|---|---|---|---|
| Manufacturer Part Number | ACPL-C87A-500E | ACPL-C87B-000E | Distinct orderable part numbers indicate different gain/accuracy grades and packaging options, so they are not drop-in identical. |
| Gain Tolerance | ±1% | ±0.5% | Tighter gain tolerance improves measurement accuracy in isolated voltage sensing applications. |
| Gain Error Grade | A grade | B grade | The grade determines the specified accuracy class and directly affects system calibration requirements. |
| Packaging / Option Suffix | 500E tape and reel | 000E tube | Different packaging affects automated assembly compatibility and handling for production lines. |
| Isolation Voltage | 5000 Vrms | 5000 Vrms | Isolation rating is critical for safety and compliance in high-voltage measurement systems. |
| Input Type | Isolated analog voltage input | Isolated analog voltage input | Matching input type ensures the device interfaces with the same sensing front end. |
| Output Type | Differential analog output | Differential analog output | Identical output topology allows reuse of the same downstream ADC or signal conditioning circuit. |
| Supply Voltage | 5 V | 5 V | Same supply voltage means no power rail redesign is needed when substituting parts. |
| Operating Temperature Range | -40°C to +105°C | -40°C to +105°C | Equivalent temperature range ensures both parts can be used in the same industrial environments. |
| Package Type | SO-8 (stretched) | SO-8 (stretched) | Same package footprint allows direct PCB placement without layout changes. |

Frequently asked questions
What are the ACPL-C87A-500E and ACPL-C87B-000E?
The ACPL-C87A-500E and ACPL-C87B-000E are optically isolated voltage sensors from Broadcom (formerly Avago Technologies). They are designed for isolated voltage sensing in applications such as motor drives, inverters, and industrial control systems, providing galvanic isolation between the high-voltage and low-voltage sides.
What is the difference between the ACPL-C87A-500E and ACPL-C87B-000E?
The primary difference is the gain tolerance and packaging option. The ACPL-C87A-500E offers a tighter gain tolerance of ±1%, while the ACPL-C87B-000E has a gain tolerance of ±3%. Additionally, the ACPL-C87A-500E is supplied in tape and reel packaging (suffix 500E), whereas the ACPL-C87B-000E is supplied in tube packaging (suffix 000E).
Are the ACPL-C87A-500E and ACPL-C87B-000E pin-compatible?
Yes, both devices are pin-compatible. They share the same package type (SO-8 stretched) and pinout, allowing them to be used interchangeably on the same PCB footprint, provided the gain tolerance and packaging requirements are acceptable for the application.
What is the isolation voltage rating for these components?
Both the ACPL-C87A-500E and ACPL-C87B-000E have a rated isolation voltage of 5000 Vrms for 1 minute per UL 1577. They also offer a working voltage of 1414 Vpeak per IEC/EN/DIN EN 60747-5-5, making them suitable for high-voltage isolation applications.
What is the input voltage range of the ACPL-C87A-500E and ACPL-C87B-000E?
Both devices have an input voltage range of ±200 mV, with a nominal input voltage of 200 mV. They are designed to sense small differential voltages across a shunt resistor in isolated voltage sensing applications.
Can the ACPL-C87A-500E and ACPL-C87B-000E be used in safety-critical applications?
Yes, both devices are certified to relevant safety standards, including UL 1577, CSA, and IEC/EN/DIN EN 60747-5-5. However, the specific safety requirements of the end application must be evaluated to ensure compliance. The ACPL-C87A-500E with tighter gain tolerance may be preferred for applications requiring higher accuracy.
What is the operating temperature range for these components?
Both the ACPL-C87A-500E and ACPL-C87B-000E are specified for an operating temperature range of -40°C to +105°C, making them suitable for industrial and automotive environments.
Which part should be selected for a new design, ACPL-C87A-500E or ACPL-C87B-000E?
The selection depends on the required gain accuracy and production packaging. Choose the ACPL-C87A-500E for applications needing tighter gain tolerance (±1%) and tape-and-reel packaging for automated assembly. Choose the ACPL-C87B-000E for applications where a ±3% gain tolerance is acceptable and tube packaging is preferred. Both offer identical isolation and input voltage specifications.
