). Existing production using IL 613 should transition to IL 613E to ensure long-term supply chain continuity and regulatory compliance.
