Engineering Selection Recommendations

5000Vrms Isolation Requirement: Applications requiring 5000Vrms isolation voltage must use ACPL-W302-500E, ACPL-W345-500E, ACPL-W340-500E, or ACPL-W347-500E. The ACPL-P series (ACPL-P340-500E, ACPL-P345-500E, ACPL-P347-500E) provide 3750Vrms isolation and are not suitable for 5000Vrms specifications.

Output Current Demand: The ACPL-W302-500E delivers 400mA peak output current. Applications requiring 800mA to 1A peak output current must transition to ACPL-W345-500E, ACPL-W340-500E, ACPL-W347-500E, or equivalent ACPL-P series parts.

Propagation Delay Specifications: The ACPL-W302-500E exhibits 700ns maximum propagation delay. Applications with tighter timing requirements (≤200ns) can use ACPL-W340-500E or ACPL-P340-500E. Applications requiring ≤120ns propagation delay must use ACPL-W345-500E, ACPL-W347-500E, ACPL-P345-500E, or ACPL-P347-500E.

Common Mode Transient Immunity: The ACPL-W302-500E provides 10kV/µs immunity. Applications requiring 35kV/µs or higher must use ACPL-W340-500E, ACPL-W345-500E, ACPL-W347-500E, or equivalent ACPL-P series parts.

Output Supply Voltage Range: The ACPL-W302-500E operates with 10V to 30V output supply. ACPL-W345-500E and ACPL-P345-500E operate within 10V to 20V range. ACPL-W340-500E, ACPL-W347-500E, ACPL-P340-500E, and ACPL-P347-500E operate within 15V to 30V range. Verify output supply voltage compatibility before substitution.

Regulatory and Compliance Status: All parts maintain active product status, ROHS3 compliance, CSA/UR approvals, and identical ECCN/HTSUS classifications. All parts carry MSL Level 1 (Unlimited) moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can ACPL-P340-500E, ACPL-P345-500E, or ACPL-P347-500E replace ACPL-W302-500E in a 5000Vrms isolation application?

A: No. The ACPL-P series provides 3750Vrms isolation, which does not meet 5000Vrms isolation requirements. Only ACPL-W series parts (ACPL-W345-500E, ACPL-W340-500E, ACPL-W347-500E) maintain 5000Vrms isolation matching the original specification.

Q: What is the primary advantage of ACPL-W345-500E and ACPL-W347-500E over ACPL-W302-500E?

A: Both parts provide 5000Vrms isolation with significantly improved performance: 120ns and 110ns maximum propagation delay respectively (versus 700ns), 50kV/µs common mode transient immunity (versus 10kV/µs), and 1A peak output current (versus 400mA). Rise and fall times are reduced to 8ns typical.

Q: Are there packaging differences between substitute parts?

A: ACPL-W302-500E is supplied in Tape & Reel (TR) packaging. ACPL-W340-500E and ACPL-P340-500E are supplied in Cut Tape (CT) & Digi-Reel® packaging. ACPL-W345-500E, ACPL-W347-500E, ACPL-P345-500E, and ACPL-P347-500E are supplied in Tape & Reel (TR) packaging. All parts use identical 6-SOIC form factor.

Q: What output supply voltage range must be verified when substituting ACPL-W302-500E?

A: The original part operates with 10V to 30V output supply. ACPL-W345-500E and ACPL-P345-500E operate within 10V to 20V. ACPL-W340-500E, ACPL-W347-500E, ACPL-P340-500E, and ACPL-P347-500E operate within 15V to 30V. Confirm your application's output supply voltage falls within the substitute part's specified range.

Q: Can ACPL-W302-500E be used in applications where ACPL-W345-500E is specified?

A: No. ACPL-W345-500E is specified for applications requiring 1A peak output current, 120ns propagation delay, and 50kV/µs common mode transient immunity. ACPL-W302-500E provides only 400mA peak output current and 700ns propagation delay, which do not meet these specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (ACPL-W345-500E, ACPL-W340-500E, ACPL-W347-500E, ACPL-P340-500E, ACPL-P345-500E, ACPL-P347-500E) maintain ROHS3 compliance, CSA/UR approvals, and identical regulatory classifications as the original ACPL-W302-500E.
