Key Parameters

Substitute Part Grouping Explanation

Substitution for the HCPL-2631#520 is determined by the following critical electrical and mechanical parameters:

• Number of Channels: 2 channels required
• Voltage - Isolation: 5000Vrms minimum
• Common Mode Transient Immunity: 10kV/µs minimum
• Output Type: Open Collector, Schottky Clamped configuration
• Data Rate: 10MBd minimum
• Package / Case: 8-SMD, Gull Wing form factor
• Voltage - Supply: 4.5V ~ 5.5V compatibility
• Operating Temperature Range: -40°C ~ 85°C

The HCPL-2631-520E meets all these criteria and is classified as a direct manufacturer substitute. This part maintains identical functional specifications while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-2631-520E is the direct substitute for the HCPL-2631#520. Both parts are manufactured by Broadcom Limited and maintain identical electrical and mechanical specifications across all critical parameters. The HCPL-2631-520E offers two significant advantages:

1. Product Status: The HCPL-2631-520E is currently active in production, ensuring long-term availability and supply chain continuity.

2. Compliance: The HCPL-2631-520E is ROHS3 compliant, whereas the original part is RoHS non-compliant. This compliance improvement is relevant for applications subject to RoHS regulations.

Both parts share the same base product number (HCPL-2631) and are functionally interchangeable in circuit designs. The HCPL-2631-520E is supplied in Tape & Reel packaging, which is standard for production environments.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-2631-520E be used as a direct replacement for the HCPL-2631#520?

A: Yes. Both parts are manufactured by Broadcom Limited and maintain identical electrical specifications, including isolation voltage, CMTI, data rate, propagation delay, and output characteristics. The package and pin configuration are identical (8-SMD, Gull Wing).

Q: What is the difference between HCPL-2631#520 and HCPL-2631-520E?

A: The primary differences are product status and compliance. The HCPL-2631-520E is currently active in production and ROHS3 compliant, while the HCPL-2631#520 is discontinued and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any differences in current ratings between these parts?

A: The output current per channel is 50 mA for both parts. The DC forward current specification differs slightly (15mA maximum for HCPL-2631#520 versus 20mA maximum for HCPL-2631-520E), but this parameter relates to the LED input stage and does not affect output stage compatibility.

Q: What packaging options are available?

A: The HCPL-2631-520E is supplied in Tape & Reel (TR) packaging, which is standard for automated assembly. The original HCPL-2631#520 packaging specification was not defined in the available data.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both parts operate across the identical temperature range of -40°C to 85°C.
