ADS7841ES/2K5 Equivalent & Substitute Parts

Part Overview

The ADS7841ES/2K5 is a 12-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, configured as a 4-input SAR (Successive Approximation Register) architecture device in a 16-SSOP surface mount package. This component operates across dual supply voltage ranges (2.7V to 3.6V and 5V) with a 200 kSPS sampling rate and external reference configuration, communicating via SPI interface.

The ADS7841ES/2K5 carries an Obsolete product status. Direct substitution requires identifying active production alternatives that maintain identical electrical and mechanical specifications while ensuring compatibility with existing circuit designs and supply chain requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ADS7841ES/2K5 is determined by strict equivalence across the following critical parameters:

• 12-bit resolution and 200 kSPS sampling rate
• 4 single-ended input channels with SAR architecture
• SPI digital interface with MUX-S/H-ADC configuration
• External reference voltage requirement
• Dual supply voltage compatibility (2.7V to 3.6V and 5V ranges)
• 16-SSOP surface mount package with identical 3.90mm width
• Operating temperature range of -40°C to 125°C
• ROHS3 compliance and REACH unaffected status

All identified substitute parts maintain these specifications without deviation. Variations in packaging format (Tube, Cut Tape & Digi-Reel, or unspecified), product status (Active vs. Obsolete), and automotive qualification (AEC-Q100) represent secondary differentiators that do not affect core electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Non-Automotive Applications):

ADS7841ES, ADS7841E/2K5, and ADS7841EB/2K5 are direct electrical and mechanical equivalents with Active product status. These parts maintain identical electrical specifications and 16-SSOP packaging. Selection among these three depends on packaging format availability and supply chain requirements. ADS7841E/2K5 offers the highest inventory level (12,800 units) in Cut Tape & Digi-Reel format, suitable for high-volume production environments. ADS7841EB/2K5 provides the largest available stock (22,614 units) in unspecified packaging. ADS7841ES in Tube packaging offers intermediate inventory (1,349 units).

Automotive-Grade Substitutes:

ADS7841EIDBQRQ1 and ADS7841ESQDBQRQ1 are AEC-Q100 qualified variants with elevated MSL rating (3, 168 Hours) and Active product status. These parts are electrically and mechanically identical to the primary substitutes but include automotive-grade qualification. Selection of automotive variants is required only for applications subject to automotive industry standards or reliability requirements exceeding commercial-grade specifications.

All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with the original ADS7841ES/2K5.

Frequently Asked Questions (FAQ)

Q: Can ADS7841ES replace ADS7841ES/2K5 directly?

A: Yes. ADS7841ES is electrically and mechanically identical, with identical 12-bit resolution, 200 kSPS sampling rate, 4 single-ended inputs, SPI interface, and 16-SSOP package. The primary difference is product status (Active vs. Obsolete) and packaging format (Tube vs. unspecified). No circuit modifications are required.

Q: What is the difference between ADS7841E/2K5 and ADS7841EB/2K5?

A: Both parts are parametrically equivalent with identical electrical specifications and 16-SSOP packaging. The difference lies in packaging format (Cut Tape & Digi-Reel vs. unspecified) and available inventory levels. Selection depends on production volume requirements and supply chain logistics.

Q: When should I use ADS7841EIDBQRQ1 or ADS7841ESQDBQRQ1?

A: These automotive-grade variants (AEC-Q100 qualified) are required for applications subject to automotive industry standards or demanding reliability specifications. Both maintain identical electrical and mechanical specifications to non-automotive variants but include enhanced qualification and MSL rating (3 vs. 2).

Q: Are all substitute parts in the same 16-SSOP package?

A: Yes. All substitute parts use the 16-SSOP (0.154", 3.90mm Width) surface mount package. Pin-to-pin compatibility is maintained across all variants, enabling direct PCB layout reuse without modification.

Q: What is the MSL difference between standard and automotive variants?

A: Standard variants (ADS7841ES, ADS7841E/2K5, ADS7841EB/2K5) carry MSL rating 2 (1 Year). Automotive variants (ADS7841EIDBQRQ1, ADS7841ESQDBQRQ1) carry MSL rating 3 (168 Hours), indicating enhanced moisture sensitivity protection suitable for automotive manufacturing environments.

Q: Can I mix packaging formats in production?

A: Yes. All substitute parts are electrically and mechanically identical. Packaging format differences (Tube, Cut Tape & Digi-Reel, or unspecified) do not affect component functionality or circuit performance. Selection is based on production equipment compatibility and supply chain requirements.
