Replacement verdict
Compatible functional replacement candidate
The ADM202EARN-REEL is a functionally compatible candidate for the ADM202JRN, sharing the same dual RS-232 driver/receiver function, 16-pin narrow SOIC package, and 5 V supply. The primary distinction is the enhanced ESD protection rating on the ADM202EARN-REEL, which exceeds the standard rating of the ADM202JRN. Designers should confirm ESD robustness requirements and verify the exact operating temperature grade before substituting in production.

Key electrical and mechanical differences between the two devices
| Parameter | ADM202JRN | ADM202EARN-REEL | Why it matters |
|---|---|---|---|
| Number of Drivers/Receivers | 2/2 | 2/2 | Both are dual transceivers; matching driver/receiver counts ensures pin and functional compatibility. |
| Data Rate | 120 kbps | 120 kbps | Maximum data rate must meet the application's signaling speed for reliable communication. |
| Supply Voltage | 5 V | 5 V | Operating supply voltage must match the system rail to avoid level incompatibility. |
| Operating Temperature Range | 0°C to +70°C | -40°C to +85°C | The extended industrial temperature range of the EARN version allows use in harsher environments where the commercial-grade JRN part may not be rated. |
| ESD Protection (IEC 1000-4-2) | Not specified / standard | ±15 kV (air), ±8 kV (contact) | Enhanced ESD protection on the EARN version improves robustness in exposed interface applications. |
| Package / Mounting | 16-SOIC (surface mount) | 16-SOIC (surface mount) | Identical package and footprint allow direct board-level substitution without layout changes. |
| Number of Pins | 16 | 16 | Pin count and pinout must match for drop-in replacement. |
| RoHS Compliance | Not RoHS compliant (contains lead) | RoHS compliant | RoHS status affects regulatory compliance and solder process selection for the final assembly. |
| Packaging | Tube | Tape & Reel | Packaging format determines compatibility with automated pick-and-place assembly lines. |

Frequently asked questions
What are the key differences between the ADM202JRN and ADM202EARN-REEL?
Both are dual RS-232 line drivers/receivers from Analog Devices. The ADM202JRN is specified for the commercial temperature range (0°C to +70°C) and is supplied in a 16-lead SOIC (R-16) package in tube form. The ADM202EARN-REEL is specified for the industrial temperature range (−40°C to +85°C) and is supplied in a 16-lead SOIC (R-16) package in tape-and-reel form for automated assembly. The "E" suffix denotes the enhanced/industrial temperature grade, and "REEL" denotes tape-and-reel packaging.
Are the ADM202JRN and ADM202EARN-REEL pin-compatible?
Yes. Both devices are offered in the same 16-lead SOIC (R-16) package with the same pinout, so they are pin-compatible when the temperature grade and packaging differences are acceptable for the application.
Can the ADM202JRN be replaced by the ADM202EARN-REEL in an existing design?
Functionally the two parts share the same RS-232 driver/receiver architecture and pinout, so the ADM202EARN-REEL can generally serve as a drop-in replacement where the wider industrial temperature range is acceptable. The designer should confirm that the operating temperature range, packaging (tape-and-reel vs tube), and any datasheet-specified parameters meet the target design requirements before substitution.
What is the difference in operating temperature range between the two parts?
The ADM202JRN is rated for the commercial temperature range of 0°C to +70°C. The ADM202EARN-REEL is rated for the industrial temperature range of −40°C to +85°C, making it suitable for harsher environments.
What packaging options do the ADM202JRN and ADM202EARN-REEL use?
Both devices are supplied in a 16-lead SOIC (R-16) package. The ADM202JRN is typically shipped in tubes, while the ADM202EARN-REEL is supplied in tape-and-reel format intended for automated pick-and-place assembly lines.
Do both parts support the same RS-232 data rate and supply voltage?
Yes. Both the ADM202JRN and ADM202EARN-REEL are dual RS-232 drivers/receivers that operate from a single +5 V supply and support data rates up to 120 kbps, consistent with the ADM202 family datasheet specifications. Designers should still verify the exact datasheet revision for the specific grade before finalizing a design.
Which part should be selected for an industrial-temperature application?
The ADM202EARN-REEL should be selected for applications requiring operation over −40°C to +85°C, since the ADM202JRN is limited to the 0°C to +70°C commercial range. The tape-and-reel packaging of the ADM202EARN-REEL also suits high-volume automated assembly.
