TLC0831CDG4 Equivalent & Substitute Parts

Part Overview

The TLC0831CDG4 is an 8-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for single-channel data acquisition applications. It features a Successive Approximation Register (SAR) architecture with SPI digital interface and operates from a 5V supply. The device is packaged in an 8-SOIC surface mount package.

The TLC0831CDG4 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC0831CDG4 is determined by strict equivalence across the following critical parameters:

• Resolution: 8-bit ADC architecture
• Sampling Rate: 31k samples per second
• Input Configuration: Single input channel supporting both differential and single-ended modes
• Digital Interface: SPI protocol
• Supply Voltage: 5V analog and digital supplies
• Package: 8-SOIC surface mount form factor
• Temperature Range: 0°C to 70°C operating specification

The TLC0831CD meets all these criteria and is therefore a direct functional equivalent. Both parts share identical electrical specifications, pin configuration, and package dimensions, enabling pin-for-pin replacement.

Parameter Comparison

Engineering Selection Recommendations

The TLC0831CD is the primary substitute for the discontinued TLC0831CDG4. Both devices are manufactured by Texas Instruments and maintain identical electrical and mechanical specifications across all critical parameters.

The TLC0831CD carries Active product status with confirmed inventory availability (2197 pieces in stock), ensuring reliable sourcing for new designs and production requirements. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications.

The packaging difference (TLC0831CD supplied in Tube format versus the original CDG4) does not affect functional compatibility or PCB assembly procedures for surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can the TLC0831CD replace the TLC0831CDG4 in existing designs?

A: Yes. The TLC0831CD is a direct pin-for-pin equivalent with identical electrical specifications, pin configuration, and package dimensions. No circuit modifications are required.

Q: Are there differences in performance between these parts?

A: No. Both devices share identical resolution (8-bit), sampling rate (31k SPS), input configuration (1 channel, differential/single-ended), supply voltage (5V), and operating temperature range (0°C to 70°C).

Q: What is the difference between the packaging designations?

A: The TLC0831CDG4 and TLC0831CD both use 8-SOIC surface mount packages with identical physical dimensions (0.154" width, 3.90mm). The primary difference is the supplier packaging format (Tube for TLC0831CD). This does not affect PCB assembly or electrical performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the TLC0831CDG4 and TLC0831CD are ROHS3 compliant and REACH unaffected, meeting environmental and regulatory standards for industrial applications.

Q: Why is the TLC0831CDG4 discontinued?

A: The TLC0831CDG4 is discontinued at DiGi Electronics. The TLC0831CD remains in active production and is the recommended substitute for continued component sourcing.
