ADM3050EBRIZ vs ADM3056EBRIZ-RL

Both are isolated CAN transceivers from Analog Devices in a 16-lead SOIC package, but they differ in their isolation rating and regulatory certifications. The ADM3050EBRIZ is a 5 kV rms isolated CAN FD transceiver, while the ADM3056EBRIZ-RL is a 2.5 kV rms isolated CAN FD transceiver. The ADM3050E series is certified to UL 1577, CSA, and VDE 0884-11 (reinforced), whereas the ADM3056E series carries a lower isolation voltage rating and correspondingly different certification levels. Designers must confirm the required isolation grade against the system safety standard before selecting between them.

Yes. Both devices are offered in the same 16-lead SOIC_W package with an identical pinout, so they are pin-compatible at the package level. However, pin compatibility does not guarantee functional interchangeability; the isolation voltage rating, certification level, and certain timing parameters differ, so a direct drop-in substitution must be validated against the target design's isolation and safety requirements.

Yes. Both the ADM3050EBRIZ and the ADM3056EBRIZ-RL are isolated CAN FD transceivers designed to support CAN FD data rates up to 5 Mbps, while remaining compatible with classic CAN (up to 1 Mbps). The isolated CAN FD capability allows higher payload throughput in automotive and industrial networks without changing the physical layer topology.

The ADM3050EBRIZ provides 5 kV rms isolation, while the ADM3056EBRIZ-RL provides 2.5 kV rms isolation. The higher isolation rating of the ADM3050EBRIZ makes it suitable for applications requiring reinforced isolation under standards such as VDE 0884-11, whereas the ADM3056EBRIZ-RL targets applications with lower isolation requirements. The correct choice depends on the working voltage and safety class specified for the end equipment.

Both devices operate from 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 and ADM3056E family specifications. The isolated side supply is typically generated by an external isolated DC-DC converter or an integrated isoPower solution, depending on the specific variant. Designers should verify the exact supply rail requirements in the respective datasheets before finalizing the power architecture.

The ADM3050EBRIZ is certified to UL 1577 (5 kV rms for 1 minute), CSA Component Acceptance Notice 5A, and VDE 0884-11 reinforced insulation. The ADM3056EBRIZ-RL carries UL 1577 and CSA certifications at its 2.5 kV rms isolation level, with VDE certification corresponding to its lower isolation grade. Because certification levels differ, the ADM3056EBRIZ-RL cannot be substituted where the ADM3050EBRIZ's reinforced VDE rating is mandated by the application's safety standard.

Not unconditionally. Although both parts share the same 16-lead SOIC package and pinout, the ADM3056EBRIZ-RL has a lower isolation voltage rating (2.5 kV rms versus 5 kV rms) and different regulatory certifications. A drop-in replacement is only acceptable if the target design's isolation working voltage, safety standard, and certification requirements are satisfied by the lower-rated device. Otherwise, the ADM3050EBRIZ must be retained.

The -RL suffix denotes tape-and-reel packaging for the ADM3056EBRIZ, which is the standard shipping format for high-volume automated assembly. The ADM3050EBRIZ is typically supplied in tube or tray packaging unless a reel variant is explicitly ordered. The electrical and isolation specifications are identical between the reel and non-reel versions of the same base part number; only the packaging quantity and format differ.
