Board-to-board receptacle for tight stacking
The 5-104078-4 is a 30-position, dual-row female socket receptacle from the AMPMODU System 50 series, designed for board-to-board stacking with a 0.050" (1.27mm) pitch. It mates with matching male headers to create a mezzanine connection, with supported mated stacking heights of 11.43mm and 12.57mm.
The 1A limit per circuit reflects the fine-pitch contact geometry — pushing beyond that risks temperature rise above the housing's UL94 V-0 rated thermoplastic.
