HCPL-0931-500E Equivalent & Substitute Parts

Part Overview

The HCPL-0931-500E is a general purpose digital isolator manufactured by Broadcom Limited, featuring 2500Vrms isolation voltage and 2 channels in an 8-SOIC package. This component is currently active and widely used in applications requiring galvanic isolation with high common mode transient immunity (15kV/µs) and data rates up to 110MBd. Substitute parts are identified when design requirements allow for alternative isolation technologies, channel configurations, or performance specifications while maintaining functional compatibility within the application circuit.

Substitute Part Grouping Explanation

Substitute parts for the HCPL-0931-500E are grouped based on the following substitution criteria:

Parametric Equivalents maintain the same isolation voltage (2500Vrms), channel configuration (2 channels), CMTI (15kV/µs), and package (8-SOIC), with allowable variations in data rate and propagation delay within application tolerances.

Manufacturer Recommended Alternatives provide equivalent isolation voltage and channel count but may differ in isolation technology (GMR vs. Capacitive Coupling), data rate, CMTI, or operating temperature range. These parts are suitable when the application can accommodate the specified parameter variations.

Key Parameters for Substitution Determination:

• Isolation voltage (2500Vrms minimum required)
• Number of channels (2 channels required)
• Package type (8-SOIC form factor)
• Common mode transient immunity (15kV/µs minimum)
• Supply voltage range (3V ~ 5.5V compatibility)
• Operating temperature range (-55°C ~ 125°C preferred)

Parameter Comparison

Engineering Selection Recommendations

Broadcom GMR-Based Substitutes (HCPL-0900-500E, IL 611-3E, IL 611-3ETR7): These parts maintain GMR isolation technology and 2500Vrms isolation voltage. HCPL-0900-500E differs only in channel count (1 channel vs. 2), suitable for single-channel applications. IL 611-3E and IL 611-3ETR7 maintain 2-channel configuration but operate within -40°C to 85°C temperature range and support 100Mbps data rate. All three are ROHS3 compliant with MSL 1 rating.

Texas Instruments Capacitive Coupling Substitutes (ISO7321 Series, ISO7420FCCDR): ISO7321 variants (CD, CDR, FCD, FCDR) provide higher isolation voltage (3000Vrms) and superior CMTI (25kV/µs) using capacitive coupling technology. These parts support extended operating temperature to 125°C but operate at reduced data rates (25Mbps). ISO7420FCCDR offers intermediate performance with 2500Vrms isolation, 50Mbps data rate, and 25kV/µs CMTI. All Texas Instruments parts are ROHS3 compliant with MSL 2 rating (1 Year).

Selection Basis:

• All substitute parts maintain 8-SOIC package compatibility
• All parts are active products with ROHS3 compliance
• Substitution validity depends on application tolerance for data rate, propagation delay, temperature range, and isolation technology differences
• Inventory availability varies across part numbers and packaging options

Frequently Asked Questions (FAQ)

Q: Can HCPL-0900-500E replace HCPL-0931-500E in all applications? A: HCPL-0900-500E is a single-channel isolator versus the 2-channel HCPL-0931-500E. Substitution is valid only for applications requiring single-channel isolation with identical electrical specifications (2500Vrms, 110MBd, 15kV/µs CMTI, -55°C to 125°C).

Q: What are the key differences between GMR and Capacitive Coupling technologies in these isolators? A: The HCPL-0931-500E uses GMR technology with 110MBd data rate and 15kV/µs CMTI. Texas Instruments ISO7321 series uses Capacitive Coupling with 25Mbps data rate and 25kV/µs CMTI. Technology selection depends on application bandwidth and noise immunity requirements.

Q: Are IL 611-3E and IL 611-3ETR7 interchangeable? A: Both parts are functionally equivalent with identical electrical specifications (2500Vrms, 2 channels, 100Mbps, 15kV/µs CMTI, -40°C to 85°C). Differences exist only in packaging format (Tube vs. unspecified) and ECCN classification.

Q: Can ISO7420FCCDR be used as a direct replacement for HCPL-0931-500E? A: ISO7420FCCDR maintains 2500Vrms isolation and 2-channel configuration in 8-SOIC package but operates at 50Mbps data rate (vs. 110MBd) with 25kV/µs CMTI (vs. 15kV/µs). Substitution is valid only when application bandwidth requirements are satisfied by 50Mbps performance.

Q: What is the significance of MSL rating differences between parts? A: HCPL-0931-500E has MSL 1 (Unlimited shelf life). Texas Instruments parts have MSL 2 (1 Year shelf life). This affects storage and handling requirements but does not impact electrical performance or application compatibility.

Q: Do all substitute parts support the full -55°C to 125°C operating range? A: No. HCPL-0931-500E and ISO7321 series support -55°C to 125°C or -40°C to 125°C. IL 611-3E and IL 611-3ETR7 operate within -40°C to 85°C. Application temperature requirements determine valid substitutes.

Q: Are packaging variations (Cut Tape, Tape & Reel, Tube) electrically significant? A: Packaging format affects handling, storage, and supply chain logistics but does not alter electrical specifications or functional performance. Selection depends on assembly process requirements and inventory management.
