HCPL-091J-500 Digital Isolator Equivalent & Substitute Parts

Part Overview

The HCPL-091J-500 is a general purpose digital isolator manufactured by Broadcom Limited, featuring 2500Vrms isolation voltage, 4 channels, and 110MBd data rate in a 16-SOIC surface mount package. This component utilizes Giant Magnetoresistive (GMR) technology for signal isolation in applications requiring high common mode transient immunity (15kV/µs) and low propagation delay.

The HCPL-091J-500 is discontinued at DiGi Electronics, making identification of equivalent substitute parts essential for design continuity and procurement planning. Current inventory of 1100 pieces is available, but long-term availability is limited due to discontinued status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-091J-500 is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 2500Vrms (electrical isolation requirement)
• Number of Channels: 4 (functional requirement)
• Data Rate: 110MBd (signal bandwidth requirement)
• Common Mode Transient Immunity: 15kV/µs (transient performance requirement)
• Package / Case: 16-SOIC (0.154", 3.90mm Width) (mechanical and thermal requirement)
• Voltage - Supply: 3V ~ 5.5V (power supply compatibility)
• Operating Temperature: -55°C ~ 125°C (environmental requirement)
• Technology: GMR (Giant Magnetoresistive) (functional technology)

The HCPL-091J-500E meets all these parameters identically and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-091J-500E is the direct parametric equivalent substitute for the HCPL-091J-500. All electrical, mechanical, and thermal specifications are identical. The primary distinction is product status and compliance:

• HCPL-091J-500E is currently active with 3200 pieces in stock, providing superior long-term availability compared to the discontinued HCPL-091J-500.
• HCPL-091J-500E achieves ROHS3 compliance, whereas the HCPL-091J-500 is RoHS non-compliant. This compliance difference may be relevant for applications subject to RoHS regulations.
• Both parts share identical REACH and ECCN classifications (REACH Unaffected, EAR99).

For new designs or procurement requiring long-term component availability, the HCPL-091J-500E is the appropriate selection. For existing designs currently using HCPL-091J-500, direct substitution with HCPL-091J-500E is electrically and mechanically valid without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can HCPL-091J-500E directly replace HCPL-091J-500 in existing designs?

A: Yes. The HCPL-091J-500E is a parametric equivalent with identical electrical specifications, pin configuration, and package dimensions. No circuit modifications are required for direct substitution.

Q: What is the difference between HCPL-091J-500 and HCPL-091J-500E?

A: The parts are electrically and mechanically identical. The primary differences are: (1) HCPL-091J-500 is discontinued; HCPL-091J-500E is active; (2) HCPL-091J-500E is ROHS3 compliant while HCPL-091J-500 is RoHS non-compliant; (3) HCPL-091J-500E has higher inventory availability (3200 pieces vs. 1100 pieces).

Q: Are there packaging differences between these parts?

A: The HCPL-091J-500 is supplied in standard packaging. The HCPL-091J-500E is available in Cut Tape (CT) and Digi-Reel® packaging options. Both use the identical 16-SOIC (0.154", 3.90mm Width) package. Packaging format does not affect electrical or mechanical compatibility.

Q: What isolation voltage does this digital isolator provide?

A: Both the HCPL-091J-500 and HCPL-091J-500E provide 2500Vrms isolation voltage with 15kV/µs common mode transient immunity.

Q: Is this component suitable for high-speed applications?

A: Yes. The HCPL-091J-500 and HCPL-091J-500E support 110MBd data rate with 15ns maximum propagation delay and 3ns maximum pulse width distortion, making them suitable for high-speed digital isolation applications.

Q: What supply voltage range is required?

A: Both parts operate with a supply voltage range of 3V to 5.5V, providing compatibility with standard 3.3V and 5V logic systems.
