2.50 mm Pitch, 4-Position Signal Double Lock Header
The 917724-4: Tin is suitable for moderate-cycle applications (50-100 mates) in clean, indoor environments. It holds the connector pair together under light vibration and cable tug, though it is not a secondary lock like a TPA.
Through-Hole Mounting and Mated Stack Height
Mounts through-hole with kinked pins for solder retention during wave soldering. The contact length — 0.185" (4.70 mm) mating side and 0.126" (3.20 mm) post — sets the board thickness range and the receptacle insertion depth. The insulation height of 0.602" (15.29 mm) means the header stands tall above the board; plan for component keep-out zones around the connector body.
The base product number is 917724; the -4 suffix indicates the 4-position variant. No official pin-compatible alternative is listed by TE, but the Signal Double Lock family includes other position counts and plating options if your design allows a change.
