Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCPL-2631#300 is determined by strict equivalence across the following critical parameters:

• Manufacturer & Base Product Number: Both parts must be manufactured by Broadcom Limited and share the base product number HCPL-2631
• Electrical Specifications: Number of channels (2), isolation voltage (3750Vrms), CMTI (10kV/µs), output type (Open Collector, Schottky Clamped), output current (50 mA), and data rate (10MBd) must be identical
• Supply Voltage & Temperature Range: Operating voltage (4.5V ~ 5.5V) and temperature range (-40°C ~ 85°C) must match
• Package & Mounting: Both parts must use 8-SMD Gull Wing surface mount packaging

The HCPL-2631-300E meets all substitution criteria and is classified as a direct equivalent part.

Parameter Comparison

Engineering Selection Recommendations

Both HCPL-2631#300 and HCPL-2631-300E are active production parts from Broadcom Limited with identical electrical and mechanical specifications. The primary distinction is RoHS compliance status:

• HCPL-2631#300: RoHS non-compliant
• HCPL-2631-300E: ROHS3 Compliant

Selection between these parts should be based on regulatory requirements for your application. If RoHS3 compliance is mandated by design specifications, supply chain requirements, or end-market regulations, the HCPL-2631-300E is the appropriate choice. Both parts are REACH Unaffected and classified under ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Can HCPL-2631-300E be used as a direct replacement for HCPL-2631#300?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including isolation voltage, channel count, output type, data rate, and package configuration. The difference is RoHS compliance status only.

Q: What is the primary reason to substitute HCPL-2631#300 with HCPL-2631-300E?

A: RoHS3 compliance. If your application or supply chain requires RoHS-compliant components, HCPL-2631-300E is the appropriate selection.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use identical 8-SMD Gull Wing surface mount packaging with the same pin configuration and mechanical footprint.

Q: What is the isolation voltage rating for both parts?

A: Both HCPL-2631#300 and HCPL-2631-300E provide 3750Vrms isolation with 10kV/µs common mode transient immunity.

Q: Can these parts operate in the same temperature range?

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

Q: What is the maximum output current per channel?

A: Both parts support 50 mA maximum output current per channel with open collector, Schottky clamped outputs.
