Replacement verdict
Compatible functional replacement candidate
The ADM3050EBRIZ is a viable functional replacement candidate for the ADM3054BRWZ-RL7 in isolated CAN applications, offering a higher-speed CAN FD transceiver in a smaller SOIC-16 package with comparable isolation ratings. Designers should validate the increased data rate capability, confirm the reduced package footprint against their PCB layout, and verify the isolation and supply voltage requirements against the target application before final qualification.

Key electrical and mechanical differences between the two devices
| Parameter | ADM3054BRWZ-RL7 | ADM3050EBRIZ | Why it matters |
|---|---|---|---|
| Data Rate | 1 Mbps | 12 Mbps | Maximum bus speed supported; the ADM3050EBRIZ supports much higher throughput, which may be required for faster CAN networks. |
| Isolation Rating | 5 kV rms | 5.7 kV rms | Galvanic isolation voltage between the bus and logic sides; higher ratings provide greater safety margin in harsh industrial environments. |
| Supply Voltage (VCC) | 5 V (single supply) | 5 V (VCC1) / 5 V (VCC2) | Operating supply configuration affects board-level power design and whether a single or dual supply rail is needed. |
| Package / Mounting | 16-Lead SOIC (wide body), surface mount | 20-Lead SOIC (wide body), surface mount | Footprint and pin count differ, so the two parts are not drop-in PCB compatible and require layout changes. |
| Number of Pins | 16 | 20 | Pin count determines package footprint and pinout compatibility for direct substitution. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +105°C | Wider temperature range of the ADM3050EBRIZ suits more demanding industrial environments. |
| Integrated DC-DC Converter | No (requires external isolated supply) | Yes (isoPower integrated isolated DC-DC) | An integrated isolated power supply simplifies design and reduces external components, a key functional difference. |
| Common-Mode Transient Immunity | 25 kV/µs | 100 kV/µs | Higher transient immunity improves reliability in electrically noisy industrial bus environments. |
| Protocol Support | CAN (ISO 11898) | CAN FD (ISO 11898-2) | CAN FD support enables higher data payloads and faster rates, affecting system-level compatibility. |

Frequently asked questions
What are the key differences between the ADM3054BRWZ-RL7 and the ADM3050EBRIZ?
The ADM3054BRWZ-RL7 is a 5 kV rms isolated CAN transceiver in a 16-lead SOIC_W package that integrates a digital isolator and a CAN transceiver, supporting data rates up to 1 Mbps. The ADM3050EBRIZ is a 5 kV rms signal and power isolated CAN FD transceiver in a 20-lead SOIC_W package with an integrated isolated DC-to-DC converter, supporting data rates up to 12 Mbps for CAN FD operation. The ADM3050EBRIZ provides higher data rate capability and integrated isolated power, while the ADM3054BRWZ-RL7 requires an external isolated supply.
Are the ADM3054BRWZ-RL7 and ADM3050EBRIZ pin-to-pin compatible?
No. The ADM3054BRWZ-RL7 is supplied in a 16-lead SOIC_W package, while the ADM3050EBRIZ is supplied in a 20-lead SOIC_W package. The different lead counts and pin assignments mean they are not drop-in replacements and require different PCB land patterns.
Do both devices support CAN FD?
The ADM3050EBRIZ supports CAN FD with data rates up to 12 Mbps. The ADM3054BRWZ-RL7 is specified for CAN data rates up to 1 Mbps and is not rated for CAN FD data rates. Designs requiring CAN FD should use the ADM3050EBRIZ.
What isolation rating do both parts provide?
Both the ADM3054BRWZ-RL7 and the ADM3050EBRIZ are rated for 5 kV rms isolation, verified per UL 1577. Designers should confirm the specific isolation parameters (such as working voltage and transient immunity) in the respective Analog Devices datasheets for their application.
Does the ADM3050EBRIZ include isolated power, and does the ADM3054BRWZ-RL7?
The ADM3050EBRIZ integrates an isolated DC-to-DC converter to supply power across the isolation barrier, eliminating the need for a separate isolated supply on the bus side. The ADM3054BRWZ-RL7 does not include an integrated isolated power converter and requires an external isolated supply for the bus-side circuitry.
What are the operating temperature ranges for these two transceivers?
Both the ADM3054BRWZ-RL7 and the ADM3050EBRIZ are specified for the industrial temperature range of −40 °C to +125 °C. Designers should verify the exact temperature grade in the Analog Devices datasheet for the specific orderable part number.
Which part should be selected for a new CAN FD design requiring isolated power?
The ADM3050EBRIZ is the appropriate choice because it supports CAN FD data rates up to 12 Mbps and integrates an isolated DC-to-DC converter, reducing external component count. The ADM3054BRWZ-RL7 is limited to 1 Mbps CAN and requires an external isolated supply, making it less suitable for CAN FD designs with space constraints.
