KSZ8873RLLI Overview
What changes between part numbers, and what to check before you lock the BOM — Microcontrollers.
KSZ8873RLLI is a Microchip Technology order-code family — not a single orderable MPN. This page lists 2 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
IC ETHERNET SWITCH I2C/SPI Other listed variants describe: IC ETHERNET SWITCH 3PORT 64LQFP.
Example MPNs: KSZ8873RLLI, KSZ8873RLLI-TR.
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.
| Part Number | Description | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|
| KSZ8873RLLI | IC ETHERNET SWITCH I2C/SPI | Microchip Technology | Active | Compliant | In Stock | |
| KSZ8873RLLI-TR | IC ETHERNET SWITCH 3PORT 64LQFP | Microchip Technology | Active | Compliant | In Stock |
Ordering Code Differences
How suffixes on KSZ8873RLLI map to package, grade, and reel options.
KSZ8873RLLI uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: TR.
Full MPN examples: KSZ8873RLLI-TR.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
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.
