Replacement verdict
Compatible functional replacement candidate
The ADM3055EBRIZ-RL is a viable functional replacement candidate for the ADM3050EBRWZ-RL, sharing the same isolated CAN transceiver function, 5 Mbps data rate, and 5 kV rms isolation rating, while offering an extended supply voltage range and higher temperature capability. Designers should validate the SOIC-20 wide-body footprint change and confirm supply rail compatibility before substituting in existing layouts.

Key electrical and mechanical differences between the two devices
| Parameter | ADM3050EBRWZ-RL | ADM3055EBRIZ-RL | Why it matters |
|---|---|---|---|
| Isolation Rating | 5 kV rms | 5 kV rms | Both provide reinforced isolation, so safety and creepage/clearance requirements are met equally. |
| Data Rate | 12 Mbps | 12 Mbps | Identical maximum CAN FD data rate ensures the same bus throughput capability. |
| Package / Mounting | 16-Lead SOIC_W (wide body), surface mount | 20-Lead SOIC_W (wide body), surface mount | Different pin count and footprint means the PCB layout must be redesigned; they are not drop-in replacements. |
| Supply Voltage (VCC) | 5 V (single supply) | 5 V (single supply) | Same supply rail simplifies power design and compatibility with existing 5 V systems. |
| Integrated DC-DC Converter | No (requires external isolated supply) | Yes (isoPower integrated isolated DC-DC) | The ADM3055E includes an integrated isolated power supply, eliminating an external isolated DC-DC and reducing board space and BOM. |
| Number of Channels | 1 (transceiver only) | 1 transceiver + integrated power | The ADM3055E integrates power isolation, changing the system architecture and external component count. |
| Operating Temperature Range | -40°C to +125°C | -40°C to +125°C | Identical industrial temperature range supports the same harsh-environment applications. |
| CAN FD Support | Yes | Yes | Both support CAN FD, so protocol-level compatibility is maintained. |
| Typical Supply Current | Lower (no integrated DC-DC) | Higher (includes isoPower DC-DC) | The integrated DC-DC in the ADM3055E increases current consumption, affecting thermal and power budgeting. |

Frequently asked questions
What are the key differences between the ADM3050EBRWZ-RL and the ADM3055EBRIZ-RL?
The ADM3050EBRWZ-RL is a basic isolated CAN transceiver in a 16-lead SOIC_W package, while the ADM3055EBRIZ-RL is an isolated CAN FD transceiver with an integrated isolated DC-to-DC converter in a 20-lead SOIC_W package. The ADM3055E supports CAN FD data rates up to 12 Mbps and provides an integrated isoPower isolated power supply, whereas the ADM3050E is a signal-only isolator requiring an external isolated supply.
Are the ADM3050EBRWZ-RL and ADM3055EBRIZ-RL pin-to-pin compatible?
No. The ADM3050EBRWZ-RL uses a 16-lead SOIC_W package, and the ADM3055EBRIZ-RL uses a 20-lead SOIC_W package. The different lead counts and pinouts mean they are not drop-in replacements for each other and require different PCB land patterns.
Does the ADM3055EBRIZ-RL include an integrated isolated power supply?
Yes. The ADM3055EBRIZ-RL integrates an isoPower isolated DC-to-DC converter, which supplies isolated power to the bus side and eliminates the need for a separate isolated power module. The ADM3050EBRWZ-RL does not include integrated isolated power and requires an external isolated supply for the bus side.
What data rates do these two isolated CAN transceivers support?
The ADM3050EBRWZ-RL supports CAN data rates up to 1 Mbps, consistent with classical CAN. The ADM3055EBRIZ-RL supports CAN FD data rates up to 12 Mbps, making it suitable for higher-bandwidth CAN FD networks.
What isolation voltage rating do the ADM3050EBRWZ-RL and ADM3055EBRIZ-RL provide?
Both devices are rated for 5 kV rms isolation, in accordance with the Analog Devices ADM3050E and ADM3055E datasheets. This rating applies to the reinforced isolation barrier between the logic side and the bus side.
Can the ADM3055EBRIZ-RL be used to replace the ADM3050EBRWZ-RL in an existing design?
Not directly. Because the ADM3055EBRIZ-RL has a different package (20-lead SOIC_W versus 16-lead SOIC_W), a different pinout, and includes an integrated isolated power supply, replacing the ADM3050EBRWZ-RL requires a PCB redesign and validation against the target design requirements. The two parts are not interchangeable without layout changes.
Which applications are better suited to the ADM3055EBRIZ-RL versus the ADM3050EBRWZ-RL?
The ADM3055EBRIZ-RL is better suited to space-constrained CAN FD designs that benefit from an integrated isolated power supply and higher data rates up to 12 Mbps. The ADM3050EBRWZ-RL is suited to classical CAN applications up to 1 Mbps where an external isolated supply is already available and a smaller 16-lead package is preferred.
