ADS8341EB/2K5 Equivalent & Substitute Parts

Part Overview

The ADS8341EB/2K5 is a 16-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for data acquisition applications requiring high-resolution signal conversion. This SAR (Successive Approximation Register) architecture device supports 2 or 4 differential and single-ended inputs with a 100 kSPS sampling rate and SPI data interface. The part is currently in Active product status with 1302 units in stock. Finding equivalent and substitute parts is necessary when the primary part becomes unavailable, when alternative packaging options are required, or when supply chain optimization is needed while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ADS8341EB/2K5 are identified based on strict parametric equivalence across all critical electrical and mechanical specifications. The substitution logic is based on the following key parameters that must remain identical:

• 16-bit resolution
• 100 kSPS sampling rate
• 2 or 4 configurable input channels
• Differential and single-ended input support
• SPI serial data interface
• SAR architecture with external reference
• Dual supply voltage ranges (2.7V–3.6V and 5V for both analog and digital)
• Operating temperature range of -40°C to 85°C
• 16-SSOP surface mount package with 0.154" width (3.90mm)
• ROHS3 compliance and MSL 2 rating

The ADS8343E/2K5 meets all these criteria and qualifies as a parametric equivalent. Differences in product status and packaging format do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ADS8343E/2K5 is a direct parametric equivalent to the ADS8341EB/2K5 and is suitable for substitution in applications where all electrical and mechanical specifications must remain unchanged. Both parts are manufactured by Texas Instruments, maintain identical 16-bit SAR ADC architecture, and support the same supply voltage ranges, input configurations, and operating temperature specifications.

The primary distinction between these parts is product lifecycle status: the ADS8341EB/2K5 maintains Active status with current production, while the ADS8343E/2K5 is designated Last Time Buy, indicating limited future availability. The ADS8343E/2K5 is supplied in Tape & Reel packaging format, whereas the ADS8341EB/2K5 is available in bulk packaging. Both parts carry identical compliance certifications (ROHS3, MSL 2) and are suitable for equivalent circuit board integration.

Selection between these parts should be based on supply chain requirements, packaging format compatibility with assembly processes, and long-term availability planning.

Frequently Asked Questions (FAQ)

Q: Can the ADS8343E/2K5 be used as a direct replacement for the ADS8341EB/2K5 in existing designs?

A: Yes. The ADS8343E/2K5 is a parametric equivalent with identical electrical specifications, pin configuration, package dimensions, and functional performance. No circuit modifications are required for substitution.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging is suitable for manual assembly or small-volume production, while Tape & Reel packaging is optimized for automated pick-and-place assembly processes. Both formats contain the same component with identical specifications. Selection depends on manufacturing process requirements.

Q: Why is the ADS8343E/2K5 marked as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has announced the end of production for this part number. Existing inventory may be available, but future orders cannot be guaranteed. The ADS8341EB/2K5, with Active status, represents the current production alternative.

Q: Are there any differences in pin configuration or footprint between these parts?

A: No. Both parts use the 16-SSOP package with identical pin assignments, spacing, and footprint dimensions (0.154" width, 3.90mm). PCB designs and assembly fixtures are fully compatible.

Q: Do both parts support the same supply voltage ranges?

A: Yes. Both the ADS8341EB/2K5 and ADS8343E/2K5 support analog and digital supply voltages of 2.7V–3.6V or 5V, with identical operating specifications across these ranges.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, carry MSL 2 rating (1 Year), and are REACH Unaffected. They meet identical environmental and regulatory requirements for industrial and commercial applications.
