Frequently Asked Questions (FAQ)
Q: Can HCPL-061A-560E be used as a direct replacement for HCPL-061A#560?
A: Yes. Both parts share identical electrical specifications, including isolation voltage, output configuration, data rate, and timing characteristics. The 8-SOIC package dimensions are equivalent, allowing direct PCB substitution without layout modification.
Q: What is the difference between HCPL-061A#560 and HCPL-061A-560E?
A: The primary differences are product status, packaging format, and compliance certification. HCPL-061A-560E is an active product supplied in Tape & Reel format with ROHS3 compliance, while HCPL-061A#560 is discontinued and supplied in bulk packaging without RoHS certification.
Q: Are there compatibility concerns with the packaging change from bulk to Tape & Reel?
A: No. Tape & Reel packaging is standard for automated assembly and provides superior handling and storage characteristics. The component itself remains unchanged; only the delivery format differs.
Q: What isolation voltage does this optoisolator provide?
A: The HCPL-061A#560 and HCPL-061A-560E both provide 3750Vrms isolation, suitable for applications requiring high-voltage galvanic separation between input and output circuits.
Q: What is the maximum data rate supported?
A: Both parts support a maximum data rate of 10MBd with propagation delays of 100ns maximum for both rising and falling edges.
