Frequently Asked Questions (FAQ)

Q: Can the ACPL-K73A-500E directly replace the ACPL-K73A-560E in existing designs?

A: Yes. Both parts share identical electrical parameters including isolation voltage, current transfer ratio, output voltage, output current, and operating temperature range. The physical package and mounting type are also identical, enabling direct PCB-level substitution without circuit modification.

Q: Are there differences in isolation voltage or current handling between these parts?

A: No. Both the ACPL-K73A-560E and ACPL-K73A-500E provide 5000Vrms isolation, support 60mA output current per channel, and maintain identical current transfer ratio specifications across the full operating range.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant with MSL rating of 1 (Unlimited) and REACH unaffected status. They carry identical ECCN and HTSUS classifications.

Q: What is the difference between the ACPL-K73A-560E and ACPL-K73A-500E part numbers?

A: The part numbers differ in the suffix designation (560E versus 500E), but this difference does not reflect changes in electrical performance or mechanical form factor. Both parts are based on the ACPL-K73 platform and are manufactured by Broadcom Limited.

Q: Are there any temperature or environmental operating differences?

A: No. Both parts operate across the identical temperature range of -40°C to 105°C and maintain the same moisture sensitivity level classification.
