Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCNW2601 are identified based on electrical and mechanical parameter equivalence. The critical parameters determining substitution eligibility are:

• Isolation voltage: 5000Vrms
• Number of channels: 1
• Output configuration: Open Collector, Schottky Clamped
• Data rate: 10MBd
• Common mode transient immunity: 10kV/µs minimum
• Package type: 8-DIP through-hole
• Supply voltage range: 4.5V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C

The HCNW2601-000E variant meets all electrical and mechanical specifications of the base HCNW2601, differing only in packaging format (tube versus standard packaging) and RoHS compliance status. This variant maintains full functional and pin-level compatibility.

Parameter Comparison

Engineering Selection Recommendations

The HCNW2601-000E serves as a direct functional substitute for the HCNW2601, with identical electrical performance and mechanical compatibility. The primary distinction is regulatory compliance: the HCNW2601-000E carries ROHS3 certification, making it the appropriate selection for applications subject to RoHS directives or customer specifications requiring RoHS compliance. Both variants maintain active product status and are manufactured by Broadcom Limited with equivalent reliability characteristics. Selection between these parts should be based on regulatory requirements and packaging format preferences (tube versus standard packaging).

Frequently Asked Questions (FAQ)

Q: Can HCNW2601-000E replace HCNW2601 in existing designs?

A: Yes. The HCNW2601-000E is electrically and mechanically identical to the HCNW2601. Both devices feature the same isolation voltage, data rate, output configuration, and pin assignment. Direct substitution is supported without circuit modification.

Q: What is the difference between HCNW2601 and HCNW2601-000E?

A: The primary differences are packaging format and RoHS compliance status. The HCNW2601-000E is supplied in tube packaging and carries ROHS3 certification, while the base HCNW2601 is RoHS non-compliant. All electrical and functional specifications are identical.

Q: Which variant should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS compliance or subject to RoHS directives, specify HCNW2601-000E. For applications without RoHS requirements, either variant is acceptable based on availability and packaging preference.

Q: Are there any thermal or reliability differences between these parts?

A: No. Both variants operate across the same temperature range (-40°C to 85°C) and share identical electrical characteristics, propagation delays, and output specifications. Reliability and thermal performance are equivalent.

Q: What is the significance of the 8-DIP package format?

A: The 8-DIP (0.400", 10.16mm) package is a standard through-hole format suitable for breadboard prototyping, PCB socket mounting, and conventional assembly processes. Both substitute parts use this identical package, ensuring mechanical interchangeability.

Q: Can these parts be used in high-speed digital isolation applications?

A: Yes. With a 10MBd data rate, 100ns maximum propagation delay, and 10kV/µs common mode transient immunity, both HCNW2601 and HCNW2601-000E are suitable for high-speed digital isolation in industrial and communication applications.
