TLV2254QDREP Equivalent & Substitute Parts

Part Overview

The TLV2254QDREP is a general-purpose operational amplifier featuring four independent circuits in a 14-SOIC surface mount package. This device is classified as obsolete, necessitating identification of active equivalent components for new designs and production continuity. The TLV2254QDREP operates across a wide supply voltage range of 2.7V to 16V with rail-to-rail output capability, making it suitable for low-power analog signal processing applications. Due to its obsolete status, sourcing active alternatives is essential for ongoing system support and manufacturing requirements.

Engineering Selection Recommendations

The TLV2254IDR is the direct active equivalent for the obsolete TLV2254QDREP. Both components share identical electrical performance specifications, package geometry, and compliance certifications. The TLV2254IDR is currently in active production status with established supply chain availability (6200 units in stock versus 995 units for the obsolete variant).

Supply Voltage Consideration: The TLV2254IDR specifies a maximum supply voltage of 8V, compared to 16V for the TLV2254QDREP. Applications requiring supply voltages exceeding 8V must evaluate alternative components or confirm that actual operating conditions remain within the 8V maximum specification of the substitute part.

Compliance Status: Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and manufacturing process compatibility.

Packaging: Both components utilize identical 14-SOIC surface mount packaging with matching footprint dimensions, enabling direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the TLV2254IDR directly replace the TLV2254QDREP in existing designs?

A: The TLV2254IDR provides electrical and mechanical equivalence for applications operating at supply voltages of 8V or below. If your design operates at supply voltages between 8V and 16V, the TLV2254IDR is not suitable without circuit modification or alternative component selection.

Q: What is the primary difference between these two part numbers?

A: The TLV2254QDREP is obsolete with a maximum supply voltage rating of 16V. The TLV2254IDR is the active production equivalent with a maximum supply voltage rating of 8V. All other electrical parameters, package specifications, and compliance certifications are identical.

Q: Are the PCB footprints identical?

A: Yes. Both the TLV2254QDREP and TLV2254IDR use the 14-SOIC package with identical dimensions (0.154" width, 3.90mm). No PCB layout modifications are required for substitution.

Q: What packaging format is the TLV2254IDR supplied in?

A: The TLV2254IDR is supplied in Tape & Reel (TR) format, suitable for automated assembly processes.

Q: Are there any temperature range differences?

A: No. Both parts operate across the identical temperature range of -40°C to 125°C.

Q: What compliance certifications apply to the TLV2254IDR?

A: The TLV2254IDR is ROHS3 compliant with moisture sensitivity level 1 (unlimited), matching the compliance profile of the TLV2254QDREP.
