Replacement verdict
Compatible functional replacement candidate
The ADM3050EBRIZ and ADM3050EBRWZ are functionally equivalent isolated CAN transceivers from the same ADM3050E family, differing only in package and temperature grade. The SOIC-16 wide-body variant is a viable replacement candidate for the 16-lead SOIC narrow-body variant where board footprint and the extended temperature range are acceptable, with no change to signal integrity, isolation performance, or CAN protocol behavior.

Key electrical and mechanical differences between the two devices
| Parameter | ADM3050EBRIZ | ADM3050EBRWZ | Why it matters |
|---|---|---|---|
| Package / Case | 16-Lead SOIC (R-16) | 16-Lead SOIC (RW-16, wide body) | The package footprint and body width differ, so the two parts are not drop-in board replacements for each other even though the die is functionally similar. |
| Isolation Voltage (VISO) | 5 kV rms | 5 kV rms | Both meet the same reinforced isolation rating, so safety-related creepage/clearance requirements are equivalent at the rating level (though package dimensions still govern layout). |
| Data Rate | 12 Mbps | 12 Mbps | Identical CAN FD data rate capability means both support the same bus speed and timing budget in the application. |
| Supply Voltage (VCC) | 5 V (4.5 V to 5.5 V) | 5 V (4.5 V to 5.5 V) | Same supply range ensures both can be powered from the same 5 V rail without regulator changes. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Identical industrial temperature range means both are suitable for the same harsh-environment applications. |
| Number of Channels / Direction | 1 Tx / 1 Rx (CAN transceiver) | 1 Tx / 1 Rx (CAN transceiver) | Same channel configuration confirms both are single-channel isolated CAN transceivers with equivalent signal flow. |
| Creepage / Clearance | ~5.0 mm (SOIC-R) | ~8.0 mm (SOIC-RW wide body) | The wide-body RW package provides greater creepage/clearance, which can be critical for higher working-voltage or reinforced isolation compliance in the final layout. |
| Mounting Type | Surface Mount | Surface Mount | Both are SMD devices, so assembly process compatibility is the same; only the land pattern differs due to body width. |

Frequently asked questions
What is the primary difference between the ADM3050EBRIZ and the ADM3050EBRWZ?
The primary difference is the package type and corresponding temperature range. The ADM3050EBRIZ is supplied in a 16-lead SOIC_W package and is specified for the industrial temperature range of −40°C to +125°C. The ADM3050EBRWZ is supplied in a 16-lead SOIC_W package with a different pinout/creepage configuration and is specified for the industrial temperature range of −40°C to +105°C. Both are isolated CAN transceivers with integrated isolated DC-to-DC converters, but the package and thermal ratings differ.
Are the ADM3050EBRIZ and ADM3050EBRWZ functionally interchangeable?
No, they are not drop-in interchangeable. Although both are 5 kV rms signal and power isolated CAN transceivers with integrated isolated DC-to-DC converters, the ADM3050EBRIZ and ADM3050EBRWZ use different package variants (SOIC_W with different creepage/clearance and pin configurations). PCB land patterns, isolation spacing, and thermal performance must be validated against the respective datasheets before substitution.
What data rate do the ADM3050EBRIZ and ADM3050EBRWZ support?
Both devices support CAN FD data rates up to 12 Mbps, making them suitable for high-speed CAN and CAN FD networks. This is a shared specification across the ADM3050E family and is verified in the Analog Devices datasheet.
What isolation rating do these devices provide?
Both the ADM3050EBRIZ and ADM3050EBRWZ provide 5 kV rms isolation for both the signal and power channels, compliant with UL 1577 and CSA standards. The isolation barrier is integrated, eliminating the need for a separate isolated DC-to-DC converter.
What is the operating temperature range for each variant?
The ADM3050EBRIZ is rated for −40°C to +125°C. The ADM3050EBRWZ is rated for −40°C to +105°C. Designers should select the variant whose temperature rating meets the application's thermal environment.
Do both parts include an integrated isolated DC-to-DC converter?
Yes. Both the ADM3050EBRIZ and ADM3050EBRWZ integrate an isolated DC-to-DC converter that supplies power to the isolated side of the transceiver, simplifying design and reducing board space compared to discrete isolation solutions.
Which package options are available for the ADM3050EBRIZ and ADM3050EBRWZ?
The ADM3050EBRIZ is offered in a 16-lead SOIC_W package. The ADM3050EBRWZ is also offered in a 16-lead SOIC_W package but with a different pinout and creepage configuration optimized for specific isolation spacing requirements. Refer to the Analog Devices datasheet for exact package drawings and land patterns.
Are these devices compliant with CAN FD and ISO 11898-2 standards?
Yes. Both the ADM3050EBRIZ and ADM3050EBRWZ are compliant with ISO 11898-2 (CAN physical layer) and support CAN FD operation up to 12 Mbps, as specified in the Analog Devices datasheet.
