TLV2473AID Equivalent & Substitute Parts

Part Overview

The TLV2473AID is a CMOS dual-channel operational amplifier manufactured by Texas Instruments, housed in a 14-SOIC surface mount package. This device features rail-to-rail output capability and is designed for low-power analog signal processing applications requiring dual amplifier circuits in a compact form factor.

The TLV2473AID is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing production requirements, maintenance operations, and system redesigns where component availability is constrained.

Engineering Selection Recommendations

The TLV2473AIDR is the direct substitute for the TLV2473AID. Both parts are manufactured by Texas Instruments and share identical electrical specifications and mechanical packaging. The primary distinction is product status and packaging format.

TLV2473AID Status: Obsolete. This part number is no longer in active production.

TLV2473AIDR Status: Active. This part number is currently manufactured and supported by Texas Instruments.

The TLV2473AIDR is supplied in Tape & Reel (TR) packaging, which is the standard format for high-volume production and automated assembly operations. The TLV2473AID was supplied in standard packaging format.

Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring compatibility with current manufacturing and environmental standards. Selection of the TLV2473AIDR eliminates obsolescence risk and ensures access to active production inventory and manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can the TLV2473AIDR directly replace the TLV2473AID in existing designs?

A: Yes. The TLV2473AIDR is electrically and mechanically equivalent to the TLV2473AID. All electrical parameters, operating ranges, and package dimensions are identical. The device can be substituted without circuit modification or PCB redesign.

Q: What is the difference between TLV2473AID and TLV2473AIDR?

A: The primary differences are product status and packaging format. The TLV2473AID is obsolete and supplied in standard packaging. The TLV2473AIDR is active and supplied in Tape & Reel (TR) format for automated assembly. Electrical specifications and package dimensions are identical.

Q: Why is the TLV2473AIDR supplied in Tape & Reel packaging?
