PGA ZIF Socket for High-Pin-Count ICs
The TE Connectivity 2041549-1 is a 350-position (35×36) PGA ZIF (zero insertion force) socket from the DMD series, designed to accept high-pin-count PGA devices without damaging their delicate pins during insertion or removal. The ZIF mechanism — actuated by a lever or cam — opens the contacts wide enough for the PGA device to drop in freely, then closes to grip each pin with a wiping action that cleans the interface. Rated at 500 mA per circuit, this socket is suited for signal-level duty — logic lines, address/data buses, and GPIO — not for power pins carrying more than half an amp.
The Closed Frame design means the socket body fully surrounds the contact area, providing mechanical support and preventing debris ingress during handling. Termination is surface-mount, with tin-lead finish on the post side. The SMT footprint requires a reflow profile compatible with the LCP housing's heat deflection — the solder joints are on the board side, while the ZIF mechanism and mating contacts remain above the board surface.
The base product number is 2041549, so any future variant or packaging option will share that root. The DMD series includes other position counts, but a 350-position (35×36) grid is specific to this variant.
