Replacement verdict
Not a drop-in replacement
The ADM3072EARZ and ADM3050EBRWZ are not drop-in replacements for one another. Although both are Analog Devices isolated RS-485 transceivers, they differ in isolation technology, data rate, package footprint, and channel configuration, so a direct board-level substitution is not possible without design changes and revalidation.

Key electrical and mechanical differences between the two devices
| Parameter | ADM3072EARZ | ADM3050EBRWZ | Why it matters |
|---|---|---|---|
| Protocol / Standard | RS-485 / RS-422 | CAN FD (ISO 11898) | These devices support fundamentally different serial bus protocols, so they are not functionally interchangeable in the same network. |
| Data Rate | 250 kbps (slew-rate limited) | 12 Mbps | Maximum bus speed determines whether the part meets the timing requirements of the target application. |
| Number of Transceivers / Channels | 1 driver, 1 receiver (half-duplex) | 1 transceiver (CAN FD) | Channel configuration affects how the device connects to the bus and whether it fits the system topology. |
| Duplex Mode | Half-duplex | Half-duplex (differential CAN bus) | Duplex mode determines wiring requirements and whether simultaneous transmit/receive is possible. |
| Supply Voltage | 3.0 V to 3.6 V (single 3.3 V supply) | 4.5 V to 5.5 V (VCC) with integrated isolated DC-DC | Supply voltage compatibility is essential for direct board-level substitution and power rail design. |
| Galvanic Isolation | No | Yes (5 kV rms signal and power isolation) | Isolation protects against ground loops and high common-mode voltages; its presence or absence changes safety and layout requirements. |
| Package | 8-lead SOIC (R-8) | 16-lead SOIC (RW-16) | Package footprint and pin count must match the PCB layout for a drop-in replacement. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +105 °C | Temperature range determines suitability for industrial or harsh-environment applications. |
| Fail-Safe Receiver | Yes (open/short fail-safe) | Yes (bus fault protection up to ±40 V) | Fail-safe behavior ensures a defined logic state on the bus under fault conditions, affecting system robustness. |

Frequently asked questions
What are the primary functional differences between the ADM3072EARZ and the ADM3050EBRWZ?
The ADM3072EARZ is a 3.3 V, ±15 kV ESD protected, half-duplex RS-485/RS-422 transceiver specified for data rates up to 250 kbps. The ADM3050EBRWZ is a 5 kV rms isolated, CAN FD transceiver compliant with ISO 11898-2:2016, supporting data rates up to 12 Mbps. They serve different bus protocols (RS-485 vs. CAN FD) and are not functionally interchangeable.
Are the ADM3072EARZ and ADM3050EBRWZ pin-to-pin compatible?
No. The ADM3072EARZ is offered in an 8-lead SOIC package with a standard RS-485 transceiver pinout (RO, RE, DE, DI, GND, A, B, VCC). The ADM3050EBRWZ is offered in a 16-lead SOIC wide-body package with a different pinout that includes isolated CAN pins (VCC1, GND1, TXD, RXD, VIO, GND2, VCC2, CANH, CANL, and no-connect pins). The packages and pin functions differ, so they are not drop-in replacements.
Do both devices provide galvanic isolation?
Only the ADM3050EBRWZ provides galvanic isolation, rated at 5 kV rms per UL 1577 and CSA. The ADM3072EARZ is a non-isolated RS-485/RS-422 transceiver and does not include an isolation barrier.
What are the supported data rates for each device?
The ADM3072EARZ supports data rates up to 250 kbps, as specified in the Analog Devices datasheet. The ADM3050EBRWZ supports CAN FD data rates up to 12 Mbps, per the Analog Devices datasheet and ISO 11898-2:2016 compliance.
What supply voltages do the ADM3072EARZ and ADM3050EBRWZ require?
The ADM3072EARZ operates from a single 3.3 V supply (VCC). The ADM3050EBRWZ uses a dual-supply arrangement: VCC1 on the logic side and VCC2 on the isolated bus side, with a separate VIO pin for logic-level interfacing; refer to the datasheet for the specified supply voltage ranges.
What ESD protection levels are specified for each part?
The ADM3072EARZ is specified with ±15 kV ESD protection on the RS-485 bus pins (A and B), per the Analog Devices datasheet. The ADM3050EBRWZ datasheet specifies ESD protection on the CAN bus pins (CANH and CANL); consult the datasheet for the exact IEC 61000-4-2 contact and air-discharge ratings.
Can the ADM3072EARZ be used in a CAN network, or the ADM3050EBRWZ in an RS-485 network?
No. The ADM3072EARZ is an RS-485/RS-422 transceiver and does not implement CAN protocol signaling or differential CAN bus characteristics. The ADM3050EBRWZ is a CAN FD transceiver designed for ISO 11898-2 CAN bus physical layers and is not specified for RS-485 operation. Each device must be used with its intended bus protocol.
What are the operating temperature ranges for these devices?
Both the ADM3072EARZ and the ADM3050EBRWZ are specified for the industrial temperature range of −40 °C to +85 °C, per their respective Analog Devices datasheets.
