LNK3604D 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: SO-8CSingle 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

How to Choose the Right LNK3604D AC DC Converters and Offline Switchers

📦

Match the footprint first

Packages here: SO-8C. Open the land-pattern drawing before you substitute a different suffix.

⚡

Electrical headroom

Compare voltage and current columns in the variant table. For LNK3604D, 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 "LNK3604D" — include the full suffix (e.g. TL). RFQ with reel/tube preference and required date code.

Frequently Asked Questions

Common technical questions about the LNK3604D product family.

Is LNK3604D a single part I can order, or a family prefix?

LNK3604D is a base / family code from Power Integrations. You order a full MPN such as LNK3604D, LNK3604D-TL. The variant table lists 2 orderable lines with different suffixes.

What do the suffix letters on LNK3604D part numbers mean?

Listed suffix fragments include: TL. Typically they encode package (SO-8C), temperature grade, and tape/reel option. Always decode on the Power Integrations datasheet ordering guide — do not guess from pattern alone.

What is the lifecycle status of LNK3604D 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 LNK3604D?

Full manufacturer MPN (not just LNK3604D), 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.
