Substitute Part Grouping Explanation

Substitution for the HCPL-261N#360 is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 3750Vrms (mandatory match)
• Number of Channels: 1 channel (mandatory match)
• Output Configuration: Open Collector, Schottky Clamped (mandatory match)
• Data Rate: 10MBd (mandatory match)
• Common Mode Transient Immunity: 1kV/µs minimum (mandatory match)
• Package Type: 8-SMD, Gull Wing (mandatory match)
• Supply Voltage Range: 4.5V ~ 5.5V (mandatory match)
• Operating Temperature Range: -40°C ~ 85°C (mandatory match)

The HCPL-261N-360E is a direct manufacturer equivalent from Broadcom Limited, differing only in packaging format (Tube vs. standard packaging) and product status (Active vs. Discontinued). All electrical and mechanical specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-261N-360E is the primary substitute for the discontinued HCPL-261N#360. Both parts are manufactured by Broadcom Limited and maintain identical electrical and mechanical specifications across all critical parameters. The HCPL-261N-360E offers the advantage of active product status, ensuring continued availability and supply chain reliability.

The HCPL-261N-360E provides improved environmental compliance with ROHS3 certification, compared to the non-compliant status of the original part. This upgrade is beneficial for applications subject to RoHS regulations. Both parts share identical isolation voltage, data rate, output configuration, and thermal operating range, confirming direct functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can HCPL-261N-360E be used as a direct replacement for HCPL-261N#360?

A: Yes. The HCPL-261N-360E is electrically and mechanically identical to the HCPL-261N#360. All critical parameters including isolation voltage (3750Vrms), data rate (10MBd), output type (Open Collector, Schottky Clamped), and package configuration (8-SMD, Gull Wing) are equivalent. The primary difference is product status (Active vs. Discontinued) and RoHS compliance level.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by matching: isolation voltage (3750Vrms), number of channels (1), output configuration (Open Collector, Schottky Clamped), data rate (10MBd), common mode transient immunity (1kV/µs minimum), package type (8-SMD, Gull Wing), supply voltage range (4.5V ~ 5.5V), and operating temperature range (-40°C ~ 85°C).

Q: Does the HCPL-261N-360E have different packaging?

A: The HCPL-261N-360E is supplied in Tube packaging, whereas the original HCPL-261N#360 had standard packaging. The physical component package (8-SMD, Gull Wing) and pin configuration remain identical, making it suitable for the same PCB layouts and assembly processes.

Q: Is the HCPL-261N-360E RoHS compliant?

A: Yes. The HCPL-261N-360E is ROHS3 compliant, whereas the original HCPL-261N#360 is RoHS non-compliant. This improvement makes the substitute part suitable for applications and markets requiring RoHS certification.

Q: Are there any performance differences between these parts?

A: No. Both parts maintain identical electrical performance specifications including propagation delay (100ns maximum for both tpLH and tpHL), rise/fall times (42ns/12ns typical), forward voltage (1.3V typical), and output current capability (50mA per channel).
