TLC0838ING4 Equivalent & Substitute Parts

Part Overview

The TLC0838ING4 is an 8-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for data acquisition applications requiring SAR (Successive Approximation Register) architecture. This device supports 4, 7, or 8 input channels with differential, pseudo-differential, and single-ended input configurations, communicating via SPI interface.

The TLC0838ING4 is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives for ongoing system support and new designs. The substitute part TLC0838IN maintains identical electrical and mechanical specifications while offering improved availability status.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC0838ING4 is based on strict equivalence across all critical electrical and mechanical parameters. The substitute part TLC0838IN is qualified as a direct equivalent because it maintains identical specifications in the following key areas:

• 8-bit resolution and 20k samples per second sampling rate
• Support for 4, 7, and 8 input channel configurations
• Identical input type support (Differential, Pseudo-Differential, Single Ended)
• SPI data interface and SAR architecture
• 5V analog and digital supply voltages
• -40°C to 85°C operating temperature range
• 20-DIP through-hole package with identical pinout and mechanical dimensions
• ROHS3 compliance and REACH unaffected status

Parameter Comparison

Engineering Selection Recommendations

The TLC0838IN is the qualified substitute for the TLC0838ING4 based on complete electrical and mechanical equivalence. Both devices are manufactured by Texas Instruments and maintain identical functional specifications across all critical parameters.

The TLC0838ING4 is discontinued at DiGi Electronics, while the TLC0838IN carries a Last Time Buy status, indicating limited future availability. For new designs and ongoing system support, the TLC0838IN should be selected as the primary component choice. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications.

Frequently Asked Questions (FAQ)

Q: Can the TLC0838IN be used as a direct replacement for the TLC0838ING4 in existing designs?

A: Yes. The TLC0838IN is electrically and mechanically equivalent to the TLC0838ING4. Both devices share identical pinout, package dimensions (20-DIP), supply voltages, and functional specifications. No circuit modifications are required for substitution.

Q: Are there differences in the package or mounting requirements?

A: No. Both the TLC0838ING4 and TLC0838IN use the same 20-DIP (0.300", 7.62mm) through-hole package with identical pin assignments and mechanical dimensions. PCB layouts and mounting procedures remain unchanged.

Q: What is the difference between the ING4 and IN package designations?

A: The package designations indicate different manufacturing or distribution batches from Texas Instruments. The electrical and functional specifications remain identical between these variants.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the TLC0838ING4 and TLC0838IN are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for industrial applications.

Q: What should be considered regarding product availability?

A: The TLC0838ING4 is discontinued at DiGi Electronics with no further stock expected. The TLC0838IN carries Last Time Buy status, indicating limited remaining inventory. For long-term supply requirements, procurement planning should account for the eventual discontinuation of both variants.
