4-position SMT header, 0.100" pitch
The 0683011010: This is a Molex KK254 series single-row header with 4 positions on 0.100" (2.54mm) pitch, terminated by surface mount solder tails.
Surface mount footprint and board fit
The 0.100" pitch matches the standard 2.54mm grid, so the footprint aligns with common perfboard and prototyping layouts. The 0.240" (6.10mm) mating pin length provides enough reach for standard KK254 crimp receptacles. Insulation height is 0.090" (2.29mm) above the board — low enough to keep the header under a mezzanine board or cover, but tall enough to clear solder fillets on the opposite side.
