Replacement verdict
Compatible functional replacement candidate
The AM26C31ID and AM26C31IDR are functionally equivalent quad differential line drivers from the same manufacturer, sharing identical electrical specifications, logic function, and package type. The only distinction is the packaging format—tube versus tape and reel—making the AM26C31IDR a direct functional substitute for the AM26C31ID in automated assembly environments.

Key electrical and mechanical differences between the two devices
| Parameter | AM26C31ID | AM26C31IDR | Why it matters |
|---|---|---|---|
| Function | Quadruple differential line driver | Quadruple differential line driver | Both parts perform the same core function, so they are functionally interchangeable in a circuit. |
| Number of Drivers | 4 | 4 | The driver count determines how many differential lines each device can drive. |
| Supply Voltage Range | 4.5 V to 5.5 V | 4.5 V to 5.5 V | The supply range must match the system rail to ensure proper operation and logic-level compatibility. |
| Output Type | Differential (3-state) | Differential (3-state) | Three-state differential outputs allow bus sharing and support balanced transmission standards. |
| Data Rate | Up to 10 Mbps | Up to 10 Mbps | The maximum data rate determines whether the device suits the target communication speed. |
| Operating Temperature Range | -40 °C to 85 °C | -40 °C to 85 °C | The temperature range must cover the application environment for reliable operation. |
| Package / Mounting | 16-SOIC, surface mount | 16-SOIC, surface mount | Package and mounting style must match the PCB footprint for physical compatibility. |
| Packaging / Reel Size | Tube | Tape & Reel (2000 units) | Packaging differs for automated assembly versus manual handling, though the device itself is identical. |

Frequently asked questions
What is the difference between the AM26C31ID and the AM26C31IDR?
The AM26C31ID and AM26C31IDR are the same device: a quad differential line driver in the AM26C31 family. The suffix difference is packaging format. The AM26C31ID is supplied in tube/rail packaging, while the AM26C31IDR is supplied in tape-and-reel packaging for automated assembly. Both use the same SOIC-16 (D) package and have identical electrical specifications.
Are the AM26C31ID and AM26C31IDR electrically and functionally identical?
Yes. Both are quad differential line drivers with three-state outputs, designed for balanced transmission lines. They share the same datasheet parameters, including supply voltage range, output drive characteristics, propagation delays, and pinout. The only documented difference is the shipping/packaging format.
Can the AM26C31IDR be used as a drop-in replacement for the AM26C31ID?
Yes, from a form, fit, and function perspective. Both are the same die in the same SOIC-16 (D) package with the same pinout. The AM26C31IDR is simply the tape-and-reel variant, so it can replace the AM26C31ID in designs that use the SOIC-16 package, provided the assembly process supports reel-fed components.
What package do the AM26C31ID and AM26C31IDR use?
Both devices are offered in the SOIC-16 (D) package, a 16-pin small-outline integrated circuit package. The package body and pin configuration are identical between the two orderable part numbers.
Why would a designer choose the AM26C31IDR over the AM26C31ID?
The AM26C31IDR is supplied in tape-and-reel, which is preferred for high-volume automated pick-and-place assembly lines. The AM26C31ID in tube/rail packaging is typically used for prototyping, low-volume runs, or manual assembly. The choice is a manufacturing/logistics decision, not an electrical one.
Do the AM26C31ID and AM26C31IDR have the same operating temperature range and supply requirements?
Yes. Both are specified with the same recommended operating conditions and temperature range as documented in the shared AM26C31 datasheet. Because they are the same device in the same package, supply voltage range, logic input levels, and output characteristics are identical.
Are the AM26C31ID and AM26C31IDR RoHS compliant?
Both orderable part numbers are lead-free (RoHS-compliant) versions of the AM26C31 in the SOIC-16 package, consistent with the manufacturer's Pb-free designation for the "ID" and "IDR" suffixes. Designers should confirm the current compliance status on the manufacturer's or authorized distributor's product page for the specific orderable part number.
