HCPL-0900-500 Digital Isolator Equivalent & Substitute Parts

Part Overview

The HCPL-0900-500 is a general purpose digital isolator manufactured by Broadcom Limited, utilizing Giant Magnetoresistive (GMR) technology to provide 2500Vrms isolation across a single unidirectional channel. This 8-SOIC surface mount component operates at data rates up to 110MBd with 15kV/µs common mode transient immunity, supporting supply voltages from 3V to 5.5V across an operating temperature range of -55°C to 125°C. The part is currently active in production with 728 units in stock. Equivalent and substitute parts are identified to address inventory availability, compliance requirements, or specific application performance needs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-0900-500 is determined by the following critical parameters: isolation voltage (2500Vrms), single unidirectional channel configuration, 8-SOIC package form factor, surface mount mounting type, and supply voltage range (3V to 5.5V). All identified substitutes maintain these core electrical and mechanical specifications. Differences in common mode transient immunity, data rate, propagation delay, and technology platform are noted but do not preclude functional substitution when application requirements permit. RoHS compliance status and operating temperature range variations are documented for design and procurement considerations.

Parameter Comparison

Engineering Selection Recommendations

HCPL-0900-500E (Broadcom Limited): Direct parametric equivalent with identical electrical specifications and package form factor. ROHS3 compliant status provides regulatory advantage over the original HCPL-0900-500. Highest inventory availability at 3277 units supports procurement flexibility. Recommended for new designs or applications requiring RoHS compliance.

IL 710-3 (NVE Corp/Isolation Products): Functionally compatible with enhanced common mode transient immunity (100kV/µs versus 15kV/µs). Operating temperature range limited to -40°C to 100°C. RoHS non-compliant. Suitable for applications requiring superior noise immunity in high-speed switching environments within the specified temperature range.

IL 710T-3E (NVE Corp/Isolation Products): Functionally compatible with enhanced common mode transient immunity (100kV/µs) and full operating temperature range (-40°C to 125°C). ROHS3 compliant. Tube packaging differs from tape and reel format. Recommended for applications requiring extended temperature operation and regulatory compliance.

SI8610AB-B-ISR (Skyworks Solutions Inc.): Functionally compatible with lower data rate (1Mbps) and extended supply voltage range (2.5V to 5.5V). Capacitive coupling technology differs from GMR platform. ROHS3 compliant. Moisture sensitivity level 2A requires controlled storage conditions. Suitable for low-speed isolation applications with extended supply voltage requirements.

Frequently Asked Questions (FAQ)

Q: Can HCPL-0900-500E be used as a direct replacement for HCPL-0900-500?

A: Yes. HCPL-0900-500E maintains identical electrical specifications, package form factor, and pin configuration. The primary difference is ROHS3 compliance status. Both parts operate at 110MBd data rate with 15kV/µs common mode transient immunity in 8-SOIC surface mount packages.

Q: What are the key differences between Broadcom and NVE substitute options?

A: Broadcom HCPL-0900-500E provides direct parametric equivalence. NVE IL 710-3 and IL 710T-3E offer enhanced common mode transient immunity (100kV/µs) but operate at identical data rates. IL 710T-3E extends the upper operating temperature to 125°C and includes ROHS3 compliance. Both NVE parts utilize GMR technology matching the original design.

Q: Is the Skyworks SI8610AB-B-ISR suitable for high-speed applications?

A: No. The SI8610AB-B-ISR operates at 1Mbps data rate with 35ns propagation delay, significantly lower than the HCPL-0900-500 specification of 110MBd with 15ns propagation delay. This part is suitable only for low-speed isolation applications. Capacitive coupling technology differs from the GMR platform of other substitutes.

Q: What packaging considerations apply to these substitutes?

A: All substitutes use identical 8-SOIC (0.154", 3.90mm Width) surface mount packages. HCPL-0900-500, HCPL-0900-500E, and SI8610AB-B-ISR are supplied in tape and reel format. IL 710-3 packaging is unspecified. IL 710T-3E is supplied in tube format, requiring different handling and placement equipment considerations.

Q: Are there temperature range limitations with substitute parts?

A: HCPL-0900-500 and HCPL-0900-500E operate across -55°C to 125°C. IL 710-3 is limited to -40°C to 100°C. IL 710T-3E and SI8610AB-B-ISR extend to -40°C to 125°C. Applications requiring operation below -40°C must use the original Broadcom parts.

Q: Which substitute offers the best common mode transient immunity?

A: IL 710-3 and IL 710T-3E both provide 100kV/µs common mode transient immunity, compared to 15kV/µs for HCPL-0900-500 and HCPL-0900-500E. SI8610AB-B-ISR provides 35kV/µs. Enhanced CMTI reduces susceptibility to noise in high-speed switching environments.

Q: What is the moisture sensitivity impact of the SI8610AB-B-ISR?

A: SI8610AB-B-ISR carries MSL 2A rating (4 weeks shelf life in controlled humidity), compared to MSL 1 (unlimited) for all other substitutes. This requires stricter storage and handling protocols and shorter shelf life management in inventory systems.
