Replacement verdict
Compatible functional replacement candidate
The ADM3055EBRIZ-RL is a functionally compatible replacement candidate for the ADM3050EBRIZ, sharing the same isolated CAN transceiver architecture, SOIC-16 package footprint, and 5 kV rms isolation rating. Designers should validate the higher maximum data rate and the reinforced isolation grade against their specific application requirements before final qualification.

Key electrical and mechanical differences between the two devices
| Parameter | ADM3050EBRIZ | ADM3055EBRIZ-RL | Why it matters |
|---|---|---|---|
| Data Rate | 12 Mbps | 12 Mbps | Determines the maximum bus speed the transceiver can support; identical rates mean equivalent throughput capability. |
| Isolation Rating | 5 kV rms | 5 kV rms | Defines the galvanic isolation level for safety and noise immunity; matching ratings allow direct substitution in isolated designs. |
| Supply Voltage | 5 V (VCC) / 5 V (VIO) | 5 V (VCC) / 5 V (VIO) | Must match the system power rails; identical supply requirements ensure pin-compatible power design. |
| Duplex Mode | Half-duplex | Half-duplex | Determines bus topology and protocol compatibility; both being half-duplex means they are interchangeable in the same network configuration. |
| Number of Channels | 1 TX / 1 RX | 1 TX / 1 RX | Channel count defines the transceiver's data path; matching counts confirm functional equivalence. |
| Package / Mounting | 16-SOIC (SOIC-16), Surface Mount | 16-SOIC (SOIC-16), Surface Mount | Package and footprint must match for PCB layout compatibility; identical packages allow drop-in replacement. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Ensures reliable operation across environmental conditions; matching ranges confirm suitability for the same applications. |
| Protocol Standard | CAN / CAN FD (ISO 11898) | CAN / CAN FD (ISO 11898) | Defines the communication protocol supported; identical standards guarantee interoperability on the same bus. |
| Integrated Isolated DC-DC | No | Yes | An integrated isolated power supply eliminates an external DC-DC converter, affecting board space, BOM cost, and design complexity. |

Frequently asked questions
What are the key differences between the ADM3050EBRIZ and ADM3055EBRIZ-RL?
Both are isolated CAN transceivers from Analog Devices in a 16-lead SOIC package. The ADM3050EBRIZ is a 5 kV rms isolated CAN transceiver with basic isolation, while the ADM3055EBRIZ-RL is a 5 kV rms isolated CAN transceiver with reinforced isolation and is supplied in tape-and-reel packaging (RL suffix). The ADM3055E family provides reinforced isolation per IEC 60747-17, whereas the ADM3050E provides basic isolation.
Are the ADM3050EBRIZ and ADM3055EBRIZ-RL pin-compatible?
Yes. Both devices are offered in the same 16-lead SOIC_W package with the same pinout, so they are pin-compatible. However, because the isolation rating differs (basic vs. reinforced), the ADM3055EBRIZ-RL should be selected where reinforced isolation is required by the application's safety standard.
What data rate do these isolated CAN transceivers support?
Both the ADM3050EBRIZ and ADM3055EBRIZ-RL support CAN FD data rates up to 12 Mbps, making them suitable for high-speed CAN and CAN FD networks in industrial and automotive-adjacent applications.
What is the difference in isolation rating between the two parts?
The ADM3050EBRIZ provides 5 kV rms basic isolation, while the ADM3055EBRIZ-RL provides 5 kV rms reinforced isolation. Reinforced isolation offers a higher level of protection and is typically required for safety-critical applications governed by standards such as IEC 61800-5-1 or IEC 60601-1.
What supply voltages do the ADM3050EBRIZ and ADM3055EBRIZ-RL require?
Both devices operate with a single 5 V supply on the logic side (VCC) and an isolated 5 V supply on the bus side (VISO), consistent with the ADM3050E/ADM3055E family specifications. The integrated isolated DC-to-DC converter in the ADM3055E generates the isolated bus-side supply from the primary side.
Does the ADM3055EBRIZ-RL include an integrated isolated power supply?
Yes. The ADM3055E family integrates an isolated DC-to-DC converter that supplies the isolated bus side, eliminating the need for a separate isolated power module. The ADM3050E family also integrates an isolated DC-to-DC converter, so both parts provide isolated power, but the ADM3055E is specified for reinforced isolation.
What does the "-RL" suffix indicate on the ADM3055EBRIZ-RL?
The "-RL" suffix indicates tape-and-reel packaging, which is intended for automated high-volume PCB assembly. The ADM3050EBRIZ is supplied in standard tube or tray packaging. The electrical and isolation specifications are determined by the base part number, not the packaging suffix.
Can the ADM3050EBRIZ be replaced by the ADM3055EBRIZ-RL in an existing design?
Because both parts are pin-compatible and share the same 16-lead SOIC footprint, the ADM3055EBRIZ-RL can generally be used where the ADM3050EBRIZ was designed in, provided the design's isolation requirements are met or exceeded by the reinforced rating. The designer must verify that the higher isolation specification and any associated creepage/clearance requirements are acceptable for the target application and that the tape-and-reel packaging suits the assembly process.
