HCNW2611 Equivalent & Substitute Parts

Part Overview

The HCNW2611 is a logic output optoisolator manufactured by Broadcom Limited, designed for high-speed digital isolation applications. This 5000Vrms isolation device features open collector output with Schottky clamping, supporting data rates up to 10MBd with 15kV/µs common mode transient immunity. The component is housed in an 8-DIP through-hole package and operates across the industrial temperature range of -40°C to 85°C. As an active product with established supply availability, alternative packaging configurations and compliance variants are available to meet specific procurement and regulatory requirements.

Key Parameters

Substitute Part Grouping Explanation

The HCNW2611-000E qualifies as a direct substitute based on identical electrical and mechanical specifications. Substitution eligibility is determined by the following critical parameters:

• Number of Channels: 1 (must match)
• Voltage - Isolation: 5000Vrms (must match)
• Common Mode Transient Immunity: 15kV/µs (must match)
• Output Type: Open Collector, Schottky Clamped (must match)
• Current - Output / Channel: 50 mA (must match)
• Data Rate: 10MBd (must match)
• Package / Case: 8-DIP (0.400", 10.16mm) (must match)
• Mounting Type: Through Hole (must match)

The HCNW2611-000E differs only in packaging configuration (Tube versus standard packaging) and RoHS compliance status, with no impact on functional performance or electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both HCNW2611 and HCNW2611-000E are active products from Broadcom Limited with identical electrical and mechanical specifications. Selection between these parts is determined by regulatory compliance requirements:

• HCNW2611: Select for applications where RoHS compliance is not mandated or where existing non-compliant component inventories are acceptable.
• HCNW2611-000E: Select for applications requiring ROHS3 compliance or for new designs subject to RoHS regulations. This variant is supplied in Tube packaging and maintains full functional equivalence.

Both parts carry REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity rating, indicating no special handling requirements during storage or assembly.

Frequently Asked Questions (FAQ)

Q: Can HCNW2611-000E be used as a direct replacement for HCNW2611 in existing designs?

A: Yes. The HCNW2611-000E is electrically and mechanically identical to the HCNW2611. All electrical parameters, timing characteristics, isolation voltage, output current, and package dimensions are equivalent. The only differences are packaging format (Tube) and RoHS compliance status.

Q: What is the primary reason to select HCNW2611-000E over HCNW2611?

A: The HCNW2611-000E is ROHS3 compliant, making it the required choice for applications subject to RoHS regulations or for procurement into regions with RoHS mandates.

Q: Are there any performance differences between these two part numbers?

A: No. Both parts deliver identical performance across all electrical specifications, including isolation voltage (5000Vrms), data rate (10MBd), common mode transient immunity (15kV/µs), output current (50mA), and propagation delay (100ns maximum).

Q: What is the difference in packaging between HCNW2611 and HCNW2611-000E?

A: The HCNW2611-000E is supplied in Tube packaging, while the standard HCNW2611 uses alternative packaging. Both maintain the same 8-DIP (0.400", 10.16mm) physical form factor and through-hole mounting configuration.

Q: Do both parts require special handling during assembly?

A: No. Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture sensitivity precautions are required during storage, handling, or assembly.

Q: Are there any supply or availability considerations when selecting between these parts?

A: Both parts are active products with established supply. Inventory availability may vary by supplier and region. Verify current stock levels with your component distributor.
