TLV2401IP Equivalent & Substitute Parts

Part Overview

The TLV2401IP is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-pin DIP package for through-hole mounting. This device features rail-to-rail output capability and operates across a wide supply voltage range of 2.5V to 16V, making it suitable for low-power analog signal processing applications. The TLV2401IP is currently classified as Last Time Buy, indicating discontinued production status. Identifying equivalent substitute parts is essential for design continuity, long-term component sourcing, and production planning when original inventory becomes unavailable.

Substitute Part Grouping Explanation

Substitution of the TLV2401IP is determined by electrical and functional equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 1
• Output Type: Rail-to-Rail
• Slew Rate: 0.0025 V/µs
• Gain Bandwidth Product: 5.5 kHz
• Current - Input Bias: 100 pA
• Voltage - Input Offset: 390 µV
• Current - Supply: 900 nA
• Current - Output / Channel: 200 µA
• Voltage - Supply Span: 2.5V to 16V
• Operating Temperature Range: -40°C to 125°C

Functional Equivalence Criteria:

• Base Product Number: TLV2401
• Manufacturer: Texas Instruments
• RoHS3 Compliance
• REACH Unaffected Status

The TLV2401IDR is a direct functional equivalent that maintains identical electrical specifications while differing only in packaging format and mounting technology. This substitution is valid for applications where the mounting method can be adapted from through-hole to surface-mount assembly.

Engineering Selection Recommendations

TLV2401IDR Selection Criteria:

The TLV2401IDR is the direct substitute for the TLV2401IP when the following conditions are met:

1. Assembly Technology Compatibility: The design must support surface-mount assembly. The TLV2401IDR uses 8-SOIC packaging, requiring PCB footprints and reflow soldering processes compatible with surface-mount technology.

2. Product Status Advantage: The TLV2401IDR maintains Active product status with Texas Instruments, ensuring continued availability and long-term supply chain stability compared to the Last Time Buy status of the TLV2401IP.

3. Compliance Alignment: Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for equivalent substitution.

4. Electrical Specification Equivalence: All electrical parameters, including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current capability, and supply voltage range, are identical between the two parts.

5. Packaging Format: The TLV2401IDR is supplied in Tape & Reel format, suitable for automated assembly operations, whereas the TLV2401IP is supplied in Tube format for manual or semi-automated through-hole insertion.

Design Transition Path:

For new designs or design revisions, the TLV2401IDR is the recommended selection due to its active product status and surface-mount compatibility. For existing through-hole designs, substitution requires PCB redesign to accommodate 8-SOIC footprint and surface-mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the TLV2401IDR be used as a direct pin-for-pin replacement for the TLV2401IP?

A: No. While both parts are electrically equivalent, they differ in package type and mounting technology. The TLV2401IP uses 8-DIP through-hole packaging, while the TLV2401IDR uses 8-SOIC surface-mount packaging. Pin-for-pin replacement is not possible without PCB redesign and assembly process changes.

Q: What are the key electrical differences between TLV2401IP and TLV2401IDR?

A: There are no electrical differences. Both parts share identical specifications for slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, supply voltage range, and operating temperature range.

Q: Why is the TLV2401IP classified as Last Time Buy?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of this part number. Existing inventory is available for purchase, but no future production runs are planned. The TLV2401IDR, with identical electrical specifications and active product status, is the recommended alternative for future designs.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both the TLV2401IP and TLV2401IDR maintain ROHS3 compliance and REACH Unaffected status. They share identical ECCN (EAR99) and HTSUS (8542.33.0001) classifications.

Q: What is the primary advantage of substituting to TLV2401IDR?

A: The primary advantage is supply chain continuity. The TLV2401IDR maintains Active product status with Texas Instruments, ensuring long-term availability. Additionally, surface-mount technology offers manufacturing efficiency benefits for high-volume production compared to through-hole assembly.

Q: Can I use the TLV2401IDR in a through-hole design without modification?

A: No. The TLV2401IDR requires surface-mount assembly and cannot be inserted into through-hole PCB footprints designed for the 8-DIP package. Substitution requires PCB redesign and assembly process adaptation.

Q: What is the moisture sensitivity level difference between these parts?

A: The TLV2401IP has Not Applicable moisture sensitivity level, while the TLV2401IDR has MSL 1 (Unlimited). This indicates the TLV2401IDR has minimal moisture sensitivity and does not require special storage or handling precautions.

Q: Are the supply voltage ranges identical?

A: Yes. Both parts operate across the identical supply voltage range of 2.5V to 16V, maintaining full electrical equivalence across all operating conditions.
