Replacement verdict
Compatible functional replacement candidate
The ADS8341E and ADS8341E/2K5G4 are functionally equivalent, sharing identical device specifications; the only distinction is packaging format, with the /2K5G4 variant supplied as tape-and-reel for automated assembly. Either part number can serve as a direct functional substitute for the other, provided the board assembly process accommodates the corresponding packaging.

Key electrical and mechanical differences between the two devices
| Parameter | ADS8341E | ADS8341E/2K5G4 | Why it matters |
|---|---|---|---|
| Resolution | 16 bit | 16 bit | Determines the smallest analog signal change the ADC can resolve; identical resolution means equivalent measurement precision. |
| Number of Input Channels | 4 single-ended / 2 differential | 4 single-ended / 2 differential | Defines how many analog signals can be measured; matching channel count ensures the same system-level input capability. |
| Sampling Rate | 200 kSPS | 200 kSPS | Sets the maximum conversion throughput; identical rates mean the same signal bandwidth can be captured. |
| Supply Voltage | 2.7 V to 5.25 V | 2.7 V to 5.25 V | Determines compatibility with the system power rail; matching ranges allow drop-in replacement without supply redesign. |
| Interface Type | SPI (serial) | SPI (serial) | Defines the digital communication protocol; identical interfaces ensure the same host controller connection works. |
| Package / Case | SSOP-16 | SSOP-16 | Determines PCB footprint and assembly compatibility; matching packages allow the same board layout. |
| Packaging / Ordering Format | Tube | Tape & Reel (2500 units) | Affects manufacturing handling and inventory; the /2K5G4 variant is reeled for automated high-volume assembly while the base part is typically tubed. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Defines the environmental operating envelope; matching ranges ensure equivalent reliability in the target application. |

Frequently asked questions
What is the difference between ADS8341E and ADS8341E/2K5G4?
Both parts are the same ADS8341 16-bit, 4-channel serial-output ADC die in the same SSOP-16 package. The difference is ordering format: ADS8341E is the standard tube/tray orderable part number, while ADS8341E/2K5G4 is the same device supplied on a 2,500-piece tape-and-reel with a G4 (green/RoHS-compliant) designation.
Are ADS8341E and ADS8341E/2K5G4 electrically and functionally identical?
Yes. Both share the same datasheet specifications for the ADS8341: 16-bit resolution, 4 single-ended or 2 differential input channels, SPI-compatible serial interface, and 2.7 V to 5 V single-supply operation. The /2K5G4 suffix denotes packaging and RoHS status, not a change in electrical performance.
Can ADS8341E/2K5G4 be used as a drop-in replacement for ADS8341E?
Yes, from a form, fit, and function standpoint, since both are the same device in the same SSOP-16 package. The only practical difference is delivery format (tape-and-reel vs. tube/tray), so board-level assembly is unaffected; verify your specific orderable part number and RoHS requirement against the manufacturer datasheet.
What does the /2K5G4 suffix mean on ADS8341E/2K5G4?
The "2K5" indicates a 2,500-piece reel quantity, and "G4" is the Texas Instruments green/RoHS-compliant designation. It does not indicate a different silicon revision or performance grade.
What are the key specifications shared by both ADS8341E and ADS8341E/2K5G4?
Both are 16-bit successive-approximation ADCs with 4 single-ended or 2 differential inputs, a serial (SPI/QSPI/Microwire-compatible) interface, single-supply operation from 2.7 V to 5 V, and an SSOP-16 package, per the ADS8341 datasheet.
Which package do ADS8341E and ADS8341E/2K5G4 use?
Both are supplied in the SSOP-16 (DB) package, so PCB footprint and pinout are identical between the two orderable part numbers.
Does the tape-and-reel format of ADS8341E/2K5G4 affect its handling or soldering?
No. Tape-and-reel is a packaging/delivery format for automated pick-and-place assembly. The device moisture sensitivity level, reflow profile, and solderability are governed by the same datasheet and package qualification as the tube/tray version.
Which part number should be ordered for high-volume automated assembly?
ADS8341E/2K5G4 is the appropriate choice for high-volume automated placement because it is supplied on a 2,500-piece tape-and-reel. ADS8341E in tube/tray is typically used for prototyping or low-volume runs.
