144 positions at 1.80 mm pitch — the full VITA 46 pinout
The TE Connectivity 1410142-1 is a 144-position receptacle from the MULTIGIG RT2 series, configured as a VITA 41/46 right-end connector for backplane applications. The 0.071" (1.80 mm) pitch packs 144 circuits into a 9-row by 16-column grid — the standard pinout for a VITA 46 card slot. Press-fit termination means the connector presses into plated through-holes without solder, which is the preferred method for high-layer-count backplanes where rework and thermal stress are concerns. The 50.0 µ" (1.27 µm) gold contact finish supports the repeated mating cycles a line-replaceable card sees over its service life.
Right-end keying — not interchangeable with the left-end variant
The 1410142-1 is the right-end version of the MULTIGIG RT2 VITA 41/46 receptacle. The keying is defined by the connector style — right-end versus left-end — and determines which slot position in the backplane the connector occupies. Ordering the wrong end means the card does not seat. The 144 positions are fully loaded, so no positions are left unpopulated. The pitch and row count are identical across the left- and right-end variants; the difference is the guide rib location on the mating face.
