HCPL-9031-500 Equivalent & Substitute Parts

Part Overview

The HCPL-9031-500 is a general purpose digital isolator manufactured by Broadcom Limited, featuring 2500Vrms isolation voltage, 2 channels, and 110MBd data rate with 15kV/µs common mode transient immunity. The device is packaged in 8-SMD, Gull Wing configuration and operates across -55°C to 125°C temperature range.

This part is discontinued at DiGi Electronics, necessitating identification of equivalent alternatives that maintain functional compatibility while meeting current procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are classified into two categories based on functional equivalence:

Direct Substitute (Identical Electrical & Mechanical Specifications):

• HCPL-9031-500E: Maintains all electrical parameters, isolation voltage, channel count, data rate, and timing specifications identical to the main part. Differs only in packaging format (Tape & Reel vs. bulk) and RoHS compliance status (ROHS3 Compliant vs. non-compliant).

Parametric Equivalents (Reduced Channel Count):

• HCPL-9000-500 and HCPL-9000-500E: Share identical electrical performance parameters including isolation voltage (2500Vrms), data rate (110MBd), CMTI (15kV/µs), propagation delay, and supply voltage range. Primary difference is single channel configuration versus dual channel. These parts are suitable for applications requiring only one isolation channel while maintaining all timing and electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Dual Channel Requirement): Select HCPL-9031-500E when the application requires two isolation channels with identical electrical performance to the original HCPL-9031-500. This part is actively available and meets ROHS3 compliance requirements, making it the preferred choice for new designs and ongoing production.

For Single Channel Applications: HCPL-9000-500E is suitable for applications requiring only one isolation channel. This part maintains all critical electrical parameters (isolation voltage, data rate, CMTI, timing specifications) while offering active product status and ROHS3 compliance. HCPL-9000-500 provides equivalent electrical performance but with RoHS non-compliant status.

Compliance Considerations: Parts designated with "-500E" suffix (HCPL-9031-500E and HCPL-9000-500E) carry ROHS3 compliance certification. Non-suffixed variants maintain RoHS non-compliant status. Selection should align with regulatory requirements for the target application and market.

Frequently Asked Questions (FAQ)

Q: Can HCPL-9031-500E directly replace HCPL-9031-500 in existing designs? A: Yes. HCPL-9031-500E maintains identical electrical specifications, channel count, timing parameters, and package configuration. The primary differences are active product status and ROHS3 compliance. No circuit modifications are required.

Q: What is the key difference between HCPL-9031-500 and HCPL-9000-500? A: The HCPL-9031-500 provides 2 isolation channels while HCPL-9000-500 provides 1 channel. All other electrical parameters including isolation voltage, data rate, CMTI, propagation delay, and supply voltage are identical. Channel count determines suitability for the application.

Q: Are the HCPL-9000-500 and HCPL-9000-500E interchangeable? A: Yes, from an electrical and functional standpoint. Both parts are single-channel isolators with identical performance specifications. The difference is RoHS compliance status: HCPL-9000-500E is ROHS3 compliant while HCPL-9000-500 is not.

Q: Does packaging format affect electrical performance? A: No. Tape & Reel (TR) packaging is a distribution format only and does not alter electrical characteristics or performance. Selection between bulk and Tape & Reel packaging depends on procurement and assembly requirements.

Q: What certifications apply to these digital isolators? A: All parts carry REACH Unaffected and EAR99 ECCN designations. RoHS compliance varies by part number suffix: "-500E" variants are ROHS3 compliant; non-suffixed variants are RoHS non-compliant. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all variants.
