Parameter Comparison

Engineering Selection Recommendations

The TLV2453IDGSR is the direct substitute for the obsolete TLV2453CDGS. Both components are manufactured by Texas Instruments and share identical electrical performance specifications and mechanical package dimensions. The TLV2453IDGSR maintains active product status, ensuring ongoing availability and supply chain continuity.

The TLV2453IDGSR provides an extended operating temperature range of -40°C to 125°C compared to the TLV2453CDGS range of 0°C to 70°C, offering broader environmental capability for applications requiring wider temperature operation. Both devices maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs.

The primary distinction between these components is packaging format: the TLV2453CDGS is supplied in bulk packaging, while the TLV2453IDGSR is supplied in Tape & Reel format. This packaging difference does not affect electrical or mechanical compatibility and reflects standard industry practice for active production components.
