Board-to-Board Mezzanine Fit — 0.050" Pitch, 30 Positions
The 87022-615 is a dual-row, 30-position receptacle from the Rib-Cage™ series, built for board-to-board stacking. The 0.050" (1.27 mm) mating pitch and matching row spacing set a dense footprint — each pair of rows occupies the same board real estate as a single-row header at 0.100" pitch, leaving more room for trace routing between pads. BeCu holds its spring force at elevated temperature and after repeated mating cycles — the gold thickness supports several hundred cycles before the underplate sees wear. This combination suits a mezzanine interconnect that sees occasional board separation for rework or field upgrade.
It ships in a tube. No official pin-compatible equivalent is listed — the Rib-Cage™ series has several position counts, but a 30-position dual-row at 0.050" pitch is this specific order code.
