TLV2453CD Equivalent & Substitute Parts

Part Overview

The TLV2453CD is a general purpose operational amplifier featuring dual circuits with rail-to-rail output capability in a 14-SOIC surface mount package. This device is manufactured by Texas Instruments and is classified as obsolete. The TLV2453CD is designed for low-power applications requiring dual amplifier channels with specified gain bandwidth and slew rate characteristics.

Due to its obsolete product status, locating equivalent or substitute components is necessary for ongoing production support, design updates, and inventory replenishment. Active alternatives with identical electrical and mechanical specifications are available to ensure design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2453CD is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameter Equivalence:

• Amplifier type: General Purpose
• Number of circuits: 2
• Output type: Rail-to-Rail
• 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 per channel: 10 mA
• Supply voltage range: 2.7 V to 6 V
• Operating temperature: 0°C to 70°C

Mechanical Parameter Equivalence:

• Package type: 14-SOIC
• Package dimensions: 0.154" width (3.90 mm)
• Mounting type: Surface Mount

Compliance Equivalence:

• RoHS3 Compliant
• Moisture Sensitivity Level 1
• REACH Unaffected status

The TLV2453CDR qualifies as a direct substitute based on complete alignment with all specified parameters. The primary distinction is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The TLV2453CDR is the direct substitute for the obsolete TLV2453CD. Both components share identical electrical specifications, mechanical dimensions, and compliance certifications. The TLV2453CDR maintains active product status with Texas Instruments, ensuring long-term availability and supply chain continuity.

Selection Basis:

The substitution is supported by:

• Complete electrical parameter equivalence across all specified characteristics
• Identical 14-SOIC package dimensions and surface mount configuration
• Matching RoHS3 compliance and Moisture Sensitivity Level 1 rating
• Active product status of the substitute part, eliminating obsolescence risk
• Identical base product number (TLV2453) confirming design compatibility

The only distinction between the two parts is the packaging format: the TLV2453CD is supplied in tube packaging, while the TLV2453CDR is supplied in Tape & Reel format. This difference does not affect electrical performance or mechanical compatibility in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can the TLV2453CDR be used as a direct replacement for the TLV2453CD in existing designs?

A: Yes. The TLV2453CDR is electrically and mechanically identical to the TLV2453CD. All electrical parameters, package dimensions, and compliance certifications match exactly. The component can be substituted without circuit modification.

Q: What is the difference between the TLV2453CD and TLV2453CDR?

A: The primary difference is packaging format. The TLV2453CD is supplied in tube packaging, while the TLV2453CDR is supplied in Tape & Reel (TR) format. Both contain identical die and electrical specifications. The packaging difference affects handling and automated assembly processes but not electrical performance.

Q: Why is the TLV2453CD listed as obsolete?

A: The TLV2453CD has been discontinued by Texas Instruments. The TLV2453CDR remains in active production and serves as the current equivalent for new designs and production support.

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

A: No. Both the TLV2453CD and TLV2453CDR carry identical RoHS3 compliance, Moisture Sensitivity Level 1 rating, REACH Unaffected status, and ECCN/HTSUS classifications.

Q: What is the operating temperature range for both parts?

A: Both the TLV2453CD and TLV2453CDR operate across the temperature range of 0°C to 70°C.

Q: Can the TLV2453CDR be used in high-volume production?

A: Yes. The TLV2453CDR is supplied in Tape & Reel format, which is standard for automated pick-and-place assembly in high-volume manufacturing environments.

Q: What supply voltage range is supported by both parts?

A: Both the TLV2453CD and TLV2453CDR support a supply voltage range of 2.7 V to 6 V, making them suitable for single-cell battery applications and low-voltage systems.

Q: Are the pin configurations identical between the two parts?

A: Yes. Both parts use the 14-SOIC package with identical pin assignments and functionality. No PCB layout modifications are required for substitution.
