Product details

Board Stacking at 1.5mm with a Shielded 44-Position Receptacle

The Hirose DF40GL-44DS-0.4V(58) is a 44-position, 2-row receptacle with center strip contacts, designed for mezzanine board-to-board stacking at a mated height of 1.5mm. The 0.40mm pitch packs 44 circuits into a compact footprint, but that tight pitch means the board layout needs careful trace routing — the keep-out zone around the footprint is tight, and routing a full 44 signals between two 0.40mm-spaced pads takes a disciplined fan-out. The shielded construction and gold-plated contacts (1.97µin thickness) point to this being used in high-speed or RF signal paths where crosstalk and corrosion resistance matter.

SMT Mounting and Solder Retention

The solder retention tabs on the shield take the shear load from cable or board handling after reflow — they're not just for alignment. The Tape & Reel packaging (Cut Tape also available) feeds into standard pick-and-place lines.

Frequently asked questions

Is DF40GL-44DS-0.4V(58) compatible with DF40 series plugs?

Yes, the DF40GL-44DS-0.4V(58) receptacle mates with the DF40GL-44DP-0.4V(51) or DF40GL-44DP-0.4V(58) header from the same DF40GL series. Both share the same 0.40mm pitch, 44 positions, and 2-row configuration. The 1.5mm mated stack height is fixed by this pair.

What is the stacking height of DF40GL-44DS-0.4V(58)?

The mated stacking height is 1.5mm when paired with the matching DF40GL series header. This is a fixed height — no shimming or adjustment.
