Replacement verdict
Compatible functional replacement candidate
The ADM3202ARN and ADM3202ARW-REEL are functionally equivalent RS-232 transceivers sharing the same core device, differing only in package form factor and shipping format. The ADM3202ARW-REEL is a valid functional substitute for the ADM3202ARN where board layout accommodates the wider SOIC-16W package, with validation recommended for footprint and thermal considerations.

Key electrical and mechanical differences between the two devices
| Parameter | ADM3202ARN | ADM3202ARW-REEL | Why it matters |
|---|---|---|---|
| Package / Case | 16-Lead SOIC (Narrow, 3.9 mm body) | 16-Lead SOIC_W (Wide, 7.5 mm body) | Footprint and board layout differ between narrow and wide SOIC, so the parts are not drop-in replacements on the same PCB pad pattern. |
| Packaging / Delivery Form | Tube / bulk | Tape & Reel | Tape and reel is required for automated pick-and-place assembly lines, while tubes suit manual or low-volume handling. |
| Number of Drivers / Receivers | 2 / 2 | 2 / 2 | Defines the RS-232 channel count; identical here, so both provide the same two-transmitter/two-receiver interface capability. |
| Data Rate | 460 kbps | 460 kbps | Maximum signaling speed must meet the application's baud requirement; matching values confirm equivalent throughput. |
| Supply Voltage | 3.0 V to 5.5 V | 3.0 V to 5.5 V | Operating voltage range determines compatibility with 3.3 V and 5 V logic systems; identical ranges mean the same supply design works for both. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Confirms both parts are rated for the same industrial temperature environment, so thermal suitability is equivalent. |
| Mounting Type | Surface Mount | Surface Mount | Assembly process compatibility; both are SMD, so the same reflow soldering process applies. |
| RoHS Compliance | RoHS compliant | RoHS compliant | Environmental/regulatory compliance for global markets; both meet the same RoHS requirement. |

Frequently asked questions
What are the key differences between the ADM3202ARN and ADM3202ARW-REEL?
Both devices are dual-channel RS-232 line drivers/receivers from Analog Devices based on the same ADM3202 core. The primary difference is the package and shipping format: the ADM3202ARN is supplied in a 16-lead narrow-body SOIC (R-16) tube/rail packaging, while the ADM3202ARW-REEL is supplied in a 16-lead wide-body SOIC (RW-16) in tape-and-reel format for automated assembly. Electrical specifications such as data rate, supply voltage range, and driver/receiver counts are equivalent between the two.
Are the ADM3202ARN and ADM3202ARW-REEL electrically interchangeable?
Functionally and electrically they share the same ADM3202 silicon design, including dual drivers, dual receivers, 3.0 V to 5.5 V supply operation, and charge-pump-based RS-232 levels. However, because the packages differ (narrow-body SOIC vs wide-body SOIC), the PCB land patterns are not identical, so a board designed for one package cannot accept the other without layout changes.
What supply voltage range do both devices support?
Both the ADM3202ARN and ADM3202ARW-REEL operate from a single 3.0 V to 5.5 V supply, using an on-chip charge pump to generate the RS-232-compliant positive and negative output voltages. This makes them suitable for mixed 3.3 V and 5 V systems.
What data rate can the ADM3202ARN and ADM3202ARW-REEL achieve?
Both variants are specified for data rates up to 460 kbps, which is the standard rating for the ADM3202 family. This supports typical RS-232 serial communication requirements in industrial and instrumentation applications.
How many drivers and receivers do these devices integrate?
Each device integrates two RS-232 drivers and two RS-232 receivers in a single 16-lead package, along with the charge pump circuitry required to generate RS-232 voltage levels from a single supply.
Why would a designer choose the ADM3202ARW-REEL over the ADM3202ARN?
The ADM3202ARW-REEL is supplied in tape-and-reel format, which is preferred for high-volume automated pick-and-place assembly lines. The wide-body SOIC (RW-16) package may also offer different thermal and mechanical characteristics. The ADM3202ARN in narrow-body SOIC tube packaging is typically chosen for prototyping, low-volume runs, or where board space favors the narrower footprint.
Do both parts share the same operating temperature range?
Both the ADM3202ARN and ADM3202ARW-REEL are specified over the industrial temperature range of −40 °C to +85 °C, consistent with the ADM3202 family datasheet. Designers should confirm the exact grade marking on the ordered part against the manufacturer datasheet for the specific lot.
Can the ADM3202ARN be replaced by the ADM3202ARW-REEL on an existing PCB?
Not as a drop-in replacement. Although the electrical function is the same, the narrow-body SOIC (R-16) and wide-body SOIC (RW-16) packages have different body widths and lead spans, so the PCB footprint must be redesigned. A direct substitution requires verifying package dimensions, land pattern, and assembly process against the Analog Devices datasheet for each package option.
