OPA353UA Overview

What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.

Key Features

Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.

Target Applications

Microcontrollers — design-in and field replacement
BOM scrub where only the base prefix is known but suffix is TBD
Second-source checks when the original MPN is constrained

Ordering Variants

Compare 2 OPA353UA part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.

Part Number	Description	Manufacturer	Lifecycle	RoHS	Availability	Action
OPA353UA	1-Ch Op Amp, 44MHz BW, 2.7-5.5V, Rail-to-Rail, CMOS, 8-SOIC	Texas Instruments	Active	Compliant	In Stock	RFQ
OPA353UA/2K5	44MHz Op Amp, Single-Supply, Rail-to-Rail, 22V/µs Slew Rate, 8-SOIC	Texas Instruments	Active	Compliant	In Stock	RFQ

How suffixes on OPA353UA map to package, grade, and reel options.

How to Choose the Right OPA353UA Microcontrollers

📦

Match the footprint first

Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For OPA353UA, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.

🌡️

Temp grade letter matters

Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.

🔢

Copy the full MPN

Do not BOM only "OPA353UA" — include the full suffix (e.g. 2K5). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the OPA353UA product family.

Is OPA353UA a single part I can order, or a family prefix?

OPA353UA is a base / family code from Texas Instruments. You order a full MPN such as OPA353UA, OPA353UA/2K5. The variant table lists 2 orderable lines with different suffixes.

What do the suffix letters on OPA353UA part numbers mean?

Listed suffix fragments include: 2K5. Typically they encode package (see Package column), temperature grade, and tape/reel option. Always decode on the Texas Instruments datasheet ordering guide — do not guess from pattern alone.

What is the lifecycle status of OPA353UA variants?

Lifecycle values in our listing: Active. Status is per MPN suffix — one variant can be Active while another is NRND. Check PCN for your exact suffix before multi-year commitments.

What should I send for an RFQ on OPA353UA?

Full manufacturer MPN (not just OPA353UA), quantity, needed date code, reel vs tube, and any compliance docs (CoC, RoHS, conflict minerals). If you only know the base prefix, include a photo of the existing label or reel.

Where is the OPA353UA datasheet?

Use the datasheet link in the page header. Cross-check electrical curves (SOA, saturation voltage, etc.) against your operating point — the table summarizes order codes, not every graph in the PDF.
