Product details

Plug-to-Plug Adapter for In-Line Harness Routing

The Molex 2451321099 is a Micro-Fit 3.0 in-line adapter that connects two plug halves directly — both ends are male pins, so it joins two receptacle-equipped cable assemblies end-to-end without a board. It carries 10 circuits across 2 rows on a 0.118" (3.00mm) pitch, matching the standard Micro-Fit 3.0 footprint. Use it to extend a harness, create a service loop, or break a wire run at a panel junction where you need a disconnect point.

Mounting and Fit — Free-Hanging Only

This adapter is free-hanging (in-line) only — no board-mount lugs, no panel flange. The two plug bodies snap together as one unit, and each end accepts a standard Micro-Fit 3.0 receptacle housing. The 3.00mm pitch gives enough room for 20-24 AWG wire with the matching crimp terminals.

Frequently asked questions

Where can I buy the Molex 2451321099 and what is the price?

Submit an RFQ for your BOM quantity and target delivery window.

What is the Molex 2451321099 used for?

It is a plug-to-plug adapter for the Micro-Fit 3.0 series, used to join two receptacle-terminated cable assemblies in-line — no PCB required. Typical applications include extending harness runs, adding a service disconnect in a wire bundle, or routing power between enclosures where a board-to-wire connection isn't practical.

Is the 2451321099 compatible with standard Micro-Fit 3.0 receptacles?

Yes — both ends of the adapter are male pins on a 0.118" (3.00mm) pitch, 2-row layout, so they mate with any standard Micro-Fit 3.0 receptacle housing that matches the 10-position, dual-row configuration.
