TLV2450CD Equivalent & Substitute Parts

Part Overview

The TLV2450CD is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device features rail-to-rail output capability and is designed for low-power applications requiring single-circuit amplification. The TLV2450CD is classified as obsolete, which necessitates identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain electrical and mechanical compatibility while offering continued availability and support.

Parameter Comparison

Engineering Selection Recommendations

The TLV2450AIDR is the direct functional equivalent of the TLV2450CD. Both components share identical electrical specifications, mechanical packaging, and regulatory compliance certifications. The primary distinction is product status: the TLV2450CD is obsolete, while the TLV2450AIDR is an active product with ongoing manufacturer support from Texas Instruments.

The TLV2450AIDR offers an extended operating temperature range (-40°C ~ 125°C) compared to the TLV2450CD (0°C ~ 70°C), providing broader environmental capability without compromising core electrical performance. This extended range does not restrict application in designs originally specified for the TLV2450CD.

Both components are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings. The TLV2450AIDR is supplied in Tape & Reel packaging format, which is standard for production environments and automated assembly processes.

For new designs and production continuity, the TLV2450AIDR is the appropriate selection. Existing designs using the TLV2450CD can transition to the TLV2450AIDR without circuit modification, as all electrical and mechanical parameters remain equivalent.

Frequently Asked Questions (FAQ)

Q: Can the TLV2450AIDR be used as a direct replacement for the TLV2450CD in existing designs?

A: Yes. The TLV2450AIDR is electrically and mechanically equivalent to the TLV2450CD. All core operational parameters—slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range—are identical. The 8-SOIC package dimensions and pinout are unchanged. No circuit modifications are required.

Q: What is the difference between the TLV2450CD and TLV2450AIDR?

A: The primary differences are product status and operating temperature range. The TLV2450CD is classified as obsolete and operates from 0°C to 70°C. The TLV2450AIDR is an active product with extended operating temperature range from -40°C to 125°C. Both share identical electrical specifications and packaging.

Q: Why is the TLV2450CD obsolete?

A: Product obsolescence is determined by the manufacturer based on market demand, production economics, and technology evolution. The TLV2450AIDR remains in active production and is the recommended component for all new applications.

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

A: No. Both the TLV2450CD and TLV2450AIDR are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited). Regulatory compliance is equivalent.

Q: What packaging formats are available for the TLV2450AIDR?

A: The TLV2450AIDR is supplied in Tape & Reel (TR) format, which is standard for automated assembly and production environments. This differs from the TLV2450CD, which was available in bulk packaging.

Q: Can the extended temperature range of the TLV2450AIDR affect circuit performance?

A: The extended operating temperature range (-40°C ~ 125°C) of the TLV2450AIDR does not alter electrical performance within the original specification range (0°C ~ 70°C). The component maintains all specified parameters across its full operating range. Applications designed for the TLV2450CD will operate identically when using the TLV2450AIDR.

Q: Is the 8-SOIC package identical between both parts?

A: Yes. Both components use the 8-SOIC package with identical dimensions (0.154" width, 3.90mm). PCB footprints, land patterns, and assembly processes are unchanged.
