HCPL-9030-300E Equivalent & Substitute Parts

Part Overview

The HCPL-9030-300E is a general purpose digital isolator manufactured by Broadcom Limited, utilizing GMR (Giant Magnetoresistive) technology. This 2-channel, unidirectional isolator provides 2500Vrms isolation with a data rate of 110MBd and 15kV/µs common mode transient immunity. The device is housed in an 8-SMD, Gull Wing package and operates across a supply voltage range of 3V to 5.5V with an operating temperature range of -55°C to 125°C. The HCPL-9030-300E maintains Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical isolation, channel configuration, and mechanical compatibility can be maintained within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-9030-300E is determined by the following critical parameters:

• Isolation Voltage: 2500Vrms minimum
• Number of Channels: 2 channels required
• Channel Configuration: Unidirectional input/output structure (2 inputs on Side 1, 0 inputs on Side 2)
• Common Mode Transient Immunity: 15kV/µs minimum
• Technology: GMR-based isolation
• Supply Voltage Compatibility: 3V to 5.5V operating range
• Package Type: Surface mount configuration with compatible pinout

The IL 611A-3E qualifies as a substitute based on matching isolation voltage, channel count, channel configuration, CMTI rating, technology platform, and supply voltage range. Package differences (8-SOIC versus 8-SMD, Gull Wing) require mechanical verification for board layout compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the HCPL-9030-300E and IL 611A-3E maintain Active product status and are ROHS3 compliant, confirming ongoing manufacturer support and environmental regulation adherence. Selection between these parts depends on application-specific requirements:

The HCPL-9030-300E is suitable for applications requiring higher data rates (110MBd versus 10Mbps), lower propagation delays (15ns versus 75ns/25ns), and extended operating temperature range (-55°C to 125°C). This part is optimal for high-speed signal isolation in industrial and automotive environments with demanding thermal specifications.

The IL 611A-3E serves applications where lower data rates are acceptable and cost optimization is prioritized. The narrower operating temperature range (-40°C to 85°C) restricts deployment to commercial and industrial environments without extreme temperature exposure.

Package compatibility must be verified during design integration. The 8-SMD, Gull Wing package of the HCPL-9030-300E differs mechanically from the 8-SOIC package of the IL 611A-3E, requiring PCB layout and footprint validation.

Frequently Asked Questions (FAQ)

Q: Can the IL 611A-3E directly replace the HCPL-9030-300E on an existing PCB?

A: Direct PCB replacement is not possible without layout modification. The HCPL-9030-300E uses an 8-SMD, Gull Wing package while the IL 611A-3E uses an 8-SOIC (0.154", 3.90mm Width) package. Footprint redesign and revalidation are required.

Q: What are the key electrical differences between these isolators?

A: Both devices provide identical isolation voltage (2500Vrms), channel count (2), channel configuration (unidirectional), and CMTI rating (15kV/µs). The primary differences are data rate (110MBd versus 10Mbps) and propagation delay characteristics. The HCPL-9030-300E delivers superior timing performance suitable for high-speed applications.

Q: Are both parts suitable for automotive applications?

A: The HCPL-9030-300E supports the extended temperature range (-55°C to 125°C) required for automotive environments. The IL 611A-3E operates within -40°C to 85°C, limiting its use to commercial and light industrial applications. Automotive deployment of the IL 611A-3E requires thermal management verification.

Q: Do both isolators require isolated power supplies?

A: No. Both the HCPL-9030-300E and IL 611A-3E are general purpose isolators without integrated isolated power. External isolated power supplies must be provided for the secondary side circuitry.

Q: What compliance certifications apply to both parts?

A: Both devices are ROHS3 compliant and REACH unaffected. The HCPL-9030-300E carries ECCN classification EAR99, while the IL 611A-3E carries ECCN 5A991A. Verify export compliance requirements for your application jurisdiction.
