Board-to-Board Mezzanine Header — 30 Positions, 1.27mm Pitch
The 90863-115LF: The mated stack height of 6.42mm sets the z-height between parallel PCBs — a tight dimension that must match the enclosure clearance and the mating receptacle's specified stack height. The tin-plated posts (100µin) are standard for SMT solder reflow.
The base product number 90863 helps identify potential sibling variants, but no pin-compatible direct replacement has been verified.
