ACPL-W302-560E Equivalent & Substitute Parts

Part Overview

The ACPL-W302-560E is a 400mA gate driver optical coupler manufactured by Broadcom Limited, providing 5000Vrms isolation in a 6-SO surface mount package. This component is designed for high-voltage gate driving applications requiring galvanic isolation between control and power circuits. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts become necessary when addressing application-specific requirements such as higher output current capacity, improved propagation delay characteristics, or enhanced common mode transient immunity that may exceed the original specification.

Substitute Part Grouping Explanation

The ACPL-P340-560E qualifies as a substitute based on the following criteria:

Maintained Compatibility Parameters:

Single-channel optical coupling architecture
6-SO package form factor (surface mount)
Broadcom Limited manufacturer ecosystem
RoHS3 compliance and CSA/IEC/EN/DIN/UR certifications
Unlimited moisture sensitivity level (MSL 1)

Substitution Logic: The ACPL-P340-560E operates within acceptable electrical parameter ranges for gate driver applications. While isolation voltage is reduced from 5000Vrms to 3750Vrms, this remains suitable for applications not requiring the full 5000Vrms specification. The substitute provides superior performance in propagation delay (200ns vs. 700ns), common mode transient immunity (35kV/µs vs. 10kV/µs), and output current capacity (1A vs. 400mA), making it applicable to designs with tighter timing requirements or higher gate drive current demands.

Engineering Selection Recommendations

Both ACPL-W302-560E and ACPL-P340-560E maintain Active product status with identical regulatory compliance (RoHS3, CSA, IEC/EN/DIN, UR certifications). Selection between these parts depends on isolation voltage requirements and performance specifications:

ACPL-W302-560E is appropriate for applications requiring 5000Vrms isolation specification or where the 10kV/µs common mode transient immunity threshold is sufficient.

ACPL-P340-560E is appropriate for applications where 3750Vrms isolation is acceptable and where improved propagation delay (200ns), higher common mode transient immunity (35kV/µs), or increased output current capacity (1A) provide design advantages. The reduced package width (6.80mm vs. 7.50mm) may offer PCB layout benefits in space-constrained designs.

Both parts are manufactured by Broadcom Limited and carry equivalent regulatory approvals, ensuring consistent supply chain qualification and documentation requirements.

Frequently Asked Questions (FAQ)

Q: Can ACPL-P340-560E directly replace ACPL-W302-560E in existing designs?

A: Direct replacement is possible only if the application does not require 5000Vrms isolation. The ACPL-P340-560E provides 3750Vrms isolation. Verify that your isolation voltage requirement does not exceed 3750Vrms before substitution. Both parts use identical 6-SO package technology and surface mount configuration.

Q: What are the key performance differences between these parts?

A: The ACPL-P340-560E provides superior propagation delay (200ns vs. 700ns), higher common mode transient immunity (35kV/µs vs. 10kV/µs), and greater output current capacity (1A vs. 400mA). The ACPL-W302-560E provides higher isolation voltage (5000Vrms vs. 3750Vrms).

Q: Are there package compatibility concerns?

A: Both parts use 6-SO surface mount packages. The ACPL-P340-560E has a slightly narrower width (6.80mm vs. 7.50mm). Verify PCB footprint compatibility with your design. The minimum output supply voltage differs: ACPL-W302-560E operates from 10V, while ACPL-P340-560E requires 15V minimum.

Q: Do both parts have identical certifications?

A: Yes. Both ACPL-W302-560E and ACPL-P340-560E carry CSA, IEC/EN/DIN, and UR approvals, with RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Q: Which part should I select for new designs?

A: Selection depends on isolation voltage requirements. If 3750Vrms isolation is acceptable, the ACPL-P340-560E offers performance advantages in propagation delay and output current. If 5000Vrms isolation is mandatory, use ACPL-W302-560E.
