Replacement verdict
Compatible functional replacement candidate
ADM3202ARN and ADM3202ARN-REEL7 are the same ADM3202ARN device offered in different packaging formats, so they are functionally interchangeable as drop-in replacements. The only meaningful distinction is the shipping form, which does not affect electrical performance, footprint, or board-level behavior.

Frequently asked questions
What is the difference between ADM3202ARN and ADM3202ARN-REEL7?
Both parts are the same ADM3202 device in a 16-lead narrow-body SOIC package (RN suffix). The difference is packaging format: ADM3202ARN is supplied in standard tube packaging, while ADM3202ARN-REEL7 is supplied on a 7-inch tape-and-reel for automated pick-and-place assembly. Electrical and functional specifications are identical.
Are ADM3202ARN and ADM3202ARN-REEL7 electrically and functionally identical?
Yes. Both are the same ADM3202 die and package; the -REEL7 suffix only denotes tape-and-reel shipping. Datasheet parameters such as data rate, supply voltage range, and driver/receiver characteristics apply equally to both ordering codes.
What is the function of the ADM3202?
The ADM3202 is a dual-channel RS-232 line driver/receiver that operates from a single 3.3 V supply, using internal charge-pump voltage converters to generate the RS-232-compatible output levels. It provides two drivers and two receivers in a 16-lead SOIC package.
What supply voltage does the ADM3202 require?
The ADM3202 operates from a single 3.3 V nominal supply (3.0 V to 5.5 V range per the datasheet). It should not be confused with 5 V-only RS-232 transceivers.
What data rate does the ADM3202 support?
The ADM3202 supports data rates up to 460 kbps, as specified in the manufacturer datasheet.
Can ADM3202ARN and ADM3202ARN-REEL7 be used interchangeably in a design?
Yes, from an electrical and footprint standpoint they are interchangeable because they are the same device and package. The choice depends only on the assembly process: tube for manual or low-volume assembly, and 7-inch tape-and-reel for automated SMT lines.
What package do ADM3202ARN and ADM3202ARN-REEL7 use?
Both use the 16-lead narrow-body SOIC (RN) package. PCB land patterns and pinouts are identical for both ordering codes.
Does the -REEL7 suffix affect moisture sensitivity or handling requirements?
No. The -REEL7 suffix specifies tape-and-reel packing only. Moisture sensitivity level and handling requirements are determined by the package and are the same for both ordering codes; refer to the manufacturer datasheet for the specified MSL.
