KSZ8873RLLI 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 KSZ8873RLLI part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.

How to Choose the Right KSZ8873RLLI 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 KSZ8873RLLI, 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 "KSZ8873RLLI" — include the full suffix (e.g. TR). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the KSZ8873RLLI product family.

Is KSZ8873RLLI a single part I can order, or a family prefix?

KSZ8873RLLI is a base / family code from Microchip Technology. You order a full MPN such as KSZ8873RLLI, KSZ8873RLLI-TR. The variant table lists 2 orderable lines with different suffixes.

What do the suffix letters on KSZ8873RLLI part numbers mean?

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

What is the lifecycle status of KSZ8873RLLI 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 KSZ8873RLLI?

Full manufacturer MPN (not just KSZ8873RLLI), 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 KSZ8873RLLI 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.
