Replacement verdict
Compatible functional replacement candidate
The ADM3202ARN and ADM3202ARW are functionally equivalent RS-232 transceivers sharing identical electrical characteristics, driver/receiver counts, and supply voltage requirements; the only material distinction is the package outline (narrow-body SOIC vs. wide-body SOIC), which affects PCB footprint but not circuit behavior. Designers can treat them as interchangeable for signal-chain purposes provided the board layout accommodates the respective package width.

Key electrical and mechanical differences between the two devices
| Parameter | ADM3202ARN | ADM3202ARW | Why it matters |
|---|---|---|---|
| Package / Case | 16-Lead SOIC (Narrow, 3.90 mm body) | 16-Lead SOIC (Wide, 7.50 mm body) | The package footprint and body width differ, so the two parts are not drop-in replacements on the same PCB land pattern. |
| Mounting Type | Surface Mount | Surface Mount | Both are surface-mount devices, but the differing package width still affects board layout compatibility. |
| Supplier Device Package | 16-SOIC | 16-SOIC (Wide) | Assembly and reflow profiles must match the specific package outline; the wide-body variant requires different pad geometry. |
| Number of Drivers/Receivers | 2/2 | 2/2 | Identical transceiver channel count ensures the same interface capability for RS-232 communication. |
| Data Rate | 460 kbps | 460 kbps | Matching maximum data rate confirms equivalent throughput for the serial link. |
| Operating Supply Voltage | 3.0 V to 5.5 V | 3.0 V to 5.5 V | Same supply range means both parts work in identical 3.3 V or 5 V system rails. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Identical temperature ratings ensure the same environmental robustness in the target application. |
| Protocol | RS-232 | RS-232 | Both implement the same RS-232 protocol, preserving interface compatibility. |
| Duplex | Full | Full | Full-duplex operation on both parts supports simultaneous transmit and receive. |

Frequently asked questions
What is the primary difference between the ADM3202ARN and ADM3202ARW?
The primary difference is the package type: the ADM3202ARN is supplied in a 16-lead narrow-body SOIC (N-16-1) package, while the ADM3202ARW is supplied in a 16-lead wide-body SOIC (RW-16) package. Both are dual-channel RS-232 line drivers/receivers from Analog Devices with the same electrical core.
Are the ADM3202ARN and ADM3202ARW electrically identical?
Yes. Both variants share the same datasheet specifications: 3.0 V to 5.5 V single-supply operation, two drivers and two receivers, data rates up to 460 kbps, and compliance with EIA-232-E and V.28/V.24 standards. The silicon die and electrical performance are the same; only the package body width differs.
Can the ADM3202ARN and ADM3202ARW be used interchangeably on the same PCB?
No, not without a layout change. The narrow-body SOIC (ARN) and wide-body SOIC (ARW) have different package widths and lead spans, so the PCB land patterns are not compatible. A board designed for one package will not accept the other without redesigning the footprint.
What are the operating temperature ranges for these devices?
Both the ADM3202ARN and ADM3202ARW are specified over the industrial temperature range of −40°C to +85°C, as stated in the Analog Devices datasheet.
Do the ADM3202ARN and ADM3202ARW require external charge-pump capacitors?
Yes. Both devices use on-chip charge-pump circuitry to generate RS-232 voltage levels from a single 3.0 V to 5.5 V supply, and they require external capacitors. The datasheet specifies four 0.1 µF capacitors (or larger, depending on the supply voltage) for the charge pump.
What data rate do the ADM3202ARN and ADM3202ARW support?
Both variants support data rates up to 460 kbps, per the Analog Devices datasheet, while maintaining EIA-232-E and V.28/V.24 compliance.
Which package should be selected for a new design, the ADM3202ARN or ADM3202ARW?
Selection depends on board space and layout constraints. The narrow-body SOIC (ARN) occupies less board width and is preferred where space is tight, while the wide-body SOIC (ARW) offers a larger lead span that may suit existing layouts or specific assembly requirements. Both are electrically equivalent, so the choice is purely mechanical.
