Replacement verdict
Compatible functional replacement candidate
The ACPL-C784-500E and ACPL-C780-060E are both isolated analog amplifiers from Broadcom's ACPL-C78x series, sharing the same SO-8 package, isolation architecture, and functional topology. The ACPL-C784-500E offers a higher gain tolerance grade and is supplied in tape-and-reel packaging, while the ACPL-C780-060E is a standard gain-grade device in tube packaging. Because the two parts are functionally interchangeable in most isolated current-sensing and voltage-sensing applications, the ACPL-C784-500E can be considered a compatible functional replacement candidate for the ACPL-C780-060E, provided the designer validates gain accuracy, packaging format, and thermal derating for the target application.

Frequently asked questions
What are the ACPL-C784-500E and ACPL-C780-060E?
The ACPL-C784-500E and ACPL-C780-060E are Broadcom isolation amplifiers designed for current sensing and voltage sensing in motor control, power conversion, and industrial applications. Both are optically isolated amplifiers that provide galvanic isolation between the high-voltage and low-voltage sides of a system.
What is the key difference between the ACPL-C784-500E and ACPL-C780-060E?
The primary difference is the specified gain tolerance and package option. The ACPL-C784-500E offers a tighter gain tolerance of ±1% and is supplied in a 500-piece tape-and-reel package, while the ACPL-C780-060E has a gain tolerance of ±3% and is supplied in a 60-piece tube package. Both share the same functional architecture and isolation ratings.
Are the ACPL-C784-500E and ACPL-C780-060E pin-to-pin compatible?
Yes. Both devices are offered in the same 8-pin surface-mount (DIP-8/SO-8) package with identical pin assignments, allowing them to share the same PCB footprint. However, the ACPL-C784-500E is delivered in tape-and-reel and the ACPL-C780-060E in tubes, so the packaging format differs.
What is the isolation voltage rating of these isolation amplifiers?
Both the ACPL-C784-500E and ACPL-C780-060E are rated for 5,000 Vrms for 1 minute per UL 1577 and provide reinforced insulation with a working voltage of 1,140 Vpeak per IEC/EN/DIN EN 60747-5-5. These ratings are common to both variants.
What is the input offset voltage and gain error specification for each part?
The ACPL-C784-500E specifies a gain tolerance of ±1% and an input offset voltage of ±0.3 mV (typical). The ACPL-C780-060E specifies a gain tolerance of ±3% and an input offset voltage of ±0.5 mV (typical). These differences make the C784 variant preferable for applications requiring higher measurement accuracy.
Can the ACPL-C784-500E and ACPL-C780-060E be used interchangeably in a design?
They are functionally interchangeable in terms of pinout and isolation performance, but they are not identical in accuracy specifications. A design that requires the tighter ±1% gain tolerance of the ACPL-C784-500E should not substitute the ACPL-C780-060E without verifying that the ±3% tolerance is acceptable for the application. Always confirm against the manufacturer datasheet before substitution.
What is the operating temperature range for these isolation amplifiers?
Both the ACPL-C784-500E and ACPL-C780-060E are specified for an operating temperature range of –40°C to +105°C, making them suitable for industrial and automotive-grade environments.
What are the typical applications for the ACPL-C784-500E and ACPL-C780-060E?
Typical applications include motor phase current sensing, inverter current sensing, switched-mode power supply feedback, and general isolated voltage or current measurement in industrial, automotive, and renewable energy systems. The ACPL-C784-500E is preferred where higher gain accuracy is required, while the ACPL-C780-060E suits cost-sensitive designs with looser accuracy requirements.
