Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCPL-3000-000E is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 8-DIP (0.300", 7.62mm) through-hole package to ensure direct board-level compatibility without layout modifications.

Channel Configuration: Single-channel operation is required; the substitute must maintain 1-channel architecture.

Isolation Voltage: The HCPL-3000-000E provides 5000Vrms isolation. The substitute HCPL-3120-000E operates at 3750Vrms, which represents a reduction in isolation capability. This substitution is valid only in applications where the lower isolation voltage meets system requirements.

Input Type: DC input operation must be maintained.

Output Current Capability: The HCPL-3000-000E delivers 500mA to 600mA per channel. The HCPL-3120-000E provides 2A continuous output current with 2.5A peak capability, representing a significant increase in output drive strength.

Supply Voltage Range: The HCPL-3000-000E operates from 5.4V to 13V. The HCPL-3120-000E requires 15V to 30V output supply, necessitating verification of available supply rails in the target application.

Propagation Delay and Timing: The HCPL-3000-000E exhibits 5µs maximum propagation delay. The HCPL-3120-000E provides 500ns maximum propagation delay, representing substantially faster switching performance.

Parameter Comparison

Engineering Selection Recommendations

The HCPL-3120-000E is the manufacturer-recommended substitute for the obsolete HCPL-3000-000E. Both components are manufactured by Broadcom Limited and share identical 8-DIP package geometry, enabling direct board-level replacement without layout modification.

The HCPL-3120-000E carries Active product status with RoHS3 compliance, ensuring long-term availability and regulatory alignment. The component holds dual approval from CSA and UR, compared to UR approval for the original part, providing expanded certification coverage.

Critical design considerations for substitution:

Isolation Voltage Reduction: The substitute operates at 3750Vrms versus the original 5000Vrms. Substitution is valid only when system isolation requirements do not exceed 3750Vrms.

Supply Voltage Requirement: The HCPL-3120-000E requires 15V to 30V output supply, whereas the original operates from 5.4V to 13V. Verification of available supply rails is mandatory before implementation.

Performance Enhancement: The HCPL-3120-000E delivers substantially improved timing performance with 500ns propagation delay versus 5µs, and increased output current capability of 2A continuous (2.5A peak) versus 500-600mA. These enhancements are compatible with legacy circuit designs.

Temperature Range Expansion: Operating temperature range extends from -40°C to 100°C, providing broader environmental coverage than the original -20°C to 80°C specification.

Frequently Asked Questions (FAQ)

Q: Can the HCPL-3120-000E be used as a direct replacement for the HCPL-3000-000E?

A: Direct board-level replacement is possible due to identical 8-DIP package geometry. However, three design parameters require verification: isolation voltage (3750Vrms vs. 5000Vrms), output supply voltage range (15V-30V vs. 5.4V-13V), and application timing requirements. Substitution is valid only when all three parameters are compatible with system specifications.

Q: What is the primary difference in isolation voltage between these parts?

A: The HCPL-3000-000E provides 5000Vrms isolation, while the HCPL-3120-000E provides 3750Vrms isolation. This 1250Vrms reduction must be evaluated against system isolation requirements. If the application requires 5000Vrms isolation, the HCPL-3120-000E is not suitable.

Q: Does the HCPL-3120-000E require circuit modifications?

A: The output supply voltage requirement differs significantly. The HCPL-3120-000E requires 15V to 30V, whereas the original operates from 5.4V to 13V. If the existing circuit provides only 5.4V to 13V output supply, additional power supply circuitry is required. The identical 8-DIP pinout eliminates socket-level modifications.

Q: What are the timing performance improvements?

A: The HCPL-3120-000E provides 500ns maximum propagation delay compared to 5µs for the original part, representing a 10-fold improvement. Rise and fall times are also improved to 100ns. These enhancements are backward-compatible with legacy designs that tolerate faster switching.

Q: Is the HCPL-3120-000E suitable for high-temperature applications?

A: Yes. The HCPL-3120-000E operates from -40°C to 100°C, compared to -20°C to 80°C for the original. This extended range supports applications requiring operation at elevated temperatures.

Q: What certifications does the HCPL-3120-000E carry?

A: The HCPL-3120-000E holds CSA and UR approvals, compared to UR approval for the original part. The component is RoHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: Can I use the HCPL-3120-000E if my system requires 5000Vrms isolation?

A: No. The HCPL-3120-000E provides only 3750Vrms isolation. If 5000Vrms isolation is a system requirement, this substitute is not suitable. Alternative components with 5000Vrms or higher isolation must be evaluated.
