Product details

The Molex 5015942011 is a 20-position plug from the SlimStack 501594 series, designed as a board-to-board interconnect with outer shroud contacts. The 0.016" (0.40mm) pitch and dual-row layout pack 20 circuits into a compact footprint, while the 0.028" (0.71mm) height above board and 0.9mm mated stacking height keep the assembly low-profile — suited for mezzanine stacking in portable or space-constrained electronics where every millimeter of z-height matters.

Fit and Footprint Decisions

At 0.40mm pitch, the board layout needs tight trace routing and small vias — this is not a forgiving footprint for hand-soldering; it expects a controlled SMT process. Solder retention features help keep the connector aligned during reflow — at this pitch, even slight skew can misalign the whole row.

Frequently asked questions

What is the pitch of 5015942011?

The pitch is 0.016" (0.40mm), which is the tightest in the SlimStack 501594 series and drives the board footprint for trace routing and via placement.

Does 5015942011 support solder retention?

Yes, the connector includes solder retention features that hold it in place during the reflow process, reducing the risk of skew or tombstoning at this fine pitch.

What is the mating connector for 5015942011?

The 5015942011 is a plug with outer shroud contacts; it mates with the matching SlimStack 501594 receptacle (same series, opposite gender). Confirm the position count and stack height match your board-to-board gap.
