Replacement verdict
Compatible functional replacement candidate
The ACPL-C79B-000E and ACPL-C780-060E are functionally compatible isolated amplifier components sharing the same package, isolation architecture, and signal chain topology, making the ACPL-C79B-000E a viable replacement candidate for the ACPL-C780-060E in most designs. However, designers must validate the tighter gain tolerance and extended operating temperature range of the ACPL-C79B-000E against their specific application requirements before committing to a drop-in substitution.

Frequently asked questions
What are the key differences between the ACPL-C79B-000E and ACPL-C780-060E isolation amplifiers?
The ACPL-C79B-000E is a precision optically isolated amplifier with ±0.5% gain tolerance and 200 kHz bandwidth, while the ACPL-C780-060E is a lower-cost isolated amplifier with ±1% gain tolerance and 100 kHz bandwidth. Both provide 5 kVrms isolation and are housed in 8-pin DIP packages, but the C79B offers higher accuracy and wider bandwidth for precision current sensing applications.
Are the ACPL-C79B-000E and ACPL-C780-060E pin-compatible?
Yes, both devices are offered in the same 8-pin DIP package with identical pinout configurations, allowing for potential drop-in replacement in existing designs. However, designers must verify that the reduced bandwidth and gain accuracy of the ACPL-C780-060E meet system requirements before substituting.
What is the isolation voltage rating for both the ACPL-C79B-000E and ACPL-C780-060E?
Both the ACPL-C79B-000E and ACPL-C780-060E are rated for 5 kVrms isolation for 1 minute per UL 1577, and both carry IEC/EN/DIN EN 60747-5-5 approval with working voltage specifications. These ratings make both suitable for industrial motor drive and power conversion applications requiring reinforced isolation.
Which part offers better gain accuracy for precision current sensing?
The ACPL-C79B-000E offers superior gain accuracy with ±0.5% maximum gain error at 25°C, compared to ±1% for the ACPL-C780-060E. For applications requiring tight current measurement tolerances, such as servo motor control or precision power monitoring, the ACPL-C79B-000E is the more appropriate choice.
What is the bandwidth difference between the ACPL-C79B-000E and ACPL-C780-060E?
The ACPL-C79B-000E provides a nominal -3 dB bandwidth of 200 kHz, while the ACPL-C780-060E provides 100 kHz. The wider bandwidth of the ACPL-C79B-000E enables faster transient response, making it better suited for applications with rapidly changing current waveforms.
Do both the ACPL-C79B-000E and ACPL-C780-060E operate from a single 5 V supply?
Yes, both devices operate from a single 5 V supply on the input side and a 3 V to 5.5 V supply on the output side, providing flexibility for interfacing with low-voltage ADCs and microcontrollers. This dual-supply architecture maintains galvanic isolation between the high-voltage and low-voltage domains.
What are the operating temperature ranges for the ACPL-C79B-000E and ACPL-C780-060E?
Both the ACPL-C79B-000E and ACPL-C780-060E are specified for an industrial operating temperature range of -40°C to +105°C, ensuring reliable performance in harsh industrial environments including motor control, inverter, and renewable energy systems.
Which part is more suitable for cost-sensitive designs?
The ACPL-C780-060E is generally the more cost-effective option, offering ±1% gain accuracy and 100 kHz bandwidth at a lower price point than the ACPL-C79B-000E. For applications where ±1% accuracy and 100 kHz bandwidth are sufficient, the ACPL-C780-060E provides an economical isolated amplification solution.
