TLV2341IDR Equivalent & Substitute Parts

Part Overview

The TLV2341IDR is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device is classified as obsolete, indicating discontinued production and limited availability through standard distribution channels. The LinCMOS™ series design provides low-power operation suitable for battery-powered and portable applications. Due to its obsolete status, identifying functionally compatible substitute components is essential for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV2341IDR is determined by the following critical parameters:

Package Compatibility: Both the main part and substitute must use the 8-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm Width) to ensure direct PCB footprint compatibility without layout modifications.

Functional Classification: The substitute must be classified as a general-purpose operational amplifier with a single circuit configuration to maintain equivalent functional behavior in typical application circuits.

Electrical Operating Range: The substitute must support the operating temperature range of -40°C to 85°C and provide compatible supply voltage specifications to function within existing power distribution architectures.

Output Drive Capability: The substitute must deliver sufficient output current per channel (minimum 27 mA) to meet load requirements of the original design.

Regulatory Compliance: Both parts must maintain ROHS3 compliance and REACH unaffected status to satisfy procurement and environmental requirements.

The MC33171DR2G from onsemi meets all substitution criteria through identical package geometry, matching functional classification, compatible temperature range, and equivalent regulatory certifications.

Engineering Selection Recommendations

Availability and Product Status: The TLV2341IDR is classified as obsolete with limited inventory. The MC33171DR2G is an active product with 31,500 units in stock, providing superior long-term availability and supply chain reliability for new designs and production continuity.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and regulatory requirements for industrial and commercial applications.

Package and Mounting Compatibility: Identical 8-SOIC package specifications ensure direct PCB footprint compatibility without layout redesign or assembly process modifications.

Electrical Performance Considerations: The MC33171DR2G operates across a wider supply voltage range (3V to 44V versus 2V to 8V), providing greater flexibility in multi-voltage system designs. The substitute exhibits lower quiescent current consumption (220µA versus 675µA), beneficial for battery-powered applications. Output current capability remains equivalent (27mA versus 30mA), meeting typical load requirements.

Selection Basis: Component selection should prioritize the MC33171DR2G for new designs and production applications due to active product status, superior availability, and regulatory compliance alignment with the original TLV2341IDR specification.

Frequently Asked Questions (FAQ)

Q: Can the MC33171DR2G directly replace the TLV2341IDR without PCB modifications?

A: Yes. Both components use identical 8-SOIC package geometry with matching pin configurations and physical dimensions. Direct PCB footprint compatibility is confirmed.

Q: What are the key electrical differences between these parts?

A: The MC33171DR2G operates across a wider supply voltage range (3V to 44V) compared to the TLV2341IDR (2V to 8V). The substitute exhibits lower supply current (220µA versus 675µA) and slightly lower slew rate (2.1V/µs versus 3.6V/µs). Output current capability is equivalent (27mA versus 30mA).

Q: Why is the TLV2341IDR listed as obsolete?

A: Obsolete status indicates Texas Instruments has discontinued production. Existing inventory may be available through authorized distributors, but long-term supply cannot be guaranteed.

Q: Are there any compliance concerns with substitution?

A: No. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent substitution.

Q: Which part should be selected for new designs?

A: The MC33171DR2G is recommended for new designs due to active product status, confirmed long-term availability, and equivalent functional performance within the specified operating parameters.

Q: Does the lower slew rate of the MC33171DR2G affect circuit performance?

A: Slew rate differences (2.1V/µs versus 3.6V/µs) may impact high-frequency signal conditioning applications. Circuit-level evaluation is necessary if slew rate is a critical design parameter.

Q: What is the minimum supply voltage requirement for the MC33171DR2G?

A: The MC33171DR2G requires a minimum supply voltage of 3V, compared to 2V for the TLV2341IDR. Designs operating below 3V supply voltage cannot use this substitute.
