TLC0831IDR Equivalent & Substitute Parts

Part Overview

The TLC0831IDR is an 8-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for single-channel data acquisition applications. This SAR (Successive Approximation Register) architecture device operates with external voltage references and communicates via SPI interface. The part is currently in active production status with 1209 units in stock. Equivalent and substitute parts are identified to support design flexibility, inventory management, and supply chain continuity for applications requiring 8-bit ADC functionality in 8-SOIC packaging.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLC0831IDR are qualified based on the following critical parameters that determine functional compatibility:

Core Compatibility Criteria:

• Resolution: 8-bit ADC architecture
• Input Configuration: Single input channel supporting differential and single-ended modes
• Communication Protocol: SPI data interface
• Converter Architecture: SAR (Successive Approximation Register)
• Reference Configuration: External voltage reference
• Package Type: 8-SOIC form factor with 0.154" width (3.90mm)
• Mounting: Surface mount technology
• Regulatory Compliance: ROHS3 compliant, REACH unaffected, EAR99 classification

Substitution Constraints: The TLC0831IDR operates at fixed 5V supply (both analog and digital). Substitute parts from the LTC1096 series (Analog Devices Inc.) provide equivalent 8-bit SAR ADC functionality with flexible supply voltage ranges (3V ~ 9V), enabling operation in the 5V environment while offering broader application flexibility. All substitute parts maintain identical package geometry, SPI interface, external reference architecture, and regulatory compliance status.

Engineering Selection Recommendations

TLC0831IDR (Primary Part) Select this part when Texas Instruments supply chain preference is established or when fixed 5V supply operation is the sole design requirement. The device maintains active production status with 1209 units in current inventory.

LTC1096AIS8#PBF This substitute provides equivalent 8-bit SAR ADC performance with extended supply voltage range (3V ~ 9V) and full industrial temperature range (-40°C ~ 85°C). Suitable for applications requiring design flexibility across multiple voltage domains. 905 units in stock.

LTC1096IS8#PBF This substitute offers identical specifications to LTC1096AIS8#PBF with full industrial temperature range (-40°C ~ 85°C). Recommended for applications requiring extended temperature operation. 885 units in stock.

LTC1096CS8#PBF This substitute operates within commercial temperature range (0°C ~ 70°C) with flexible supply voltage (3V ~ 9V). Select this part only when application temperature requirements are limited to commercial specifications. 2000 units in stock. Not suitable for industrial temperature applications.

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 classification, ensuring regulatory equivalence with the primary part.

Frequently Asked Questions (FAQ)

Q: Can LTC1096 series parts directly replace the TLC0831IDR without PCB modifications? A: Yes. All substitute parts share identical 8-SOIC package geometry (0.154" width, 3.90mm), pin count, and SPI interface pinout. Direct socket substitution is possible without PCB layout changes.

Q: What is the key difference between LTC1096AIS8#PBF and LTC1096IS8#PBF? A: Both parts are functionally identical with 8-bit resolution, 33k sampling rate, and -40°C ~ 85°C operating temperature. The primary difference is manufacturer device package designation (AIS vs IS suffix). Both support 3V ~ 9V supply voltage range.

Q: Why does LTC1096CS8#PBF have different temperature specifications? A: LTC1096CS8#PBF is rated for commercial temperature range (0°C ~ 70°C) versus industrial range (-40°C ~ 85°C) for other LTC1096 variants. Select this part only when application environment is guaranteed to remain within commercial temperature limits.

Q: Are the LTC1096 parts compatible with 5V-only designs? A: Yes. The LTC1096 series supports 3V ~ 9V supply voltage, which includes 5V operation. The TLC0831IDR operates at fixed 5V, while LTC1096 parts offer broader voltage flexibility for the same 5V application environment.

Q: What is the sampling rate difference between TLC0831IDR and LTC1096 substitutes? A: TLC0831IDR operates at 31k samples per second, while LTC1096 series parts operate at 33k samples per second. This 2k difference is within typical application tolerance for 8-bit ADC systems and does not affect functional compatibility.

Q: Do all parts require external voltage reference? A: Yes. Both TLC0831IDR and all LTC1096 substitute parts require external voltage reference configuration. Internal reference options are not available in these device families.

Q: Are packaging options different between the main part and substitutes? A: TLC0831IDR is supplied in Tape & Reel (TR) packaging, while LTC1096 substitutes are supplied in Tube packaging. Both packaging formats are suitable for surface mount assembly; tube packaging is standard for component distribution.
