Replacement verdict
Compatible functional replacement candidate
The ACPL-C784-500E and ACPL-C78A-060E are both isolated analog amplifiers from Broadcom's ACPL-C78x series, sharing the same core architecture, isolation performance, and gain characteristics. The ACPL-C784-500E is supplied in a surface-mount SO-8 package with tape-and-reel packaging, while the ACPL-C78A-060E is supplied in a through-hole DIP-8 package. The primary distinction lies in the package mounting style and the specified gain tolerance grade, which may affect direct board-level interchangeability without layout adaptation. Designers should verify mechanical compatibility and gain accuracy requirements before substituting one for the other.

Frequently asked questions
What are the ACPL-C784-500E and ACPL-C78A-060E?
Both are Broadcom ACPL-C78x series optically isolated sigma-delta modulator amplifiers designed for isolated current and voltage sensing in motor control, power conversion, and industrial applications. The ACPL-C784-500E is supplied in a 16-lead SOIC wide-body package and is delivered in tape-and-reel packaging (suffix 500E), while the ACPL-C78A-060E is supplied in a 16-lead SOIC wide-body package with a tube packaging option (suffix 060E).
What is the difference between the ACPL-C784-500E and ACPL-C78A-060E?
The primary differences are the ordering suffix and packaging format. The ACPL-C784-500E uses the 500E tape-and-reel option, while the ACPL-C78A-060E uses the 060E tube option. Both share the same ACPL-C78x functional core, isolated sigma-delta modulator architecture, and 16-lead SOIC wide-body package footprint. Electrical specifications should be verified against the respective Broadcom datasheet for the exact ordering part number.
Are the ACPL-C784-500E and ACPL-C78A-060E pin-compatible?
Yes. Both devices are offered in the same 16-lead SOIC wide-body package with the same pinout, so they are pin-compatible at the package level. However, designers should confirm the exact pin functions and any datasheet-specific notes for each ordering part number before substituting one for the other in an existing design.
What is the isolation voltage rating of these devices?
Broadcom ACPL-C78x series isolated sigma-delta modulators are specified with a 5 kVrms isolation rating for the wide-body SOIC package, with UL, CSA, and IEC/EN/DIN EN 60747-5-5 recognition. The exact isolation parameters, working voltage, and transient immunity should be confirmed from the official Broadcom datasheet for the specific ordering part number.
What is the input signal range and supply voltage for the ACPL-C784-500E and ACPL-C78A-060E?
These ACPL-C78x devices are designed for a nominal ±200 mV input signal range with a 5 V supply on the isolated side and a 3.3 V or 5 V supply on the non-isolated side, depending on the specific configuration. The exact recommended operating conditions, input range, and supply voltage limits must be verified from the Broadcom datasheet for the exact ordering part number.
Can the ACPL-C784-500E and ACPL-C78A-060E be used interchangeably in a design?
Because both parts share the same ACPL-C78x functional core and 16-lead SOIC wide-body package, they are electrically and mechanically interchangeable in most designs. The only difference is the packaging option (tape-and-reel versus tube). Designers should still validate the exact ordering part number against the target design requirements and the manufacturer datasheet before substitution.
What certifications and safety approvals apply to these components?
Broadcom ACPL-C78x series isolated modulators carry UL 1577 recognition, CSA component acceptance, and IEC/EN/DIN EN 60747-5-5 approval for reinforced insulation. The specific certification file numbers and approval conditions should be confirmed from the official Broadcom datasheet and the respective certification bodies for the exact ordering part number.
What are the typical applications for the ACPL-C784-500E and ACPL-C78A-060E?
Typical applications include isolated current sensing in motor drives and inverters, isolated voltage sensing in power supplies and solar inverters, industrial process control, and other systems requiring galvanic isolation between high-voltage and low-voltage domains. Both ordering part numbers are suitable for these applications because they share the same ACPL-C78x functional core.
