Replacement verdict
Compatible functional replacement candidate
The ADM213EARSZ is a functionally compatible replacement candidate for the ADM213AR, sharing the same core RS-232 transceiver architecture, channel configuration, and supply voltage range. Designers should validate the ESD rating improvement and confirm the SOIC-28 package footprint and operating temperature range against the target application before final qualification.

Key electrical and mechanical differences between the two devices
| Parameter | ADM213EARSZ | ADM213AR | Why it matters |
|---|---|---|---|
| Mounting / Package | Surface Mount, 28-SSOP | Surface Mount, 28-SOIC (Wide) | Different package footprints mean the parts are not drop-in board replacements; PCB layout must match the specific package. |
| ESD Protection (RS-232 I/O) | ±15 kV (IEC 1000-4-2 Air/Ground) | ±2 kV (standard ESD) | The "E" variant offers enhanced ESD robustness, which affects reliability in harsh or exposed interface environments. |
| Number of Drivers / Receivers | 4 / 5 | 4 / 5 | Matching driver/receiver counts confirm equivalent channel capacity for the RS-232 interface. |
| Data Rate | 120 kbps | 120 kbps | Identical maximum data rate ensures the same throughput capability in the application. |
| Supply Voltage | 5 V (single supply) | 5 V (single supply) | Same supply requirement allows use in the same power rail design without modification. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Equivalent temperature range ensures comparable environmental operating limits. |
| On-Chip Charge Pump | Yes (internal) | Yes (internal) | Both integrate the charge pump, so no external ± voltage supplies are needed in either case. |
| Shutdown / Enable Feature | Yes | Yes | Both support low-power shutdown, preserving the same power-management behavior. |

Frequently asked questions
What are the key differences between the ADM213EARSZ and the ADM213AR?
The ADM213EARSZ is a lead-free (Pb-free), RoHS-compliant variant in a 28-lead SSOP package, while the ADM213AR is the older leaded (SnPb) version in the same 28-lead SSOP package. Functionally both are +5 V, dual-channel RS-232 line drivers/receivers with the same pinout, but the ADM213EARSZ is specified over the industrial temperature range and carries the "E" enhanced ESD designation, whereas the ADM213AR is the standard commercial-grade part.
Are the ADM213EARSZ and ADM213AR pin-compatible?
Yes. Both devices are offered in the same 28-lead SSOP (RS-28) package with identical pin assignments, so they are pin-compatible when the PCB land pattern supports the SSOP body. Designers should still confirm the exact package drawing in the respective datasheets before substituting.
What supply voltage and interface standard do these parts support?
Both the ADM213EARSZ and ADM213AR operate from a single +5 V supply and implement RS-232 line driver/receiver functions with on-chip charge pump converters that generate the required positive and negative RS-232 voltage levels from the +5 V rail.
How many drivers and receivers do the ADM213EARSZ and ADM213AR provide?
Each device integrates four RS-232 drivers and five RS-232 receivers, matching the ADM213 family configuration. This makes them suitable for multi-channel serial interfaces such as those found in computers, peripherals, and instrumentation.
Does the ADM213EARSZ offer better ESD protection than the ADM213AR?
The ADM213EARSZ carries the "E" suffix denoting enhanced ESD protection on the RS-232 I/O pins, per the Analog Devices ADM213E datasheet. The ADM213AR is the standard ESD-rated version. Designers requiring higher ESD robustness should verify the exact ESD specification in the respective datasheet before selecting between the two.
What is the significance of the "Z" suffix in ADM213EARSZ?
The "Z" suffix in Analog Devices nomenclature indicates a lead-free (Pb-free), RoHS-compliant package finish. The ADM213AR, lacking the "Z," uses a leaded (SnPb) finish. This matters for RoHS compliance and for solder reflow profile selection in manufacturing.
Can the ADM213EARSZ be used as a drop-in replacement for the ADM213AR in existing designs?
Because both parts share the same 28-lead SSOP footprint, pinout, +5 V supply, and 4-driver/5-receiver architecture, the ADM213EARSZ can generally serve as a drop-in replacement for the ADM213AR. However, the designer must confirm the operating temperature range, ESD rating, and RoHS requirements of the target application against the ADM213EARSZ datasheet before qualifying the substitution.
What operating temperature range do these devices support?
The ADM213EARSZ is specified over the industrial temperature range of −40 °C to +85 °C, consistent with the "E" enhanced grade. The ADM213AR is specified over the commercial temperature range of 0 °C to +70 °C. Applications exposed to sub-zero or elevated ambient temperatures should use the ADM213EARSZ.
