Substitute Part Grouping Explanation
Substitution of the HCPL-0314-560E is based on the following critical parameters:
- Isolation Voltage: 3750Vrms minimum requirement for galvanic separation
- Channel Configuration: Single-channel gate driver topology
- Technology: Optical coupling isolation method
- Output Current Capability: Peak output current of 600mA or greater
- Output Supply Voltage Range: Compatibility with 10V ~ 30V supply envelope
- Product Status: Active manufacturing status with current availability
- Compliance: RoHS3 and regulatory approvals (CSA, IEC/EN/DIN, UR)
The ACPL-P340-560E meets these substitution criteria with enhanced performance characteristics in propagation delay, common mode transient immunity, and output current capacity.

Engineering Selection Recommendations
Both the HCPL-0314-560E and ACPL-P340-560E are active products from Broadcom Limited with identical isolation voltage ratings and single-channel gate driver architecture. Both devices maintain RoHS3 compliance and unlimited moisture sensitivity classification, ensuring regulatory and environmental compatibility.
The ACPL-P340-560E provides superior performance in propagation delay (200ns versus 700ns), common mode transient immunity (35kV/µs versus 25kV/µs), and output current capacity (1A versus 600mA). These enhancements support applications requiring faster switching response and higher gate drive current.
Package geometry differs between the two devices: the HCPL-0314-560E uses an 8-SOIC form factor while the ACPL-P340-560E uses a 6-SOIC stretched package. Output supply voltage minimum specification for the ACPL-P340-560E is 15V, compared to 10V for the HCPL-0314-560E. Applications operating below 15V output supply require the HCPL-0314-560E.
Frequently Asked Questions (FAQ)
Q: Can the ACPL-P340-560E directly replace the HCPL-0314-560E in existing designs?
A: Direct replacement requires verification of three factors: PCB layout compatibility with the different package geometries (8-SOIC versus 6-SOIC stretched), output supply voltage minimum of 15V for the ACPL-P340-560E, and confirmation that the enhanced performance characteristics do not introduce timing-related issues in the application circuit.
Q: What is the primary functional difference between these two gate drivers?
A: Both devices provide identical 3750Vrms isolation and single-channel gate drive functionality. The ACPL-P340-560E offers faster propagation delay (200ns versus 700ns), higher output current capacity (1A versus 600mA), and improved common mode transient immunity (35kV/µs versus 25kV/µs).
Q: Are there package compatibility constraints?
A: Yes. The HCPL-0314-560E uses an 8-SOIC package (3.90mm width) while the ACPL-P340-560E uses a 6-SOIC stretched package (6.80mm width). PCB footprint redesign is required for substitution.
Q: What output supply voltage range applies to each device?
A: The HCPL-0314-560E operates with 10V ~ 30V output supply. The ACPL-P340-560E requires 15V ~ 30V output supply. Applications with output supply below 15V must use the HCPL-0314-560E.
Q: Do both devices share the same regulatory approvals?
A: Yes. Both the HCPL-0314-560E and ACPL-P340-560E carry CSA, IEC/EN/DIN, and UR approvals with RoHS3 compliance and REACH unaffected status.
