Power Integrations LNK6666K
LNK6666K variants from Power Integrations
LNK6666K Overview
What changes between part numbers, and what to check before you lock the BOM — AC DC Converters and Offline Switchers.
Key Features
- Footprint / package: eSOP-12BSingle package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
Target Applications
- AC DC Converters and Offline Switchers — 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 LNK6666K part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.

How to Choose the Right LNK6666K AC DC Converters and Offline Switchers
Match the footprint first
Packages here: eSOP-12B. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For LNK6666K, 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 "LNK6666K" — include the full suffix (e.g. TL). RFQ with reel/tube preference and required date code.
