Obsolete — Sourced per RFQ
77313-122-44 carries an Obsolete lifecycle status from Amphenol ICC (FCI). No official successor part is listed on the record, so any BOM line using this header will need a board-spin or a functionally equivalent alternative confirmed against the footprint and electrical requirements. Available through independent distribution channels — quantities are lot-specific and confirmed at the time of RFQ. No stock-holding claim is made; each order is sourced against the buyer's quantity.
44-Position, 0.100" Pitch — Board Footprint Fit
This sets the board standoff and the depth the pins reach into the mating receptacle. Unshrouded breakaway style — the header can be snapped to a shorter length if the full 44 positions aren't needed, though the part ships with all positions loaded.
30.0µin Gold Mating Finish — Cycle Life
This thickness is rated for several hundred mating cycles in clean environments — suitable for field-serviceable boards where the connector is mated and unmated during maintenance, but not for frequent hot-swap or daily reconnection duty. The tin surface wets well with lead-free solder profiles.
