HCPL-9000 General Purpose Digital Isolator 2500Vrms 1 Channel

Part Overview

The HCPL-9000 is a general purpose digital isolator manufactured by Broadcom Limited, utilizing Giant Magnetoresistive (GMR) technology to provide 2500Vrms isolation for single-channel unidirectional signal transmission. The device operates at 110MBd data rate with 15kV/µs common mode transient immunity in an 8-DIP (0.300", 7.62mm) through-hole package. The product is currently active in production. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits selection from qualified alternatives meeting the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-9000 is determined by strict equivalence across the following critical parameters:

• Isolation voltage: 2500Vrms (all substitutes meet this requirement)
• Number of channels: 1 (all substitutes meet this requirement)
• Channel type: Unidirectional (all substitutes meet this requirement)
• Data rate: 110MBd/110Mbps (all substitutes meet this requirement)
• Propagation delay: 15ns maximum (all substitutes meet this requirement)
• Pulse width distortion: 3ns maximum (all substitutes meet this requirement)
• Supply voltage: 3V to 5.5V (all substitutes meet this requirement)
• Package: 8-DIP (0.300", 7.62mm) through-hole (all substitutes meet this requirement)
• Technology: GMR (all substitutes meet this requirement)

Substitutes are classified into three categories based on manufacturer designation and compliance status:

Parametric Equivalent: HCPL-9000-000E (Broadcom Limited) — identical electrical specifications with improved RoHS3 compliance.

Direct Manufacturer Alternatives: IL 710-2 and IL 710-2E (NVE Corp/Isolation Products) — meet all core electrical parameters with enhanced common mode transient immunity (100kV/µs vs. 15kV/µs).

Manufacturer Recommended: IL 710T-2E (NVE Corp/Isolation Products) — extended operating temperature range (-40°C to 125°C) with manufacturer recommendation status.

Parameter Comparison

Engineering Selection Recommendations

HCPL-9000-000E is the direct parametric equivalent from Broadcom Limited. Selection of this part is appropriate when maintaining single-source supplier preference or when RoHS3 compliance is required. All electrical and mechanical specifications are identical to the HCPL-9000.

IL 710-2E is suitable for applications requiring RoHS3 compliance with enhanced common mode transient immunity (100kV/µs). Operating temperature range is -40°C to 100°C, which is narrower than the HCPL-9000 at the low end (-55°C vs. -40°C) and at the high end (100°C vs. 125°C). This part is available in tube packaging.

IL 710T-2E is the manufacturer-recommended substitute from NVE Corp/Isolation Products. This variant extends the high-temperature operating range to 125°C, matching the HCPL-9000 upper limit, while maintaining the -40°C lower limit. RoHS3 compliance and enhanced common mode transient immunity (100kV/µs) are provided. This part is available in tube packaging.

Selection between IL 710-2E and IL 710T-2E depends on operating temperature requirements. For applications operating below -40°C or requiring the full -55°C to 125°C range, the HCPL-9000 or HCPL-9000-000E remain the appropriate choice.

Frequently Asked Questions (FAQ)

Q: Can IL 710-2 or IL 710-2E be used as direct replacements for HCPL-9000 in existing designs?

A: Yes, provided the application operating temperature range does not exceed -40°C to 100°C. All core electrical parameters (isolation voltage, data rate, propagation delay, pulse width distortion, and supply voltage) are identical. The enhanced common mode transient immunity (100kV/µs vs. 15kV/µs) of the IL 710 series provides additional margin in high-noise environments.

Q: What is the difference between IL 710-2 and IL 710-2E?

A: Both parts are electrically identical. IL 710-2E is supplied in tube packaging and meets ROHS3 compliance. IL 710-2 packaging is not specified in the provided data. For new designs, IL 710-2E is preferred due to RoHS3 compliance status.

Q: Why does IL 710T-2E have a different operating temperature range than IL 710-2E?

A: IL 710T-2E extends the maximum operating temperature to 125°C, matching the HCPL-9000 specification. The "T" designation indicates this temperature-extended variant. Selection depends on whether the application requires operation at temperatures above 100°C.

Q: Are all substitute parts available in the same 8-DIP package?

A: Yes. All parts listed use the 8-DIP (0.300", 7.62mm) through-hole package. Pin-for-pin compatibility is maintained across all substitutes.

Q: What is the significance of the enhanced common mode transient immunity in the IL 710 series?

A: The IL 710 series provides 100kV/µs common mode transient immunity compared to 15kV/µs for the HCPL-9000. This higher immunity specification indicates improved performance in applications with high-speed switching transients or noisy power distribution environments. Applications designed for the HCPL-9000 specification will operate within the IL 710 margin.

Q: Which substitute part should be selected for new designs?

A: For new designs requiring RoHS3 compliance and extended temperature range (-40°C to 125°C), IL 710T-2E is the manufacturer-recommended choice. For applications with temperature limits of -40°C to 100°C, IL 710-2E is suitable. For designs requiring the full -55°C to 125°C range, HCPL-9000-000E maintains Broadcom supply with RoHS3 compliance.
