Replacement verdict
Compatible functional replacement candidate
The ADM3050EBRIZ is a viable functional replacement candidate for the ADM3053BRWZ in isolated CAN applications, sharing the same isolated CAN transceiver function and SOIC-16 wide-body footprint, though the designer must validate supply architecture, data rate, and isolation grade against the target design.

Key electrical and mechanical differences between the two devices
| Parameter | ADM3053BRWZ | ADM3050EBRIZ | Why it matters |
|---|---|---|---|
| Isolation Rating | 2.5 kV rms | 5 kV rms | Higher isolation voltage provides greater safety margin and robustness in industrial environments with large ground potential differences. |
| Data Rate | 1 Mbps | 12 Mbps | The maximum CAN bus data rate determines compatibility with high-speed CAN networks and overall system throughput. |
| Integrated DC-DC Converter | Yes (isoPower) | No | An integrated isolated power supply simplifies design and reduces board space; its absence requires an external isolated DC-DC converter. |
| Supply Voltage (VCC) | 5 V | 5 V (VCC1) / 5 V (VCC2, external) | Supply requirements affect power rail design and whether an external isolated supply must be provided for the bus side. |
| Package | 20-Lead SOIC_W | 16-Lead SOIC_W | Package footprint and pin count affect PCB layout and whether a drop-in replacement is possible. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +105°C | A wider temperature range enables use in harsher environments and provides greater thermal margin. |
| Number of Channels | 1 Tx / 1 Rx (CAN transceiver) | 1 Tx / 1 Rx (CAN transceiver) | Channel configuration confirms both are single-channel isolated CAN transceivers suitable for standard CAN bus nodes. |
| Propagation Delay | ~150 ns (typical) | ~75 ns (typical) | Lower propagation delay supports higher data rates and tighter timing budgets in the CAN network. |
| Common-Mode Transient Immunity | 25 kV/µs | 100 kV/µs | Higher transient immunity improves reliability in electrically noisy industrial environments. |

Frequently asked questions
What are the key differences between the ADM3053BRWZ and the ADM3050EBRIZ?
The ADM3053BRWZ is a fully isolated CAN transceiver with an integrated isolated DC-to-DC converter (isoPower) in a 20-lead SOIC_W package, supporting 5 Mbps data rates and 2.5 kV rms isolation. The ADM3050EBRIZ is a signal-isolated CAN FD transceiver without an integrated isolated power supply, in a 16-lead SOIC_W package, supporting up to 12 Mbps and 5 kV rms isolation. The ADM3050EBRIZ requires an external isolated supply on VISO, whereas the ADM3053BRWZ generates its own isolated power.
Are the ADM3053BRWZ and ADM3050EBRIZ pin-to-pin or footprint compatible?
No. The ADM3053BRWZ uses a 20-lead SOIC_W package, while the ADM3050EBRIZ uses a 16-lead SOIC_W package. They have different pin counts and pin functions, so they are not drop-in replacements and require different PCB land patterns.
Do both devices support CAN FD?
The ADM3050EBRIZ is specified for CAN FD operation with data rates up to 12 Mbps. The ADM3053BRWZ is specified for data rates up to 5 Mbps and is not characterized by Analog Devices as a CAN FD transceiver, so it should not be assumed to support CAN FD timing requirements.
What are the isolation voltage ratings of each device?
The ADM3053BRWZ is rated for 2.5 kV rms isolation. The ADM3050EBRIZ is rated for 5 kV rms isolation. The higher rating of the ADM3050EBRIZ makes it suitable for applications requiring reinforced isolation levels.
Does the ADM3050EBRIZ include an integrated isolated power supply like the ADM3053BRWZ?
No. The ADM3053BRWZ integrates an isolated DC-to-DC converter (isoPower) that supplies the isolated side, eliminating the need for a separate isolated supply. The ADM3050EBRIZ does not include isolated power and requires an external isolated supply on its VISO pin.
What are the supply voltage requirements for each part?
The ADM3053BRWZ operates from a single 5 V supply on VCC and generates the isolated side voltage internally. The ADM3050EBRIZ requires a 5 V supply on VCC and a separate isolated supply of 4.5 V to 5.5 V on VISO for the isolated side.
Which device is better suited for space-constrained designs?
The ADM3050EBRIZ is in a 16-lead SOIC_W package and requires an external isolated supply, while the ADM3053BRWZ is in a 20-lead SOIC_W package but integrates the isolated power converter. The ADM3050EBRIZ offers a smaller transceiver footprint, but the overall solution size depends on the external isolated supply components required.
Are both devices qualified for automotive or industrial temperature ranges?
Both the ADM3053BRWZ and ADM3050EBRIZ are specified for the industrial temperature range of −40°C to +85°C. Neither part should be assumed to be AEC-Q100 automotive qualified unless a specific automotive-grade variant is confirmed in the manufacturer datasheet.
