TLV2452IP Equivalent & Substitute Parts

Part Overview

The TLV2452IP is a general-purpose operational amplifier manufactured by Texas Instruments, featuring dual circuits with rail-to-rail output capability in an 8-pin DIP package. This device is classified as Last Time Buy, indicating discontinued production with limited inventory availability. The TLV2452IP is designed for low-power applications requiring dual amplifier channels with supply voltages between 2.7V and 6V across an extended operating temperature range of -40°C to 125°C.

Identifying equivalent substitute parts is necessary due to the Last Time Buy status of the TLV2452IP. As original inventory depletes, alternative configurations of the same base product family provide functional continuity while accommodating different manufacturing and assembly requirements.

Substitute Part Grouping Explanation

Substitution of the TLV2452IP is determined by electrical parameter equivalence and functional compatibility. The TLV2452 base product family maintains identical electrical specifications across package variants, ensuring direct functional substitution when mechanical constraints permit.

The primary substitution criterion is the preservation of all electrical parameters: dual general-purpose amplifier circuits, rail-to-rail output, identical slew rate (0.11 V/µs), gain bandwidth product (220 kHz), input bias current (500 pA), input offset voltage (300 µV), supply current (23 µA per channel), output current capability (10 mA per channel), and supply voltage range (2.7V to 6V). Operating temperature range (-40°C to 125°C) and compliance certifications (ROHS3, REACH Unaffected, EAR99) must remain constant.

The TLV2452IDR represents the surface-mount equivalent of the TLV2452IP, differing only in mounting technology and packaging format while maintaining complete electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

The TLV2452IDR serves as the direct functional substitute for the TLV2452IP when design constraints permit surface-mount implementation. Both devices maintain identical electrical performance specifications and regulatory compliance certifications.

Selection between TLV2452IP and TLV2452IDR is determined by printed circuit board assembly technology and mechanical layout requirements. The TLV2452IP accommodates through-hole soldering processes and breadboard prototyping applications. The TLV2452IDR is specified for surface-mount assembly, offering reduced board footprint and automated manufacturing compatibility.

The TLV2452IDR carries Active product status, ensuring continued availability and manufacturing support. The TLV2452IP, classified as Last Time Buy, has limited inventory (3,146 pieces) and represents a declining supply condition. For new designs or production quantities requiring long-term component availability, the TLV2452IDR is the appropriate selection.

Both devices satisfy ROHS3 compliance and REACH regulatory requirements. Electrical performance is identical across all specified parameters, including supply voltage range (2.7V to 6V), operating temperature range (-40°C to 125°C), and all amplifier characteristics.

Frequently Asked Questions (FAQ)

Q: Are the TLV2452IP and TLV2452IDR electrically identical?

A: Yes. Both devices share the same base product number (TLV2452) and maintain identical electrical specifications across all parameters: dual general-purpose amplifier circuits, rail-to-rail output, 0.11 V/µs slew rate, 220 kHz gain bandwidth product, 500 pA input bias current, 300 µV input offset voltage, 23 µA supply current per channel, 10 mA output current per channel, and 2.7V to 6V supply voltage range. Operating temperature range (-40°C to 125°C) is identical.

Q: What is the primary difference between these two parts?

A: The TLV2452IP uses through-hole mounting (8-DIP package, 0.300" width) while the TLV2452IDR uses surface-mount technology (8-SOIC package, 0.154" width). Packaging format differs: TLV2452IP is supplied in Tube format; TLV2452IDR is supplied in Cut Tape and Digi-Reel format.

Q: Can I use TLV2452IDR as a direct replacement for TLV2452IP on existing circuit boards?

A: Direct board-level substitution is not possible without redesign. The TLV2452IP requires through-hole PCB pads and soldering processes, while the TLV2452IDR requires surface-mount pads and reflow soldering. Pin-to-pin electrical function is identical, but physical footprints are incompatible.

Q: Why is the TLV2452IP classified as Last Time Buy?

A: Last Time Buy status indicates Texas Instruments has discontinued production of this device. Existing inventory is available for purchase, but no future manufacturing runs are planned. Once inventory depletes, the part will become unavailable.

Q: Should I transition to TLV2452IDR for new designs?

A: For new product designs, the TLV2452IDR is the appropriate selection. It maintains identical electrical performance while offering Active product status, ensuring long-term availability and manufacturing support. Surface-mount technology is standard in modern PCB assembly processes.

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

A: No. Both devices carry identical regulatory certifications: ROHS3 Compliant, REACH Unaffected, and EAR99 classification. Compliance status is equivalent.

Q: What is the moisture sensitivity level (MSL) for each part?

A: The TLV2452IP has MSL listed as Not Applicable. The TLV2452IDR has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for the surface-mount variant.

Q: Can I use either part interchangeably in circuit design calculations?

A: Yes. For circuit design purposes, both parts are electrically equivalent. All amplifier specifications, performance parameters, and operating conditions are identical. Circuit design calculations, PCB layout considerations for signal integrity, and power supply requirements are the same for both variants.
