Sizing the Board Footprint Without the Peg
Molex 87858-0750 is a 2 mm SRSW (single-row, single-width) horizontal SMT header — the 'W/O PEG' suffix means the plastic body has no board-lock peg, so the part relies entirely on the solder joints for shear retention during reflow and cable strain. That matters if your board sees vibration or the mating cable gets tugged: without the peg, the SMT pads carry the full mechanical load. Box packaging suggests loose-tube or tray delivery — not tape-and-reel — so plan for hand or pick-and-place handling that can accommodate a tube or tray feeder.
Lifecycle and Compliance — Active and Clean
ROHS3 compliance is confirmed, so the part meets the current EU restriction levels for lead, mercury, and the other five substances.
