Replacement verdict
Compatible functional replacement candidate
The ADM3050EBRWZ and ADM3056EBRIZ-RL are both isolated CAN transceivers from the same ADI family and share core signal-chain characteristics, but they differ in isolation rating, package, and regulatory certification scope. The ADM3056EBRIZ-RL is a viable functional substitute for the ADM3050EBRWZ only after confirming the isolation voltage margin, creepage/clearance, and certification requirements of the target design.

Key electrical and mechanical differences between the two devices
| Parameter | ADM3050EBRWZ | ADM3056EBRIZ-RL | Why it matters |
|---|---|---|---|
| Data Rate | 12 Mbps | 12 Mbps | Maximum bus speed supported; both meet the same CAN FD fast data rate, so timing compatibility is equivalent. |
| Isolation Rating | 5 kV rms | 5 kV rms | Galvanic isolation level protects the bus side from high voltages; identical ratings mean equivalent safety margin. |
| Supply Voltage (VCC) | 5 V (single supply) | 5 V (single supply) | Determines power rail requirements; both use a single 5 V supply, simplifying drop-in replacement. |
| Package / Mounting | 16-Lead SOIC_W (wide body), surface mount | 16-Lead SOIC_W (wide body), surface mount | Footprint and assembly compatibility; matching package allows PCB reuse without layout changes. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Industrial temperature range ensures reliable operation in harsh environments; identical ranges mean equal thermal capability. |
| Number of Channels | 1 Tx / 1 Rx (transceiver) | 1 Tx / 1 Rx (transceiver) | Channel configuration defines bus interface capability; both provide a single bidirectional CAN channel. |
| Integrated Isolated DC-DC | Yes (isoPower) | Yes (isoPower) | On-chip isolated power eliminates external supplies; both integrate it, so system complexity is equivalent. |
| Common-Mode Transient Immunity | 100 kV/µs (typical) | 100 kV/µs (typical) | High CMTI ensures data integrity in noisy industrial environments; matching values indicate equivalent noise immunity. |

Frequently asked questions
What are the key differences between the ADM3050EBRWZ and the ADM3056EBRIZ-RL?
The ADM3050EBRWZ is a 5 kV rms isolated CAN transceiver in a 16-lead SOIC_W package, while the ADM3056EBRIZ-RL is a 5 kV rms isolated CAN FD transceiver in a 20-lead SOIC_W package with an integrated isolated DC-to-DC converter. The ADM3056E supports CAN FD data rates up to 12 Mbps and provides an isolated power output, whereas the ADM3050E is a signal-only isolator requiring an external isolated supply.
Are the ADM3050EBRWZ and ADM3056EBRIZ-RL pin-to-pin compatible?
No. The ADM3050EBRWZ uses a 16-lead SOIC_W package, and the ADM3056EBRIZ-RL uses a 20-lead SOIC_W package. The different pin counts and pin functions prevent direct pin-to-pin substitution; the PCB land pattern must be redesigned.
Do both devices support CAN FD?
No. The ADM3056EBRIZ-RL is specified for CAN FD operation with data rates up to 12 Mbps. The ADM3050EBRWZ is a classic CAN transceiver rated for data rates up to 1 Mbps and is not specified for CAN FD.
Does the ADM3056EBRIZ-RL include isolated power, and does the ADM3050EBRWZ?
The ADM3056EBRIZ-RL integrates an isolated DC-to-DC converter that supplies isolated power to the bus side, eliminating the need for a separate isolated supply. The ADM3050EBRWZ does not include an isolated power converter and requires an external isolated supply for the bus-side circuitry.
What is the isolation rating of each device?
Both the ADM3050EBRWZ and the ADM3056EBRIZ-RL are rated for 5 kV rms isolation, suitable for reinforced isolation requirements in industrial CAN networks.
What are the supply voltage requirements for each part?
The ADM3050EBRWZ operates from a single 5 V supply on the logic side and requires an external isolated supply for the bus side. The ADM3056EBRIZ-RL operates from a 5 V supply and generates its own isolated bus-side power through the integrated DC-to-DC converter, so no external isolated supply is needed.
Which device is better suited for space-constrained designs?
The ADM3050EBRWZ occupies a smaller 16-lead SOIC_W footprint and is preferable when board space is limited and an external isolated supply is already available. The ADM3056EBRIZ-RL uses a larger 20-lead SOIC_W package but eliminates the external isolated supply, which can reduce total system footprint and component count.
Can the ADM3050EBRWZ be used as a drop-in replacement for the ADM3056EBRIZ-RL?
No. The devices differ in package, pinout, CAN FD support, and isolated power integration. A direct drop-in replacement is not possible; the design must be revalidated for package footprint, power architecture, and data-rate requirements.
