Why this 1.27 mm pitch header exists
The 5-104693-2 is a 20-position, 2-row board-to-board header from the AMPMODU 50/50 Grid series. Its 1.27 mm pitch and 0.5 A per contact rating target dense signal interconnects where a standard 2.54 mm pitch would waste board real estate. Mated stack height is fixed at 9.91 mm, which sets the board-to-board spacing for mezzanine or parallel-board layouts.
Board lock and SMT termination for reflow assembly
Board locks on the SMT package anchor the header during reflow, preventing skew from paste wetting forces. After soldering, the locks resist shear loads from cable strain or vibration — relevant for the automotive and military applications listed for this part.
RoHS3 compliant per the ledger entry. No known functional replacement from TE Connectivity — the 5-104693-2 is the current offering in this pitch and position count.
The 5-104693-2 is a 20-position, 2-row, SMT header at 1.27 mm pitch, rated 0.5 A per contact — two different density and power classes. They are not cross-shop candidates; the selection depends on board space and current budget.
