Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IL 711T-1E are identified based on the following critical parameters that define functional equivalence:

Core Substitution Criteria:

• Number of Channels: 2 (unidirectional configuration)
• Channel Type: Unidirectional (2 inputs / 0 outputs)
• Data Rate: 110Mbps or higher
• Propagation Delay: 15ns or lower (tpLH / tpHL)
• Pulse Width Distortion: 3ns or lower
• Voltage - Supply: 3V ~ 5.5V compatibility
• Mounting Type: Surface Mount
• Technology: GMR-based isolation
• RoHS3 Compliance: Required

Isolation Voltage Consideration: The IL 711T-1E specifies 1000Vrms isolation. Substitute parts with higher isolation voltage ratings (2500Vrms) are functionally compatible and provide enhanced isolation margin. Lower isolation voltage ratings are not acceptable substitutes.

Package Compatibility: The IL 711T-1E uses 8-TSSOP/8-MSOP packaging. Substitute parts must use compatible 8-pin surface mount packages (8-SO, 8-SMD Gull Wing) with equivalent pinout and footprint dimensions.

Temperature Range: The IL 711T-1E operates from -40°C to 125°C. Substitute parts with extended temperature ranges (-55°C to 125°C) are acceptable and provide additional operational margin.

Parameter Comparison

Engineering Selection Recommendations

HCPL-9030-300E and HCPL-9030-500E (Broadcom Limited)

Both HCPL-9030 variants are active products from Broadcom Limited and serve as direct functional substitutes for the discontinued IL 711T-1E. The primary differences between these two substitute options relate to packaging and inventory form factor:

HCPL-9030-300E: Supplied in Tube packaging format. Suitable for lower-volume production runs and manual assembly operations.

HCPL-9030-500E: Supplied in Tape & Reel (TR) format. Optimized for high-volume automated assembly and pick-and-place manufacturing processes.

Functional Equivalence: Both HCPL-9030 variants maintain identical electrical specifications across all critical parameters: 2-channel unidirectional configuration, 110MBd data rate, 15ns propagation delay, 3ns pulse width distortion, and 3V to 5.5V supply voltage compatibility. Both components are ROHS3 compliant and REACH unaffected.

Isolation Voltage Enhancement: The HCPL-9030 series provides 2500Vrms isolation voltage, which exceeds the IL 711T-1E specification of 1000Vrms. This represents a 2.5x improvement in isolation margin and is fully backward compatible for applications designed around the lower isolation rating.

Temperature Range Extension: Both HCPL-9030 variants operate across -55°C to 125°C, extending the lower temperature limit by 15°C compared to the IL 711T-1E (-40°C to 125°C). This provides additional operational margin for extended temperature applications.

Product Status and Supply: Both HCPL-9030 variants are active products with confirmed inventory availability (675 Pcs for HCPL-9030-300E; 869 Pcs for HCPL-9030-500E), ensuring long-term supply continuity and design support.

Selection Criteria: Choose HCPL-9030-500E for production environments utilizing automated assembly equipment and tape-and-reel component handling. Choose HCPL-9030-300E for prototype development, low-volume production, or manual assembly workflows where tube packaging is preferred.

Frequently Asked Questions (FAQ)

Q: Can HCPL-9030-300E and HCPL-9030-500E be used interchangeably with IL 711T-1E?

A: Yes. Both HCPL-9030 variants are functionally equivalent to the IL 711T-1E across all critical electrical parameters: 2-channel unidirectional configuration, 110Mbps/110MBd data rate, 15ns propagation delay, 3ns pulse width distortion, and 3V to 5.5V supply voltage. The primary difference is packaging format (Tube vs. Tape & Reel) and inventory availability, not electrical performance.

Q: What is the significance of the higher 2500Vrms isolation voltage in the HCPL-9030 series?

A: The HCPL-9030 series provides 2500Vrms isolation compared to the IL 711T-1E's 1000Vrms specification. This 2.5x improvement in isolation voltage rating provides enhanced safety margin and is fully compatible with applications designed for the lower 1000Vrms rating. Higher isolation voltage does not negatively impact circuit performance or compatibility.

Q: Are there package compatibility concerns when substituting IL 711T-1E with HCPL-9030 variants?

A: Both HCPL-9030 variants use 8-pin surface mount packages (8-SMD, Gull Wing) compatible with the IL 711T-1E's 8-TSSOP/8-MSOP footprint. PCB layout verification is required to confirm pinout alignment and footprint compatibility for your specific application. Consult component datasheets for detailed package dimensions and pin assignments.

Q: What is the difference between HCPL-9030-300E and HCPL-9030-500E?

A: Both parts are electrically identical. The difference is packaging format: HCPL-9030-300E is supplied in Tube packaging for lower-volume or manual assembly applications. HCPL-9030-500E is supplied in Tape & Reel (TR) format for high-volume automated assembly. Select based on your manufacturing process and assembly equipment capabilities.

Q: Are HCPL-9030 variants compliant with RoHS and REACH regulations?

A: Yes. Both HCPL-9030-300E and HCPL-9030-500E are ROHS3 compliant and REACH unaffected, matching the regulatory compliance status of the IL 711T-1E. Both components maintain MSL 1 (Unlimited) moisture sensitivity level.

Q: What is the operating temperature range difference between IL 711T-1E and HCPL-9030 variants?

A: The IL 711T-1E operates from -40°C to 125°C. Both HCPL-9030 variants operate from -55°C to 125°C, providing an additional 15°C of lower temperature margin. This extended range is fully backward compatible and beneficial for applications requiring operation in colder environments.

Q: Why is the IL 711T-1E discontinued?

A: The IL 711T-1E is discontinued at DiGi Electronics. The HCPL-9030 series from Broadcom Limited represents the active product line for equivalent 2-channel general purpose digital isolators with GMR technology and comparable electrical specifications.

Q: Can I use HCPL-9030 variants in existing IL 711T-1E designs without circuit modifications?

A: Electrical compatibility is confirmed across all critical parameters. However, PCB layout verification is required to confirm package footprint and pinout alignment. Consult both component datasheets and perform design validation before production implementation.
