Replacement verdict
Compatible functional replacement candidate
The ADM211EARSZ and ADM213AR-REEL are both RS-232 transceivers from Analog Devices with matching driver/receiver counts, supply voltage ranges, and SOIC-28 footprints, making them strong functional replacement candidates. However, the ADM213AR-REEL offers an extended operating temperature range and a higher data rate, while the ADM211EARSZ includes an internal charge pump and shutdown capability. Designers should validate the specific interface requirements and thermal conditions before substituting one for the other.

Key electrical and mechanical differences between the two devices
| Parameter | ADM211EARSZ | ADM213AR-REEL | Why it matters |
|---|---|---|---|
| Number of Drivers | 4 | 4 | Driver count determines how many RS-232 transmit lines the device can support; both match here. |
| Number of Receivers | 5 | 5 | Receiver count determines how many RS-232 receive lines are available; both match here. |
| Data Rate | 120 kbps | 120 kbps | Maximum data rate must meet the serial link speed requirement; both support the same rate. |
| Supply Voltage | 5 V | 5 V | Operating supply voltage must match the system rail; both are 5 V single-supply devices. |
| ESD Protection (IEC 1000-4-2) | ±15 kV | ±15 kV | ESD rating affects robustness in harsh environments; both offer the same enhanced ESD protection. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Temperature range must cover the application environment; both are industrial-grade. |
| Package / Mounting | 20-Lead SSOP (surface mount) | 28-Lead SOIC (surface mount) | Package footprint and pin count differ, so PCB layout and land pattern are not drop-in compatible. |
| Number of Pins | 20 | 28 | Pin count affects board layout and available signal pins; the two parts are not pin-compatible. |
| Charge Pump / Capacitor Configuration | External capacitors required | External capacitors required | Both require external charge-pump capacitors, affecting BOM and board area. |
| Shutdown / Enable Feature | Yes (active-low shutdown) | Yes (active-low shutdown) | Shutdown capability enables low-power standby; both provide it, supporting similar power-management behavior. |

Frequently asked questions
What are the primary differences between the ADM211EARSZ and ADM213AR-REEL?
The ADM211EARSZ is a 5 V, dual-channel RS-232 line driver/receiver in a 28-lead SSOP package (RS-232 transceiver with ±15 kV ESD protection on all I/O pins, 0.1 µF charge pump capacitors, and a 120 kbps data rate). The ADM213AR-REEL is a 5 V, dual-channel RS-232 transceiver in a 28-lead SOIC package (0.1 µF charge pump capacitors, 120 kbps data rate, and ±15 kV ESD protection on RS-232 I/O pins). The key differences are package type (SSOP vs SOIC) and the reel packaging option for the ADM213AR-REEL.
Are the ADM211EARSZ and ADM213AR-REEL pin-compatible?
No. The ADM211EARSZ uses a 28-lead SSOP (Shrink Small Outline Package) body, while the ADM213AR-REEL uses a 28-lead SOIC (Small Outline Integrated Circuit) body. These are different package footprints with different lead pitches and PCB land patterns, so they are not drop-in pin-compatible replacements without a board redesign.
Do both devices support the same RS-232 data rate?
Yes. Both the ADM211EARSZ and ADM213AR-REEL are specified for a maximum data rate of 120 kbps, which is the standard rating for these Analog Devices RS-232 transceiver families using 0.1 µF charge pump capacitors.
What ESD protection do the ADM211EARSZ and ADM213AR-REEL provide?
Both devices feature ±15 kV ESD protection on their RS-232 I/O pins, compliant with the IEC 1000-4-2 (EN 61000-4-2) standard for air-gap and contact discharges, as specified in the Analog Devices datasheets for these parts.
What is the difference in packaging between the two part numbers?
The ADM211EARSZ is supplied in a 28-lead SSOP tube or tray format (the "Z" suffix indicates lead-free/RoHS-compliant packaging). The ADM213AR-REEL is supplied on a 28-lead SOIC tape-and-reel (the "-REEL" suffix denotes reel packaging), which is intended for automated pick-and-place assembly lines.
Can the ADM211EARSZ be used as a direct substitute for the ADM213AR-REEL in an existing design?
Not without PCB modification. Although both are 5 V dual-channel RS-232 transceivers with similar electrical specifications (120 kbps, 0.1 µF charge pump capacitors, ±15 kV ESD), the SSOP vs SOIC package difference means the land patterns, lead pitch, and board space requirements differ. A layout change is required before substitution.
Are both parts RoHS compliant and lead-free?
The ADM211EARSZ carries the "Z" suffix, which in Analog Devices nomenclature denotes lead-free, RoHS-compliant packaging. The ADM213AR-REEL is also available in RoHS-compliant lead-free versions per the manufacturer's ordering guide; designers should confirm the specific ordering code and compliance status against the current Analog Devices datasheet and product page before finalizing.
